Plant of the day: fennel

It tastes great in salads, but fennel (Foeniculum vulgare) is an unfortunate weed in California. It grows avidly along roadsides and in other disturbed places. This plant grows up to ten feet tall, with feathery leaves and yellow umbrella-shaped umbels of flowers.

The leaves and the seeds have a distinctive licorice flavor, which is likely why the plant came to the Americas in the first place. It’s been used as a spice and a medicinal plant for centuries, and is thought to have escaped into the wild time after time.

Fennel is an invasive species, and takes over areas by forming dense stands where nothing else can grow. This isn’t just because the plants are so numerous that there is no room for any others. They also exude chemicals that actually prevent their competitors from growing!
