Summarize this article:

Foxglove seed is readily available in seed packets on most flower seed stands. If you decide to start foxglove from seed, you'll need to be ready to plant it in early summer. If you're planting seedlings, you may plant in spring or fall. If you're starting from seed, use 4-inch seed trays with seed compost. Lightly press the seeds into the compost. Do not cover the seeds with more compost once they are sown, since they require light to germinate. Plan to plant the seedlings when they are a few inches tall. You can also grow foxglove inside or in a greenhouse before planting outside. You'll want to use a large container that is at least 16 inches (40.6cm) in diameter, with drainage holes at the bottom. Use a potting mix with 2 inches (5.1cm) of compost mixed into the top inches and plant the foxglove so that the root ball is covered. Make sure to place your foxglove where it will get 3 to 6 hours of direct sun each day while it's inside. Try a south or west-facing window. Cover the plant's soil surface with a 2-inch deep layer of mulch. This will keep the soil moist. Water the plant deeply about twice each week, checking the soil first if the soil is dry at a depth of two inches, water. Fertilize the foxglove once in the spring before it flowers, using a 10-10-10 water-soluble fertilizer. Mix in one tablespoon of fertilizer in a gallon of water for each plant. Foxglove prefer full sun or light shade. Find a place outdoors that isn't too windy and gets plenty of sun for most of the day. They should be protected from wind as they are easily buffeted about and can change their growth shape if assaulted by wind too frequently.If your climate is very hot, semi-shade is acceptable. Foxglove like soil that is deep, moist, and acidic. Look for a spot that drains well, rather than holding too much water. If you see puddles in an area after a heavy rain, it probably doesn't drain well enough to be a good home for foxglove. Use a garden rake or hoe to loosen the soil and rake in compost to a depth of about a foot. This will make sure the soil is suitably rich and ready for the foxglove to take root. You can use fertilizer instead of compost, but be sure to use a light application. Too much fertilizer will harm the foxglove. They should be twice as wide as the root balls of the seedlings, and deep enough so that you can fit the entire rootball underground. Set the root balls into the holes and lightly pat soil around the bases of the stems. Water the area thoroughly.

Summary:
Purchase seed or seedlings from a garden store. Start your plants indoors. Find a good place to plant foxglove. Look for suitable soil. Prepare the planting site. Dig holes spaced 2 to 4 feet (0.6 to 1.2m) apart. Plant the foxglove.
