Hyssop


Agastache selections

Hyssop

This hard-working group of perennials does so much. They bloom for a long time in wonderful colors atop tall, striking plants. They produce a nectar that is irresistible to hummingbirds and butterflies. Most are heat and drought tolerant. And their foliage and flowers are fragrant, with scents ranging from licorice to bubblegum.

Most require well-drained soil and prefer full sun, although they will tolerate light shade.

Plant It With
Globe thistle

The stiff upright stems and steely blue flowers of globe thistle complement the airiness of hummingbird mint and team well with anise hyssop.

Mallow

Hollyhock mallow closely matches hyssop in height and growing requirements. Its pink flowers blend well with the color range of hyssop blooms.

Veronica

Veronica is a great foreground plant for hyssop. Its long season of bloom of pink, blue, or white spires sets off the foliage and flowers of hyssop.
