Beautiful Jim! Wish I had room for a Poinciana. Our Jacarandas are not blooming yet.
What do you need to know about the Epiphyllum? That one is in a 24' basket and has flowers about 8" across. The flowers only last 2 or 3 days, but are well worth the wait. They play well with orchids! Here is a link for more culture info
