Agastache ‘Blue Boa’ is a sensational garden plant. The big flower heads are different from your average Agastache, and their brilliant violet blue shades glow in the sun’s light. Each floral spike is around 12cm long. From late spring to frost you can enjoy the show of this easy bloomer.

Agastache ‘Blue Boa’ has big, bright to mid green leaves and a nice, upright habit. Since its release it has won numerous awards in the U.S. perennial trials.

Agastache ‘Blue Boa’ is fantastic in dry beds, cottage gardens, rock gardens and containers, and it is an excellent plant for attracting birds, bees and other beneficial insects to your garden.

We recommend you dead head your Agastache flowers regularly during the season to encourage more blooms. Or, if that seems like too much bother, give them a good hair cut midsummer, add some fertiliser and await a second flush.

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 will only have to worry if rainfall is low, however the flowering season will last longer if the plants are kept moist.

Allow the stems to remain in winter for the first season, cutting them back early spring to allow for the new growth.

Agastache is also known as 'Hummingbird Mint', and is a native to the south western U.S.A.
