I guess it depends on your space limits. *My all time favorite is D. pulchella x ericksoniae. *It is *the largest *growing pygmy in my collection, and is very undemanding. *4 gemmae will *grow to fill a 4 inch pot! * Also good is D. paleacea ssp. roseana and Drosera nitidula x D. occidentalis. *They are all different looking, easy and beautiful.
