Today we published our first blog article, which provides a much needed update about our progress. Link in bio. You can find the PBG Journal (blog) under “Learn” on the website—this may change.

We’ve been very quiet for a while, but we want to let you know that we are still alive and kicking! We are just making big moves that we can’t really talk about, yet.

Over the next few weeks, we hope to lift the veil on what what’s been happening behind the scenes this past year. There will be a lot of big, exciting changes in the very near future and you can follow them on our social media, blog, and newsletter.

Thank you, everyone!

Plant of the Week - Osmanthus fragrans Osmanthus

Plant of the Week - Osmanthus fragrans

Osmanthus fragrans, also known as fragrant osmanthus or fragrant olive, is an evergreen shrub native to the Himalayas, China, and Japan. During the fall season, it produces small, fragrant flowers that fill the air with a delightful aroma, making it a popular choice in landscaping.

In various parts of Asia, these flowers are used in teas, jams, sweet cakes, dumplings, and soups. In the mid-1800s, horticulturists created interspecific hybrids by crossing O. fragrans with O. heterophyllus, resulting in O. x fortunei, another remarkable fall-flowering plant for landscaping.

The genus name Osmanthus derives from the Greek words ‘osme,’ which means fragrant, and ‘anthos,’ which means flower, perfectly reflecting its aromatic blooms. The specific epithet ‘fragrans’ also aptly describes its fragrant nature.

Plant of the Week - Colchicum autumnale Colchicum

Plant of the Week - Colchicum autumnale

Colchicum autumnale, also known as the autumn crocus, is a perennial plant native to southern Europe and is renowned for its beautiful fall blooms. Despite its common name, C. autumnale is not a crocus at all, as it belongs to the family Colchicaceae, while crocuses are more closely related to irises (Iridaceae).

Growing from an underground corm, C. autumnale produces leaves in the spring before going dormant again in mid-summer. It re-emerges in September and October to showcase gorgeous lavender-pink flowers. Colchicum is highly toxic as it produces the chemical Colchicine. Medically, Colchicine is used to treat conditions like gout and is also employed to double chromosomes in living cells. When controlled, this can be a valuable tool in plant breeding, but can be extremely harmful to animals when ingested.

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.
