Gardeners' Notes:

Positive sltxgardener On Feb 10, 2006, sltxgardener from Sugar Land, TX wrote:

This plant is the larval host plant for the monarch butterfly and is so popular with the hungry, little critters that you'll want to plant it behind another plant that doesn't get eaten down to the bare stems. Keep it accessible, though, because you'll love watching the beautiful monarch caterpillars munching away. When one "litter" disappears, look around your garden for the glittering green chrysalises. Our palms were a very popular spot with successive generations last summer and fall. What a joy to share our garden with such beautiful creatures!

I bought a packet of these because they were good for the butterflies. They have grown well and are great plants but somehow I felt I should have seen more butterflies than what I have. I still like them anyway and will grow them again next year.
