I got Happy Returns from a big box store in 2010 and put it in two spots in the front of my house where I needed a short plant. Happy Returns has multiplied very well, but I don't get much rebloom, which makes me wonder if (and probably so) my plant was a result of tissue culturing. Can a true Happy Returns plant even be found anymore?
The question was asked about it being nocturnal and my plant does not show evidence of being nocturnal. I've never seen it trying to open the night before. This picture still has spent blooms on it from the days before. It does appear to have a slight trumpet shape to it. It it sitting next to Siloam Double Classic (registered at 16" height), so the height is right at about 20".
6/10/2014 - this picture was taken around 4:30pm and based on other pictures it had rained, so the petals are looking thin and worn.
8/16/23 - I did get two polys on the same day this year on one of the few rebloom scapes. The clump is looking worn and tired and is almost done except for a few more blooms on this lone scape.
