americana var. heterophylla looking up trunk into the crown

I chose to profile the white basswood tree because it’s a North American Linden of impressive size in our collection. Its common name, basswood, is derived from the tough fibrous inner bark called “bast” that is used to make ropes, baskets, mats and many other lightweight wood products.

Of the 250 magnolia specimens, there are 38 species, subspecies and varieties (i.e.

December 2019 Plant Profile: Sequoia sempervirens

Sequoia sempervirens, cultivar Adpressa

Having grown up in northern California, I came to the Seattle area with a treasured tree in my heart and could quickly answer the “favorite tree” question commonly asked in horticultural gatherings. Though my neighborhood was a bit inland and to the south of the coast redwood range (and so was surrounded by majestic oaks most of my days) it was the stunning Sequoia sempervirens forests along the northern coast where I hiked and camped which I considered iconically and perhaps spiritually my home.
