As the warmth of summer approaches, June presents an ideal time to cultivate a riot of color and texture in your garden. This month is particularly notable for planting bulbs that will bring vibrancy and life not just to your landscape but also to your flower beds and borders through mid-summer and into fall. In this comprehensive guide, we will explore an array of bulbs you can plant during this month, focusing on their unique characteristics, care instructions, and how they can enhance the aesthetic of your outdoor space.
Gladiolus (Gladiolus spp.)
Gladiolus bulbs, commonly known as gladioli, are a quintessential summer flower. Renowned for their tall, stately flower spikes adorned with trumpet-shaped blossoms, these bulbs come in a kaleidoscope of colors including reds, pinks, yellows, and whites. Their height often makes them an excellent choice for background planting in borders or mixed beds.
When planting gladiolus in June, select a location that receives full sun for optimal growth and flowering. It’s best to space the bulbs approximately 6 to 8 inches apart to allow for their expansive growth. Gladiolus prefer well-drained soil enriched with organic matter, so consider amending your soil with compost before planting.
Water these bulbs consistently but avoid overwatering, as they are susceptible to bulb rot. Gladiolus typically bloom 70 to 90 days after planting, making them a fantastic summer harvest that can be enjoyed fresh or cut for arrangements. After blooming, allow the foliage to die back naturally before removing it, as this helps the bulb store energy for the next growing season.
Dahlia (Dahlia spp.)
Dahlias are another stunning bulb to plant in June, renowned for their bushy growth and stunning blossoms ranging from delicate pom-poms to dramatic dinner-plate sizes. Their flowers can be found in an extensive palette of colors and patterns, making them a delightful addition to any garden.
When planting dahlias, choose a location that receives at least six hours of sunlight daily. Prepare the soil by ensuring it is rich, moist, and well-drained, incorporating compost or well-rotted manure as needed. Space dahlias 12 to 18 inches apart to accommodate their growth habits.
It is crucial to keep dahlias well-watered but avoid wetting their leaves to minimize the risk of fungal diseases. Support taller varieties by staking them early in the growing season to prevent breakage. Dahlias typically begin flowering in late summer and continue until the first frost. For those who enjoy cutting flowers, these blooms hold up beautifully in arrangements.
Lily (Lilium spp.)
Lilies are timeless garden favorites with their elegant blooms and sweet fragrance. There are several types of lilies, including Asiatic, Oriental, and Trumpet lilies, each offering its unique growth habits and colors. Planting lilies in June allows them to establish before the peak summer conditions.
Select a location with well-drained soil and full to partial sun for the best results with lilies. It’s advisable to plant bulbs about 6 to 12 inches apart, depending on the variety, and 4 to 6 inches deep. After planting, water them thoroughly.
Lilies do benefit from regular watering, especially during dry spells, but they do not thrive in overly wet conditions. Deadheading spent blooms encourages further flowering and deters the plant from expending energy on seed production. Lilies can often bloom within 60 to 90 days of planting, bringing a touch of elegance to mixed flower borders or celebrated as standalone specimens.
Ranunculus (Ranunculus asiaticus)
Ranunculus, with their bright, ruffled blooms, are perfect for adding layers and texture to any garden. Known for their vibrant colors and lush foliage, these flowers thrive in cooler climates, making June planting ideal for many regions. The beautiful blooms can range from simple to complex petaled forms, enhancing visual interest in any setting.
When planting ranunculus bulbs, choose a sunny spot with well-draining soil. Before planting, soak the corms in water for several hours to encourage germination. Space the bulbs 4 to 6 inches apart and plant them at a depth of roughly 2 inches.
These flowers enjoy a consistent watering schedule, but care should be taken not to keep the soil overly saturated. Ranunculus can bloom as early as 10 to 12 weeks after planting, typically showcasing their captivating blossoms through late spring to early summer. They also make wonderful cut flowers for arrangements, adding a flair of color and character.
Calla Lily (Zantedeschia spp.)
With their distinctive funnel-shaped blooms and striking foliage, calla lilies have become synonymous with elegance in the garden. These perennial plants are often celebrated for their unique appearance and ability to thrive in various environments, making them a versatile addition to any flower bed.
Calla lilies prefer well-drained soil enriched with organic matter and a sunny to partially shaded location. When planting in June, ensure the soil temperature is consistently above 60°F. Bulbs should be planted 4 to 6 inches deep and spaced at least 12 inches apart to allow for their expansive growth habits.
They require regular watering to keep the soil moist, especially during hot, dry spells. Calla lilies will typically bloom within 12 to 14 weeks after planting, with their elegant flowers adding sophistication to both garden landscapes and floral arrangements.
Crocosmia (Crocosmia spp.)
