PlantFiles: Common Milkweed
Asclepias syriaca

Common Milkweed Asclepias syriaca is native to Texas and other States.

A plant of pluses and minuses as others have described. Here in central MD, I rarely have seen any monarch action on my ten-plus year, healthy patch. I do always have milkweed bugs and often milkweed moths, which are interesting in their own right. The moth caterpillars clued me in on another type of milkweed that volunteered in my yard, as I saw them on it and figured it must be a close relative.

I feel in love with milkweeds after moving to Chicago and 'rescued' one from being dug out by landscapers. Well, that one root is now popping up all over my yard, even in a bed of Butterfly Weeds (which even thought they are also Asclepias don't seem to be as attractive to Monarchs as host plants).

Despite the fact that is not well bahaved, I love this plant. Last year we raised and released 3 Monarchs, and my son and I have already brought in 4 Monarch eggs to raise this year. And the smell of the flowers is heavenly!

Shortly after the milkweeds came, the milkweed bugs followed. Maybe that's why we haven't seen any pupae on the plants themselves.

I've read that the young pods can be boiled and eaten in an emergency.

I like the look of Milkweed, I like the scent of its flowers, I like the butterflies it draws, but I don't like its invasiveness. I have a small yard, so have to have plants that are a little better behaved. Maybe if I had it in an area with poorer soil it would be better.

This plant grows wild all over the Piedmont area of Virginia & my fields are full of it. Although I don't find the plant itself or its flowers particularly attractive, I do like the seedpods, which make lovely additions to fall & winter dried arrangements & crafts.

Although it is well-known as a food source for the Monarch Butterfly, I have yet to see any Monarch larvae on any of the plants around here, although the butterflies themselves are frequently spotted from late summer until frost. As a "butterfly " plant, I don't see even 1/10th of the number of butterflies that I do on other wild attracters such as Butterfly Weed & Thistle.

It is somewhat toxic to livestock, but is not attractive to them so is rarely eaten except in desperation. Still - I remove it regularly from all pasture areas. It can come up as a pest in my vegetable garden, but is relatively easy to pull from moist soil.

All in all, I'm rather "neutral" on it as a garden plant, although I do understand it's importance in the "wild" scheme of things.

I haven't grown this in a garden, but from living in Rhode Island, I know it well. It seems to be a prolific spreader and has seedpods full of "milkweed silk" and seeds. Grows most often mixed in with beach plum and other seaside plants.

This plant is definintely a HUGE attraction for adult Monarchs. It's important to also note that it is not only a preferred host plant, but Asclepias are the ONLY host plant for Monarch caterpillars. The Monarch larvae/caterpillars cannot survive without Asclepias as a food source.

I looooove asclepias syriaca...... it is not the best garden plant because it will take its share of space...... but if you plant it elsewhere...... contain it etc. it is a great plant...... I think it's pretty and the smell is........ oooooohhhhh ...... heavenly..... it's also a host for monarch butterflies...... one of the most important hosta and the monarchs are loosing their habitat...... find a place for this plant in your garden...... you won't be dissapointed!!!!! Kids also love the fluffy seed pods and some people use the seedpods in crafts although I like poppies for this better ....... the smell is of lilacs and hyacinths....... very strong and wafts on a summer evening :)

No matter how much this plant spreads, it can't get on my bad side. I think the flowers from common milkweed are the most becomming of all the cultivated and other wild milkweed.

The plant yeilds large 4" round clusters of mauve flowers with broad leaves and thick stems.

The negative is that the stalks often fall over if the season was overly rainy. Also, this plant spreads by a vigourous underground root system and will come up all over the place if not controlled. I found that cutting the plants down to the ground continously (whenever they come back up) and disturbing the root system by digging up as much of it as possible elimates unwanted plants.

Common milkweed does not seem to be preferred over other milkweeds by monarchs and other butterflies. They tend to pass over the common and go for swamp milkweed which has flat flower clusters and tender leaves.

Edited to note that this milkweed is extremely targeted by milkweed bugs and beetles due to it's thick stems and broad leaves.

I have one bed that is devoted to my milkweeds. It's in my front yard. I love the blooms. You can smell them all over the front yard. But the plants are special to me because of the Monarch Butterflies. Every year I wait for them to lay thier eggs on my plants and hunt daily for the caterpillars to emerge. I bring them in the house and raise them until they become butterflies and then release them. Last summer I raised and released 14 monarchs. I supply the 1st grade classes at the school where I teach with caterpillars to raise each year also.

This milkweed is common in New England and grows wild along the roadsides and in open fields. Although the flower clusters are attractive, IMHO this is not a good choice for a garden plant. The deep fleshy roots will invade surounding plants and they're nearly impossible to dig out. I've dug 3 feet down trying irradicate it from some of my beds and it still pops back up like it was never disturbed.

On a positive note, it's a host plant to monarch butterflies. Adults love the flowers and the caterillars feed on the foliage. Plant it in an out of the way area where it can compete with grasses and weeds. It's tough enough to stand it's own ground and you'll be able to enjoy the butterflies it attracts.
