With proper care and attention, your garden will always look its best throughout the year. Some flowers bloom for extended periods adding a pop of color to your landscape, while others will only bloom for a short period, so you should carefully plan your planting schedule.
Petunias are among the longest-blooming flowers in your garden, with a blooming season that extends from spring to November. There are different varieties of petunias that you can grow in your garden with single or double blooms, and they come in every color except blue.
You can grow your petunias in containers or along your garden’s border, where they have access to full sun. However, if the weather is too hot, the partial shade will be appreciated in the heat of midsummer.
If your soil is too poor, petunias won’t work for you as they need to grow in light, fertile soil. Adding compost when they’re first planted and complementing the soil with liquid fertilizer on a monthly basis is recommended.
The bleeding heart flower grows from a shade-loving woodland plant that blooms in the cool spring but disappears when the temperature increases in summer. However, the roots stay alive to regrow in fall or next spring.
The drooping blooms come in shades of white, pink, and red and are toxic to humans and pets, especially dogs. Each stem grows about 20 flowers, adding the needed pop of color to your cottage garden.
The bleeding heart plant prefers partial shade, so you can plant it near a deciduous tree, where the soil is rich, moist, and well-draining.

If your soil is slightly acidic or alkaline, it will be suitable for growing sweet woodruff. It can even grow in sandy and clay soil.

The sunflower is one of the most popular summer flowers and will stay in bloom till fall. Each flower stretches from 3 to 6 inches wide with yellow, red, or mahogany petals and a brown center.

Sunflowers need full exposure to sunlight and don’t tolerate the shade. They tolerate dry and poor soil but grow best in well-draining soil.

Tulips are spring bloomers, growing beautiful flowers that come in shades of red, pink, purple, yellow, orange, green, white, and even black. Most cultivars grow one flower per stem, although some varieties can grow multiple flowers.
The perennial bulbs are usually planted in fall, especially under taller trees that provide partial shade in the hot months of summer. However, during spring, they need full exposure to sunlight.
You can grow tulips in slightly acidic soil, and the bulbs need to be watered regularly. After that, they don’t need to be watered that much and can grow off rainwater if it rains once or twice a week in your area. Tulips can grow in indoor pots and are toxic to humans and pets.
Also known as pig squeak, heartleaf Bergenia get their funny name from the sounds the leaves make when they’re rubbed together. The pink, red, and white blooms appear in April and May, and the leaves turn bronze in fall and winter.

This plant is fast-growing in optimum conditions and will bloom throughout summer with little to no maintenance once established. Marigolds need access to the full sun because the shade can make the plant become too leggy.
