AGASTACHE 'Heather Queen'
Plant Common Name
Heather Queen Hyssop, Hybrid Hyssop
Everblooming and richly colored, the fragrant hybrid hyssop ‘Heather Queen’ is a delight to hummingbirds and butterflies and will boost the color level in any sunny summer garden. This compact, clump-forming herbaceous perennial produces dense upright clusters of rose-pink tubular flowers. It begins blooming in early summer and will continue up until frost if regularly deadheaded. Like most Agastache, its small, soft green leaves are aromatic when crushed.
Full sun is required for best flowering and performance and average soil will suffice but well-drained, slightly alkaline, loam is preferred. Beware wet, heavy, clay soils as these will cause root and crown rot, particularly in winter. One of the biggest perks of this everblooming perennial is that it’s remarkably heat and drought tolerant once established and will shine when many other plants in the garden are flagging. ‘Heather Queen’ self-sows gently but the variable offspring will not be true to parent.
This is one of the best ornamentals for hot summer sun. It’s so tough, it’s almost sustainable. Just let nature do its thing. Plant it in any sunny flower garden, container planting or hummingbird garden.
