This hardy perennial will grow in any soil but prefers a well drained soil in almost any aspect, including shade.
The roots should be protected from direct sunlight.
Mulching annually in March will offer this protection, and also conserve moisture.
The mid-green leaves are oblong and clasp the stems.
White flowers up to 25mm long are produced in June in clusters of two to five.
It grows to around 1 metre high and they should be planted out between September and March (when conditions allow) approx 500mm apart.
Cut plants down to ground level in November.
Divide, and replant in October to March when conditions allow.
Sow seeds when fresh, in pots/trays of J.Innes seed compost (or similar) in late summer and place in a cold frame to germinate.
Germination can take up to eighteen months, prick out seedlings when large enough to handle into 70-90mm pots of JiNo1 (or similar) and grow on for a couple of years then plant out into flowering position in October.
