Summer is here, and it’s time to get your landscaping game on! Flowers are a great way to add color, texture, and interest to your landscape. We’ve compiled a list of 10 of the most gorgeous summer perennials that will bloom in Pennsylvania. Read more below and discover what flowers you should be planting this summer!
1. Perennial Hibiscus (H. Moscheutos)
Perennial Hibiscus, also called the rose-mallow and swamp hibiscus, was bred from wildflowers native to Eastern and Southern regions.
The huge, vibrant flowers of the swamp hibiscus can be seen blooming from late spring until frost, and the stems die back every winter. They grow as perennials in zones 5 to 10 and require full sun with regular to abundant watering.
Typically growing in shades of red, pink, or white, these stunning blossoms can reach up to a foot across on stems that reach as tall as 2 to 8 feet high, depending on the variety.
2. Purple Wave Petunia (Petunia F1 ‘Wave Purple’)
Purple Wave petunias are more like vines, perfect for growing on retaining walls, hanging pots, or as ground cover. They require full sun and regular watering and grow as an annual in all zones. An interesting fact about petunias is that gardeners used to think of them as uptight plants until they were named an All-American Selection winner in 1995.
3. Profusion Zinnias (Z. Hybrida)
If you want to have armloads of flowers for bouquets and still be able to enjoy the bright colors while walking in your garden, then grow zinnias. Zinnias thrive in hot weather, as they require full sun. They are not a very demanding plant — they can grow in all zones; all they need is regular watering.
The Profusion zinnias category blooms well into fall. If you want flowers that resemble fluffy pom-poms, go for the double Profusion varieties in white, gold, cherry, and fire (orangish-red). If you want daisy-like flowers, then Profusion White, Orange, and Cherry are the right choice for you; they have even won multiple garden awards.
4. Globe Amaranth (Gomphrena Globosa)
If you are looking for a garden plant that blooms all year, these pretty clover-like flowers should be your first stop. These papery flower heads last a long time in the garden and make beautiful arrangements after they have dried out during wintertime.
Depending on the variety, the flowers are red, pink, white, lilac, or purple. Two types that stand out are ‘Strawberry Fields’ and ‘All Around Purple.’
Globe Amarnath requires full sun to partial shade, moderate water and can grow as an annual in all zones.
5. Stella de Oro Daylily (Hemerocallis)
These tough, trouble-free daylilies produce showy flowers on a mound of sword-shaped leaves. Stella de Oro daylilies require regular water, full sun to light shade, and grow as a perennial in zones 3 to 9.
The Stella de Oro is a low-growing daylily that keeps churning out new stems with golden yellow blossoms for up to five months, which is far longer than most other types of lilies. Each stem holds a multitude of flowers that open in succession, with each bloom lasting only one day.
6. Evergreen Candytuft (Iberis Sempervirens)
The Evergreen Candytuft grows as a perennial in zones 5 to 9 and needs full sun to part shade and regular water.
These low-growing clumps remain attractive year-round. The small clusters of delicate white flowers appear in spring and remain all the way into the fall, while its shiny, dark-green leaves stay on all winter.
7. Brown-Eyed Susan (Rudbeckia)
When you want a bright, cheery little flower with an eye-catching center pattern that will bring joy to your garden or home, look no further than the Brown Eyed Susans. These flowers come in orange and yellow shades with raised brown polka dot centers. They grow as an annual or perennial depending on what variety you purchase and require full sun and moderate to regular water amounts.
The R. hirta varieties are grown as annuals and bloom from seed the first year; in warmer areas, they bloom during winter. Most other types are perennial and gradually form showy, spreading clumps that are as hardy as their wildflower ancestors, native to the East. The R. fulgida var. sullivantii ‘Goldsturm’ is an especially flower-covered variety.
8. Purple Coneflower (Echinacea Purpurea)
These 4-inchish pink to purple daisy-like flowers bloom from mid-summer to autumn. The plant is hardy and unfussy, and after some years, you can divide clumps to get new plants. Also, the Purple Coneflower draws a lot of butterflies and lasts well as cut flowers.
Furthermore, the ‘PowWow Wild Berry’ that has rosy pink blooms was chosen as an All-America Selections winner.
9. Sunflowers (Helianthus Annuus)
Sunflowers are large, easy-to-plant, and magnificently showy flowers. The classic single-stem kinds such as ‘Russian Giant’ and ‘Mammoth Russian’ grow around 10 to 15 feet tall and produce massive flowers with edible seeds.
However, there are newer, shorter varieties of sunflowers. The ‘Ring of Fire,” for example, is around 4 to 5 feet tall and has 5-inch flowers that can easily fit in a vase. The ‘Sunspot’ is just 2 feet tall. While the ‘Indian Blanket’ branches into numerous smaller flowers that are suitable for cutting.
As the name suggests, sunflowers require full sun. They also need regular water and can grow as annuals in all zones.
10. Marigolds (Tagetes)
Marigolds are vibrant yellow or orange flowers that can light up any garden. Their odor can keep pests away, and they are excellent as cut flowers too. They require full sun and regular water and can grow as annuals in all zones.
Named an All-America Selection winner, the ‘Moonsong Deep Orange’ is a hybrid with frilly, densely packed flowers. On the other hand, many other marigolds resemble daisies and have just a row or two of petals around their dark center.
