Foxgloves are easily grown from seeds but will not flower until the plant reaches one year of age.
The perennial foxglove ( zones 4-10 ) is an excellent addition to the shade garden that will add beauty and color for many years.
Where to grow: The plants prefer well draining acidic soil conditions. Choose a location that offers shade. When planting add abundant compost or organic matter to the soil. Mulching with oak leaves in the fall will help the plants overwinter.
Foxglove will grow best in rich, well draining soil with humus or sand mixed in, but any garden type soil will work fine as long as it is on the acidic side.
Space foxglove plants about a foot and a half apart to offer enough room for the light green foliage that forms a large rosette shaped mound. Foxgloves spread rapidly and it is advised that every three to four years the plants be divided and transplanted into a new location. Foxgloves easily naturalize an area and offer a wonderful meadow appearance when allowed to grow wild with other wildflowers.

Foxgloves are adored by bees and hummingbirds so plant in a location where you can enjoy watching the activity. Locating them outside a window is often a wonderful way to enjoy the plants.

Apply 3 to 4 inches of mulch around the base of the foxglove plants. The mulch offers summertime protection for the plants root system against the intense heat, the mulch also offers wintertime protection, it helps soil retain water and keeps weeds down. Peat moss or bark chips are ideal mulch for use around foxgloves.

Water foxgloves weekly to keep the soil moist. The foxglove does not tolerate dry soil conditions well. Use a drip irrigation system or a soaker hose so the plants flowers and foliage does not become wet. The large flower spikes will easily be weighed down with water and often bend or break under the weight.
Clip spent flower heads to encourage side shoots to develop and flower. Leave the flower heads on the plant if you wish the plant to produce ample seeds and spread.
