Beyond the Hype - Recent and Not So Recent Trees and Shrubs of Distinction

John E. Elsley

Recent years have witnessed an explosion in
new tree and shrub offerings with the associated
promotional hype far exceeding the potential
performance in many instances. John Elsley
will discuss his personal selection of recently
introduced trees and shrubs, with a bonus
selection of some older introductions that have
been overlooked in the “new and improved”
stampede.

Lyme Disease in Pennsylvania

Steve Jacobs

Lyme disease rarely makes the news anymore,
but it should. Instances of this illness continue
to rise, as the tick responsible for transmitting it
continues to increase its range. Effective ways to
manage the disease have been identified in the
past, yet little funding is earmarked for ongoing
research. In spite of this dire overview, there
are ways to manage Lyme disease. Steve Jacobs
will talk about the history, diagnosis, treatment,
epidemiology, vector ecology, management
tactics, and a brief review of some of the latest
research findings of Lyme disease.

Creating Landscapes with Roses

Stephen Scanniello

This presentation is designed to change how
you think about using roses in the landscape.
Traditionally roses have been considered as
the fussiest of garden plants, favorite targets
of insects and diseases, in constant need of
pruning, and kept apart from the rest of the garden. More recently, however, there has been a strong movement away from this school of thought
and entire classes of roses are becoming available
that are easier to grow, require less spraying, and
are more diverse, encouraging a more creative
approach to how we use them in the garden.

Lunch

From Mountains and Meadows to the Garden Center Staff

Linda Guy

Linda Guy will guide us through the steps from
preparing for a wild collecting plant expedition
to offering promising new plants for sale to home
gardeners. Stops along the way include meeting
the requirements of USDA, processing the plants
from the field, growing them in quantities
available for wholesale, the trialing process, and
finally, the marketing campaigns.

climates.
