Foxglove: Digitalis purpurea Giant Shirley
The 2?4 foot tall flower spikes of 'Giant Shirley' foxglove bear pink, rose, or white flowers, each with a speckled throat, above large, toothed leaves. Unlike many other foxgloves, the flowers of this cultivar uniformly encircle the spike and are held horizontally instead of nodding. Great as a cut flower, this self-sower adds drama, height, and form to a border or container. Profile
did you know?You can tell the color of a foxglove before it blooms. Just look at the petiole (leaf stem) to see if it is flushed with a pink or purple color; white-flowered plants lack pigment, so their leaf stems are greenish-white. general maintenance:Deadhead after flowering but allow some seed production to encourage self-sowing in the garden. Watch for seedlings and mark or transplant young plants in fall. pests/diseases:Anthracnose and leaf spot may occur. controls:To discourage anthracnose and leaf spot, space plants for adequate air circulation and avoid wetting leaves when watering. Remove diseased leaves where practical, and remove and destroy severely infected plants. how to sow/plant:Choose a well-drained site, amend with compost or well-rotted manure, and direct sow barely covering seeds in fall in Zones 7?8; in cooler areas sow in late spring. Thin young plants to a distance just shy of their mature spread. Foxglove is a biennial that is best started from seed each year. water and fertilize:Maintain soil moisture all season. Apply slow-release fertilizer when planting, or feed biweekly with a balanced all-purpose fertilizer, following label directions. garden hint:Foxgloves self-seed and appear mysteriously in other parts of the garden. They seem to know the spots where they will thrive, so let them self-sow where they will. features:
