Agastache
Lovers of heat, these tough and drought-resistant Mint family relatives guarantee terminal spikes adorned with brightly colored, tubular flowers just about all summer long. Agastaches are easily grown in well-drained soil, and will bloom more profusely, over an even longer period of time, if the flowering stems are cut back midseason.
This drought tolerant bushy perennial is prized for its more manageable compact habit. With erect stems tinged a dusty grape, wine-purple calyxes, deep peachy orange flowers, and mint-scented triangular green leaves sporting silvery undersides, the stunning shades of an evening sky will light up your garden all day long. Easy-to-grow ‘Apricot Sprite’ can be planted in the company of Mediterraneans such as Geranium harveyi, where it will undoubtedly entice gardeners and hummingbirds alike.
