Hoarhound-Marrubium vulgare

This non-native plant that often grows in disturbed areas is hoarhound (Marrubium vulgare), a member of the mint family (Lamiaceae). It has square stems and opposite leaves. It is native to Europe, Asia, and northern Africa and brought over to the U.S. as a garden plant with various medicinal properties. However, it escaped gardens and now grows out in the wild.
The small white flowers are followed by burs with hooks that can catch on anything that brushes up against them.

This spreading bush with attractive leaves and whitish-pinkish flowers is wax currant (Ribes cereum), a member of the Goosefoot Family (Grossulariaceae). Later in the season, small berries appear that can be used to make jelly. Generally this bush grows from 6,000-9,000 feet in our area, but I found it next to a lake at 10,230 feet.

Here you can see the fan-shaped leaves and the flowers in clusters.
