Lavender has a familiar, spicy-sweet scent that is popular for a multitude of bath and body products, as well as being renowned for its ability to calm and relax the senses. You can grow your own lavender easily. Collect seeds from what you've grown for a new crop next year.
Cut flower stems as soon as the flowers are fully opened, but wait until the weather is dry and the morning dew has evaporated.
Tie bundles of flowers together by the stems.
Put a brown paper bag over each bunch of flowers and secure it below the flowers with gardening twine.
Hang the flower bunches upside down in a dry place where they won't be disturbed; wait a week or two.
Take the bundles down and shake gently, then, keeping the flowers inside the bag, rub gently on all sides to remove the flower seeds completely from the stalks.
Untie the bags, keeping them right-side-up, and remove and discard the stems.
Store the harvested lavender seeds in an airtight container and use within a year; lavender seeds have a short shelf life, according to Mountain Valley Growers.
