Velvet Leaf

This is not poisonous
What is Velvet Leaf?
This pesky plant is a member of the mallow family, which also includes desirable plants such as hibiscus, hollyhock and cotton. An upright annual weed that can reach heights of 7 feet, velvetleaf is named for the huge, heart-shaped leaves, which are covered with fine, velvety hair. The thick stems are also covered with hair. Clusters of small, five-petaled flowers appear in late summer. Controlling Velvetleaf Plants Velvetleaf weed control is a long-term project because one plant creates thousands of seeds, which remain viable in the soil for an incredible 50 to 60 years. Cultivation of the soil may seem like a good solution, but it only brings seeds to the surface where they are able to germinate readily. However, it’s a good idea to mow the plants while they’re small to prevent them from going to seed. Rapid response is key, and eventually, you’ll gain the upper hand.
