Foxgloves (Digitalis purpurea) are a popular biennial plant that can be grown in gardens for their striking, bell-shaped flowers. Here are some tips for growing foxgloves and caring for them as a cut flower:
Planting: Foxgloves prefer well-drained soil that is rich in organic matter. They grow best in partial shade, but can tolerate full sun in cooler climates. Sow the seeds in the fall or early spring, and plant them about 18 inches apart.
Watering: Foxgloves need regular watering, especially during hot and dry weather. Water deeply once or twice a week, and avoid getting the foliage wet to prevent fungal diseases.
Fertilizing: Apply a balanced fertilizer in the spring, and again in mid-summer to promote healthy growth and flowering.
Pruning: Deadhead spent flowers regularly to encourage more blooms. Cut the flower stem at the base of the plant when the flowers are fully open. Many Foxglove and all heirloom Foxgloves will make millions of seeds and readily reseed themselves in your garden so deadhead to prevent seedlings.
Harvesting: Cut foxglove flowers in the morning, just after the dew has dried. Choose flowers that are fully open but not yet wilted. Cut the stem at an angle and place it immediately in a bucket of water. Foxglove should be harvested when 1/3 of the flowers on the spike are open. The rest of the florets will open in the vase. They tend to last about 5-7 days in an arrangement.
Care: Change the water in the vase every two days, and trim the stems at an angle each time. Keep the vase away from direct sunlight and drafts.
Note: Foxgloves are toxic if ingested, so keep them away from children and pets. Wear gloves when handling them to avoid skin irritation.
Colors and Hardiness Zone
Foxgloves come in a variety of colors and there are also species of foxgloves that are available. Here are some examples:
Digitalis purpurea: The common foxglove comes in shades of pink, purple, and white.
Digitalis grandiflora: This species of foxglove produces yellow flowers and grows up to three feet tall.
Digitalis parviflora: This species of foxglove is native to Europe and produces small, yellow flowers.
Digitalis lutea: This species of foxglove produces creamy yellow flowers and can grow up to four feet tall.
Digitalis ferruginea: This species of foxglove produces rusty orange flowers and can grow up to five feet tall.
Foxgloves are hardy in USDA zones 4 to 8, although some species may be more or less tolerant of certain conditions. In general, they prefer cool temperatures and moist, well-draining soil. In hotter climates, they may benefit from partial shade or protection from the hot afternoon sun.
