Yucca Linearifolia 'Dusky Blue'

Young Yucca linearifolia 'Dusky Blue' surrounded by colchicums in my front border

     I have previously mentioned, here and here, that I grow Yucca linearifolia in several places in my garden.  This is a very choice yucca, apparently related to Yucca rostrata, except that the leaves are narrower and more succulent.  This yucca was first discovered in the 1980's by the Peckerwood and Yucca Do guys on one of their many forays into Mexico, and according to the Yucca Do catalog, it is prospering at Peckerwood Garden and has reached a height of 5 ft. there.  For those who don't know, Peckerwood is a famous Texas garden, now under the Garden Conservancy umbrella, I believe.  I have never been there, but have seen many pictures of it, and it is one of the gardens at the top of my list to see.
     Anyway, Sean Hogan, being the Yucca King, had some good looking, albeit small plants of this yucca for sale a few years ago when I stopped at Cistus as I was passing through Portland one day, and so, of course, I bought 5 of them.  These were labeled Yucca linearifolia 'Dusky Blue', which must mean that they are a selection which has bluer foliage than the usual, although that is just a guess.
      I gave one to my sister who lives in Salem, and planted the rest in my garden. One went into the front border and the rest I planted near the lionness sculpture.  That was about 3 years ago, and so the plant you see in the picture is the growth after that time, and you can see that it is advancing at a good rate.  I would guess that they should start showing some trunk in a year or two.  I should add that the one in my sister's garden is significantly bigger than mine, which just illustrates the greater heat available to plants in the Willamette Valley as compared to here.  Most plants in her garden seem to grow at a slightly faster rate than in mine (and she is not secretly fertilizing them).  Indeed, just about the only plants that might do better here are the more cool loving New Zealanders, such as Aciphyllas and Myosotidiums, and  of course, Meconopsis.
