I would be interested if any one can tell me more about this plant as I have been growing a plant that matches it,s description,although I cannot be sure of it's genus, the plants were grown form seed, acquired as a prize from a quiz competition in Fuerteventura. I have for the last 6 years nurtured three seeds, now some 8 feet tall in my conservatory, in a container. A question I need answering is should I separate and re-pot or leave them alone as they do not show any signs of distress (pot size round 18 x 18inches).
