Utricularia roundup, February 2016

Everyone knows that Drosera is my favorite genus of carnivorous plants. I mean, it's in the name. The number 2 spot goes back and forth – sometimes it's Pinguicula, but lately I think it's been Utricularia. It's funny, because when I was first first starting out I didn't get Utricularia at all. I had no idea why anyone would bother growing such weird, dumb little plants. Incidentally, I still feel that way about the aquatic species (but don't tell anyone).

Why Utricularia? Well, as with sundews it's a big, sprawling, cosmopolitan genus. There's a huge variety out there to explore, and several different cultivation styles to master. And of course, the flowers are a real treat, whether it's cute little spray from the easy terrestrials, or a more impressive display from larger/touchier species. Of course, the fact that very few people seem to specialize in Utricularia just makes them that much more attractive.

In any case, I decided to check in on my collection today. This collection of Utricularia lateriflora flowers got me started with the pictures.

Such delightful purple flowers.

This is one of my favorite species right now. It flowers pretty freely, and the flowers are adorable – dark purple with a white splotch.

Next door, my Utricularia cornigera is doing very well.

Those are some nice-looking leaves.

I'm glad these have recovered from dying back a few months ago. Based on how I've seen new leaves come up on this one, I feel like it would favor an airy LFS planting in a net pot. Maybe I'll do that once it gets a chance to grow in a bit more.

My other plant from section Orchidioides, Utricularia humboldtii, has put out a new leaf.

I like the venation on those leaves.

This one is pretty slow to make new leaves, but I understand that's pretty normal. I should trim all the dead growth and messy stolons to get a better picture of what it looks like. By the way, this plant has been found at elevations of more than 8000 feet (2500 meters). That's really high!

Nearby, the Utricularia heterosepala flower stalk fell over after I jostled it recently.

Man, it would be awesome if another flower popped too.

I'm seriously impressed with this plant. It's been holding both of the flowers for a while now, and there's no sign of giving up. Really fantastic grower, looking forward to getting more blooms from it.

Utricularia calycifida has a somewhat similar flower, although the bloom stalks typically support only one at a time.

This flower has awesome patterning on it.

This is the first time it's rebloomed since the last big show. I really feel like I should repot this plant into pure LFS. It's been so hard to find time to do serious plant stuff like that lately! Alas.

One of the plants that I've never been able to flower is Utricularia praelonga.

This is one of those plants just just hangs out, waiting to do something.

This oddball utric grows two different kinds of leaves, and is notoriously difficult to flower. I've seen some in bloom in cultivation though, and I'm trying to get some tips. The flowers are supposed to be large and yellow.

Utricularia sandersonii is one that flowers for me, but very weakly. This first pot has had like 2 flowers, and is covered in a really robust moss of some sort that I do not like.

Seriously overgrown pot.

Whereas in this next pot, it's definitely losing the fight to Utricularia subulata.

REALLY seriously overgrown pot.

Not sure what the problem is with this one for me. I know people who can't help but get a big carpet of bunnies. Maybe I should try some in a windowsill.

Speaking of U. subulata, my big, proper bloom is looking so good right now.

U. subulata always breaks your heart.

I wish wish wish it would do this all the time. This is a fantastic flower! Ah well. Maybe the fleeting quality of it makes it more special.

One thing I did recently was break up a few of my well-established plants to share around and propagate. Here's my Utricularia gramnifolia getting started again.

Looking forward to this filling in and blooming again.

The submerged aquatic setup in an undrained pot seems to work pretty well for this plant. I suspect a lot of the terrestrials would like this treatment, actually. Might be fun to try them in teacups, like the Carnivore Girl.

This tray has starts from some of the pots I broke up, as well as a couple new specimens I'm just getting started.

So much promise in these pots!

Clockwise from top left: Utricularia 'Betty's Bay' (a large-flowered form U. bisquamata), Utricularia blanchetii, Utricularia fulva, Utricularia pubescens, Utricularia cornuta, Utricularia livida. I've been flooding this tray to try and jump-start these guys.

Finally, I took a picture of some U. bisquamata among my wide-leaf Drosera capensis.

I love how the flowers all face towards the lights.

It's just too cute. Even though it's a weed, it's a wonderful plant. That's true of both of them, actually. No respect at all!

Incidentally, my Utricularia longifolia is blooming. It's not in my collection right now because I brought it for display at the Pacific Orchid Expo. I'll feature that one later.

