Plants of Scaevola ‘Blue Wonder’ should be safe in a frost-free greenhouse for the winter as it is a half-hardy shrub. Trim back the growths so that the plant is manageable and water only sparingly when temperatures are low.

Plants can be propagated from cutting of young, firm side shoots taken in August. Root them in gritty compost and keep them warm, under glass, until they are rooted. Plants can also be raised from seed sown in a warm greenhouse in early spring.
