Mimulus

I have the wild one - Monkeyflower - its yellow. Grows like a weed, self seeds freely.
Can't remember how to link a post on here but photos at
Garden And Gossip Forums  Flowers and Ornamentals  All about Flowers and Ornamentals  Can you identify this flower and a leaf?

I remember it well.  Mine are lower growing than yours, but when they're grown up they may be bigger.  I have high hopes of having lots next year.
