It is hardy to zone 5 and is not frost tender. It is in flower from Mar to April, and the seeds ripen in May. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Bees.The plant is not self-fertile.
