Cultivation Details
Hibiscus laevis is a very cold-hardy plant, able to tolerate temperatures down to around -30°c when fully dormant[1]. Best grown in organically rich, medium to wet soils in full sun. Tolerates some light shade, but full sun produces best flowering[1].
Propagation
Seed - sow early spring in a warm greenhouse. Germination is usually fairly rapid and no special pretreatment is needed, although germination will be faster if the seed is abraded or soaked prior to sowing[2]. Prick out the seedlings into individual pots when they are large enough to handle. If growing them as annuals, plant them out into their permanent positions in early summer and protect them with a frame or cloche until they are growing away well.
