One of my favorite blogs is The Common Milkweed. Steve & Jen are a couple of serious naturalists who practically live off the land and walk the talk. They also know more about milkweeds than anyone else I know. They’re very milkweed-savvy.
The Common Milkweed is a native plant, but considered invasive by many. It is very successful and seems to grow about anywhere. It is a great food plant for many insects. Just look at one closely and you will see all sorts of critters crawling on it, most famously the Monarch butterfly caterpillar. The plant is quite attractive all year long.
