Mahonias have long been garden staples, but few people have ever seen or tried the rare Mahonia russellii. Discovered in 1984 in Vera Cruz, Mexico by the UK’s James Russell, this member of the “paniculate” clan of mahonias is more closely related to other Southern Mexico and Central American species, than anything most of us grow in our gardens. In other words, there is no way we should be able to grow this outdoors.
Below is our specimen flowering in the garden just prior to our low of 11 degrees F and three consecutive nights in the teens. Surprisingly, it escaped with what appears to be minor foliar damage, and of course a loss of the floral show.
