Even if you don't have appropriate space in your yard to plant native plants, you can still plant natives in pots, troughs and trays and place them along on a balcony, in a window trough or along the driveway to enjoy them during their bloom!

Here's one good plant to start with: Cardinal monkeyflower (Erythranthe cardinalis) which should be available at many native plant nurseries. I'm not able to get this to survive in the ground, but boy does it like to grow like crazy in pots! And it self sows its seeds into nearby pots, too. These are 2 gallon pots with saucers placed under them. I water them every several days (if needed) in cool weather, but they get watered every day in +85F or on warm windy days. I make sure to water from the base of the plant in the pot and then let water collect in the saucer until it is full.

In this image from my driveway, there are the usual crimson color-forms for the flowers, but there is also an orange-flowered one as well as a pink-flowered form. This species of monkeyflower seems to be able to form hybrids with both common monkeyflower (Erythranthe guttata) and Lewis' monkeyflower (Erythranthe lewisii) so one can get a variety of colors and flower and calyx shapes in the resulting offspring plants which grow either later in the year or during the next spring season.
