|Should they be planted in full sun? After the flowers die what should I do?|
|Foxgloves thrive in Zones 4-10 except in Florida and along the Gulf Coast. In temperate climates they prefer light shade, but in hot areas they should be kept in partial to full shade. They do best in moist but well-drained, slightly acid soil.
Plant foxgloves 15 to 18 inches apart. You can remove the spent flowers by cutting the flowering stalk off before seed pods form. If you do this, your plants may produce a second smaller flowering stalk later in the season.
Perennial foxgloves can be started by dividing and resetting clumps in early spring or fall, but are more commonly grown from seeds. Sow the seeds in mid- to late spring to get flowers the following summer. In exposed areas, staking may be required for taller varieties. Good mulching is a must. To prevent overcrowding, divide clumps after three or four years of flowering. In areas where the growing season is at least 150 days, foxgloves will self-seed readily, making them an excellent candidate for naturalizing.
