Case in point is the Geranium. Most often when folks hear the name Geranium they think of Grandma's old raggedy plants with bright colored flowers on a leggy plant. Actually those plants are Pelargoniums also called Martha Washington pelargoniums.
The real, honest to god Geraniums are low growing border perennials with lovely pastel flowers, finely divided leaves and delicate texture.
Divide every 3-5 years as the plants get thin, don't bloom as much and get dead sections.
Pretty hybrid of Geranium incanum. Check local nurseries for hybrids in spring.
There are some good mail order sources for Geraniums as well as specialty nurseries.
Check the web for options.
Hardy geraniums have the common name- Cranesbill. The seed pods have the look of a birds beak.
The native species of geranium can be weedy.
Hybrids, large flowered forms are hardy to heat and cold. They can tolerate sun and light shade.
Good drainage is a plus but not a must.
