7 Best Perennial Flowers To Grow In Montana

When planning to grow perennial flowers, you should consider a variety of factors, such as soil, climate, and time of year. Because of the unpredictable Montana weather, it can be difficult to determine when to plant flowers.

It’s best to start seeds indoors as early as possible, so they can begin to root before they’re exposed to the outdoors. Also, it’s important to learn when the last frost is expected in the area.

A surprise frost can kill plants much more quickly, so watch the weather closely and plan ahead to prepare for any potential emergencies.

Centaurea Montana, also known as Mountain Cornflower, is a stunning flower. It blooms in late spring and early summer, and the flowers are reddish blue in color.

It grows in upright clumps. It’s a great choice for the garden because of its colorful flowers. The petals droop, making it a delight to look at and admire. If you’re looking for a plant that will last through several seasons, this is the perfect plant.

Delphiniums are a favorite among perennial flowers. This plant produces flowers in a range of colors, from white to deep blue, and a wide variety of hues.

These flowers are best when planted in a sunny location and are ideal for borders, patios, or the landscape. Their delicate petals will fall off easily after a few days, making them an excellent cut flower. If you’re interested in growing perennials, be sure to consider this flower variety.

Echinacea is a shade-loving perennial with delicate pink blooms. This plant is popular with butterflies and bees. It has a spiny center, which makes it unpalatable to deer.

It’s hardy and drought-tolerant in USDA zones 3-8. There are many species of this flower in Montana, and many are drought-tolerant as well. It is a must-have in any garden.

Daylilies are a favorite perennial in the state. They are prized for their bright colors and waxy blooms. Iris plants need full sunlight to thrive, and they are hardy in USDA plant hardiness zones three through nine.

However, be sure to read labels carefully. Not all iris cultivars are hardy in all climates, and some are not even hardy in certain areas.

In the summer, the mountain cornflower can self-seed in your garden. You can divide it every two years and transplant the pieces elsewhere to ensure the plants’ survival.

This perennial flower is a favorite in the summer. You can even grow a beautiful garden in the winter in the mountains.

The weather in Montana can be unpredictable. Some days it snows in July, while others are sunny. The snow can be heavy in the winter, but that doesn’t mean it can’t kill the plants.

Society Garlic Plant

There is nothing more striking and distinctive than the lush green foliage of Society Garlic with its soft, lilac-colored flowers.

The beauty of this groundcover makes it one of the most versatile groundcovers available, especially since it spreads slowly and propagates easily.

This means that it will be flexible and adaptable to whatever the situation may be, wherever you may need it.

Also, it can be used as a house plant in colder regions because of its showy appearance.

The Society Garlic can add visual interest to your garden all year round, regardless of the weather outside since it is tolerant of both cold and drought.

However, if you live in a chiller part of the county, simply bring your Society inside so that it doesn’t get ruined by the cold.

There is something striking about its larger, tubular flowers and the cream-striped leaves no matter where they grow.

Early summer is the time when the elegant Delphinium Blue Lace (Delphiium elatum ‘Blue Lace’) blooms with brilliant spires of true sky-blue flowers.

As the flowers get close to their end, you should trim them down to encourage reblooming. In the late summer and fall, if you remove those first blooms, you will be rewarded with another excellent display.


Purple Dome New England Aster


Purple Dome New England Asters, Aster novae-angliae ‘Purple Dome’, have bright purple daisy-like flowers with yellow centers and bloom profusely throughout the growing season. Asters are some of the most spectacular flowers in nature.

Early in the fall, the purple blossoms of the Asters Purple Dome completely cover the plant and provide a lovely display. It is a favorite of butterflies and birds alike.

In soils of moderate fertility and with adequate drainage, ‘Purple Dome’ will grow well in full sun, but it can also withstand some afternoon shade.

Deamii prefers full sun to partial shade, and the soil should be rich and well-drained. You can divide the colonies during the autumn or spring.

A black-eyed Susan is an excellent choice for the middle of a border in late summer. Deamii should be displayed in bold drifts in a sunny or partially shady location that doesn’t dry out over the summer.

This plant will quickly become one of your favorites with its teethed, mid-green leaves and excellent long lasting cut-flowers!
