My guess is that it's one of the Rhodophialas, which should be blooming right about now. R. advena's flowers are more scarlet-orange than those of bifida, which is the most commonly seen species, so that might be a good guess. It has lots of color varieties, so it's a possibility. I think it's a little late for H. puniceum to be blooming now, and I think that's a bit larger, although I haven't seen one "in person" in a while. I know that Hippaestrum aulicum, for instance, can bloom in late summer, as can the hybrid 'San Antonio Rose', but they are larger than the flowers you describe. It's always exciting to get something like that and then "sleuth" it out!

You might try asking at the link below...A pic sure would help too, if you could provide one.

The Name That Plant Forum might also be able to help, if you haven't already tried them.

Oh, cool! I always wondered how you all do that! (John McCain has my fullest sympathies on being caught being computer illiterate.:)

Just a note: It is a total mistake to think that Hippeastrum do not bloom in the fall. While my H. puniceum bloom in the spring my H. striatum bloom in the fall as do my blossfeldiae x striatum so you may have a fall blooming Hipp....there are many of them :o) Dan

Thanks, Dan. I guess more than anything, time will tell.
