Agastache with their bottle-brush flowers are perfect for giving height to the border. The leaves tend to be aromatic and the flowers are long lasting. These perennial plants are attractive to butterflies .
Agastache work well when planted with Monarda, Euphorbia, Leucanthemum, Sidalcea or Grasses where their spiky flowers can pop through the foliage. Add a dash of Crocosmia to add a little pizzaz.
