Aptenia loves full sun but Columnea are Gesneriads (same family as African Violets, Streptocarpus etc.) and don't like direct sun at all. 'Frosty Hills' has such pretty foliage and from this photo the blooms are gorgeous against those variegated leaves:

I just submitted a proposal to add cultivar 'Frosty Hills' to the database; I hope once it's approved you will add a photo of your plant.
