Hardy annual flowers (also known as Hardy perennials) are plants that bloom year after year in zones 3 through 9. Hardy perennial flowers are also called evergreen or deciduous perennials because they have leaves that drop off each fall and return in spring. Hardy annual flowers include some of our favorite garden favorites. Dig into learning about the best zone 3-9 plants.
Here are Some Best Plants to Grow in Zones 3-9:
Known for its excellent flavor, ‘Boyne’ raspberry is a late-season producer that produces several crops throughout the growing season. This variety has bright red fruit that ripens mid-July. Cold hardy and known to resist diseases such as Raspberry Mosaic Virus (RVMV), Raspberry Black Spot (RBSP), and Raspberry Rust (RR). Fruit are high quality, firm, and very flavorful. In addition, ‘Boyne’ berries are large, averaging 4 inches in diameter. Plants bear heavily and can reach heights up to five feet tall. Raspberries are self-fertile, although cross-pollination does occur. The planting distance is 25 feet apart.
A newer cultivar released in 2004 from Washington State University, ‘Cascade Delight’ is a hybrid cross of the popular ‘Red Delicious apple and a selection from the University of Minnesota called ‘Nova.’ This cultivar produces large, bright red fruits with good flavor ready to harvest in July, although it tends to crack slightly during storage. It is a vigorous grower with medium-sized yields and is moderately resistant to fire blight. Rootstock will produce fruit one year after planting on 2-year-old caning. Plantation distances are 20 feet wide by 40 feet long.
Dwarf French Marigolds
The dwarf French marigold (Tagetes patula) is an easy-to-grow and great-looking plant that comes in many colors. Several different varieties are available, including yellow, orange, pink, purple, and white. They are perfect for containers and small gardens as they only need a little space to fill out their blossoms. They flower all summer long and attract butterflies and hummingbirds. Dwarf French Marigolds do well in sun or partial shade but require full sun if planted in hot climates.
‘Killarney’ is one of Ontario’s most popular varieties of strawberries. Its name originates from the town of Killarney, Ireland, where it originated, and the original plant came from. In 1961, Canadian nurseryman John Denton discovered the variety while working at the University of Guelph. He named it after his hometown of Killarney, Ontario.
This hardy, early-season cultivar produces medium-sized, medium to dark red berries with a sweet, delicious taste. They are ready to pick in mid-July, the year following planting, around a week after the fruit ripens on ‘Boyne’ plants.
Upright, sturdy canes grow very well, producing moderate yields. ‘Killarney” plants, available from Amazon.
This dwarf variety is great for container gardening because it doesn’t require support and grows quickly. In fact, it reaches about two feet tall and wide in just 18 months. It also spreads out evenly, making harvesting fruit throughout the season easy.
The best part about these dwarf raspberries is that they are thornless. You don’t even have to worry about cutting yourself while picking berries. And unlike some varieties, Rubus ‘NR7’ in # 2 Container isn’t prone to diseases like anthracnose.
The Royalty raspberry crosses the ever-popular ‘Honeycrisp’ and the original ‘Lapins’ varieties. It offers everything you want in a raspberry – good size, excellent flavor, early ripening, and disease resistance. In fact, Royalty is considered to be a true disease-resistant variety because it doesn’t produce much pollen, making it less prone to spreading diseases.
This everbearing variety produces large gold-colored fruit. It has a sweet, almost tropical flavor and a hint of apricots. ‘Anne’ plants are self-pollinating, and they grow vigorously. They produce abundant foliage and flowers throughout the growing season and tolerate drought well. In fact, they’re very tolerant of heat and humidity.
The fruits ripen in mid-July through the first frost, and they are ready to harvest about 30 days later. You’ll find that the quality improves as the weather gets cooler. So if you live in a warm climate, you may get more fruit earlier than this variety would normally bear.
A hybrid of ‘Red Delicious apple and ‘Golden Delicious,’ Midsummer is a good choice for home gardeners who prefer firm, juicy apples. This variety is resistant to scab and powdery mildew, and its leaves turn bright green when fall arrives.