BACPS 2015 Annual Show and Sale

This past Saturday was the Bay Area Carnivorous Plant Society's Annual Show and Sale at the Lake Merritt Garden Center in Oakland, CA. It was a fun day! Unfortunately I got very little sleep the night before – one of those nights where you just stare at the ceiling in despair – so by the end of the show I was exhausted.

It was a tough weekend for a show. We were competing with the San Francisco Cactus and Succulent Society show, as well as the San Jose Orchid Exposition. In spite of that we had a very nice turnout from members of the public. However the show itself was a bit less packed with entries than we'd have liked. Sundews and pings were well-represented, as were Sarracenia. The Nepenthes entries were a bit more sparse than usual, but still contained some excellent plants. However there were zero entries in the "Other Pitcher" category, only 1 for the aquatics, 2 for Art, and just 3 in "Terrarium/Dish Garden."

We're not sure why so few plants were submitted as compared to last year, but increasing show participation is going to be a major goal for the coming year in the BACPS. Now, without further ado, the entries.

Art

First: Heliamphora nutans, pontillist drawing, Sam Stafford.

Second: Venus flytrap, metal sculpture, Benjamin Bailey.

Terrarium/Dish Garden

First: Pygmy Garden, Devon Peterson. Also Third in Show.

Second: Dish Garden featuring Pinguicula sp. Huahuapan, Stephen Davis.

Check out that amazing flower! That's a new ping to add to my want list.

Third: D. adelae, D. scorpioides, D. burmannii, Ben Raymond.

Butterwort (Pinguicula)

First: Pinguicula 'Pirouette', Doris Quick.

Second: Pinguicula 'Weser', Stephen Davis.

Third: Pinguicula gigantea, Brian Lipinski.

Sundew (Drosera, Byblis, Roridula)

First: Drosera falconeri, Apache Rose. Also First in Show.

Second: Drosera ordensis, Apache Rose.

Third: Drosera ultramafica × spatulata, Devon Peterson.

American Pitcher Plant (Sarracenia)

First: Sarracenia flava var. rubricorpora, Doris Quick.

Second: Sarracenia alata "black" × flava "red", Stephen Davis.

Third: Sarracenia hybrid, Larry Logoteta.

Tropical Pitcher Plant (Nepenthes)

First: Nepenthes spectabilis, Apache Rose. Also Second in Show and winner of the Geoff Wong Award for Horticultural Excellence.

This was really a flawlessly-grown and wonderfully-presented plant. Apache really knows how to grow 'em.

Second: Nepenthes talangensis × robcantleyi, Josh Brown.

Third: Nepenthes bongso, Elizabeth Sampson.

Aquatic

First: Utricularia graminifolia, Devon Peterson.

I was sort of bummed there weren't more aquatic entries, since I think this guy would have shown well against some competition. Oh well.


Venus Flytrap

First: Dionaea 'B-52', Benjamin Bailey.

 
Second: Dionaea 'B-52' × 'Ginormous', Larry Logoteta.

Third: Dionaea 'Red Dragon', Anne Smith.

Best in Show

I've gotta say, the real hero of the show was Apache Rose. Anyone who's active in carnivorous plant groups on Facebook knows Apache, and she really brought some killers. She also credited me with helping her get that D. falconeri so strikingly red – she raised her plant right up near the lights in the last two weeks to color it up, as I had done with my Drosera burmannii last year. It was well done!

First in Show was Drosera falconeri by Apache Rose, Second in Show was Nepenthes spectabilis by Apache Rose, and Third in Show was my own humble pygmy garden.

It was a fun show. Still, there were 5 ribbons not awarded due to lack of entries. Any SF Bay Area growers reading this post: start preparing your plants for next year.

Utricularia graminifolia flower and other cool stuff

Back at the beginning of March – 3 months ago – I first noticed a flower stalk forming on my Utricularia graminifolia. Yesterday it finally popped its first flower.

Neat little flower. Foliage is looking pretty good too.

So cute! U. graminifolia is considered one of the more fiddly terrestrial/semi-aquatic utrics. I grow mine in an undrained glass container about 18 inches from my lights. I let the water pretty much evaporate all the way before refilling almost to the top of the container (covering the plant entirely). I've heard of several people using this method to successfully grow U. graminifolia to flower. There are several more flower stalks coming up, which is exciting. One thing to note when using this method – when you first plant your plug of U. graminifolia there's nothing holding the peat together, so watering really stirs it all up. The peat settles after a day or so. Once the plant fills in the container watering isn't so much of an issue anymore.

 I've also got a flower coming up on my Drosera collinsiae (Fairyland, RSA).

