Buddleia Davidii “Black Knight” is a deciduous shrub also known as the butterfly bush because it is one of the best shrubs to attract butterflies to your garden.

A tough easy to grow shrub that once established is drought and frost hardy. It makes a lovely feature at the back of the garden, screening plant or informal hedge.

: Cultivate soil before planting. Dig hole twice the width of the container. Remove plant from container and place into the hole so that soil level is the same as the surrounding ground. Fill hole firmly and water in even if the soil is moist.

Care: Always ensure regular watering is provided for your new plants. The plants may need watering for around 12 weeks or until they are established depending on time of year and weather conditions once planted. 

Good mulching will assist to reduce weeds and maintain moisture levels. Maintain fresh growth, shape and promote dense habit by pruning after main flowering time. Feed in early Spring with a good all-purpose fertiliser.


Using tubestock is a great advantage for planting in your garden as they will establish quickly with the appropriate care.

Plants are supplied as tubestock in 42mm wide pots. Your plant will be established in its pot and ready to plant out.
