Description

The award-winning Buddleja ‘Black Knight’ is one of the most popular butterfly bushes, producing fragrant summer flowers in a gorgeous shade of deep purple in long, outstretched panicles. These blooms are accompanied by grey-green, lance-shaped foliage. As its nickname suggests, this easy-to-grow, low-maintenance shrub is much loved by butterflies, and a great option for bringing more pollinators into the garden.

A full sun position is preferred, though Buddleja ‘Black Knight’ will tolerate some partial shade as well. Drought-tolerant once established, in 20 years you can expect an approx. height and spread of 3 x 3 metres.

Planting Steps

1Preparation

Pot-grown plants can be planted at any time of year, whereas bare roots need to be planted between November and March.
Clear weeds and grass within a metre of the planting hole.
Dig a hole as deep as the root mass and twice as wide.
To help your plant establish more effectively, sprinkle Rootgrow in the hole.

2Planting

Gently loosen the roots and place into the planting hole.
Ensure the top of the plant's compost is flush with the level of the surrounding soil and the graft union or collar of the tree is above ground level.
Mix 50% of the original soil with 50% compost.
Fill in the hole, firming the soil gently.

3Last Steps

Water generously around the base of the plant.
If you are planting either a single stem tree or mature standard tree, we recommend adding a staking kit and rabbit guard.

Aftercare Advice

Trees and shrubs require a good watering regime for a couple of years whilst they establish. Water well and regularly through spring and summer, increasing in hot or dry weather. If planting in autumn, you may only need to water a little. It is advisable to keep the area free of competing weeds and grass during this period.
