Plant of the Week - Gentiana asclepiadea Gentiana

Plant of the Week - Gentiana asclepiadea

Gentiana asclepiadea, commonly known as the willow gentian, is a species of gentian native to Europe and parts of western Asia. Primarily found in mountain woodlands, it produces strikingly blue to purple flowers in late summer and early fall.

A hardy species, G. asclepiadea thrives in moist, partly shady areas of the garden and is resistant to deer browsing, making it wonderful for late season color.

Plant of the Week - Welwitschia mirabilis Welwit

Plant of the Week - Welwitschia mirabilis

Welwitschia mirabilis, often just referred to as Welwitschia, is a living, yet ancient, species native to the Namib Desert of southwestern Africa. Growing from a deep taproot that can extend as deep as 30 meters (100 feet), Welwitschia produce only two leaves that elongate throughout its life. A slow grower, this living fossil has been found to live in the wild for nearly 2,000 years!

A diecious species, there are separate male and female Welwitschia plants. The female plants produce no flowers, but rather cones with papery seeds that can blow in the wind. While other cone-bearing plants are often wind pollinated, Welwitschia are pollinated primarily by insects, likely beetles or wasps.

Plant of the Week - Tillandsia usneoides Tillands

Plant of the Week - Tillandsia usneoides

Tillandsia usneoides, commonly known as Spanish moss, is actually not a moss at all! It is a widespread species of flowering plant that grows in tropical and subtropical locations, from the southern United States down into South America. Members of the genus Tillandsia are commonly referred to as air plants in the horticultural trade. This species, like other Tillandsia plants, is epiphytic, meaning it grows on trees and obtains nutrients and moisture from its surrounding environment, rather than from soil.

Throughout history, Tillandsia usneoides has had numerous ethnobotanical uses. It was commercially harvested well into the 20th century and used extensively as stuffing material for items such as car seats, mattresses, and various other products. Additionally, it has been utilized for its medicinal benefits, as well as for making rope, cloth, scrubbers, and more.
