There are many native wildflowers that will survive cold winter conditions and thrive in the garden.

There are many native wildflowers that will survive cold winter conditions and thrive in the garden.

These North American native wildflowers will do extremely well in extended cold winter conditions. They bloom nicely in the warmer months and survive harsh winters. Many will feed songbirds if you leave the stalks and seedheads standing past fall cleanup. As a bonus, they will also often drop seed and create lots of little “volunteer” plants nearby. Taking advantage of the hardiness of these native plants, you can quickly fill a lot of garden space with strong and hardy flowers.

1. Blue Flax (Linum Lewisii)

This hardy perennial is also known as Prairie Flax. This is one of the easiest wildflowers to grow because it needs almost no extra care. It doesn’t even need to be watered. In fact, the only way to fail with Blue Flax is to over-water it. Just put it in a dry spot, and let it thrive on its own It prefers part-shade, but will also grow in full sun. Blue Flax must have dry soil.

Blue Flax offers a mass of light blue flowers early in the season.

Use Native Wildflowers as Accent Plants

Bear in mind that native wildflowers don’t have the exact same look as the plants you may buy at the garden store. They are a bit larger, more wild-looking, and sometimes have irregular flowers. That is the nature of wildflowers. If you prefer a more structured garden, use these lovely wildflowers toward the back , or as accent plants within a carefully planned flowerbed.

8. Cowslip (Caltha Palustris)

Cowslip is also known as Marsh-Marigold or Yellow Marsh Marigold. Marsh Marigolds grow well in partial shade. They need very wet soil, so streambanks and ponds are good options to start these plants. They will spread well on their own, once established.

Perennial Wildflowers

Most of the plants on this list are perennial wildflowers. That means that the top of the plant will die back in the winter, but the roots will continue under the soil. The leaves and stems will grow back when the temperature warms. Some of these perennials will also re-seed if allowed to stand over the winter months.

You might want to create a wild spot in your garden, grouping different colors of plants without regard for height or color. Just plant them in the correct soil and sun conditions, and let them grow together. This strategy works well in raised beds because the structures create a sense of containment. Raised beds also make weeding easier when you are using a mixed planting.

Wildflower Color Groupings

A great way to enjoy these plants is to group them by color and surround them with a sharp, clean border of stone or fencing. The sharp edge contains the plants and makes a nice contrast.
