When shopping for your garden, it’s easy to overindulge in spring-blooming plants. There are so many wonderful Trees, Accents, and Spirits that flower then! But consider the other seasons. Late summer and early fall, for example, is a quiet time when summer bloomers are losing steam and autumn foliage has yet to color up. Dark Knight Bluebeard has got you covered there. This dashing Spirit opens its intense cobalt-blue blossoms in August and September. What’s more, the vivid flowers will please not only you but also the monarch butterflies heading south to Mexico. Send them on their way with some flower fuel!

The Story

This Bluebeard, a.k.a. Blue Mist Shrub, is a hybrid Spirit whose parents come from China and neighboring areas. The hybrid first appeared in the garden of an English plantsman, Arthur Simmonds, in the early 1930s. Since then, various selections of this special Bluebeard have been introduced to the public. The exact origins of Dark Knight Bluebeard are unclear, but it is believed to have come from the United States. Valued for its deep purple-blue blooms, its pretty silvery-green foliage, and its dependability, it has remained a popular choice over the years.

The Details

Got deer? Dark Knight Bluebeard has aromatic leaves that deer find distasteful. They tend to leave this fragrant Spirit alone. If rabbits are a problem in your garden, Dark Knight will give you some peace of mind also, as all kinds of chewing critters are unlikely to browse it.

How to Grow

Give Dark Knight Bluebeard a sunny spot in loose, free-draining soil (no sticky clay). If your soil is too heavy for its liking, you can always grow the plant in a container or a raised bed. It isn’t fussy about soil pH. As with all Spirits that develop a woody framework, wait until late winter or early spring to do any major pruning, especially in cold climates. Late-season pruning can encourage tender growth that is vulnerable to sudden freezes. Cut Bluebeard back hard to new green buds that appear in spring. Feed at that time with Bower & Branch Elements® Fertilizer.
