Orchid and Fungi Relationship: A Discussion of Mycorrhizae | Tim Choltco
Tues., Oct. 17 | 7 – 8 p.m.
Live webinar presented through Zoom
$12.50 members | $15 nonmembers
Objective: to learn about the interactions of orchids and fungi and how they both benefit from being in relationship
Level: Beginner to Intermediate
Prerequisite: None
Some plant families are completely dependent upon mycorrhizal interactions for seed germination, like the Orchidaceae (orchids). Mycorrhizae are a symbiotic relationship that occurs between fungi and plants. Approximately 90% of all vascular plant families have a form of a relationship with mycorrhizal fungi. These relationships occur when certain types of hyphal fungi colonize the roots of plants. Such relationships offer benefits to both the plant and the fungi. The plant obtains nutrients and increased water and mineral absorption via the addition the fungal hyphal network. The fungi in return obtains carbohydrates that it cannot synthesize itself. This presentation is an introduction to these interactions, with a focus on orchid and fungi relationships. This presentation is from the botany side rather than the mycology side of the coupling.

Objective: Students will be able to name a wide variety of landscape plants and discuss their cultural requirements and landscape uses
Level: Beginner to Intermediate
Prerequisite: None
Sustainable plants are those which are non-invasive, have minimal pest and disease issues and are well-suited to the climate and soils of gardens in southwestern Pennsylvania. Sustainable plants are also those which provide ecological services such as host plants for butterflies, nectar and pollen producers for bees and other pollinators and seeds and berries for birds. Native plants fit this definition along with many other wonderful landscape plants. In this class, students will become familiar with many landscape plants (perennials, trees and shrubs, etc.) learning their cultural requirements, how they grow and be able to identify them. This class is both lecture based and field study, as students have the opportunity to see these plants in the landscape. Ecological Gardening and Landscape and Garden Design core course.
