I have two D. mads. Both have flower spikes with plenty of buds, though one is much further along. However, I have yet to see a single flower. Instead, they seem to stop at the bud stage. I can see the pink/magenta of flower petals at the tip of the new buds and old with the those of the older having the withered look. They never got beyond this stage. Despite this, at least one of the oldest buds shows distinct signs of swelling/seedpod formation. This being my first try with D. mad, I have no idea how normal this is.
