I'm a Drosera, but I don't know what type...

After completely neglecting my indoor carnivores all summer (the outdoor garden was my focus), I'm now turning my attention indoors again.

First off, I have these unknown sundews. They seem to do well in indoor conditions, year-round, and don't need any dormancy (or at least I haven't given them any dormancy, and I've had them for 3 years or more.)

Can you ID what species of Drosera I have here? Are there any special growing conditions? It seems to have done fairly well over the past three years, but maybe I'm missing something?

-Don

Here's a few recent pix. The live sphagnum moss has grown very well, and the sundews have had a bit of a challenge to keep pace.

    Hello don555,

    Looks like a nice clump of Drosera anglica there. They can be found all over North America and even in Hawaii. The Hawaii version is a tropical and will not require dormancy, so you likely have that particular version of the plant.

    I was gonna go with D. intermedia, but a lot of these sundews really do look alike?

    Here is a picture of D. intermedia and anglica (CA x HA):

    D. anglica is on the right.

    Here's a clump of D. intermedia, for comparison:

    Thanks for the help. After searching around today, I managed to find some old seed packets from when I placed this order with ICPS (December 2004). There are two packets of D. intermdia, one from a Cuban variety and one from a Venezuelan variety, so that seems to fit. Neither need dormancy. It's possible that I bought some D. anglica and didn't keep the old package, but mine do look very similar to the D. intermedia pics posted by petiolaris, above. As noted, many sundews do seem to look a lot alike... now, can anyone tell me whether my clump is the Cuban or the Venuzuelan variety? (darn, how do I put in a winking eye here?)

    I agree with petoilaris,
    Drosera anglica has thinner leaves.

    petiolaris:

    Your D. anglica looks very different from the pictures I have seen in books and online. I never have had a chance to grow one yet, so I just have to go by pics unfortunately.

    ....and I go by whatever other hobbyists write on the baggies! Seriously, once in awhile something gets mislabeled and cultivars may look all alike or different. And pictures sometimes give a different story as well. Unless we do genetic mapping, we can only do educated guessing. But at least nothing else looks like a D. adelae!

    Yeah, I saw some pics that looked exactly like Drosera intermedia and they stated that they were Drosera anglica... strange. Now Wikipedia has a good pic that matches your D. anglica to a T.

    don555:

    The Drosera intermedia from Cuba only grows about an inch or so across while the North American version grows about twice as large. I have no information about the Venezuelan subspecies other than it also can be raised as a tropical like the Cuban one. Yours look to be a couple inches across...

    mutant hybrid, the biggest plant in that clump is 30 mm across, so that certainly fits with the Cuban variety. Guess that still doesn't differentiate it from the Venezuelan variety because we don't know its size, but I'm still very impressed with the partial ID!

    Maybe it's just me, but on a given plant of D. intermedia, the leaf shape is different. Some leaves have a spoon shape and some are more elongated.

    It could also be Drosera capilaris.

  • mutant_hybrid

    The Drosera capillaris I have grown looked more like Drosera spatulata to me. They grew overlapping leaves and about the same size as a D. spatulata, but with less reddening and wider petioles. At least the ones I had looked like that.

    The problem I had with the identification is the book I got the pic from only depicted the plant from the top, and a D. anglica from the top looks kind of like a D. intermedia in an old black and white photo. After looking at the written description and petiolarisi's pics, it is obvious the D. anglica is a much larger plant with longer trap surfaces and more upright petioles.

    I think petiolaris has positively IDed the ones depicted by don555 as D. intermedia and their size indicates that they probably are the Cuban variety since 30mm is the exact size the adult Cuban D. intermedias get. Since we are not sure about the Venezuelans, then at least they can both be raised as tropicals, so no harm done either way.

    You KNOW I'm gonna post a picture! D. capillaris:

    petiolaris:

    Those are the reddest D. capillaris I have ever seen. I had mine in a window with supplemental florescent light and they always stayed green. Mine also had wider, shorter petioles. I always had carpets of the tiny seedlings all around my other plants.

    Yet another indication of how similar those rosetted sundews look.

    I even contacted the company that cloned my D. spatulatas and they could not tell me what subspecies they were producing... interesting huh?

    Mine looked like the Alambama subspecies in this pic at the top of the page except no red color:

    Anyway, nice looking D. capillaris.

    That was the result of our recent move and having to put the collection on the porch, in full sun. That either reddened, fried & recovered, or just plain fried the plants to death. I must have thrown out 10 sundew species!
