Drosera lowrieiDrosera lowriei can reach up to 4 cm in diameter (typical form) or 5-7 cm (giant form) respectively. Flowers are produced on scapes up to 1.5 cm (typical) or 3 cm (giant form) long, with up to 8 scapes produced from the center of the rosette in the typical form and up to 50 scapes in the giant form.
The tubers are yellowish to light pink and covered by dark papery sheaths from previous year's tubers.
D. lowriei is quite hesitant to produce additional tubers. However, I received one tuber of the giant form which produces at least one extra tuber per season. After several growing seasons tubers of other plants increased in size reaching currently about 2 cm in diameter whereas this more readily dividing plant stays at the size of about 1 cm. Nevertheless, the plants look all the same in terms of size and flowers. The large form can be distinguished from Drosera zonaria by the leave shape and the abundance of flowers. Drosera zonaria rarely flowers, and if it does, it produces a single flower stalk with up to 8 flowers.
The typical form can be pollinated as long as pollen from a second clone is available. However, it seems to be nearly impossible to pollinate the giant form flowers.
"The giant D. lowriei appears to be sterile and a genetic screw up. It was originally discovered growing with an all green form and a green form with red margins and scapes as well as reddish forms that were closer to but not quite the type for D. lowriei. It appears the giant D. lowriei maybe a disfunctional hybrid between these different colour groups at this location." (Allen Lowrie, personal communication)
type formThe tubers on the second picture have the roots still attached.
yellow plant formOne of the more recent additions to my collection. So far, the plants certainly lack the reddish colour in the tentacles, but the overall appearance is more greenish than yellow. Anyway, it is a beautiful variation.
giant formIf you check carefully the first picture, you will see that one plant produced quite a few small extra tubers. So far, I only observed that for plants which are all offspring of a single tuber I some years ago. Usually, the plants do not produce any extra tubers.
