Some of the most unique wildflowers are purple. They attract wildlife such as bees and caterpillars.
Many types of common purple wildflowers are also used to decorate parks and gardens.
A wide range of wildflowers in North America don’t come in a main purple color but maybe purple if they’re violet, lavender, or pink. Other species are only purple.
Some of the typical common purple wildflowers of North America include the following species.
Table of Contents
1. Common Milkweed
A typical perennial, Common Milkweed (Asclepias syriaca) is a wildflower often seen in a purple color.
The color of Common Milkweeds is highly variable. Purple and pink nuances are highly common followed by rarer white and cream-colored flowers.
This type of wildflower grows to a maximum height of just over 5 feet.
While its colorful purple blooms are attractive in gardens, rapid rhizome-based spread makes this plant less than ideal for home cultivation.
The Common Milkweed is a food for hundreds of insects and bugs, including the Monarch Butterfly’s Caterpillar.
2. Common Blue Violet
The Common Blue Violet (Viola sororia) is most likely found around woodlands. This species grows and thrives on the ground where it may even live in partial shade.
The species is short, but it grows to 10 inches in width. It features colorful purple flowers and dark green leaves that are shaped like a heart.
An ideal species in gardens, Common Blue Violet can grow in moist soils.
This species should be planted in containers or backyards as it tends to be a high-risk weed when it spreads on lawns where it can be difficult to remove from.
