True Drosera dielsiana is very rare in the US. Most of what's circulated as "dielsiana" is actually natalensis, and the species are very closely related to each other, further adding to the confusion. Pictures of the plant I've seen in the wild have very round lamina, and these seedlings from Alexander Dietrick look just like them. Plants are only a few months old from seed, and rather slow. I've been feeding them often with small bits of rehydrated bloodworms, and so far they seem to be appreciating that.
