Plant by plant, I am putting names to the flowering shrubs in our Rwanda garden. Here are two more, supplied by the readers of Fine Gardening’s Garden Photos of the Day, from my pictures on Monday and Wednesday.
Eranthemum nervosum (aka E.pulchellum) or blue sage or blue eranthemum has gentian blue flowers, as you can see. In the family Acanthaceae, it is native to India. It will grow 4′-6′ and likes light shade. It will grow in the garden in (U.S.) zones 10b and 11. (I think all the shrubs in this post would be suitable for pots in colder climates.)
Brunfelsia latifolia (aka B. australis) or yesterday, today, and tomorrow plant is native to South America. It is very fragrant at night. Our largest specimen, which needs pruning, is about 5′ tall, 4′ wide. It is in the same family as potatoes, tomatoes, eggplants, and petunias — Solanaceae or nightshade.
Y.T.T. likes well drained, moist soil and full sun to part shade — its habitats are light woodlands and thickets — and grows in the garden in (U.S.) zones 9-11. The flowers open purple, then go to lavender, and then white. The genus was named for early German herbalist Otto Brunfels (1464-1534).
I’m just showing this off. I already knew its name.
Brugmansia is native to tropical South America and, like the Brunfelsia, is also in the family Solanaceae. It is also called angel’s trumpet or datura (the name of a closely related genus). The semi-woody shrub can branch off like a small tree and grow to 6′-20′. It has a fragrance in the evening. It likes moist, well-drained, fertile soil, full sun to part shade, and grows in the garden in (U.S.) zones 9-11.
