Have posted this elsewhere, but wanted to post here, too.
Pardon my long silence. Have been really busy for a very long time. But, I have interesting news!
After 14 years, my N. villosa is producing an inflorescence! Although the raceme has yet to fully develop, my initial guess is that this is a male plant. Therefore, I would like to hear from other growers around the world who may have interesting females available with which to make new hybrids. I would like half of any seeds produced with villosa pollen.
Below are a couple of images, taken today. It is evident that it will be some time yet before the flowers are mature. But, I am hoping that within a month or so pollen will be available. The inflorescence has grown relatively quickly, having doubled in size in about two weeks.
Of particular note is the hirsute nature of the inflorescence. It is covered in a dense, auburn indumentum, the like of which I have never seen on any other species.
