Anyone grow Drosera riparia?

I got some Drosera riparia seeds from the seed bank and (luckily) two germinated :D. They are adults now and producing their own seed. Here are some pictures below. Anyone else grow this species? Also, just confirming, is this truly Drosera riparia?
Thanks in advance!

Those look more like Drosera communis.
D. riparaia should have a longer leaf, similar to D. latifolia.

The seeds were marked as D. riparia when donated.
I don't remember who donated them.
I'll have to go back and search my records.

You do have to expect things like this now and then.
Sorry 'bout that.

Thanks.

Another grower said those resemble Drosera capillaris.
Did you plant any seed of that species?

Yep unfortunately not riparia. I'll have to send some riparia seeds in when my plants flower.

These aren't D. riparia (more upright, longer leaves), and absolutely not D. communis.
Not intending to be harsh, it's just that D. communis already has a problem with bad IDs to the point where a big chunk of the cultivated photos you find aren't actually that species.
D. capillaris is a good bet.

Hi there. Piggy backing on your d.riparia conversation. What's the best care for them? Just got them about 3 weeks ago and they are not responding like my other drosera's do. Don't know how to send a picture from here, sorry.

Yeah riparia can be finicky, they can take a really long time to settle in. Their growth can be pretty paradoxical, with plants that otherwise look very scraggly and in bad shape sending up multiple thick flower stalks and setting copious amounts of seed. I have yet to grow a specimen that I am happy with, and yet I think all of my plants are either flowering or just finished flowering right now :lol: I also think that they just have a natural tendency to hold fewer leaves than their relatives like latifolia or graomogolensis.
I've found that they actually do better in a peat based mix rather than a lfs based one, at least in my experience. High light is a must, and high humidity doesn't hurt either. Basically grow it like any other SA dew but be ready to cut a lot of flower stalks if you want a nice specimen...

SA dews do fine in peat.
I hate to give my sphag to plants that don't ABSOLUTELY need it.
Heck, I grow my Andromeda in peat, as with my Adelae, even though people whine about sphagnum. Same for some nepenthes and even helis. The downside is you need to repot once stuff decomposes.
Just IME.
