• Foothill Penstemon, vivid and bright

    It’s California Native Plant Week and I’m profiling a different California native each day that is on my particular wish list. If you live in an area considered Mediterranean, you’ll be able to grow these, too. Today’s plant is Foothill Penstemon.

    Maybe because blue is a favorite color, maybe because I had not grown penstemon much in the past and maybe because it is a penstemon first seen and purchased at a favorite nursery, I fell hard for Foothill penstemon, Penstemon laetus, also called Mountain blue penstemon or Gay Penstemon.

    The genus, Penstemon, or Beard-tongue, is a common garden perennial, offered in so many colors and cultivars, but in California the native penstemons are nearly as varied. Penstemons normally have one large, sterile, furry stamen that pokes out to attract pollinators to the other four smaller fertile stamens (the name Penstemon means “Five Stamens”). “Laetus” means “bright” or “vivid”.

    Native to North America and East Asia, most penstemons are herbaceous perennials with flowers like snapdragons or sage but with an open mouth and fuzzy tongue that gives it its common name. All are suited to the wild Sierra Foothill garden, hardy from 0-10 F, unfazed by heat, overlooked by deer and drought tolerant. These are herbaceous perennials so most die to the ground, or nearly, in my garden.

     Foothill penstemon, as Intermountain Nursery calls it, is the loveliest color of iridescent blue-lavender. It’s found mostly in the Sierra Nevada foothills, stretching from one end of California to the other. It has a relatively broad and bushy habit with airy narrow-leaved foliage growing from a woody base, about 18 inches tall and takes some time to establish when transplanted.  The wait is worth it for it will bloom every May and June and will self seed to form larger colonies that will brighten a grassy area beginning to brown in late Spring’s heat.

    Mine were planted in 2006 from gallon containers on a clay bank and took four years to establish, the soil being the reason possibly. They have a ½ gal per hour dripper to them for late July and August or when we travel. I still feel they are less than robust, so will keep watering until they do. I’d also like to start another three plants in different soil conditions to see if they’d establish faster and easier. I consider the Foothill penstemon one of the prettiest native plants I’ve come across and my goal is to photograph it better (with focus this time) this June. This Spring, I was delighted to discover two or three seedlings near the parent plants and another goal is to grow and propagate more in several places in the garden.

    Spelling Penstemon:
    First, you have to learn to spell it.  There are no ‘A’s in penstemon, and I must have a block or something, but I have to think every time I type the name. Can anyone acknowledge me here?  There’s hope. Did you know you can add a new spelling to your Word dictionary?

      Hi Sue!

      I’ve been a bit scarce this past week or so, but I’m trying to catch up now. My own life is going to be ‘on hold’ for quite some time as we are raising two rescue pups. With our rainy season almost upon us, I want to have these two ‘potty-trained’ as soon as possible and so it’s a full time job.

      I am hugely partial to blue flowers in the garden, too,and absolutely love penstemons. I only have deep red and cerise ones so will make a point of looking out for blue ones.
      Yours are truly gorgeous (and I’m envious!)

      I hope you’re having an enjoyable and peaceful Easter weekend.

      Hugs,
      Des xo

      Hi Donna and Desiree, I love blue too, especially this one. Mint family …should be easy to grow in all its varieties.

      Hi Sue,

      I’m laughing. I found your site by typing “how do you spell penstemon” into Google. I know how to spell it, dammit, but then every time the red squiggle line shows up and I lose confidence. In my case it’s a question of how many Ms. Thanks for the tip on the dictionary. And your lovely site.
