I have a ton of D. burmannii from Humpty-doo and Hann River. Each plant, totaling over 25, is over an inch across, bright red and healthy, and sending up startlingly thick, robust flower stalks. I was prepared a month ago for a hailstorm of seed.
So far, from all the plants combined, I may have collected around six flowers that produced any seed. Most of the seed was shrunken and aborted. The rest of the flowers have produced nothing. *NOTHING*.
My nighttime temps dip into the sixties, and in deep winter into the high fifties. I suspect, that though my burmannii are huge and well-fed, that they aren't producing seed on account of cold temps, especially at night. I suspect also that the lack of seed production is why the flower stalks that they've sent up haven't had an effect on the health or vigor of the plants - as inert pieces of tissue, they have little energetic or nutritional expenditure.
I am frustrated that I have gotten little seed. But I am also curious: does anyone else notice that burmannii won't set seed in cooler temps, or at particular times of year?
Thanks all!
