Cleome spinosa Queen Series or ‘Spider Flowers’ are surprisingly not widely grown, a tall growing annual to 5ft with large 6” wide heads of spidery white, pink or violet flowers. Pinch out the main stem at 12” tall to encourage side shoots for more flowers. Each flower head continues to grow over many months gradually getting longer. If you have not attempted this plant before it makes a lovely display when mass grouped. For a shorter variety to 3ft, choose the F1 hybrid Sparkler series.
