My _Drosera pulchella X nitidula_ plants produce plantlets on their flower
scapes. Not every scape does this but the plants consistantly produce
plantlets on about one scape in ten....every year for the past five years.
I cannot link this with seasonal changes.
None of my other pygmy Drosera have exhibited this phenomenon.
Comments anybody?
