A very ornamental plant, it is hardy to about -20°c. The plants flower best in years that follow hot summers. The nuts/seed are said to taste like pistachios, the seeds are eaten by children in Germany.
Tolerant of a wide range of soils so long as they are not too dry, it prefers a rich loamy soil in full sun or semi-shade. Prefers a neutral to acid soil but tolerates some alkalinity.
Can be very slow to germinate, sometimes taking 18 months or more. Should be sown as early in the year as possible and given cold stratification - it might not germinate until spring of the following year. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the greenhouse for their first winter. Plant them out early the following summer.
Seed - raw. Said to taste like pistachios, the seeds are eaten by children in Germany.
