Plant Profile: Digitalis purpurea

Foxglove, a striking European import, showcases tall and vibrant blooms in a variety of colors. This plant thrives in moist, well-drained soil rich in organic matter, which should be kept consistently damp. It flourishes best when provided with afternoon shade. As a biennial, foxglove produces only a rosette of leaves in its first year, while in the second year, it sends up a tall spike adorned with densely packed, showy flowers on one side. To prevent an overabundance of seedlings, it’s advisable to deadhead after flowering; however, leaving some flowers to go to seed is essential for establishing a lasting planting, akin to perennials.

Incorporate foxglove into your perennial flower bed to introduce vertical interest. They create a stunning display when positioned in front of walls and shrubs or when planted in groups.

Previously classified under the family Schrophulariaceae, foxglove is a quick-to-identify erect perennial herb that can reach heights of 2 to 5 feet. It typically blooms from late spring to early summer and is well-suited for shady areas, woodlands, and natural settings, as well as borders. During dry spells and intense southern heat, it requires ample watering. This plant prefers partial shade and thrives in moist, well-drained, acidic soils rich in humus. Be mindful of potential issues with fungal diseases, aphids, Japanese beetles, and mealybugs.

The 'Excelsior Hybrids' variety features flowers that bloom around the rachis, available in soft pastel shades with noticeable markings on the tubular flowers, making them relatively easy to appreciate.
