Pictured are a yucca moth pollinating a yucca flower (L), and a milkweed beetle and milkweed flower.

We went down to the U.S. Botanic Garden on the National Mall on Friday to see their annual "Seasons Greenings" holiday exhibit. We used to go every year, but it wasn’t staged during the pandemic, and we missed it last year. They’ve moved their wildly popular model train display outdoors, accompanied by a delightful collection of pollinators, but still had the DC landmarks made entirely out of plants inside the conservatory. I didn’t photograph all the landmarks again, just the new ones; the others appear at the very beginning and towards the end of this gallery http://pbase.com/helenpb/america_return_washington_2_botanic

According to the Botanic Garden website:

“Our popular annual holiday display ‘Season’s Greenings’ features model trains in the gated outdoor gardens, festive lights throughout the Garden, and the poinsettias, holiday decor, and D.C. landmarks made from plants inside the Conservatory. On the lawn in the gated outdoor gardens, G-gauge model trains circulate from 10:00-5:00 daily through displays of pollinators made from plant parts. These scenes range from oversized models of native U.S. flowers like milkweed and bats pollinating a banana to an orchid bee pollinating a vanilla orchid flower, a chocolate midge pollinating a cacao flower, a lemur pollinating a traveler’s tree flower, and more!”
