One of my AV's blooming today is the lovely Russian, RS Rosinka. What I think is very interesting is in my summer heat, the flowers are quite purple with a trace of white edging as shown in the first photo. The flowers are also 2.25 inches wide. Where as in the second photo from back in March when it was much cooler, the flowers were every bit of 3 inches across and nearly entirely white. I love how temperature fluctuation can make such a huge difference on my AV's and streptocarpus.
