How to Sow and Plant

Sow seeds indoors 6–8 weeks before the last frost or directly outdoors after frost risk has passed.

Lightly cover seeds with soil and keep evenly moist.

Maintain temperatures around 18–22 °C for germination, which usually occurs within 10–20 days.

Transplant seedlings once they are strong and frost danger has passed.

How to Grow

Plant Agastache in full sun with well-draining soil.

Remove spent flower spikes to encourage continuous blooming.

Minimal fertilisation is needed; overly rich soil may reduce flowering.