Very nice rosette of leaves on this plant.

This is a really handsome plant that hasn't gotten much attention on the blog. It started to flower once before, but I clipped the stalk when I noticed aphids on it. Now we're flowering again and I'm keeping my fingers crossed that this one won't be similarly afflicted.

These next two photos I recently posted on my Instagram, but I decided to share them here too because not everyone has Instagram. First up, look at this wild picture of my Drosera burmannii (Hann River, Kimberley, Western Australia).

Dig that weird splotchy coloring.

I had let them go a while without being fed, which gave them a lovely, luminescent red color. Then, a couple days after a heavy feeding, I noticed that there was this mix of pale pink and deep red leaves as the new growth grew in. Super cool!

I also shared this photo of Drosera enodes, which I took as part of my project to improve the pygmy sundew pages on Wikipedia.

One of the loveliest pygmies, imo.

D. enodes forms this little dome composed almost entirely of dew, and it's really, really cute. I love my little pygmies.

Drosera ×"Andromeda" leaf cutting (and Utricularia graminifolia flower)

Back in January I won an auction for a Drosera cistiflora that is really doing great. The grower from whom I won the D. cistiflora also included (very generously!) two leaves of Drosera ×"Andromeda", which is Drosera schizandra × prolifera. This plant is becoming more common, but it's still fairly rare and definitely a prize in any collection. I started one cutting in water, and the other I placed on some living Sphagnum moss (that I harvested from my Drosera prolifera pot). Just the other day I noticed a strike on the water-float plant!

Leaf strike!

The one on the moss hasn't done anything yet that I can tell. Moss looks great though.

Getting my Sphagnum game in order.

I'm really looking forward to seeing this guy grow in. Then I'll just need to get my hands on some Drosera schizandra and I'll have the full Three Sisters of Queensland collection!

Another exciting development today is this flower stalk on Utricularia graminifolia.

U. graminifolia has very pretty flowers.

Okay, I know it doesn't look like much right now, but right there in the middle of the photo is a flower stalk, I promise. I guess U. graminifolia has settled into its conditions pretty well. Now I want to transition it to a shallower container. I like the idea of a really shallow glass container with a layer of flowering U. graminifolia living on it. We'll see.

Speaking of Utricularia flowers, my Utricularia longifolia flower stalk is getting taller!

This is really a beast of a plant.

It's so hard to photograph that stalk with my phone camera. I'm going to need to get something proper just so I can manually control the point of focus. The tip of the flower stalk is taking on a purple tinge though. Exciting!

Finally, in other flower news there is a stalk developing on Drosera affinis.

It curls up so elegantly.

While I'm happy it's doing so well, I'm frankly not all that optimistic about seed production. I was disappointed with both Drosera madagascariensis and Drosera venusta on that front. The only South African species that have consistently set good seed for me are Drosera capensis (obviously) and Drosera aliciae. We'll see what happens though!

Flower stalk on Utricularia calcyfida

I've got some action over in my Utricularia calycifida pot.

U. calycifida is in section Foliosa. They have bigger "leaves".

I like the little mound.

I really like this plant. It's been growing pretty solidly and spreading in the pot. Now it looks like I'm going to get a flower stalk!

I've been reading a bit about foliar fertilizing on Utricularia lately, and think maybe I should give it a shot. I feed my Drosera at least once a month, but my Utrics don't get any love. Maybe there would be even more blooming and spreading then.

Things are a little funny over in the Utricularia livida pot.

Getting a little messy over here.

First of all there are those weird leaves that some people have suggested might be Utricularia tricolor. Secondly, the peat is all pushed up and furrowed. I don't really know why. Maybe I have earthworms in here? I don't know where they would have come from. The plants look pretty healthy anyway.

Finally, my Utricularia graminifolia is growing in again after I traded a couple chunks away.

Sort of growing in. I should experiment with different methods with this plant.

I had this growing in a windowsill earlier, and I feel like it was going a bit faster then. It's under lights right now. I'll leave it for a couple more months and see if it really wants that filtered sunlight instead. I've read that natural light is important to get it to bloom. Who knows.

Utrics are weird.

Cultivation Guides: Plant Trading

 This is part of a series of posts describing various aspects of cultivation, which will hopefully be useful to new growers trying to solve the challenges of growing carnivores, and experienced growers who are always looking to improve their collection. The full series can be read here, or by topic on the Series page.

