Cleome hassleriana ‘Rose Queen’. This is a half hardy annual capable of flowering for months. Flowering will end when the first frosts come. However if you have a few of these in your garden they will produce many seeds that will disperse. Some will overwinter and grow next year. In fact stratifying seeds in the fridge before sowing in spring is how we get the best germination. This one grew from last year’s seed.
