Then mix the seeds with an equal volume of sand or moist vermiculite. Place everything in an airtight plastic bag and leave it in the refrigerator for 30 to 90 days (cold stratification). Sow directly in the desired location in the spring, as soon as the temperature becomes suitable, or in the fall for natural germination the following spring.
Tick-trefoil is a versatile and eco-friendly plant, perfect for improving soil quality while adding beauty and biodiversity to gardens. Its hardiness and usefulness make it a great choice for renaturalization projects and low-maintenance spaces.
