Geraniums come in a broad range of flowers and colors and they are ideal for container gardens or filling garden beds. The plants can grow from 12 to 20 inches tall and can survive drastic temperature shifts. They prefer full sun and moist, well-drained soils, so you don’t have to stress about overwatering or giving the plants too much light.

Geraniums are one of the most popular options among gardeners because of their stunning blooms. To encourage new growth and continuous flowering, remember to properly deadhead the plants throughout the season. Geraniums can also be grown indoors as houseplants.

Fast-growing and vibrant, sunflowers make an excellent addition to gardens and containers. While you may be familiar with the mustard yellow blooms, you can also find sunflowers in a variety of different colors to suit your backyard space. As the name would suggest, they enjoy full sun, though they can also grow into late summer with regular fertilizing and deadheading.

In well-drained soil, sunflowers can grow from four to 12 feet tall. They are also drought-tolerant and perennial varieties will come back year after year. So, as long as they have the proper light requirements, and well draining soil, you won’t have to do much to keep these cheerful plants happy.

Daylilies are adaptable and hardy mostly because they can thrive no matter the weather. The plants can grow one to four feet tall and you should avoid planting near trees or shrubs because they will compete for water and nutrients.

These low-maintenance perennials are perfect for the forgetful gardener and those who want gorgeous blooms without the work.

It’s no secret that morning glories are hardy, in fact, they’re often referred to as a weed! While the royal purple trumpet-shaped flowers and heart-shaped leaves are easy to love, the plants tend to be invasive and should not be grown in the garden. They make a great option for attaching to a trellis or pergola, though.

Morning glories grow best in full sun with well-drained soil and they will quickly climb and spread six to 10 feet. As the name would suggest, the blooms appear in the early morning throughout the summer and early fall. They can also survive temperature drops and will continue to flower after the first frost.
