4-5' x 24" wide, (cutting propagated). Of all the hummingbird mints varieties High Country Gardens has released (and they are our specialty), this is our finest introduction. This stately hybrid between Agastache cana and Agastache barberi will be the centerpiece of any planting with its huge spikes of deep rose-pink flowers, raspberry-red calyxes and sweetly scented foliage. Flowering begins in mid-summer and continues for months, the spikes elongate up to a foot or more in length and intensifying in color with each passing week. Unlike any other Agastache I've grown, Ava's calyxes retain their intense coloration keeping the plant beautiful until hard frost. Or like fine dark-flowered Lavender, it can be picked and dried to make a fragrant everlasting flower. This plant takes two to three growing seasons to reach mature size and will live for many years when happy. Plant in enriched, well-drained garden soil. Fertilize annually in mid-fall with Yum Yum Mix and leave the stems standing through winter. Cut it back in mid-spring. Not recommended for fall planting in zone 5. Zones 5-10.
