Agastache 'Summer Sky' (Hummingbird Mint) is a compact and bushy, upright herbaceous perennial forming a low mound of ovate, aromatic, bright green leaves. From early summer to fall, it boasts showy spikes of glowing violet-blue flowers with dark calyxes for a great floral display. A real feast for the eye. The flower spikes add lovely vertical lines to the landscape.
- Grows up to 24 in. tall (60 cm) and 20 in. across (50 cm). The aromatic leaves exude a minty scent when crushed.
- Easily grown in full sun, in well-drained, fertile soils. Good drainage is particularly important. Although a drought-tolerant plant, it might need watering in extreme dry weather spells.
- Provides a bold visual impact in beds and borders, cottage gardens, city gardens, gravel gardens, butterfly gardens, or patio containers over a very long season.
- Ideal to add color to the late-season garden when many other plants are fading.
- Creates a stunning effect when mixed with other perennials or planted en masse.
- Attracts streams of hummingbirds, butterflies, and other beneficial pollinators.
- Generally disease and pest-free (might occasionally be subject to powdery mildew) and resistant to deer and rabbits.
- Deadhead spent flowers to promote additional bloom.
- Propagate by division or by semi-ripe cuttings.
