Stories from the Garden: The Monarch!
Nicky was surprised at how good these leaves were! He had been skeptical when his brother Alan tried to convince him to take a bite. They had both grown up eating the plant where they were born, and he was used to narrow, thin milkweed leaves. This new milkweed was so wide it was like eating ten of the the other leaves at once!
The taste was just as good, and he could really get a rythm going as he munched back and forth across the broad expanse. At this rate, he would be an adult butterfly in no time!

Note: Milkweed is the host plant for the monarch butterfly, meaning it is the only plant the caterpillars can eat. There are various species of native milkweeds for the Sacramento region, including Showy Milkweed (Asclepias speciosa), Narrow Leaf Milkweed (Asclepias fascicularis), Heart Leaf Milkweed (Asclepias cordifolia), and Woollypod Milkweed (Asclepias eriocarpa). Non-native milkweeds have been associated with increased disease risk for monarchs in California due to their ability to remain green year-round, which can promote the buildup and transmission of the protozoan parasite Ophryocystis elektroscirrha (often called OE), and should be avoided when possible. If already planted, cutting them back periodically can help reduce disease buildup.
