I bought this at my local nursery, only to realize once I got it home that it had no ID on it. It has light/medium green leaves, pale new stems, quite pendulous branches. Sepals are white, but sometimes get a pink blush on them. Huge blossoms, but sepals are always 'flaccid' (you can't pop them, there isn't enough stiffness to them) and they sometimes fail to open properly. Corollas are a cerise? / deep pink, and sometimes streaked in a paler color. I water it every few days (it's in a 3 gallon pot), and never quite dries out, but it's not soggy all the time either.
I can't find it online, but I also don't really know how to search for it, either. Anybody have any ideas on what it is, or can direct me to a site that catalogs them (and tell me how to search other than going through each and every photo!)
