Where can I buy seeds to grow loofahs and will they grow in the Adelaide Hills?
(Peggy Mitchell, Charleston, South Australia) Luffa cylindrica seeds are available from www.greenharvest.com.au. It’s an annual vine for warm-to-tropical climates, and is killed off by frost. Your challenge will be having enough warm summer days to develop the fruit. A warm, sheltered microclimate will help, such as on a north-facing brick wall.