Trading is an essential part of the carnivorous plant hobby. There are only a handful (maybe a dozen) sundew species/cultivars that are consistently available to buy anywhere (online or at nurseries). Nepenthes and Sarracenia are a bit easier to find, if significantly more expensive. Pinguicula are difficult and Utricularia extremely difficult to find for sale, outside of one of two beginner varieties.

So basically once you start trying to expand your collection you're going to have to start trading. At first it can be intimidating – beginners don't have much trading stock, shipping plants bare root seems risky, and the plants you receive in the mail usually look all ratty. Luckily, it's much easier than it seems.

I just completed a trade with a poster on Terra Forums who was initially looking for some Utricularia graminifolia (I've had a pot for a while, though I haven't posted much about it). In order to make everything worthwhile, we wound up with me sending some U. graminifolia, Drosera prolifera, Drosera filiformis Florida Red, and Drosera capensis 'Albino' and receiving Drosera affinis, Pinguicula 1717, Drosera capensis Bainskloof leaf cuttings, and seeds of Drosera sessilifolia and Drosera burmannii Giant Red (Hann River, Kimberley, WA, Australia). This was a very exciting trade for me, since I've been looking for D. capensis Bainskloof and D. sessilifolia for some time.

First up, sending plants. Sundews should be shipped bare root, with as much media rinsed off the roots as possible (this helps prevent accidentally spreading weeds or pests). These should then be wrapped in a portion of wet long-fiber sphagnum, and wrapped again in a damp paper towel. This can be placed in a plastic baggie. See below

D. prolifera plantlet, off to a new home.

D. capensis 'Albino' is the largest plant I shipped today.

Once again, D. filiformis Florida Red proves to be popular trading material.

For terrestrial Utricularia it's a little different. In their case, just dig out a plug of plants and media from your pot, and wrap it in a damp paper towel to hold it together. Then, into the baggie.

This is about the size of the plug of U. graminifolia that I started with.

All wrapped up safe.

Make sure to label all your plants clearly with as much information as possible. Species, cultivar, location data, etc. are all important pieces of information for the future owner. Once you've done that, it's time to pack up and ship.

I use the USPS small flat-rate Priority mail boxes.

Non-flat rate boxes can be affordable, but they're less predictable.

The boxes themselves are free, and shipping is only $5.80 for guaranteed 3-day delivery. That's about the sweet spot for shipping plants – anything quicker is exorbitantly expensive, and going cheaper puts the plants at risk with long shipping times. I find I can usually fit 3-4 smaller-sized plants in one box. If I were shipping mature specimens of larger species I'd have to use a different container.

I like to cushion my boxes with dry paper towels if I don't have other packing materials.

It's always best to ship at the beginning of the week, so that plants don't sit around in a post office over the weekend. Also keep the temperatures in mind – plants can be lost to freezing or baking hot weather on the receiving party's end.

When you receive plants in the mail, it's important to pot them up right away. They're probably stressed out from shipping, and getting them settled in quickly will make a big difference in how quickly they bounce back. It's good to have some media prepared in advance.

Looking forward to seeing this D. affinis get bigger.

This media has a lot of perlite in it for these pings.

One thing that I've come to find really helps my plants recover from any stressful situation, be it shipping or repotting or whatever, is much higher humidity. Therefore I now put a plastic baggie over the pots of my new acquisitions. This is also useful as insurance in case the plants you receive were accustomed to much higher humidity than your setup provides – the humidity tent allows them to be hardened off slowly, rather than potentially shocked to death.

I really like using humidity tents.

Since I received 2 leaf cuttings of D. capensis Bainskloof I decided to start one in water, and one on the media. This provides a bit of insurance in case one technique fails utterly.

I've not had much success with the water-float method and D. capensis previously, but maybe this time will be different.

My fingers are seriously crossed for this leaf cutting.

Finally, shipping seeds. Sundew seeds are tiny, sometimes hilariously tiny, which means shipping them safely can be a challenge. My personal favorite method is to make seed packets out of parchment paper, and envelopes out of printer paper. That way there is no tape or glue to catch the seeds, and the tension of multiple folds keeps the seeds well-contained. The fellow I traded with used pieces of rolled and then folded paper and tape that actually worked pretty well, but I still think the above method is the best I've seen.

Super pumped to be growing D. sessilifolia. Ever since I learned about its relationship with D. burmannii I've wanted some.

This is a different locality than my D. burmannii Humpty Doo, but I suspect it will look fairly similar.

Finally, remember to label your plants! Eventually you're going to reach a point where you no longer remember what's in each pot. Labeling will help you stay organized and make it much easier to trade in the future (nobody wants an unidentifiable mystery plant).

Happy trading.
