(Bartram Oak, Burrier Oak)
Variable in the shape of its lobed, oblong leaves, European turkey oak forms entertaining acorns that have a frilly, scaled cap. A rounded but spreading canopied deciduous tree was first described by the American botanist John Bartram as one was growing on his farm. It is occasionally but rarely formed by a natural cross between the willow oak (Quercus phellos)and northern red oak (Quercus rubra) in the eastern United States. Its bark is smooth and ghostly gray.

The leaves are extremely small and medium to dark-green and densely covered in silvery hairs. The foliage texture makes one think this plant is a moss, or a...

Ravenea is a small genus of palms, all native to Madagascar and the Comoro islands. There are approximately 17-species each with a very different look and habitat preference.
The solitary trunks of Ravenea range from short to tall and thin to stout, and are usually lightly colored, tan or gray, and sometimes swollen at the base. They are topped with dense whorls of feather-like or pinnate leaves, often twisting at the tip and gracefully arching.
The genus Rhaphiolepis comprises approximately 15 species of shrubs and small trees from subtropical and temperate regions of East Asia.
These cold-tender evergreens bear leathery, glossy-green, oval to lance-shaped leaves with toothed or smooth edges. Newly emerged leaves are often red or bronze. Loose clusters of small, five-petaled, unscented or mildly fragrant flowers appear toward the branch tips in late winter, spring, or summer. The star-shaped blooms are pink, white, or red,...
