Tarragon grows all spring and summer before it produces many yellow, single marigold-like blossoms, but that is just a bonus because the main reason to grow it is for the flavored leaves. Try growing Tarragon in an herb garden, flower bed, or container. Let it be the bright spot in your herb garden, which often needs a boost by summer’s end. The upright plants pair well with other fall bloomers. Plants bloom lightly in the spring, then profusely in the fall. Plants need full sun or partial shade and must have well-drained soil. Given that, they grow easily and without fuss. Although drought tolerant, they will be fuller and bloom best if kept moist. Snip fresh sprigs as needed. Before frost, harvest the stems by cutting them at the base and letting them air dry on a screen, or bundle a few together at the base to hang upside-down to dry.
