What White Perennials Bloom All Summer?
Flowers are wonderful to have during the summer.
They can make your space feel fresh and beautiful and always smell amazing.
If you’re going to put in the time and effort to grow perennials, you’ll want to make sure they can last the entire season in bloom.
If you choose a perennial that blooms all summer; you can enjoy them longer.
These flowers can easily spruce up your garden, walkways, and borders.
White tends to stand out and make other colors “pop,” too, so you can use them with other blooming flowers for outstanding results.
Here are eight of the best white perennials that bloom all summer long.
1. Iceberg Rose
Iceberg roses are very easy to grow.
They require full sun for at least six hours per day and prefer well-drained soil. Iceberg roses are stunning while blooming, so you’ll enjoy having them around for the entire summer.
Since they require direct sunlight, they’ll do great outside in your flower bed. Ensure the soil has a pH level between 6.5 and 7.
Then, plant the roses in holes at least 18 inches wide. The hole you create also needs to be deep enough for you to cover the roots easily.
Once the iceberg roses become established, you should spread compost or manure over the top of the soil.
When these roses have access to the proper nutrition, they produce large, full white blooms. The more nutrition they have, the more beautiful they’ll be!
The rose bush will bloom all summer, with blossoms covering the entire shrub. If you have space to put in a trellis, you can even use climbing iceberg roses with great results.
2. Annabelle Hydrangea
Annabelle hydrangeas require different care than the above iceberg roses.
These flowers do well in partial and full sun while getting at least five hours of direct sunlight. If you live in a cold place, you can stay in the sun all day. Although, they prefer shade in hotter areas.
The blooms on the Annabelle hydrangea are so large and full that they collect water during rain. When that happens, the flowers can fall over.
You can also prune the Annabelle bush each year. Doing so helps the plant form stronger branches with time. The flowers also become smaller, but they still look beautiful.
These flowers are very strong bloomers, so that they can handle a lot of pruning.
You’ll want to prune about 18 inches off them for the best results.
If you don’t like how this looks, prune the bush down to the ground, and next year you’ll have a fresh start with full blooms.
Next, you can also try adding a fence near the plant. It blocks some of the rain and can offer support to the larger blooms that tend to fall over.
In short, the Annabelle hydrangea is stunning throughout the summer months.
3. Japanese Anemone
The Japanese anemone is a white flower that blooms during the late summer and into the fall.
The blooms add a fresh, bright appearance to any garden.
