Lemon thyme, known for its intense lemon aroma, can be a scraggly mat in the ground; confined n a container, however, it’s an attractive, upright mound of small, pointed, glossy green leaves. As the branches grow, they spread out and trail over the container’s edge; by early summer, they produce dense heads of lilac flowers that last well over a month.
How to grow lemon thyme
Lemon thyme is best grown from plants, not seeds, and should overwinter outdoors. The following spring, prune back to new growth. Plants eventually form hardened mats, which need to be divided or discarded. Trim plants over the growing season by cutting back stems. Lemon thyme will flower nicely if you let it, but cut back stems and fertilize afterward.
