This native perennial is a lovely member of the mint family. It occurs in mountainous areas of WA, OR and CA, and eastward to MT, WY and CO. It also occurs in southern British Columbia. Plants are highly scented, and the pink-lavender flowers attract numerous pollinators such as native bees and butterflies. For this reason, it has been added to our pollinator conservation mixes for the Southern Rocky Mountains.

Sowing: Direct sow in the fall, pressing the seed into the surface of the soil. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting on the surface of the soil. To start indoors, plant on the surface of a flat with bottom heat of 70 degrees F and consistent moisture. Germination should take place within 6-10 days. As soon as the seedlings are big enough to handle and there is no chance of frost, they can be transplanted.

Growing: Keep young seedlings watered. Medium to moist soil is best for this plant, but the plant is somewhat drought tolerant once it reaches maturity and adapts to many types of soil. Plants will bloom the second year from seed. It reseeds itself readily, so if volunteer plants are not wanted deadhead the faded flower spikes. This plant attracts bees, hummingbirds, and butterflies

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.


If you can’t find germinating and instructions online you can find them on the item page. Our goal is to save money everywhere we can so we can pass those savings on to you.
