1. Gladiolus: Spire-Like Blooms for a Statement Garden
Gladiolus bulbs send out spire-like flowers in an array of eye-popping colors, making them a true statement plant for the summer garden. They are quite striking when planted at the back of a garden bed or along a fence or the side of your house. With a height of 3 to 6 feet (90 to 180 cm), gladioli provide vertical interest and can be used to create dramatic focal points. The key to successful gladiolus cultivation is proper planting and minimal intervention. In April, when all risk of frost has passed, dig a hole about 12 inches (30 cm) deep and 18 inches (45 cm) apart. Place the bulbs pointed end up, ensuring the top of the bulb is level with the ground. Adding a layer of mulch around the base of the plants helps retain moisture and suppress weeds. Gladioli make wonderful cut flowers, so all you need to do is wait until it’s time to cut them, then fill a vase with these summer stunners. Get gladiolus bulbs from Burpee in a mix of vibrant colors. The specific color palette available can vary seasonally, but you’ll find everything from classic reds and pinks to sunny yellows and deep purples.
Growing Tips for Gladiolus: Gladiolus bulbs prefer full sun but can tolerate partial shade, especially in hotter climates. They require well-drained soil – clay soil needs amending with compost and other organic matter. Consistent watering is essential during the blooming period, but avoid overwatering, which can lead to bulb rot. Deadheading spent flowers encourages continued blooming. Consider staking taller varieties to prevent them from flopping over, especially during windy weather. The average bloom time for gladiolus is approximately 4-6 weeks, providing a long-lasting display of summer color. Interestingly, gladiolus flowers have been used in floral arrangements for centuries, dating back to ancient Rome and Greece, where they were associated with strength and honor.
2. American Turk’s Cap Lily (Lilium superbum): A Native Beauty for Woodland Gardens
American Turk’s cap lily (Lilium superbum) is a North American native plant that produces fiery orange blooms in mid to late summer. Reaching 4 to 8 feet (1.2-2.4 m) tall it is the largest native lily to the US and grows wild in a wide range of the country. This perennial bulb is hardy in USDA growing zones 5-8 and prefers a moist, but well-draining soil. Turk’s cap lily is a perfect summer bulb for a rain garden or damp woodland landscape. Because it’s a native, this plant grows easily without any fuss as long as you plant it in the right location. If you have a shadier, wetter spot where you need to add some summer color then this is your plant! The striking, upward-facing flowers resemble a miniature turban, hence the name “Turk’s Cap.”
Key Characteristics & Care: Lilium superbum thrives in shaded areas with consistently moist soil. Amend the soil with organic matter to improve drainage and fertility. A layer of leaf mold or compost around the base of the plant is beneficial. Fertilize sparingly in the spring with a balanced fertilizer. These lilies are deer resistant, making them a good choice for gardens where deer browsing is a concern. They are also relatively pest-free, further reducing the need for intervention. Propagation can be achieved through division of established clumps in the fall. The historical significance of the Turk’s Cap Lily extends back to the 18th century, when it was highly prized by American botanists and horticulturalists. It’s more popular in the UK, but it’s gaining recognition as a stunning native plant within the United States.
3. Canna Lilies: Bold Foliage and Dramatic Blooms
The canna lily is a summer bulb garden staple. They have huge, dramatic leaves and blooms that come in a variety of bold hues. They are also easy to grow and care for. In April, once all chance of frost has passed, you can start planting canna lily bulbs outdoors in the ground or containers. Space out canna lilies in your garden for maximum impact. These are truly statement plants and look best when a single one is allowed to shine on its own. Grow canna lilies in pots on a patio or in different corners of your garden. Canna lilies like full sun and rich soil, so choose a bright location and amend your soil with compost before planting bulbs. After planting, add a layer of mulch to help retain moisture and give bulbs a strong start. Then wait for the gorgeous leaves to unfurl and the colorful spikes of flowers to bloom.
Considerations for Canna Lily Success: Canna lilies are exceptionally tolerant of heat and humidity, making them ideal for hot summer gardens. They perform particularly well in containers, allowing you to position them in the sunniest spots. Different cultivars offer a wide range of foliage colors, including green, bronze, red, and variegated patterns. The flowers come in shades of red, orange, pink, and yellow. Regular fertilization during the growing season promotes vigorous growth and abundant blooms. Be mindful of the mature size of canna lilies – some varieties can reach 6 feet (1.8 m) in height. The genus Canna has a fascinating history, with evidence suggesting that its use dates back to ancient Rome and Greece, where it was cultivated for ornamental purposes.
