Thalictrum delavayi


Thalictrum delavayi, is often known as Lavender Showers or Chinese Meadow Rue.

Clouds of lilac-mauve

Because each plant creates clouds of lilac mauve, billowing up to an impressive. 1.2m.
And although each flower is small, the effect of a misty mass of flowers is beautiful.

Hardy in Dry Shade

Lavender showers is noted for its ability to flourish and flower profusely in shaded gardens. 
But it is treasured by gardeners who contend with Dry Shade under trees and shrubs. Because Lavender Showers can really shine there, with a minimum of water and attention.
So Thalictrum delavayi, Lavender Showers, does best in Part Shade to Full Shade, but can tolerate Full Sun in cooler districts if well mulched.

Can tolerate summer humidity as well as dry soil

Thalictrum delavayi tolerates summer humidity well and so makes a very useful shade plant for sub-tropical gardeners.

Fragrance & cut flowers

The foaming froth of flowers have a delicate scent, and you can cut whole stems of heads to fill a vase.
They make excellent, long lasting cut flowers. 
The cloud of flowers also provides an excellent pollen source for bees during the long lasting flowering season.
And if you leave the flower heads to go to seed, they also provide winter feed for small seed eating birds such as finches.

More mists in the shade

Once established your Thalicrum delavayi will gently self-seed in the garden bed.
Meadow Rues are never invasive, and volunteer seedlings are always welcome to make more clouds of blossom at the back of the garden bed, or under trees and shrubs.
