Lavender Seed Propagation – How To Plant Lavender Seeds

Growing lavender plants from seed can be a rewarding and fun way to add this fragrant herb to your garden. Lavender seeds are slow to germinate, and plants grown from them may not flower in the first year, but if you’re patient and willing to put in the work, you can generate beautiful plants from seeds. Read on to learn about starting lavender from seed.

Germinating Lavender Seeds

The first step in lavender seed propagation is choosing a variety and germinating the seeds. Be aware that not all cultivars will come true when you propagate by seed. If you are determined to grow a particular cultivar, you’re better off using cuttings or divisions to get new plants. 

Some good varieties for starting by seed are Lavender Lady and Munstead. It can take one to three months for lavender seeds to germinate, so start early and be patient. 

Also, be prepared to germinate them indoors. Lavender seeds will need warm temperatures, between 65 and 70 degrees F. (18-21 C.). If you don’t have a warm spot or a greenhouse, use a heat mat to keep your seeds warm enough.

How to Plant Lavender Seeds

Use shallow seed trays and just barely cover the seeds with soil. Use a light soil or a vermiculite blend. Keep the seeds moist but not overly wet. A sunny spot is a great location to keep the soil from getting too wet and to add warmth. Your lavender seedlings will be ready to transplant once they have several leaves per plant. 

Your first year of growth will not be impressive, but by year two, expect to have large, blooming lavender. Starting lavender plants from seed is not difficult, but does require time, some patience, and a little extra space for your seed trays.
