Different Types of Milkweed
With monarch butterfly populations having dropped more than 90% in the last twenty years because of a loss of host plants, growing different milkweed plants is very important for the future of monarchs. Milkweed plants are the monarch butterfly’s only host plant. In midsummer, female monarch butterflies visit milkweed to drink its nectar and lay eggs. When these eggs hatch into tiny monarch caterpillars, they immediately begin to feed on the leaves of their milkweed host. After a couple weeks of feeding, a monarch caterpillar will seek out a safe place to form its chrysalis, where it will become a butterfly. With over 100 native species of milkweed plants in the United States, almost anyone can grow varieties of milkweed in their area. Many types of milkweed are specific to certain regions of the country.
The Northeast Region runs down through the center of North Dakota through Kansas, then east through Virginia and includes all states north of this. The Southeastern Region runs from Arkansas through North Carolina, including all states south of this through Florida. The South Central Region includes only Texas and Oklahoma. The Western Region includes all western states except for California and Arizona, which are both considered individual regions.
