In case you’re looking for a variety of colorful flower plants for your cascading flowers for window boxes, consider some of the most common varieties and their uses. These include Impatiens and Petunias, which are summer’s workhorses and attract pollinators. Geraniums provide long-lasting color and attract beneficial insects. Sweet potato vines, a vigorous ground cover, provides a splash of color and attracts bees and butterflies.
Petunias are summer’s workhorse
If you want a plant that can survive with little care, look no further than the popular petunia. These plants thrive in warm, sunny conditions and need about six hours of sunlight per day. Grandiflora varieties produce massive flowers and can be planted in window boxes. Other excellent choices for window boxes are the smaller Calibrachoa (Million Bells) and trailing petunias.
These annuals grow about four inches tall and can reach 15 inches in diameter. They can be a great accent plant, as they spill over the edge of the window box. However, petunias need special care to avoid rot. You should make sure that they are planted in a sunny location and avoid growing them in a moist, drafty area.
Petunias are a summer workhorse. Easy to grow and versatile, these plants look great in window boxes and containers. You can combine them with other plants for a sizzling effect, or go for a classic look by combining white and chartreuse. They are also adaptable, and their trailing forms are great for cascading over rocks and patios.
The fuchsia plant is a perennial with attractive foliage that lasts until frost. The flowers bloom from early summer through fall, usually dying out after the first frost. The hardy fuchsia is a low-maintenance perennial that grows well in partial shade and moist organic soil. Its deep magenta blooms can be a combination of striped, speckled, fringed, and solid varieties. Some varieties have cascading habits, such as Wave petunia or Grandiflora.
Impatiens attract pollinators
Planting a colorful and fragrant window box is a great way to encourage pollinators. Impatiens, also called Mexican marigolds, are perfect for window boxes. Their brightly colored blooms attract butterflies and bees. They also attract late-flying pollinators, such as wasps and moths. And since they are drought and heat-tolerant, they’re a great choice for deep-shaded window boxes.
The stunning foliage of the Coleus plant also makes it a great choice for window boxes. These plants produce small flower heads that attract hummingbirds, bees, and butterflies. You can choose from two varieties, Alabama Sunset and Chocolate Covered Cherry. Begonias are a great choice for window boxes and they’re perfect for partial shade, too! Wax begonias will bloom continuously throughout the summer.
Geraniums provide months of color
Adding geraniums to a window box is a great way to add seasonal color and interest to your window display. These hardy plants belong to the Geraniaceae family, and have five petals per flower. Their flowers range in color from a deep maroon to a soft pink. There are even blue varieties, but they grow slowly and are often floppy. You can root snippets of geranium plants, and these will spread throughout your window box.
While geraniums thrive in temperatures of 50 to 60 degrees Fahrenheit (10 to 16 degrees Celsius), they can be grown successfully in colder climates. They are not as hardy in northern climates, so you should be able to find a variety that does well in your area. Geraniums do best when planted in a protected spot, and they can survive in temperatures as low as 32degF (0 degrees C) and as high as 80degF (27 degrees Celsius). Just remember to water them well and prune them well in early spring after new growth appears.
Plant geraniums outdoors in spring after the danger of frost has passed. Make sure to water them regularly to prevent wilting and rotting. If they start to get too large for their container, they may need to be repotted. Make sure you water the pots regularly, and use a well-draining potting mix. The best geranium soil is one with plenty of drainage holes and good drainage.
Sweet potato vines are a vigorous ground cover
Sweet potato vines make great ornamental plants and can be grown in window boxes or in pots outside. They can also spill over walls and cover the ground in a landscape bed. They are also popular indoor plants. Once established, sweet potato vines can be pruned to maintain their shape and can be propagated indoors year-round. If you’d like to grow sweet potatoes in your window box, there are several varieties you can choose from.
However, you should be aware of the dangers of sweet potato vines. These plants are susceptible to various pests, including whiteflies, sweet potato loopers, and the black-and-rust colored sweet potato weevil. These insects eat the foliage and sap from the sweet potato plants, and may also spread disease. Neem oil, diluted with dish soap, is an effective remedy for these pests.
If you’re planning to grow sweet potato vines in your window boxes, you can cut the top leaves to replant them. After that, plant the cutting in a jar of water. Sweet potato vines have strong roots that will appear at leaf nodes. They also come in five different colors, including green, purple, blue, and orange. In full sun, they look like maple leaves. If you choose to grow them in a shady area, their foliage turns darker green.
Petunias are a favorite of hummingbirds
Planting petunias in your window boxes will attract hummingbirds to your yard. These flowers have the perfect shape for hummingbirds. Petunias are a perennial favorite, but newer varieties may be less fragrant or contain less nectar. They are still great plants for window boxes, though. Other plants to consider are Lobelia flowers and the cardinal vine. Lobelias need consistently moist soil and can be found in many varieties.
While petunias grow well in window boxes, the best choice for shade is an annual like begonia. Their flowers are attractive and attract both hummingbirds and bees. They can grow from a few inches tall to three feet tall and are available in single and double flower forms. Depending on the variety, petunias will bloom in multiple colors from spring through fall.
Petunias are a popular choice for window boxes because they provide a sunny, moist environment for hummingbirds. However, petunias don’t do well in excessive heat. They need at least six hours of sunlight per day to thrive. For this reason, petunia window boxes should be made of soil that drains well and is moist.
A combination of flowers and foliage is the most attractive effect for hummingbirds. Coral bell cultivars, with their purple foliage, add drama, while their yellow or orange blooms provide nectar. Hummingbirds also enjoy different leaf textures, so choose a variety with staggered height and habit. Petunias are a perennial favorite and hummingbird-friendly.
Petunia seeds are easy to grow
Petunias have a low watering requirement, but they do need a location that receives plenty of sunlight. Many varieties thrive in poor soil, but you must make sure that you have enough sunlight for them to flower well. They need about 5 to 6 hours of good light each day. If you have a shady window box, impatiens would be a better choice.
You can start your petunia seeds indoors, about ten to twelve weeks before the last frost date. Start the seeds in peat pots with seed starting mix, or directly in the soil. Petunia seeds need sunlight to germinate. They grow best in full sunlight, but will also tolerate indirect light. Petunias prefer light soil with a pH level of 6.0 to 7.0.
Growing petunia seeds is not difficult, but the seedlings are slow to germinate. You can mix dry sand with seedlings in a container. Then, sprinkle the seeds evenly on the growing medium. It is best to plant them six to ten weeks before the last frost date. When planting petunia seeds outdoors, make sure to lightly press them into the potting soil. After they have absorbed the moisture, they should sprout within seven to ten days.
Wave petunias are another great choice for window boxes. They spread over the edge of the window box and can grow to 3 feet in size. Despite the name, wave petunias need minimal maintenance. After planting the seeds, make sure to water them frequently when the soil is dry. After the flowering period, they will need fertilization weekly.
