Coming from Sth America, S. biserrata likes a sunny well protected position as it is frost tender. Grow this shrubby plant in the middle or the back of the bed. Lovely when in flower, the bright blue/ purple flowers showing well with other white or pink flowering plants near by.
This plant grows well under large deciduous trees in dappled shade or with other similar shrubs. They enjoy regular watering during the dry, hot summer months. This can become dormant in cold areas, but can remain green and flower during winter in warmer areas.
When dormant in the colder months, cut down old stems, clean up the base and mulch well to keep the crown warm. Remember to feed in spring when the new shoots appear.
Propagated :easily from tip cuttings taken in spring and summer.
