Hi Susan: I can't find a lot of information on the individual Bomareas. B. acutifolia From Mexico and Costa Rica, this species is probably not as hardy as the others. The outer petals are deep red, the inner ones clear yellow deepening to orange-red without any spotting. The anthers are deep blue. Very vigorous, it grows to 15ft. B. patacoensis From Colombia and Peru. The outer petals are scarlet with inner petals that open yellow and turn to deep red spotted heavily with darker red. Grows 8-12ft. B. petraea Source unknown. A smaller Bomarea, only growing to about four feet tall producing dense clusters of orange-red flowers, the inner petals marked with maroon. The three species I would have to know which ones they were to provide data - I do have some collection data for them. I will try to find where B. petraea comes from. Diana
