Brugmansia, known by some sinister common names such as Angel’s Trumpet and Devil’s Breath, embodies high drama in the plant world. With its foot-long, pendulous blooms that sway in the evening breeze and its intoxicating fragrance, it lures both humans and night-flying pollinators from mid-summer to late October. Its scent is so powerful that it has found a place in commercial perfumery. The color palette of its flowers is equally alluring, with blooms ranging from pristine whites to buff, peachy pinks, pale golds, muted oranges, and salmon. In full bloom, mature specimens put on a spectacular display, becoming the star of the garden late in the season when most things have stopped blooming.  However, these seductive flowers come wrapped in folklore, magic, and an unmistakable aura of danger.

Plant of the Night

The life cycle of Brugmansia’s flowers follows the rhythm of day and night. As the sun begins to set, its trumpet-shaped blooms unfurl, releasing a sweet and heady fragrance that fills the evening air. This gives Brugmansia another common name, the “Moonflower.” During the day, its flowers hang like sleeping bats, with their petals tightly closed, and no scent lingers. The timing of their bloom and fragrance production is under circadian control, which works well if you enjoy throwing cocktail or dinner parties on the back deck on a sultry autumn evening. It is also a welcome highlight on Halloween as trick-or-treaters come to your door and your orange Brugmansia is in full bloom. No other decoration needed!

Cloaked Pollinators

When doing research for this article, I found conflicting information on pollinators. Most sources suggest something that flies around at night since that is when flowers open. Others say hummingbirds. Maybe all of the above depending on the species and geographical location, but it’s clear that we still don’t really know. A publication from the University of South Florida suggests that the dominant pollinators of B. suaveolens are most likely bats and night-flying moths. Butterflies also seem to play a role where B. suaveolens is a larval source for the butterfly Placidula euryanassa. Studies show that the caterpillars can consume the toxins without harm, storing the poisonous alkaloids in their bodies to ward off predators later in their life cycle.

The Weedy Side of Brugmansia

While Brugmansia’s flowers are dramatic, the plant itself can look weedy and unkempt when not in bloom. It is hardy in USDA Zones 7–10 and grows quickly, often reaching heights of 15 to 35 feet. It works well as a background shrub or small tree in garden design. Although Brugmansia is said to prefer full sun, I’ve had more success growing it in partial shade in my Durham, NC (Zone 8a) garden. Like most members of its family, Solanaceae, it likes water, which could be a reason to grow it in some shade. This plant only emerges when the soil warms, so it works well to plant spring and early summer-blooming flowers in front of it until it takes center stage in late summer through autumn.

Growing Brugmansia in My Garden

I first encountered Brugmansia on the roadsides of subtropical Brazil, growing under larger tree canopies. Its large, bell-shaped flowers in shades of white, pink, and orange captivated me instantly. Later, I saw it thriving in northern California gardens and decided to try it in my own garden in Durham, NC.

That was years ago when Durham, NC, was considered USDA Zone 7. Brugmansia is borderline hardy in Zone 7, making each winter a gamble. I eventually started planting the rootstock deeply, below the frost line, to protect it from frost. This delayed its emergence even more, but when the plant finally came up in late summer, it rewarded me with a spectacular display.

Today, I have two dependable Brugmansia plants—a double white and a single orange—that return each year. Interestingly, the orange one blooms earlier, just in time to avoid the first frost, which can otherwise cut short the flowering season. The white one is hit or miss depending on weather conditions. I hear the same from others that have these plants growing in Durham, NC. Apparently the flowers need a very long growing season to fully open.

A Freaky Family

Brugmansia is a member of the Solanaceae family. This family blurs the lines between food, poison, and magic, with plants like Solanum lycopersicum (tomato), Capsicum (pepper), Solanum tuberosum (potato), Nicotiana (tobacco), Atropa belladonna (belladonna), and Hyoscyamus niger (henbane).
The family brews a veritable chemical cauldron of both desirable and deadly compounds referred to as tropane alkaloids. These include nicotine (Nicotiana), solanine (Solanum), capsaicin (Capsicum), atropine (Atropa), scopolamine (Datura), and hyoscyamine (Hyoscyamus)—chemicals that have been used as healing drugs in small doses, misunderstood or abused as addictive substances, and used as pesticides and warfare agents (e.g., sarin) in toxic doses.

Dangerous Beauty

Every part of Brugmansia is toxic. It contains dangerous alkaloids, like scopolamine, which can induce hallucinations and, in larger doses, have fatal effects. These alkaloids have historically been used in rituals to induce altered states of consciousness or to connect with the divine.

