Gardeners' Notes:

As far as Goldenrod goes, this is about the best species for a garden. It's very showy. Even without the flowers, the stem and leaves are attractive. They can self seed quite a bit, so simply remove seedheads to keep things under control. Highly recommended for helping Monarchs out during the early stages of their migration back to Mexico.

This is an amazingly cool native plant. It has beautiful yellow flowers in massive amounts and an even better point is that the native birds, especially goldfinches and our wintering white throated sparrows, love the seeds.
However, it is a bit of a garden thug. I removed all but one and must pull seedlings frequently. But they are not difficult to remove and they do not spread underground. For me, they are worth the extra effort. It is so rewarding to see the native birds eat the seeds from mother nature's feeders. They are tall, and if well-watered, need support.

A beautiful, tall, heat resistant plant with vivacious lemon yellow flowers that blooms in late summer when other plants are beginning to decline. It attracts Skippers and other butterflies in this part of eastern Kansas on the outskirts of Kansas City, but needs to be staked in my garden's rich, clay soil to prevent drooping. It is very drought tolerant, and withstands our winters as well.
