I like Cyms, but I needed to stick with smaller more compact plants. So I tried some of the Chinese Cyms. They don't require as much light and will bloom even with warmer temps - in other words no cold spell needed to initiate blooming. Many have variegated leaves. I have 2 with yellow variegation and 2 with red variegation (fades to green as the leaves age). Flower are a bit more delicate looking, but with similar substance to the standard Cyms. Plants stay under about 10"
Here is a pic from last year of Cym. ensifolium 'Shi Chang Hong'. It's in spike again and should bloom next spring.
