description:
Very large heads of double, lilac-blue flowers, opening from red-violet buds.

cultivation:
All lilacs are hungry and thirsty plants and should therefore be positioned with due consideration. They benefit from generous additional feeding. Can be pruned hard to rejuvenate in mid-winter. Remove unwanted suckers as needed. Some flowering may be lost after pruning as flowers are produced on two year old wood.

propagation:
From greenwood cuttings, by layering or grafting.

other notes:
Raised in France, about 1886.
