Speaking of Canary Islands endemics, my Dracunculus canariensis grows well under a 400W Agrosun lamp each fall-winter in a gritty open mix. It now has 2, 2 foot tall 5-6 leafed shoots as in previous years but so far has never bloomed. This year I'm trying more phosphate fertilizer. Bonaventure Magrys Cliffwood Beach, NJ USA
