Why Grow Agastache aurantiaca?
- Pollinator magnet: The tubular nectar-rich flowers attract hummingbirds, butterflies, bees, and other beneficial insects from summer into early fall.
- Edible and aromatic: Leaves and flowers can be used in teas, salads, and garnishes, with a subtle scent reminiscent of citrus and mint.
- Drought resistance: Once mature, this perennial thrives with minimal watering, making it ideal for xeriscaping and water-wise gardens.
- Low maintenance: Few pests, minimal disease problems, and dieback in winter requiring only seasonal tidying.
- Deer and mosquito resistance: The aromatic foliage repels deer and may discourage mosquitoes from your garden.
Botanical Characteristics
Agastache aurantiaca forms a compact to upright mound of narrow, aromatic green leaves. Its slender spikes of tubular, apricot-orange to coral flowers bloom from midsummer to early fall, standing out beautifully both against its foliage and as cut flowers in arrangements. The plant usually matures to 2-4 feet in height and up to 18 inches in width, making it suitable for borders, rock gardens, and containers.
Flowering and Seasonal Beauty
- Bloom season: Summer to early fall
- Flower shape: Tubular, ideal for long-tongued pollinators
- Color attractants: Peach, apricot, orange hues
- Fragrance: Leaves and flowers exude a sweet, herbal scent
Planting Agastache aurantiaca
Choosing a Site
- Select a location with full sun â at least 6 hours daily encourages abundant flowering and dense, compact growth.
- Partial shade is tolerated, but may reduce flowering.
- Best in protected sites sheltered from cold winter winds if you are at the edge of hardiness zones.
Soil Preparation
- Well-draining soil is critical; sandy loam or gritty soils are ideal.
- Amend heavy clay or poorly drained soils with coarse sand, gravel, or organic matter to prevent root rot.
- pH range: 6.5 to 7.5 (neutral to very slightly acidic).
Planting Instructions
- Direct seeding: Sow seeds just below the surface after the last frost when temperatures are reliably above 60°F. Thin to 10-12 inches apart when seedlings are 1 inch tall.
- Transplants: Start seeds indoors 4-6 weeks before your last frost date. Transplant young plants into the garden once night temperatures remain above 50°F.
- Water thoroughly after planting to help roots establish, but do not keep the soil overly wet.

Container Growing Tips
- Use a deep, wide container with drainage holes and a light, gritty potting mix.
- Containers should be at least 12 inches deep for robust rooting.
- Ensure consistent moisture, but never let roots sit in water.
Care and Maintenance
Watering
- Low water requirements: Water deeply only when the soil is completely dry. Once established, Agastache aurantiaca tolerates drought well.
- Avoid overhead watering to reduce risk of powdery mildew.
Fertilizing
- Apply compost or a slow-release, balanced fertilizer in spring to encourage healthy growth.
- Heavy feeding is not necessary; avoid high-nitrogen fertilizers that may promote weak growth or reduce flowering.
Pruning
- Deadhead spent blooms regularly to prolong the flowering season.
- Cut stems down to 6 inches in mid-spring, after winter dormancy, to encourage bushy regrowth.
- Leave seed heads standing late into fall and early winter to feed birds and provide winter interest.
Overwintering
- Mulch lightly in late fall in colder zones (zone 6) to protect the crown from freeze-thaw cycles, but avoid mulching tightly against the stems, which can encourage rot.
Common Pests and Problems
- Flea beetles and slugs: May chew on leaves, but rarely cause significant damage to mature plants. Use organic slug bait or hand-pick pests if needed.
- Powdery mildew: Occasional in humid conditions or with poor air circulation. Improve spacing, choose sunny sites, and water at the base to mitigate risk.
- Root rot: Most common in heavy, wet soilsâamend soil for drainage and avoid overwatering.
Propagation
From Seed
- When to sow: Indoors 4-6 weeks before last frost, or direct seed outdoors after the last frost when soil has warmed above 60°F.
- Covers seeds very lightly with soil; lighting aids germination.
- Seedlings emerge in 7-20 days.
From Cuttings
- Take 3- to 5-inch stem tips in spring or early summer.
- Remove leaves from the lower half, dip in rooting hormone, and plant in moist, well-aerated medium.
- Keep cuttings warm and moist until roots develop, then transplant outdoors.
Landscape Uses
- Borders and edging: Compact varieties like Apricot Sprite are ideal for the front of mixed beds.
- Pollinator or cottage gardens: Pairs beautifully with milkweed, ornamental grasses, or yarrow.
- Containers: Works well due to upright growth and low water needs.
- Herb gardens: Edible flowers and leaves add interest and culinary options.

Q: Does Agastache aurantiaca attract pollinators?
A: Absolutely. The plantâs tubular flowers are favorites for hummingbirds, bees, butterflies, and even moths, supporting healthy local ecosystems.
Q: Is it deer or rabbit resistant?
A: Yes. The aromatic foliage typically deters deer and rabbits, making it a reliable choice in areas troubled by wildlife.
Q: How often should I water mature plants?
A: Water only during prolonged dry spells. Established plants thrive best with deep, infrequent watering.
Q: Can it survive winter in colder climates?
A: Agastache aurantiaca is hardy down to USDA Zone 6. In colder regions, mulching and planting in sheltered spots improves winter survival.
Tips for Success: Maximizing Bloom and Plant Health
- Avoid over-fertilizing; too much nitrogen restricts blooms and encourages weak, leggy growth.
- Space plants at least 12 inches apart to ensure sufficient air flow and minimize disease risks.
- Remove faded flower spikes to extend blooming season up to the first fall frost.
- Consider companion planting with grasses, yarrow, and lavender for a drought-tolerant, pollinator-friendly garden bed.