Crocosmia brings a burst of fiery color to the summer garden, known for its arching foliage and tall flower spikes adorned with tubular blossoms that attract hummingbirds and butterflies alike. Available in shades of red, orange, and yellow, these bulbs are perfect for creating dramatic, vivid presentations in borders and beds.
When planting crocosmia in June, choose a sunny location with well-drained soil. Space the corms approximately 12 to 18 inches apart and plant them about 3 to 4 inches deep. Crocosmias are relatively drought-tolerant once established, but they benefit from consistent moisture during the growing season.
Typically, crocosmia blooms from mid-summer to fall, providing a brilliant display during a time when many summer flowers have faded. Their striking appearance is not just a feast for the eyes; their nectar-rich flowers provide sustenance to pollinators, making them a beautiful addition to any biodiversity-focused garden.
Freesia (Freesia spp.)
Freesias are renowned for their enchanting fragrance and gorgeous trumpet-shaped flowers, typically found in a variety of vibrant colors. As a tender perennial, planting them in June allows them to thrive during the warm summer months, producing stunning arrays of flowers.
For successful freesia planting, select a spot receiving full sun to partial shade. The bulbs should be planted about 2 inches deep and 4 to 6 inches apart in well-drained soil. Freesias prefer slightly acidic to neutral pH levels, which can be amended through compost.
Watering should be consistent but moderate; avoid letting the bulbs sit in waterlogged soil, as this can cause rot. Freesias generally begin blooming in about 10 to 12 weeks post-planting, making them a delightful addition to flowerbeds and cut arrangements alike. Their intoxicating scent, paired with vibrant colors, can elevate any summer gathering or event.
Iris (Iris spp.)
Irises are celebrated for their intricate blooms and striking presence in the garden. Available in an array of colors and styles, from dramatic bearded varieties to elegant Japanese irises, these bulbs can serve as wonderful focal points in a diverse landscape.
When planting irises in June, select a spot that offers ample sunlight and well-drained, fertile soil. It is advisable to plant them at a depth of about 1 to 2 inches, with the rhizome’s top exposed to allow for adequate air circulation. Space the plants at least 12 inches apart to promote healthy growth.
Irises typically bloom from late spring to early summer, producing an explosion of color that attracts bees and butterflies, enhancing garden biodiversity. After blooming, deadheading spent flowers encourages continued vigor in the plant, paving the way for a robust flowering process in subsequent years.
Allium (Allium spp.)
Allium, known for their globe-like clusters of flowers on tall stalks, add an architectural element to the garden that’s hard to ignore. These bulbs are available in varying heights and shades of purple, white, and blue, and are notorious for drawing pollinators.
When planting allium bulbs in June, choose a well-drained sunny location, ideally with loose, organic-rich soil. Plant the bulbs approximately 3 to 6 inches deep and about 6 to 12 inches apart. This spacing allows for the mature diameter of their flower heads.
Alliums are drought-tolerant once established, requiring minimal watering apart from natural rainfall. They typically bloom in late spring to early summer, standing tall in the garden and providing a burst of color amidst the foliage. Moreover, alliums make exceptional cut flowers due to their longevity in arrangements.
Anemone (Anemone spp.)
Anemones are wonderful bulbs that often surprise gardeners with their colorful, delicate blooms. With various types available, including the popular Japanese and windflower anemones, these bulbs add softness and ethereal beauty to flowerbeds.
When planting anemone bulbs in June, select a spot with partial shade and well-draining soil. Plant the bulbs at a depth of about 2 to 3 inches and space them 8 to 10 inches apart. Keeping the soil consistently moist is critical, especially as they start to emerge.
Depending on the variety, anemones can bloom as early as late spring and continue through the summer. Their charming flowers are perfect for wildflower gardens or mixed arrangements, enriching your space with delightful textures and shades.
Daylily (Hemerocallis spp.)
Daylilies are incredibly resilient and adaptable perennials known for their stunning blooms and ability to thrive in various environments. Each flower lasts only a day, but they produce numerous buds, ensuring that your garden remains vibrant throughout the summer.
When planting daylilies in June, choose a sunny or partially sunny location with well-drained soil. Space the roots 18 to 24 inches apart since they spread over time and require ample room to flourish. Plant the roots at a depth where the crown is slightly above the soil line.
Daylilies exhibit low maintenance needs and can endure heat and humidity, making them suitable for a range of growing conditions. They typically flower from early summer to fall, varying in colors from yellows and oranges to deep purples, adding a cheerful element to any garden display.
Begonia (Begonia spp.)
While usually appreciated for their bright foliage, begonias produce delightful flowers that can brighten up shady areas of your garden. These plants are suitable for containers or as border plants and thrive in partial shade, making them ideal for areas lacking direct sunlight.
When planting begonias in June, select a shady spot with rich, well-drained soil. Plant the tubers 1 to 2 inches deep with the growing tip facing up. Space them 12 to 18 inches apart to allow for proper air circulation and growth.
