Growing Guide

When to Grow

Start seeds indoors 8 to 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 for this native species. In Zones 6a–9b, established plants overwinter reliably; in colder zones, treat as a long-blooming annual started fresh each spring. If you're not sure how to find your first and last frost dates, consult our blog post Our Experts Answer Questions, Share Resources.

How to Sow and Plant

Surface sow seeds by pressing them lightly into moist, well-drained soil without covering. Texas Hummingbird Mint is well adapted to the lean, rocky, and sandy soils of its native Texas and New Mexico habitat—avoid heavy clay or poorly drained conditions. Space transplants or thin seedlings to 18 to 24 inches apart to allow for the plant's neat, clumping mature habit. No heavy soil amendment is needed; overly rich or moisture-retentive soils can reduce plant longevity and fragrance intensity.

How to Grow

Texas Hummingbird Mint 'Heather Queen' is drought-tolerant and low-maintenance once established, thriving in heat and full sun with minimal care. Water regularly during the first season to encourage strong root development, then reduce irrigation as plants mature. Excellent drainage is essential year-round and particularly critical through winter, when wet soils are the leading cause of plant loss. Deadhead spent flower spikes to sustain the long blooming season, and cut plants back to the ground in early spring before new growth begins. 

How to Save Seeds

Texas Hummingbird Mint 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
