thoroughwort

Water Thoroughworts deeply but no more than once a week, especially during the hot summer months. In spring and autumn, water the plants every 4 to 5 days. During winter, wait until the soil is completely dry before giving the plants a deep drink. If you water too frequently, the roots can remain constantly wet and rot. Thoroughworts also appreciate a light misting during hot summer days to help cool off the plants.

Thoroughwort (Conoclinium greggii) is a plant species that graces gardens with its tall, feathery-leafed stems and clusters of small, lavender-colored flowers. This species generally does best when planted in full sun, though it can tolerate some shade. To get the most out of this plant, it should receive at least 6 hours of sunlight per day, though it can still thrive with just 4 to 5 hours of direct sunlight each day. For optimal health and growth, however, thoroughwort should be exposed to at least 6 to 8 hours of sunlight per day. During the hottest parts of the day, it may benefit from some afternoon shade during the summer months.

Thoroughwort require very little pruning, however if desired it is best done in late winter or early spring, after the last frost. Start by removing dead and diseased branches, then a light shaping can be done if desired. This species of plant blooms best when left unpruned, so unless there is an issue with the shape of the plant, it is best to avoid heavy pruning.
