We went for a short walk today; the sun was partly out, and the mountains looked lovely. We noticed a faint but definitely pleasant odor; something sweet. It was a shrub about five feet or so tall, in full bloom. The blossoms were yellow strands, with slightly darker maroon cup like strands of the calyx in their center. I couldn't think what it might be; it reminded me a little of certain Australian mimosas I'd seen in Southern California. It was a bright, cheery yellow on a somewhat grey day, and I noticed I could see a few others in nearby yards. There's a larger picture
here, but this one shows the typical "vase like" form of the shrub; tall, with branches on either side, in fairly even order.
It turns out that the shrub was a witch hazel, or more specifically,
Hamamelis x intermedia "Arnold Promise." This particular variety, which thrives in the Pacific Northwest, blooming from January to March, and subsequently bearing golden yellow leaves, was an inadvertent cross discovered at the Arnold Arboretum. In 1928 botanist William Judd collected seeds from one of the arboretum's
Hamamelis mollis varieties of witch hazel, and planted them. In quick order, it became clear that the young plants were hybrids of
Hamamelis mollis pollinated by a
Hamamelis japonica which grew nearby in the arboretum. One of the offspring in particular stood out, with fragrant vivid yellow blossoms. 1944, Alfred Redder named the new hybrid
Hamamelis x intermedia, and in a few years, the arboretum began releasing plants to retail nurseries. For the curious, the gory details are
here in a 1981 .pdf from the Arnold Aboretum's journal.
Witch hazel isn't related to witches specifically, alas; it's a fairly common European shrub (and there are, of cours Asian varieties, especially in Japan); it is not cognate with wicce/wicce which gives us "witch." Rather, the witch of witch hazel is related to the Old English verb
wican meaning "to bend," cognate with wicker. Infusions of Witch hazel bark and leaves, typically in an isopropyl alcohol solution, are often used to treat cuts, bruises, and minor abrasions since it has some ability to constrict blood vessels.