Shrouded in Shadowy Lore

Brugmansia is steeped in mystery and legend. Its downward-pointing flowers are said to serve as a bridge to the afterlife, with folklore suggesting they can draw spirits from graves. In a haunting twist, legend has it that sleeping under a Brugmansia plant may summon angels to claim your soul before you wake. The fragrance is reputedly narcotic. How true any of the stories are is questionable but perhaps telling. Embedded in the legends are nuggets of truth around the toxicity of the plants.

Brugmansia, an intoxicating beauty with folkloric connections, makes it a fitting plant for the Halloween season. Its nocturnal habits, eerie association with spirits, and dramatic blooms bring mystery and enchantment to any garden, especially under the October moon. However, don’t forget the danger of its deadly properties. Inhale its perfume, but keep your distance—it can kill you.

Poison Ivy: Get it Before it Gets You!

By Jane Malec, EMGV

Few things scare me in the garden. Copperheads, brown recluse spiders and wasp nests come to mind. Now, poison ivy has climbed nearly to the top. Sure, you most likely won’t die from a poison ivy rash, but you may want to at a given point.

I had an encounter, unknowingly, with this vine and the rash is just abating after nearly three weeks. I have been on steroids and antibiotics and will end up with some scars. I did nothing after coming in contact with the poison ivy which made things much worse.

Recognizing Poison Ivy
So, we are going to pretend that this gardener surveyed her yard adequately for all poisonous vines before cutting in new beds. Let’s look at recognizing these plants and how to get them out of your yard. Keep in mind, in areas that you do not plan to garden, compost, or sit and enjoy the scenery, leave the plants alone. Nature has a purpose even for these devils.

Here’s an interactive QUIZ to help you identify poison ivy.

As a review, poison ivy is a very prolific perennial vine/shrub with the distinctive three leaves. It can be found nearly everywhere in the landscape in both disturbed and undisturbed areas such as roadsides, hiking trails and wooded lots. This woody perennial spreads by runners and will grow in all types of soils. Also, there are many species of birds that eat the berries and pass them directly through their systems which get deposited in other areas to yet be eaten by different types of animals. They in turn redeposit the seeds in your garden. Interestingly, the animals who eat the seeds do not have an allergic reaction to the volatile oils. Lucky them! This process, together with the runners, greatly increases the likelihood that you will have a poisonous creeper of some kind in your yard.

Control with an Herbicide Containing Triclopyr
Armed with this information and knowing the result of an encounter with the plant, being proactive is the best measure. Every article I read online at 2:30 a.m. when the itching kept me from sleeping started out with “the easiest way to avoid contact is to be aware and get it out of your environment.” Not what I wanted to read at that point, but it’s the truth. The options for control really boil down to utilizing an herbicide containing triclopyr which is a woody brush killer. Yanking, pulling and digging are time consuming, risky, and ultimately not effective.

The herbicide should be applied directly to the leaves of the plant. Spray your target not the area. Spring and summer are excellent times to control poison ivy because the plants are actively growing so the herbicide will travel through the plant. Weather also plays a role. Temperatures should be in the range of 60-85 degrees F and avoid windy days. Check the label for dry times to make sure effectiveness is not lost during a rain shower.

Oftentimes, this is not a once-and-done project. You may need to spray again, but wait two weeks or more to give the first application time to work. Look for new growth when you are circling back and, for the best results, spray open leaves only. Be vigilant in your search as resprouting may occur several months later. Once the fall color appears on these plants, do not apply any more herbicide. Wait until spring when the leaves open up and the plants are growing.

Keep in mind that it may take more than one season to rid an area of poison ivy or oak. Check areas carefully and never be over confident. Remember our winged friends are spreading the berries!

Beware of Virginia Creeper
Poison ivy or oak are not the only plants that can cause problems. A very small number of people, myself included, have reactions to Virginia Creeper. Although not as allergic as poison ivy,  raphides, the sap of this vine can cause rashes and blisters if the skin is punctured.

Virginia Creeper is a popular native ground cover or climbing vine due in part to its beautiful fall color and blue-black berries. It is often planted by gardeners and spreads quickly once established. Most people are unaware of potential problems and don’t take precautions with a five-leaf plant as we do with the dreaded three leaves.  If you have had a severe reaction to other poisonous plants, you would be well served to avoid Virginia Creeper.  Follow the same steps previously outlined for poison ivy control if you wish to remove this plant from your environment.

Finally, here are some important reminders:

  • As with any treatment product, read the label carefully.  Avoid the “this is good enough” method. Also, wear protective clothing.
  • Be very careful cutting down poison ivy plants as all parts of them are poisonous including a dead plant. Do not compost any parts of them; Carefully trash them.
  • Never burn any part of these plants. The smoke and ash can cause a rash and inhaling them can win you a painful trip to the emergency room.

I cannot warn you enough … do not be over confident!
