Herbaceous Plants – May 2020

Herbaceous Plants is one of many monthly courses offered as part of the Horticulture Certificate Program. A monthly course is $115 for Conservatory members and $135 for the general public, and includes five classes (a value of $23/37 per class). Classes may not be prorated. Students must complete nine of the courses to earn the certificate. However, there is no obligation to complete the program; students are welcome to sign up for as many or as few of the courses as they would like.

This course will dive deeply into the fantastically varied world of herbaceous (non-woody) plants. From the ground upward we will learn about geophytes (bulbs, corms, tubers and rhizomes), pteridophytes (mosses and ferns), annual/biennial plants, ‘weeds’, perennial plants that can hug the ground or grow far into the air, cacti and succulents, tropical herbaceous plants that are often used as annuals outside and houseplants inside Ohio homes, orchids, vines and epiphytes (air plants) typically growing in the canopy of trees. The primary learning outcome is to understand the basic characteristics of herbaceous plants and be able to identify common examples of the many types of herbaceous plants found around the world.
