Agastache nepetoides


Yellow Giant Hyssop

A unique and impressive plant for its upright habit that will flower in summer with densely packed five inch long spikes of yellow-whitish green flowers. The bees will love you for this one and the birds will feed on the seeds in the winter. Plants grow 5-6 feet tall and can be used in open woodlands to full sun with moisture retentive soils that drain well. Useful in the perennial border, native wildflower area, woodland or butterfly gardens - best effect planted in large groups with plants spaced-out 18 inches apart, will self seed on open ground. Not the showiest bloomer, but loved by a diverse group of insects that will provide weeks of entertainment and if you like to take pictures of insects - this plant like most of the hardy Agastache, is indispensable. The dried stems in the winter are attractive. Started in late winter, plants will bloom the first year. Easy to grow and transplant, seedlings are large enough to plant out into the garden in 5 to 8 weeks after germination. Can also be sown directly on bare ground in late winter/early spring while the ground is still cold with good results.
