and under Douglas Firs, Jeffrey or Ponderosa pines from near sea
level to 7000+' elevation. Prostrate Ceanothus is an
excellent ground cover where it stays mild all year or you know you
will have snow on the ground from December to March. On winter
exposed sites ( below 0 degrees F) it will give you problems in inland
summer heat and it will give you problems in full afternoon
sun. In its range the summers do not get much above 80 degrees F.,
ever, and the soil is fairly dry from July to December. Ceanothus
prostratus will take some summer water and can tolerate garden
conditions fairly well, as long as it's kept cool in the afternoon.
If you have a mountain cabin or a house in San Francisco you'd like
to look like a mountain cabin, this is one of the plants you should
be looking for.
We have a couple planted next to one of the greenhouses where it
gets almost full sun, just a little late afternoon protection, and it
is growing fine. It's mounding about one foot tall.
