Buddleja davidii Black Knight are versatile and easy to grow shrubs, they are deciduous and so plants delivered in Winter will have lost their leaves, but fresh new ones will appear in Spring. Buddleja shrubs are renowned colonising plants, self-seeded plants are often seen on railway embankments and even growing out of walls but don’t let that put you off. These fast growing shrubs make a great addition to borders and wildlife gardens where there prolific flower heads will be a magnet for many species of beneficial insects, especially butterflies.
Buddleja Black Knight grows best in full sun or partial shade and in any soil that doesn’t become waterlogged in winter. For best results, the shrubs should be hard pruned in March each year, right back to three or four buds. This will keep the shrubs bushy and attractive in shape and a more manageable size while encouraging the maximum number of flowers each season.
