What is a stumpery garden?

The Stumpery Garden is a horticultural oddity, serving as a public place for learning and exploration and demonstrating how trees can be utilized in a beautiful way.

Whole logs are placed upside down to display their root structure, and logs, branches, and pieces of bark are arranged to form walls and archways. Plants such as ferns, lichen, mosses, soft grasses, and trailing plants are encouraged to grow on and around them.

What is the relationship between fungi and the root system of a vascular plant?

Mycorrhiza describes a symbiotic relationship that forms between fungi and the root system of a vascular plant, such as a tree. As in all symbioses, both fungus and host benefit from the relationship, though in different ways. The fungus colonizes its host’s root tissues, improving the host’s moisture and nutrient absorption capabilities. In exchange, the host plant provides the fungus carbohydrates produced through photosynthesis. Some highly prized varieties of edible mushrooms, such as golden chanterelles ( Cantharellus cibarius) and king boletes ( Boletus edulis ), are mycorrhizal fungi, each with particular preferences regarding its symbiotic partner. You’re most likely to find king boletes under spruce ( Picea ), pine ( Pinus ), birch ( Betula ), and oak trees ( Quercus ), but other species in the Boletaceae family — many of which are edible — can be a bit pickier. American slippery Jack ( Suillus americanus) and aspen boletes ( Leccinum insigne ), for example, will grow in symbiosis with only Eastern white pines ( Pinus strobus) and aspens ( Populus ), respectively. Golden chanterelles grow in northern Georgia, most often in pine forests or under other conifers.
