USDA Plant Hardiness Zone Map

Close

Butterfly bush likes well drained, average soil. They thrive in fairly dry conditions once established. Roots may perish in wet soil. Butterfly bushes are semi-evergreen in climates with mild winters. They may be cut back to the ground and will re-emerge from roots in their northernmost range, but will not reach the maximum size they do in warmer climes. It is advisable to cut back the shrubs in any case, since flowers are usually larger and more prolific on new wood.

Buddleja saligna

The plant is used for traditional medicinal purposes, the roots as a purgative and the leaves to treat coughs and colds. The wood is very fine grained and was used to make small pieces of furniture. The straight branches were used to make fence posts. The false olive was used to make asseggai handles. It also makes good fuel wood as it burns with an intense heat. The large amounts of pollen and nectar it produces makes it popular with bee farmers. May be used as Bonsai.

Buddleja saligna is easily grown from seed or cuttings.
