In the meantime, what's a fan to do? Why not plant a garden this spring, featuring some of the plants mentioned in the Outlander books?
Here are some suggestions, with links to the seeds offered by Botanical Interests.
Forget-Me-Nots (Myosotis sp.) This is the little plant that started it all. Claire first spotted this plant when she and Frank visited the standing stones. She returned later to collect the flowers, got a little too close to the cleft between the stones, and the rest is historical fiction.
Foxglove (Digitalis sp.) This colorful biennial has long been used as a heart medicine. Enjoy the flowers but do not eat any part of this plant.
Garlic chives (Allium sp.) Garlic has been used as an antibiotic for centuries. The time to plant regular garlic is mid-summer, but you can get the benefit of the medicinal properties of this plant family by using garlic chives. Chives are perennials - they reappear early every spring.
