Perfectly suited to Adelaide’s Mediterranean climate, it grows quickly to cover fences, pergolas and trellises, filling courtyards and alfresco areas with an unforgettable sweet perfume. Vigorous, reliable and easy to grow, it brings seasonal drama and scent at a time of year when many gardens are still waking up.
