Keep the Color Going Right Through September
Most flower gardens are at their best during the first half of the growing season. By late summer, many annuals and perennials are starting to fade. To keep the color going strong, your garden needs to include plants that are at their best during the second half of the growing season.
Some of the best flowers for late season color are summer-blooming bulbs. These heat-loving plants typically maintain a low profile during the first part of the season, but by midsummer, they are flourishing and blooming their heads off. Since there’s no need for these plants to set seeds or begin preparing for winter dormancy, they can continue growing and flowering with abandon, rushing headlong right through the fall.
Having a garden that stays colorful month after month is all about picking the right plants. Here's a selection of summer-blooming bulbs that you can count on to bloom right through late summer and fall.
Dahlias are dependable, high-energy plants that put on a spectacular show from July through October. The flowers come in all colors and the plants come in sizes that are suitable for containers, landscaping, flowerbeds and cutting gardens. When you plant dahlias, you never need to worry about running out of flowers.
Caladiums are tropical foliage plants with brightly colored leaves. They love heat and humidity, so they stay fresh and attractive in weather that makes other plants wilt. Caladiums grow in sun or shade, and can be planted as a ground cover, as edging for a pathway, around shrubs and trees, and in containers.
With leaves that can measure up to 3 feet across, elephant ears are always a “wow”. The warmer the soil and the hotter the weather, the bigger and more impressive they get.

Canna lilies are bold plants with a big presence. They can grow up to 5 feet tall and have big, glossy leaves as long as your arm.
