Foxglove plants produce tall spikes of colour in your garden, with an abundance of small blooms on each spike. Technically, foxglove functions as a biennial, with the flowers growing from seed in the first year. However, you can treat them as perennials with proper maintenance after the plants bloom, Cornell University reports. Foxglove typically blooms between June and September, depending on the climate. To get your foxglove to grow like a perennial, you will need to care for it properly after the flowers appear.

Things you need
- Garden shears
Deadhead the foxglove blossoms by hand once about three-quarters of the flower spike has died back, Cornell University advises.
Continue monitoring the plant throughout the flowering season, continuing to deadhead the blooms on spent foxglove spikes.
Cut back the spikes with garden shears once the flowering season has ended. Do this before the seed sets, otherwise the plants will not bloom the following year, Cornell reports.
Tips and warnings
- If you want your foxglove to reseed, don't remove all the spikes at the end of the growing season. Instead, leave a few intact to allow the seeding process.
