Plant Profile: Snapdragon (Antirrhinum majus)

by Karen on October 18, 2010

A well grown snapdragon is a beautiful plant; a bouquet of snapdragons in a vase is sure to evoke feelings of old fashioned charm and nostalgia. But I must confess, as much as I love these fabulous flowers I do not have much luck growing them although I have some neighbors that produce breath-taking specimens each fall. Snapdragons are cool weather plants and grow well in northern areas where summers are cool but will not grow in the heat of Southern summers. They are best grown in fall and spring in such hot areas where they will be a welcome sight along with other cool weather plants like pansies and ornamental cabbages and kale. The trailing varieties are a bit more heat tolerant than the upright forms and look good in containers or the front of the border. Dwarf, medium, and tall varieties are available too.

The botanical name comes from two Greek words, anti meaning opposite, and rhis meaning snout, and probably refers to the resemblance of the flower to a dragon’s head. If you want to entertain your kids or grandkids take a flower from the stalk and hold it so that the “lip” is at the bottom; then gently squeeze the sides between your fingers and watch the dragon snap.
