Agastache ‘Blue Boa’ is a sensational garden plant. From late spring to frost you can enjoy the show of this easy bloomer. The big flower heads are different from your average Agastache, each dense floral spike is around 12cm long and their brilliant, violet blue shades glow in the sun’s light.
Since its release it has won numerous awards in the U.S. perennial trials. For us it blooms November to May.
Agastache ‘Blue Boa’ has big, bright to mid green fragrant leaves and a nice, upright habit. The foliage is wonderful planted along paths where you can brush up against it, or you could pick a sprig or two and bring indoors to enjoy in a vase.
Agastache are edible and can be used in salads or teas.
Standing up to heat and tolerant of poor soils, so long as they are well drained, Agastache are ideal for providing long lasting colour as a dry garden plant. Agastache plants prefer a full sun to light shade position, they need water to establish, then you only need to worry if rainfall is low.
We recommend dead heading your Agastache flowers regularly during the season to encourage more blooms. It is a good idea to cut your plants back to the ground in winter or early spring to maintain a healthy bush and allow the new growth to shine.
Agastache is also known as 'Hummingbird Mint', and is a native to the south western U.S.A.
