Milkweed plants attract Monarch butterflies (which lay eggs on them and use milkweed sap as a food source) and other butterflies. If you'd love to attract more butterflies to your yard, this is the perfect plant. Many milkweed plants also produce pretty blooms in shades of orange, red and yellow and, therefore, are an attractive addition to your flower garden. Buying milkweed is neither difficult nor expensive.
Call your local garden centers. Some might keep milkweed in stock, although milkweed is not the most common type of plant sold. If you can find a store nearby that sells these you'll have two advantages: you will be able to look at the plants before you buy them, and you won't have to pay for shipping.
Purchase only milkweed plants that have not been sprayed with pesticides--pesticides may hurt butterflies and their larvae when they feed on the milkweed. If you are ordering the plants online and the website hasn't specified that the plants are pesticide free, email or call the company to inquire.
Buy plants close to springtime planting time for your region--some mail-order sellers won't sell or ship these plants in the winter anyway. If you order the plants online, how long it takes to ship the plants depends on the company; but you should allow two weeks. In other words, if you expect temperatures to be above freezing and getting warmer (the ground should not be thawed) soon, go ahead and buy the milkweed plants.
Have your credit card ready if you are ordering milkweed plants online. Few companies except mail-in personal checks for online orders.
Keep a copy of your receipt or your order confirmation number in an easy-to-remember place if you order milkweed plants online. This way, if anything goes wrong with your order, you won't have to hunt down the order information.
