Tuberous drosera question

Recommended Posts

Hi all!

I start growing Drosera subhirtella and zigzagia 3 years ago and last year I got an incredible amount of flowers from both plants (and also seeds from the crossing).

This year D. subhirtella didn't come back and zigzagia is smaller and without flowers. I digged out the subhirtella tubers and they are huge and healty without any sign of growth or illness.

Is this happened to somebody else? Does tuberous drosera take a one year long nap after a season of exceptional growth and flowering?

I had a macrantha ssp macrantha do this once. I thought I had lost the plants and dug up the potting mix to reuse and found a fat heathly tuber. Replanted and the plant is still with me. This happen a few years ago.

Hi Vale,

I experienced the season without growth mostly for plants which are somewhere in the adaption process from the southern to the northern hemisphere. Sometimes, the tubers also just produce a new tuber without any visible growth above the surface. This season, I had 3 forms doing this and I decided to store these tubers in ziplock bags to be able to check on them every once in a while.

Similarly to your D. zigzagia, a D. menziesii ssp. thysanosepala which has flowered for the past 2-3 seasons just reached about 5 cm in height this season, which is not much more than the one year old seedlings grown from seeds of this very plant.

Best regards

Dieter
