Growing Guide

When to Grow

Start seeds indoors 8 to 10 weeks before the last expected frost date for 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. 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. Lavender Martini adapts well to a range of moderately fertile, well-drained soils and is particularly well suited to container growing given its compact mature size. Space transplants or thin seedlings to 12 to 15 inches apart. Avoid heavy, poorly drained soils, which are the primary cause of decline in agastache. For container growing, use a well-draining potting mix and ensure pots have adequate drainage holes.

How to Grow

Lavender Martini is drought-tolerant and low-maintenance once established. Water regularly during the first season to encourage strong root development, then reduce irrigation as plants mature. In containers, water consistently but allow the growing medium to dry somewhat between waterings to prevent root issues. Deadhead spent flower spikes to encourage continuous blooming through the season. Cut plants back to the ground in early spring before new growth emerges, and apply a light protective mulch in winter at the colder end of the hardiness range. 

How to Save Seeds

Lavender Martini 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
