Identify my alternate-leaved butterfly-bush

A shrub measuring 2 to 5 m, with velvety stems, opposite, greyish green, lanceolate leaves, sizing 10 to 30 cm long. Flowering is in summer, with dense panicles, erect, of very fragrant purple flowers.

Plant my alternate-leaved butterfly-bush

Plant from the end of autumn to the beginning of spring, in the sun, in all types of soil except very rich earth. Don't bury the base of the plant too deeply. Tamp down the earth around the roots, form a shallow basin and water until no more can be absorbed.

Mulch my alternate-leaved butterfly-bush

Mulch in November each year to protect the soil — especially for the first few years — and limit weeding.

Prune my alternate-leaved butterfly-bush

In March, every year, prune all the branches, just flush with the ground; this operation is called coppicing, it forces the plant to re-emit stems from its roots. If you notice that your shrub is weakened by competition from taller plants, trim it every other year.

Water my alternate-leaved butterfly-bush

Water in the first weeks if the weather is dry - and soon it will not be needed anymore
