Gardeners' Notes:


On Aug 2, 2016, coriaceous from ROSLINDALE, MA wrote:

This species isn't long-lived (usually under 10 years). Hard pruning (to 6") annually in early spring helps it renew itself and improves bloom.

All B. davdii cultivars require weekly deadheading for them to look and bloom its best.

Butterfly bushes may be good nectar sources for adult butterflies, but they are not food sources for the caterpillars of any Lepidoptera native to the continental US.

In some places, B. davidii can be an invasive weed: England, France, New Zealand, and the states of Oregon and Washington. It has naturalized in eastern N. America but is not considered invasive there. Recent cultivars are usually selected for dramatically reduced fertility.This species has naturalized along the west coast of N. America from BC to Califo... read more

The best way to attract butterfly’s to your home is to plant a butterfly-friendly garden. Butterflies love brightly colored flowers, with red and purple being some of the more popular colors they’re attracted to. They prefer to land on larger flowers (for support) that have a faint but fresh flower smell.
If you want to make a garden where there is a lot of butterflies, this bush is the best.

This plant is "hanging in there" during the drought, now into 2015. Hardly getting any water, it has remained mostly green, but with a lot of dead branches and leaves, which must be picked and pruned. This plant will tolerate being in the shade part of the day, which in my humble opinion, gives it a respite of sorts. It hardly needs fertilizing, but once a year, with an all-purpose liquid. It's very low-maintenance.

Buddleia - English Butterfly™ Peacock™ Butterfly Bush

Peacock™ has rich pink distinct blooms in which the flowers radiate outward from the plant almost like rockets. The flower heads are also the largest of three in the English Butterfly™ series easily reaching 12 to 14 inches in length. It's a neat compact plant so even gardeners with limited space can attract butterflies and hummingbirds. Perfect for cut flowers, perennial or shrub borders, in masses or groupings. Will bloom best if cut back heavily in the spring.

The English Butterfly™ series are colorful Buddleia varieties that won't crowd their neighbors! These three new cultivars were developed in England, and are just now making their way across the Atlantic. Roughly a third the size of other butterfly... read more
