Is there an annual milkweed?

ANNUAL MILKWEED: Tropical Milkweed (Asclepia Curassavica) – this annual milkweed features showy red and yellow flowers and is preferred by egg-laying female monarchs to the other milkweeds when given a choice. Grows fast and easy from seed and flowers all summer long.

Does milkweed grow back every year?

These native milkweed are perennials, meaning they come back year after year. Their aerial parts (flower, leaves, stem) die back but their rootstock remains alive throughout the winter. Cut back milkweed stalks in the late fall or winter, after they have produced seed pods and these seeds have had time to mature.

Is milkweed a summer annual?

Common milkweed (Asclepias syriaca) is a perennial plant that can be found in a wide range of habitats including roadsides, fields, and gardens. It is native to North America and reproduces primarily from seed.

Why is milkweed a problem?

Tropical milkweed becomes a problem when planted in temperate areas where it does not die back in winter. A protozoan parasite of monarch butterflies, Ophryocystis elektroscirrha or OE for short, can travel with monarchs visiting the plants and become deposited on leaves.

Will milkweed spread?

Common Milkweed Can Spread Aggressively Anyone in its native range (zones 3 to 8) with space for a wildflower garden can consider common milkweed. But gardeners should be aware that this species is considered very aggressive. It spreads not only by seed but by underground rhizome, and can be very difficult to control.

Why do farmers not like milkweed?

Milkweed has a reputation for encroaching on cropland where it can compete with crops for soil and light. The plant can also create a nuisance on ranchlands, as cattle can be poisoned when poor foraging conditions lead hungry cows to milkweed-concentrated areas as a last resort.

Where should you not plant milkweed?

It is not recommended to plant milkweed within 10 miles of the coast in central and northern California where milkweed did not occur historically. Instead, plant a variety of flowers native to your region that provide nectar from early spring through fall to support monarchs and other pollinators.

Can I just scatter milkweed seeds?

You can sow milkweed seeds by scattering them on the soil surface 1/4-1/2 inch apart, and then cover them with about 1/4 inch of additional soil. Water the area frequently after planting until plants become established. Many species need to be vernalized (cold treated) before planting.

Should I cut down milkweed in the fall?

It is recommended to prune the milkweed stalks to about 6 inches in height during the fall and winter months to discourage monarchs from establishing winter-breeding colonies. Cutting back the milkweed will also help to eliminate OE spores that may be present on the plant.

Will milkweed reseed itself?

If you've ever seen milkweed in action in the fall, it's easy to understand. Large seed pods open up and self seed readily, spreading this native wildflower's seeds each season.

Should I plant milkweed in my yard?

If you want monarch butterflies to visit your garden this fall and spring, planting milkweed in your landscape is a must! Not only is milkweed a great nectar source for thirsty pollinators, it is also THE ONLY host plant that monarch butterflies lay their eggs upon.

Plants in this genus flower during the summer, set seed in the fall, and die back in winter. With proper care, they'll be ready to sprout again the following spring from an underground network of creeping roots. Milkweed also spreads easily from seed.

What happens if you touch milkweed?

All parts of the plant contain toxic cardiac glycosides, which can cause nausea, diarrhea, weakness, and confusion in small amounts, and seizures, heart rhythm changes, respiratory paralysis, and even death in large amounts. Milkweed can also irritate the skin and eyes if touched.

What are the benefits of growing milkweed?

Native milkweed plants are vital to support the monarch butterfly population in North America. Farmers and gardeners are starting to plant more of it because it attracts beneficial insects that prey on pests like aphids, leafhoppers, thrips and even stink bugs.

Why would you want milkweed?

Milkweeds are the required host plants for monarch butterfly caterpillars (female monarchs lay their eggs on milkweeds) and their flowers provide nectar for bees, butterflies, and other beneficial insects. By planting milkweed, you can provide habitat for monarchs and also attract and support pollinators.

Will milkweed choke out other plants?

Depending on who you ask, this could be a good or bad thing – the pollinators sure love it, but some (though not all) asclepias can quickly choke other plants out. Asclepias is also known as Milkweed.

What month do you plant milkweed?

Ideally, the best time to plant milkweed seeds is in the fall so the cold temperatures and moisture that come with winter stimulate germination. You can also plant milkweed in the springtime.
