Gardeners' Notes:

Positive Siirenias On Feb 10, 2015, Siirenias from Oak Park, CA (Zone 9b) wrote:

This plant is cute, but can be a monster in perpetually moist spots. It will spread eagerly after first flowering, as far as it can find water. It will also readily seed out and germinate to quickly take over other wet spots with grass-green to dark green leaves and bright yellow flowers.

However, the whole plant is edible and the attractive yellow flowers bring in mason and carpenter bees. Don't be afraid to rip it out of where you don't want it.

This is a common wildflower of roadside ditches and moist areas in my area (Linn County, OR), and I have successrully transplanted it from the wild to my raised flower bed where it bloomed continuously throught June and July. It's common name is Seep-spring Monkeyflower

In Michigan, it's sold as an annual. However, some of mine reseeded from last year.
It formed a bright carpet when planted after the daffodils finished blooming.

Neutral eje On Jul 24, 2002, eje from San Francisco, CA (Zone 10a) wrote:

Like the large snap-dragon-style flowers of this west coast native a lot; however, the bloom time is not long and it's a little weedy. After blooming it sends out runner-like shoots and also self seeds. Probably could be invasive, if conditions permitted (like in a bog garden). Good in a native plant garden. Probably not appropriate for anything more formal.
