Where to plant Buddleja

Buddleja like moist but well drained soil and plenty of sun. Smaller varieties will be 1m to 1.5m tall and can be grown in large patio pots. Larger forms can grow to over 4m tall and 4m wide when fully grown, Size can be managed by pruning if your plants are getting too big. There are some frost tender forms and these can be grown in the colder areas of the UK in a pot that can be moved to a frost free area in winter or in a conservatory.

How to care for this plant?

Buddlejas benefit from hard pruning in spring to remove tall growth from the previous year. Buddleja will flower on the new growth that follows. Pot grown plants given a high potash liquid feed will produce more flowers. By removing old flowers the flowering season can be extended.
