Description

(Agastache auraniaca). Delicious minty-citrus tea plant; a must in the herb garden and kitchen! Southwest native perennial that is irresistible to hummingbirds, butterflies, bees and other beneficials. Agastache Navajo Sunset wafts an incredible citrus scent; the open airy plants produce beautiful orange blooms. Ideal for xeriscape gardens, this variety is water thrifty and thrives in poor soil. Plants reach 28 inches tall and 30 inches wide, great for the perennial border or for the tea garden!

Growing Tips: Navajo Sunset is a vigorous, open-habited Southwest native agastache with a generous spread and an outstanding citrus-mint fragrance that makes it a standout in the tea garden and herb border alike. Its vivid orange blooms are produced on airy, branching stems that hummingbirds, butterflies, and bees find irresistible throughout the long blooming season. As a true xeriscape plant, it thrives in poor, dry, well-drained soils with minimal irrigation once established—rich soils and overwatering are the most common causes of decline.

When to Grow

Start seeds indoors 8–10 weeks before the last expected frost date for the best chance of first-year bloom, or direct sow outdoors in early spring once soil can be worked. Seeds require light to germinate and should be surface sown without covering. A brief cold stratification period of two to four weeks may improve germination rates. In Zones 6–10, established plants are reliably perennial and will return each season without replanting.

How to Sow and Plant

Surface sow seeds by pressing them lightly into moist, well-drained soil without covering. Navajo Sunset is well adapted to poor, sandy, and rocky soils that reflect its native Southwest habitat—avoid heavy clay or poorly drained conditions. Space transplants or thin seedlings to 24–30 inches apart to accommodate the plant's naturally wide, open mature habit. No soil amendment is needed; overly fertile or moisture-retentive soils can shorten plant lifespan and diminish fragrance.

How to Grow

Navajo Sunset is exceptionally drought-tolerant and thrives with minimal care once established. Water regularly during the first season to support strong root development, then reduce irrigation significantly as plants mature. Excellent drainage is essential year-round, particularly through winter when wet soils are the leading cause of plant loss. Deadhead spent flower spikes to encourage continuous blooming through the season, and cut plants back to the ground in early spring before new growth emerges. 

How to Save Seeds

Navajo Sunset produces small seeds in clusters along the dried flower spike, typical of the Lamiacae family.

  • Allow a few flower spikes to dry fully on the plant at the end of the season
  • Harvest seed spikes by cutting and placing in a paper bag to capture any that fall
  • Dry thoroughly in a cool, well-ventilated location before cleaning
  • Store cleaned seeds in a sealed, labeled container in a cool, dry, dark place for up to 3 years
