The exciting part of gardening is designing the perfect garden in your view, from early spring planting to flowers for fall color. Everything from colour, plant type depending on the sun exposure, layout, hardscape, and the most exciting one is planting time, must include in your gardening plan.
Of course, you can plant as you go or plan it. I mostly do both. Depending on your gardening zones, spend time in the spring or early fall to view the garden for what you can plant for late summer-blooming flowers.

There are many plants, shrubs, trees, or flowers for their specific interest based on the season. For example, you can have a garden with continual blooms from early spring to fall.
You can get some inspirations from your morning walks, garden magazines, gardening books, public garden, or even garden catalog for seasonal garden interests. The goal is to have something bloom from early spring to fall if you are into flowering plants.
Plant a foundation planting with these low growing flowering shrubs. Then you can create a colorful garden bed with these easy to grow annual flowers. Some annual flowers like snapdragon or calendula will tolerate light frost, which is a typical forecast in the early fall.
To keep the cost minimum on gardening, you can only plant shrub and perennial flowers that keep coming back year after year. Some of these easy to grow perennial flowers blooms from late spring to fall with minimal care.
When To Plant Perennial Flowers
The best time to plant perennial flowers is in the early spring and late summer or early fall when the ground is workable and the day is warm. Typically between March to May, or September to October, depending on your gardening zones.
My garden is in zone 4, so I would plant bare-rooted plants in the middle of April through May. Perennial seedlings from indoor seeding or garden center planted in May after the last frost pass or late summer before the first frost comes, which is around September 12th.
This planting period will give more time to establish the root system before the winter comes. Most perennials will bloom in the second year and double their size year after year, which gives you more plants for free by dividing, root cuttings, or transplanting volunteer seedlings.
Late-Summer Blooming Perennial Flower For Part Shade
Part shade areas typically only get a few hours of sunshine during the day. That could be only morning sun or afternoon sun.
This bright yellow plumed flower is one of the native wildflower cultivars. It is hardy to zones 2 to 8. Depending on the variety, goldenrod will bloom from mid-summer through fall. The common goldenrod or Solidago Canadensis will bloom in the late summer.
Goldenrod will grow in the well-drained soil and be somewhat drought tolerant once it is established. However, some regions might put goldenrod on the invasive plant list. So, it is better to gather information first based on your area before you plant it in your garden.
I plant the Solidago Canadensis in the front yard that gets afternoon sun only beside the lilac bush. The plant did not spread and stay on the same spot for over five years.
