I?ve grown a number of Hummingbird Mints over the years and they always perform well as long as they are planted in full sun and in a well drained soil that isn?t over-watered. Bolero is a unique selection first offered in 2011 that only reaches a height of about 18 inches. Its flowers are made up of rose-purple corollas with purple calyces but what sets this Agastache apart is its bronze tinted foliage. A hybrid of A. cana x A. bareri, it is heat tolerant and moderately tolerant of drought. Though they are sometimes referred to as Mosquito Hyssops, Agastaches are excellent plants for attracting hummingbirds.
