Arboretum Bulletin Fall 2021 Volume 83, Issue 3 | Page 20

Fall color ranges from burnt sienna to brick red . There ’ s a particular dawn redwood I look for each fall on my walk to work . Its fiery color looms over a blue , two-storey house . The homeowner told me this tree was a seedling given away in a fast-food “ happy meal ” when her children were small , and it has been growing happily ever since . In the Arboretum , a great place to view dawn redwoods is Rhododendron Glen , where there are four mature specimens . Taxodium distichum ( bald cypress ): This medium-sized tree in the cypress family is native to the Atlantic Coastal Plain , and to swamps and bayous of the U . S . Southeast . According to an article on the American Conifer
Bald cypress
Society blog , the autumn color is orange , and leaf drop depends on geographical latitude . In northern climes , bald cypress is wholly deciduous , while it is “ tardily deciduous ” in the South . The fall foliage display of the bald cypresses along Arboretum Creek in the Pinetum shouldn ’ t be missed !
Maidenhair tree
Ginkgo biloba ( maidenhair tree ): This conifer relative from China is widely cultivated around the world for its distinctive form and foliage , which turns bright yellow in fall before quickly dropping . It is the star of Japan ’ s annual Icho Matsuri foliage festival , held at Meiji Jingu Gaien — a ginkgo-lined avenue — in Tokyo between mid-November and early December . The synchronous leaf drop of ginkgo trees growing together is the subject of Howard Nemerov ’ s poem , “ The Consent ”
( www . poetryfoundation . org / poems / 53817 / the-consent ): “… the golden and green Leaves litter the lawn today , that yesterday Had spread aloft their fluttering fans of light .” A beautiful ginkgo stands sentinel by the gate to the Graham Visitors Center parking lot at the Arboretum . m
