Most of the Yamamoto-type dendrobiums bloom twice yearly for me. They are not full and massive like the ones in the Yamamoto website, but I like the airy appearance they make for me, better. Which is a good thing, since there's much chance to grow them like the published photos. I give them high nitrogen orchid food when new growth is appearing, and low nitrogen after that. I keep them outside in the summer to early fall, and in a south facing window in the winter. These are very rewarding for me. The fragrance is very faint.
