The gemmae of pygmy droserae can grow to mature plants in 6 months under uncrowded, ideal conditions. Almost all of the gemmae I have sown in Dec.-Feb. have grown to mature, flowering plants. Fast growers include hybrids, pygmae, niditula ssp., pulchella, ericksoniae, occidentalis ssp. etc. I have found some pygmies like palacea ssp. trichocaulis to be slower growing than D.nitidula ssp. omissa x occidentalis ssp. occidentalis etc.
