Which Drosera is this?

This is an older picture and the plants in here have long been separated into their own separate pots. But I'm curious to know what kind of sundew is the one in the far upper right corner. Is it a D.spatulata? The larger one I'm guessing is a D.capensis, right?

Also I would like to propagate more of the smaller one, since I'm curiously fond of it. I've heard a leaf cutting will do, will putting a few cuttings in wet sphagnum stimulate rooting?

Yep, the larger one with the elongated lamina is D. capensis, the smaller one is either D. spatulata or D. tokaiensis, which is a fertile species/hybrid between spatulata and rotundifolia.

I would say D. spatulata

Like the others said, it looks like a spatulata.
To propagate it, either let it flower (it will produce hundreds of seeds by itself) or take a leaf cutting.

I personally prefer the water floating method for leaf cuttings. What you do is cleanly cut off a leaf and place it, sticky side up, in a jar of distilled water. It doesn't matter if its submerged, but should float. I find that i get more plants this way than just putting it in sphagnum.

For leaf cuttings, little plantlets pop out of the leaf and its the actual plantlets that grow roots.

This is what you should get in a few weeks (image from growsundews.com)

Oh, how cool! Are frequent water changes recommended if I use the float method?

From personal experience, its not really necessary to change it too often (if at all). Once a week should be fine. Of course, if the water turns brown or cloudy then changing the water would be beneficial.

I think that changing the water every week or so will increase the sprouting rates but again I'm not sure - it seems common sense-ish to do so. Put the jar under bright lighting (morning sun is great).

from my limited experience i find root cuttings a faster way to get a large plant,just cut off a healthy root 1 or 2 inches long and just cover in live sphagnum,wet of course,i find this method quicker
