Attract Butterflies, Bees, And Birds with this Pollinator!

The Calotropis Gigantea is native to mostly tropical regions throughout Africa and Asia. Best grown in zones 11 and 12, it prefers to have full sun and is actually highly drought tolerant, so you don’t need to worry about watering your Giant Milkweed everyday.

This shrub tends to grow up to 15 feet total if left on its own, though it can be trimmed to some smaller sizes. What makes it a great hedge for your property or the edge of your garden is more than the green leaves and stems but actually the interesting flowers that grow seasonally.

The flowers on this plant, also called a Giant Milkweed, are actually waxy and come in light purple and white colors that are very unique. In fact, they’re even used in floral arrangements in some parts of the world because of the look and the fact that they last a long time.

Some use an extract from the flowers and the leaves for their hypoglycemic effects and some use them for funeral decorations. They’ve even been used for shrines to the Lord Shiva and the fibers have been used for things like rope, nets, sewing, stuffing and more. In all, there are numerous different purposes for his plant, however it’s important to be careful around it as well.

There have been some uses that were not as mundane or healthy, such as using it as an arrow poison because it can be toxic. For others, it’s an ideal medicine, having been used in Indian folk medicine for treating asthma and even liver diseases. Some have also treated arthritis, cancer, snake bites, nausea and vomiting, among others, but there is little research on these at this point.

The Calotropis Gigantea’s leaves make a the perfect place for caterpillars to pupate on. The giant milkweed makes a great attractant for butterflies to flock to in your garden as it is considered a butterfly magnet. Butterflies such as Monarch, Queen, and Soldier Butterflies tend to use the giant milkweed as a host plant. This lovely plant is also attractive to bees and birds as well and can be a great addition to your garden to attract those much need pollinators!

Why others chose this plant.

My family has always been into rearing monarchs and during migration season we often run into a milkweed shortage due to the massive quantity of monarchs coming though. I was ecstatic to see someone selling giant milkweed plants rather than seeds or cuttings that take months to grow. Can't wait to see how our caterpillars like it!

Butterfly gardeners!! This Giant Milkweed plant is a must for your Monarch Butterflies. You will love this plant.

Do you use pesticides when growing the Giant Milkweed shown for sale. My concern is that I want plants I purchase to be safe for Monarch larvae to eat.

Hi Karen, All our Milkweeds that we ship out directly are typically untreated. If we acquire them from one our partnered nurseries then there is a chance they were treated as they do all their plants when growing. Any kind of treatment however will filter through the plant within a few months. There has been no issue with this previously and it is completely safe for your Monarchs to enjoy! 🙂

Hi Joan,
Unfortunately, Giant Milkweed are cold hardy for USDA zones 10-11. But you can still enjoy them in colder zones as annuals by overwintering indoors!
