When spending your day outdoors, you never know what to expect. Especially in the spring and summer when poisonous plants such as poison ivy are most active (remember, hydrocortisone is an essential addition to your first aid kit!) But what happens if you forget your kit at home? Don’t panic! Look around for an orange, spotted, cornucopia-shaped flower—it might just save the day.
Growing anywhere from two to five feet tall, jewelweed is a natural remedy to poison ivy—if you can catch it quickly enough. To use its medicinal properties to prevent a rash, you must apply jewelweed to the infected areas before your immune system can recognize the urushiol oil (what causes the poison ivy rash). This varies by person but can take as little as 10 minutes.
Lucky for you, jewelweed is native to northern and eastern North America and can be found all throughout the Chesapeake Bay watershed. This plant thrives in moist, semi-shady areas, floodplain forests and around forested edges of marshes and bogs—the same areas where poison ivy grows.

If you fear you may have come in contact, here’s what you do:
Apart from their functionality, jewelweed is fun too! Commonly referred to as “touch-me-nots” and “poppers,” jewelweed seed pods are known to explode when one encounters them, releasing tiny, green seeds everywhere.
This feature is why jewelweed is considered a self-seeding plant. These plants do not require pollination to reproduce and instead form these seed pods on their own once matured. Jewelweed seedlings sprout in early spring and reach maximum size by August. Flowering begins around mid-summer and continues until the first frost.

With many invasive plants causing problems for native species, jewelweed is known to hold its own. When fighting for its favored habitat, this plant has successfully competed against some of North America’s most troublesome invasives like garlic mustard (Alliaria petiolata).
This collection of favorable traits makes jewelweed the perfect addition to any garden. Between its vibrant color and abundance of nectar, this plant attracts a variety of pollinators and wildlife like bees, butterflies and hummingbirds. Additionally, jewelweed flowers contain a sticky substance that can trap grubs, aphids and any other little pest that may disturb your garden.
The key to a thriving jewelweed plant is to make sure it is planted in a location that receives at least six hours of sunlight each day. While companion plants—such as lavender and sage—can help your garden flourish, planting them too closely to jewelweed could disrupt the plant’s growth. Finish it off with well-kept soil and a regular watering schedule and you will have jewelweed blooming in no time!