A vigorous grower tends to branch, so prune back shoots before they become too thick. Midsummer trees are heavy croppers and require plenty of fertilizer.
A pomegranate tree is a beautiful addition to any yard, providing years of enjoyment. Pomegranates are native to China and India, but today they thrive in many areas of North America. The fruit bears late summer or early autumn. Choose a site in full sun for your new pomegranate tree.
Because pomegranates need a lot of water, provide it regularly during dry spells. Pruning should only take place in spring or summer and avoid removing branches below the fruiting spurs.
If you’d like fresh pomegranate juice, buy pomegranate seeds at nurseries instead of the whole fruit. The seeds will last longer and keep their color better.
The most common way to store them is in an airtight container. But I’ve found that storing pomegranate seeds on top of a plate covered by plastic wrap works really well, too. Just make sure there’s enough space under the plastic wrap for the seeds to breathe.
These hardy bulbs love cool temperatures, so plant them where you can expect winter lows around 40 degrees Fahrenheit. Summer Crocus likes to be planted in full sun, but it also does well in partial shade. These lovely little bulbs flower from April into June. Their blooms are usually yellow (sometimes white) and range in size from 1/2 inch to 1 inch across.
They have a long bloom period, so you won’t have to replant yearly. And because these bulbs are easy to grow, you don’t need a huge bed to accommodate your planting area. Just use a half-barrel and fill it with soil up to 6 inches deep. Plant the bulbs 8 inches apart—that’s how far apart they spread in their natural habitat.
You can start them indoors four weeks prior to transplanting, but wait until all danger of frost has passed. Set out your bulbs after the ground warms above 60 degrees F., and keep the soil moist until they begin to sprout.
The Dorman Red grapevine is one of the most productive varieties available today. In fact, it produces more fruit per vine than many commercial wine grapes. And because it grows quickly, there are few risks associated with growing it.
This everbearing cultivar produces abundant, sweet, red fruit on fast-spreading, thornless canes. You can expect high yields on 2nd-year canes from mid-June through the first frost in early September.
Trellis is necessary to prevent them from trailing along the earth.
This self-pollinating variety thrives in hot and humid climates where other cultivars might struggle. Plant ” in full sun in well-drained soils.
Rubus idaeus var. strigosus ‘Heritage’ is a vigorous cultivar producing large fruits with little disease pressure. This variety grows well in containers and borders, and it is one of our most popular selections. It bears heavily throughout the season, producing small clusters of medium-sized, bright red fruit with good sugar and acid levels. These are delicious, eaten out of hand, or added to salads or desserts. They keep well into winter.
Rubus x ‘Joann J’ is one of the most popular varieties among home gardeners because of its attractive appearance and ease of growing. Its bright red berries are borne singly on long stems, and the plants produce abundant crops throughout summer. A compact shrub growing up to about six feet tall, Joan J bears large, glossy leaves and clusters of fragrant pink flowers in spring. In fall, the foliage turns brilliant orange and red.
Rubus ‘Polka’ is a vigorous, upright shrub with thornless stems that grows up to six feet tall and wide. The plant produces large clusters of small, round fruits that are bright red when ripe. This variety ripens early, maturing about ten days earlier than most other raspberry cultivars.
The flowers bloom in mid-June and continue blooming into late August, producing enough fruit to sustain pollinators throughout the summer months. In addition to being easy to grow and productive, ‘Polka’ is self-fertile and requires no cross-pollination.
Everbearing with an upright growth habit, ‘September’ reaches four to six feet tall at maturity, with an even spread. September bears fruit on second-year canes during the late summer and early autumn, while first-year canes bear fruit in the fall. In very wet soils, plants tend to produce fewer fruits. Plants grown in full sun perform better than those grown under partial shade.
The fruit is sweet, juicy, and flavorful – the taste is similar to strawberries. A single plant produces about 12 pounds of fruit per season. Fruit ripens from mid-August into October.
