PLAN AHEAD FOR MONARCHS
Monarch caterpillars only eat milkweed plus a female Monarch butterfly won't lay her eggs on any other plant. By planting milkweed in your garden, you can help sustain monarch populations! There are 200 species of milkweed found around the world. Approximately 30 of those are found in Texas. The two most common native milkweed species that grow in the DFW area are green milkweed (Asclepius viridis) and antelope horns milkweed (Asclepius asperula).
Although tropical milkweed (Asclepias curassavica) is often available at local stores, there are a number of problems associated with it that are detrimental to the health of monarchs. .
Fall is the best time for planting milkweed seeds. The seeds won't germinate until spring because they require natural freezing and thawing to soften the seed coat so that the embryo plant can grow. This process stops seedlings from emerging in the fall and being killed by winter cold. You can plant the seeds from September 1 up until the soil freezes. They will come up in spring when conditions are right for them to grow. Before planting, you should consider where you would like for the plants to grow. Common milkweed plants can reach about five feet in height. For some varieties of milkweed the flowers may not appear for the first few years but monarch butterflies will use the plant to lay eggs and the caterpillars will complete their life cycle feasting off the leaves.
