I have two of them that bloomed this year for the first time. They are really cool, but I never saw any butterfly or bee activity. Something ruffled them up one night or early morning though. I came out in the morning and I could tell something had been digging through the fat flower heads, and something had also knocked off lots of grapefruit blossoms.

Grapefruit trees are the sweetest most heavenly fragrance, better than the other citrus I have thus far smelled. Budha's hand is good too, but not as powerful as the grapefruit. My S. puniceus were fragrant, but it was subtle, not sweet or anything, just sort of polleny, I guess.

I keep mine in containers, but they grow in the ground in Houston. It seems like I saw bumble bees on them at the nursery right before I bought them. They're definetly cool plants, but they were pretty much bust as far as a nectar source from what I saw this year.

Probably just as well; apparently they are highly poisonous in all parts and times of year. :( At least to mammals, don't know about bflies and birds and bees....
