Plant Profile: Iberis umbellata

Candytuft, belonging to the mustard family, thrives in well-drained soil but is adaptable to various soil types, including less fertile and highly alkaline conditions. It’s important to allow the soil to dry out between waterings, as excessive moisture can lead to its decline. This plant does not thrive in shaded areas. After its blooming period, it may appear somewhat unkempt, so incorporating other late-blooming flowers in the same space can enhance the garden's appearance.

For optimal growth, sow seeds in the spring following the last frost for summer blooms, or in the fall for the following year's flowers. You can collect seeds by bagging the seed heads as they dry, then breaking open the pods to extract the seeds, ensuring they are clean and dry before storing. Additionally, candytuft may self-seed in certain locations.

This plant is a beloved choice for cottage gardens, fitting well in compact spaces, along pathways, on sunny slopes, or even in containers.
