The Backyard With Possibly Life-Saving Venom

You may not know this, but the foxglove plant is highly toxic. However, the plant's toxicity is countered by the same plant being the source of some chemicals used for saving lives in hospitals. This plant's leaves contain the chemical digitalis, which is used to make digoxin, a drug that millions of heart failure patients have to take to keep their heart rhythms stable.

The plant has cardiac glycosides, a type of chemical that affects the contractions of the heart muscle. In a medical setting, these can be life-saving when given in a controlled manner. However, when dosing occurs in a garden setting, it can be very dangerous as they can cause nausea, vomiting, diarrhea, and can even cause fatal heart arrhythmias. Additionally, some people may be affected by skin irritation from contact with the plant.

Over the past several centuries, this duality has inspired cultural references to the plant as \\"Dead Man's Bells,\\" \\"Witch's Gloves,\\" and \\"Fairy Fingers\\".

Walisischer Zauber alter und moderner Gärten

The Welsh people were aware of the importance of foxglove long before anyone understood cardiac glycosides. Flowers of the foxglove were crushed to produce a deep purple dye, which the Welsh people used to paint protective symbols on their doors and window sills.

Absolutely, the dye was toxic, and it's possible the dye's toxicity may have deterred some predators (though it probably wouldn’t have deterred supernatural ones). It is somewhat ironic that in the Welsh fairytale, there is a description of how fairies dwell in the bell-shaped flowers, and that if you disturb a foxglove plant, the fairy folk will get cross.

Foxglove can help us enjoy the cultural stories and also the benefits of the garden, including breathtaking vertical interest, support of pollinators, and natural pest deterrence as very few animals will browse on these toxic plants.

Foxglove: Simple to Cultivate and Stunning as Well

Most American gardeners can grow this plant as foxglove thrives in zones 4-9. Being a biennial plant, foxgloves have a two-year life cycle. In the first year, foxglove plants grow leaves, while in the second year, they grow stunning flowering spikes.

Foxtail can grow in partial shade but requires shade during the hotter parts of the day to prevent wilting. The soil must be rich in organic matter, well-drained, and moist. Additionally, in cooler areas, full sun conditions are fine. In hotter areas, foxtail will also thrive with afternoon shade as it prevents wilting. For optimal growth, foxtail should be spaced 12 to 18 inches apart. This is because foxtail will self-seed and create new colonies over time.

Do you want foxglove flowers every year? The secret is in their annual reseeding. While foxglove plants only live up to two seasons, having multiple generations gives you more blooms! In the spring, do new plantings, and let some plants go to seed.

Family-Safe Foxglove: Helpful safety measures

If you want to grow foxgloves, you don't have to avoid planting them due to having kids or pets. Keep the family safe while enjoying these gorgeous plants by doing the following:

While picking locations where foxglove will be planted, think of how accessible the area is. For example, the back border, cutting garden, and behind other plants would all be good options. Try not to plant them around play areas, vegetable gardens, or anywhere that may have little hands roaming about.

Think creatively about other barriers besides fences. Using low decorative edging, companion planting such as lavender or catmint, and using decorative plant markers can discourage casual contact while still enhancing the beauty of the garden.

Teaching children not to touch means the elimination strategy fails. Instead, it is more productive to teach children the “look but don’t touch” rule and the dangers of foxglove. Older children helping in the garden can and should be taught to respect the more dangerous plants.

Whether you are deadheading, transplanting, or disposing of old leaves, anytime you handle any part of the foxglove plant, be sure to wear gloves. Be sure to wash your hands after gardening. Dispose of foxglove debris outside of your compost to prevent the spread of contamination in your garden.

Pollinator Paradise Effect

Foxgloves have flowers that are made perfectly for bumblebees. These big and strong bees can push their way into the flower and reach the nectar. It’s amazing to see a large bumblebee dive into a flower and come out covered in pollen.

The benefits extend beyond just the bees. Hummingbirds are attracted to certain white and yellow varieties of the foxglove and can be seen getting nectar from them. The tall flower spikes of the foxglove also serve as rest stops for beneficial insects, such as lacewings and hover flies, who do pest control in the garden.

The time is perfect! Foxglove blooms in late spring and early summer when many pollinators are starting their colonies and establishing nectar needs. Each flowering spike on a fully grown foxglove has 20-80 blooms, so it could have dozens of spikes!

Different kinds of Foxglove apart from the Purple

While foxglove's typical purple flowers are stunning, there are more exciting varieties to discover. For truly unique spikes, look for 'Alba'. This variety has white spikes that stand out in the evening. And for an even softer touch to the garden, 'Apricot' displays peachy-pink blooms!

Another option is Digitalis grandiflora (large yellow foxglove), which typically is more perennial than biennial, and offers an alternative with buttery yellow flowers. Digitalis ferruginea (rusty foxglove) is another choice, with narrow spikes and small flowers that are rust colored and can be of architectural interest.

Although the toxicity levels of these alternatives differ, the same amount of care is required for each of them. The different visuals and care requirements warrant using all of these alternatives.

Paradoxes of Having a Garden

Foxglove reminds us of the contradictions we can embrace in both life and in the garden. It is a beautiful plant that is dangerous to us, but throughout history and folklore has attracted pollinators.

Foxgloves have a dual nature so to grow them you must appreciate both sides of it. You have to admire their beauty, but also, you have to acknowledge their possible danger. This kind of duality helps us to become better gardeners and more responsible with the plants we grow.

The first spikes of foxgloves emerging in spring will show you why for generations, gardeners have been prepared to risk it. Just make sure to watch from a safe distance.
