Dianthus flowers are easy to grow and bloom in a range of shades. They also attract a wide variety of pollinating insects and butterflies to your garden.
Dianthus can be grown as annuals, biennials, or perennials. They are available in more than 300 varieties and can thrive in zones three to nine.
If your garden is shady for most of the day, it is possible for dianthus to thrive. This can include areas where there is not enough sunlight to grow other plants but where you do have dappled light through a tree canopy or buildings that cast shadows on the ground.
Dianthus can also be a good choice for planters where the soil does not dry out too quickly, but should not be overwatered. Too much water can cause the leaves to turn yellow and increase your risk of root rot.
A neutral to slightly alkaline soil (pH 7 or above) is recommended, but if you have a very acidic soil, adding a handful of lime per square metre will help your dianthus plants flourish.
Plant your dianthus seedlings in spring, about 30 centimetres apart in a sunny, well-drained spot. Once they are established, feed them a balanced fertilizer every six to eight weeks during the growing season.
Depending on your climate and growing zone, dianthus may thrive in partial shade or full sun. It’s a great plant to use in containers and window boxes for a touch of romantic texture and color.
They’re also popular bedding plants in the garden and can be mixed with other flowers for a cottage garden look. Their sweet spicy fragrance can entice butterflies, hummingbirds and other pollinators to your garden.
Some of the most common varieties are ‘Eastern Star’ and ‘Neon Star’ which have attractive foliage and eye-catching flowers. They can decorate your garden for weeks at a time.
These plants need at least six hours of sunlight per day and can handle dry soil or waterlogged conditions. They are fuss free to grow and require minimal care once established. However, they are susceptible to rot, fungus, and mildew so be sure to maintain the correct balance of water and fertilizer.
If you have partial shade in your garden, dianthus are a good choice. They are tolerant of both full sun and partial shade, but they need to be planted in alkaline soil that drains well.
Dianthus are also a great choice for container gardens. They thrive in pots, but you need to water them sparingly and avoid overwatering.
Most dianthus are perennials and grow for two years, but some varieties are biennials. These plants bloom the first year and then die off, but they leave behind seeds that can be used to plant next year.
The flowers of dianthus can be very pretty and add color and fragrance to your garden. Many dianthus bloom in shades of white, pink, red and purple.
They can be grown as annuals, but you can save money by purchasing them in flats and planting en masse in the front of your shade garden. They’ll provide months and months of colorful blooms, only stopping to rest during the heat of summer.
Dianthus is a great choice for planting in pots and containers. These perennials can be grown in full sun or part shade, but they need a soil that is well-drained.
They also grow successfully in hanging baskets and window and planter boxes. If you’re growing them in a container, use a premium-quality potting mix with water-storing crystals to improve moisture retention in summer.
These plants can also be propagated from stem cuttings. You can harvest cuttings after the flowers have died in the late summer or early fall.
To avoid fungal root rot, dianthus needs well-drained soil and a neutral pH (slightly alkaline). Add a handful of garden lime per square metre during your preparation.
Depending on the variety, dianthus can be annuals, biennials or perennials. They usually bloom once in a season, but they can also produce richly fragrant flowers year-round. Some species can grow to three feet tall. Typically, they grow best in full sun, but they will tolerate partial shade as well.
