I have had a Flordia Sieboldii for several years that has lived in a container since I reside at the limit of its cold tolerance. Having spent the winter in a cool basement garage, the plant had gone fairly dormant as usual. A watering in February woke it up and it put out new growth. When it started froming buds we moved it upstairs and gave it light and water. Spring came early and warm and the container was placed on our deck. The first bloom looked normal as it opened with white petals. Then this bloom shriveled up without fully developing and all the subsequent blooms have been purple as in the photo. Same plant. What happened? How can the plant abruptly change like that? Any insight would be greatly appreciated.
