Tender subshrubby perennial with long arching stems and narrow dark green leaves. Insignificant green and white flowers, but produced curious, large inflated seed capsules that are transluscent light green and covered with soft spines.
Very similar to G. fruticosa, but with slightly sparser, larger flowers.
Well-drained soil in full sun or part shade. Needs a warm location.
Very popular for flower arranging.
