Hi guys. Many informations can be found on internet about these 2 species, but nothing is very clear. Many growers think they are the same specie, and many conflictual reports has been made over the past years. So i wanted to try both species. Each one came from very different but trustable well known growers. Drosera delsiana Drosera delsiana by dals009, on Flickr Drosera "pretty rosette" Drosera "pretty rosette" by dals009, on Flickr And to compare, a drosera spatulata Drosera spatulata by dals009, on Flickr All the plants are adults, flowering size. And i grow them for a while. As you can see in the pictures, delsiana is smaller, and the leaves are different in shape, and in color. The flower stalks are very different also. The flowers colors look the same, but the size and color is slightly different. Also, i found that delsiana need more RH%. Drosera "pretty rosette" by dals009, on Flickr Drosera delsiana by dals009, on Flickr Hope this thread will help for future reference. Cheers Francois

What you call 'pretty rosette' looks very similar to what I'm growing as dielsiana. Your dielsiana has a flatter rosette whereas mine is slightly conical - similar to your 'pretty rosette'. Mine are from shoggoths, if he's growing both it'd be interesting to see his forms. FWIW, I have some Drosera sp. seeds sprouting from Silverhill but they didn't say if they were 'floating' or 'pretty rosette'.

I see.
However, the source where i got the plant is not a nursery where a misstake can happen. Its a private and very trustable grower. Im sure at 99% my plants are well labeled.
But i cannot said 100%..

I must say I can't tell members of this "complex" apart.

I must say I can't tell members of this "complex" apart. And if you two cannot agree, good luck for the rest of us! Here's some photos of dielsiana and Drosera 'sp' seedlings. BTW, if anyone knows whether the Silverhill Drosera 'sp' seed are "floating", "pretty rosette" or something different please let me know. Both mature dielsiana, the smaller has a 'flatter' growth habit. The larger one is closer to Maiden's Drosera 'sp': Detail of large dielsiana: And Drosera 'sp' seedlings about 5 months old. These leaves seem more spoon shaped (i.e. closer to spathulata oir tokaiensis) but these plants are still very young and I'm learning their growth habits: Endless hours of viewing pleasure! And debate...

Thanks for sharing your photo Your delsiana look like a d."pretty rosette" to me. Try to take a zoomed picture of the flower(your delsiana). I will do the same for my pretty rosette n delsiana in the next few days. We will compare Like you said, i think theses species names was very conflictual. This kind of mixedup happen when many field collectors are rivals with no collaboration. Anyway, i really enjoy these mini rosetted droseras:)

"Anyway, I really enjoy these mini rosetted droseras"
I agree. To me these are the ideal newbie CP's. Attractive & easy to grow from seed/cutting, last for years with no particular effort.

Syble gave me one labelled Drosera sp. "South Africa" a few years ago. It looked like "Pretty Rosette". Lime green stumpy leaves with a pink blush on the tentacles. Flowered and self-seeded like a weed.
Some of the experts say that there are no true D. dielsiana in cultivation, anyway. They're all D. natalensis.

Here are mine : dielsiana P1090291 par Shoggoths, sur Flickr sp "Pretty Rosette" P1090292 par Shoggoths, sur Flickr In the same growing conditions, dielsiana is 1/4 inches bigger than PR. The big difference for is that dielsiana bloom a lot is a real weed. My number of PR stay stable. I have a microscope on the way. If I can get seeds of both, I'll try to take pics for comparison.

Enfin, D. diesiana flower details (not enough coffee yet...): With D. capensis 'narrow leaf' flowers. These capensis split - perfect timing to catch them both open together: A size reference: D. aliciae flower stalk by comparison - similar to your 'pretty rosette' flowers! This scape is 10" tall, the budding portion is 1" now. This plant was also courtesy of shoggoths. I expect it'll be as tall as the dielsiana scapes, around 14": Very mobile leaves, this one folded overnight around a large fruitfly: This species is also quite hardy but I found that it'll do okay in medium light but needs high light to thrive. Bumblebee tools in the background, I've tried crossing capensis 'red' with dielsiana - both ways.

Soooo, I finally took some time to play with my usb microscope. Here are my seeds pictures. Pretty bad quality but I'm really not well installed yet. It seems that what have been given me as dielsiana is in fact natalensis. It's the second time I look at those seeds and I'm pretty sure I had some round seeds in the past so perhaps I have both species in the same pot ... I'll have to check all flower stalk one by one then ... sp. Pretty rosette PrettyR par Shoggoths, sur Flickr PrettyR 2 par Shoggoths, sur Flickr Natalensis, formerly identified as dielsiana natalensis par Shoggoths, sur Flickr natalensis 2 par Shoggoths, sur Flickr At least, they look different. Also, I'm pretty sure none of those are tokaiensis. My tokaiensis is flowering now so I'll take some picture of those seeds too. [url= [/img][/url] #5 - dielsiana #6 - natalensis
