Foxglove (Digitalis purpurea) is a plant that captivates gardeners, herbalists, and nature enthusiasts alike with its striking flowers and intriguing history. But there’s more to this plant than meets the eye. In this article, we’ll explore seven surprising facts about foxglove that might change the way you view this beautiful yet dangerous plant. Whether you’re a gardener, a health-conscious individual, or a nature lover, something is fascinating about Foxglove facts for you to discover.
Native to Europe but widely cultivated across North America, foxglove is easily recognized by its tall spires of tubular flowers in shades of purple, pink, or white. The plant thrives in acidic soils and grows best in environments with moisture and filtered sunlight, often found along woodland edges, roadside verges, heathlands, and even gardens and hedgerows. In the UK, foxgloves are typically biennial or perennial, blooming from June to September.

While foxglove’s beauty is undeniable, it’s important to remember that it’s a plant that demands respect. Foxglove has long been associated with both medicinal uses and poisonous properties—the entire plant is toxic when consumed in large quantities. However, its medicinal role in heart disease treatment is one of the reasons it remains so significant. But this is just the beginning of what makes foxglove so fascinating.
7 Foxglove Facts
1. Foxglove Has Medicinal Uses—If Used Correctly
Did you know that foxglove has been used for centuries in medicine? While it’s true that the plant contains toxic compounds like digitalis and digoxin, these substances are the foundation of one of the most important medications used to treat heart conditions today.
Foxglove’s active ingredients have been used to treat heart failure, arrhythmias, and other heart-related diseases. Digitalis, extracted from the plant, helps strengthen heart contractions, improving the heart’s ability to pump blood.
However, it’s critical that only pharmaceutical preparations of digitalis be used, as consuming the raw plant can result in poisoning.
2. It Can Be Deadly If Consumed Incorrectly
Foxglove may be used to treat heart conditions, but it is extremely dangerous if consumed inappropriately [1]. Ingesting even a small amount of the plant can lead to severe poisoning.
Symptoms of foxglove poisoning include nausea, vomiting, diarrhea, confusion, and irregular heartbeats. In extreme cases, it can be fatal.
Always be cautious when handling foxglove, especially if you have children or pets.
3. Foxglove Flowers Are Not Just Beautiful, They’re Also Functional

While the flowers are undoubtedly beautiful, they’re not just for show. The tubular shape of foxglove flowers is designed to attract pollinators, especially bees. The plant relies on these pollinators to spread its seeds, ensuring the survival of the species.
-
Pollination: Bees and other insects love the nectar-rich flowers of the foxglove, and they’re drawn to the plant’s tubular shape, which suits their long tongues. This makes foxglove a great addition to any garden that seeks to support local wildlife.

4. It’s One of the Most Poisonous Plants in North America
While many beautiful plants are toxic, foxglove is one of the deadliest. All parts of the plant contain toxins, which can lead to serious health problems if ingested.
-
Historical Use: Despite its toxicity, it has been used in herbal medicine for centuries, though only under the supervision of a knowledgeable healer. Modern pharmaceutical methods have allowed us to safely isolate the plant’s active ingredients, but wild foxglove should never be consumed.
5. Foxglove Was Once Used as a Charm to Ward Off Evil Spirits
In addition to its medicinal and toxic uses, foxglove also has a place in folklore. Many ancient cultures believed that foxglove had the power to ward off evil spirits.
-
Cultural Significance: In European folklore, foxglove was sometimes hung in doorways to protect homes from witches and spirits. Its bell-shaped flowers were considered to be the plant’s protective charm.
6. Foxgloves Tall
One of the standout features of the foxglove plant is its impressive height. This plant can grow anywhere from 2 to 5 feet tall, depending on the variety and growing conditions.
Foxglove has a grayish, hairy stem that can grow between 20 to 59 inches tall, adding to its striking presence in the garden. The plant’s tall, spire-like flowers make it a showstopper in any landscape, whether it’s planted in beds or as a backdrop to shorter flowers.
Some dwarf varieties of foxglove, such as Digitalis purpurea ‘Pam’s Choice’ or Digitalis ‘Sutton’s Apricot’, tend to stay on the shorter side, reaching heights of about 2 to 3 feet. These shorter types are perfect for gardeners with smaller spaces or those looking to add a burst of color without overwhelming their flower beds.
On the other hand, the more common foxglove species, such as the classic Digitalis purpurea, can reach heights of 4 to 5 feet. These towering plants create a dramatic statement in any garden, with their long spires of colorful flowers reaching up to the sky and drawing attention from afar.
7. Foxglove Plays a Role in Ecosystem Health
Beyond its aesthetic and medicinal value, foxglove plays an important role in maintaining the health of the ecosystems it inhabits.
-
Wildlife Support: As mentioned earlier, its flowers provide nectar for pollinators, which helps support the local insect population. In turn, this benefits other wildlife that relies on insects for food.
Health Benefits and Risks of Foxglove

Foxglove is a double-edged sword. While it has been used to treat serious heart conditions, the risks associated with it are significant. Here’s a closer look at the health benefits and risks of foxglove:
Medicinal Properties of Foxglove
As mentioned, foxglove’s active ingredients, such as digitalis and digoxin, are used in the treatment of heart failure and arrhythmias. These substances work by regulating heart rhythms and improving the heart’s efficiency in pumping blood.
-
Heart Health: It’s crucial, however, that only properly prepared doses of these medications are used under the guidance of a healthcare professional.
The Dangers of Foxglove Poisoning
While the medicinal benefits are clear, overdosing on foxglove can be deadly. Digitalis, if taken in excessive amounts, can cause poisoning that disrupts heart rhythms, potentially leading to cardiac arrest.
-
Be Cautious: If you’re handling foxglove or thinking about using it for medicinal purposes, it’s essential to consult with a doctor first.
