I don't have many, but my fave is the D. Filiformis California Sunset. It is nice and tall, almost 1 foot. Grows a nice clump. Lots of flowers and seeds. And pretty hardy. It doesn't have a lot of color, but it is a very nice looking plant and very easy to grow. (thankfully)
I love all drosera and it is what I mainly grow. The favorites in my collection are pygmies, d. paradoxa, d. graminifolia, and d. multifida 'extrema'. But I really love them all. And for the cape sundew 'dormancy' issue, the leaves will die away, but the plant will return. It is not a real dormancy.
