Heat Wave Hyssop (also known as Agastache or Hummingbird Mint) ignites the garden with sizzling spikes of magenta-pink flowers that hummingbirds and butterflies simply adore. Blossoms blaze through the summer heat, shining against a backdrop of fragrant, blue-green foliage. Plant this water-wise selection at the back of mix beds and borders for a lasting one-two punch of color. (Agastache hybrid)
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
24-36" tall x 18-24" wide. Heat Wave Hyssop (also called Agastache or Hummingbird Mint) is exceptional selection of Hyssop with good heat tolerance and drought resistance. Heat Wave grows beautifully in containers and hot, dry sites. Plants bloom over a long season and hold their pink calyxes long after flowers fade. Pollinators are attracted to the ready source of nectar while goldfinches love feasting on seeds of Heat Wave Hyssop late in the season. The licorice-scented foliage can be steeped in tea or used to flavor dishes. Flowers and foliage also make lovely, fragrant cuttings. An upright, clumping growth habit makes ‘Heat Wave’ ideal for massing in borders or cottage-style plantings. Provide hyssop with good drainage and plenty of sunshine for best performance. Avoid over-watering once plants are established. Heat Wave is deer and rabbit resistant.
