Favourite Growing Conditions
Enjoys full sun and a sheltered position. Soil should be well-drained but not over rich in manure.
Normally raised from hard-wood cutting in open ground in winter or cuttings from this year’s new growth in early autumn. Seeds can be sown but are difficult to germinate.
Young plants should be given a light pruning in the first winter. Heavier pruning is needed in subsequent winters to keep plant from getting straggly.
Leaves can be taken after a couple of years.
Leaves can be used fresh or dried or frozen.
