Herbaceous Perennials Online Course

While trees, shrubs, sub-shrubs and ground-covers are abundantly focused upon, we often don't pay enough attention to those plants that are more transient in nature.

Herbaceous Perennials Overview

In northern latitudes, herbaceous perennials die and disappear in winter, and then arise completely renewed come spring.

Herbaceous Perennials Are Often A Garden's Foundation

Unlike annuals that must be replanted every spring, herbaceous perennials are easy to care for and require less of a time commitment. 

And because of their dependability and wide array of colors and textures, herbaceous perennials are capable of filling a multitude of roles in the modern American diminutive garden. 

What Makes This Course Unique

By the end of this 10-week online course, you will know how to catalog details on plants of interest and you will be able to grow and maintain your own perennials.

The course is broken down into the following sections:

  • Garden design history
  • Residential design
  • Soil/water/nutrition
  • Pollinator gardens
  • Maintenance of herbaceous perennials
  • Ethnobotany

Your weekly activities will include instructor-led lectures, lively discussions and a plant of the week exercise.

And with direct access to expert instructor Al Shay, it's like you'll have a personalized gardening consultant with you every step of the way.
