Euphorbia x martinii 'Ascot Rainbow'....the flowering shoots are initiating already

They do bloom early.

Over the past twenty years or so I have developed a fondness, not an obsession!, with the hardy garden Euphorbias: E. martinii,wulfenii, dulcis, griffithi, amygdaloides and the rest. They love the sandy soil here, tolerate the cold of winter, the heat and humidity of summer, and never need supplemental watering. I always worry that there's some point at which vibrant variegation veers shamelessly into blatant vulgarity. Not in my garden. Hey, I grow Canna 'Pretoria' next to this and sometimes bed orange Hibiscus rosa-sinensis with them.
