) I say they rival D. capensis!
....that means that when it is done flowering it dies. It starts growing smaller leaves when half of the flowers on the stalk are done blooming. The leaves grow smaller and smaller and look undeveloped, it means that the plant is dying. When it disappears from the surface it still pumps nutrients from dying roots to the stalk to finish ripening of the seeds...then the roots die and the plant is gone completely. It doesnt come back from roots anymore. Leaf pullings are a no-go with burmanii. It comes back from hundreds of seeds as a new colony of D. burmanii. You can delay the death of the plant by cutting of the flower stalk but then you get no seeds and when it flowers later the seeds are less and less viable. I had burmanii for 3 years longest cutting the flowers constantly, but seeds are a very easy to spread the number of plants in your collection
