Dianthus are plants with feathery silver-green or blue-gray leaves that form a tight mound or mat and can be perennial, annual, or biennial. Dianthus flowers range in height from two inches to two feet above the foliage, leaning a bit lazily toward the light. The blossoms are normally only about an inch across and have a ruffled edge that appears like it was trimmed with pinking shears, yet vigorous plants produce dozens of stunning flowers at once. Snow white, blush pink, brilliant magenta, or bicolored dianthus blooms with a flamboyant contrasting center or picotee edge are all possibilities. The delicate blue of ‘Diana’s Blueberry Hybrid’ is beautiful.
Types:
The majority of plants are perennial, however others are biennial or annual. Pink perennials are evergreen or semi-evergreen perennials. The common name comes from the frilly edges of the petals, which resemble pinking shears when cut. Sweet William is a perennial that is usually grown as a biennial or annual. Florists love carnations (Dianthus caryophyllus) because of their long stems and long bloom time.
Color and characteristics:
Flowers with frilly petals are solitary, semi-double, or double. They’re available in almost every color except blue, as well as patterned bicolors. The foliage is strappy and grass-like, with green, blue-green, or silver-green hues.
Toxicity:
Some people may have slight skin irritation from Dianthus foliage, which normally lasts only a few minutes. If swallowed, the plants might be somewhat hazardous to pets.
How many years do dianthus last?
How long does dianthus last? Year after year, these plants will come back. Deadheading on a regular basis can help to promote this growth. The plant’s blossoms, on the other hand, usually only survive 8 weeks.
Is there an annual dianthus?
The non-hardy cousin of perennial Carnations, Cottage Pinks, and biennial Sweet William is annual Dianthus. They form dense, carpet-like mounds with single to double disk-like flowers in colors of red, pink, white, and bicolor that are faintly aromatic. They’re a great choice for cool, sunny regions and containers as a bedding plant. They have the ability to self-seed in the garden and prefer neutral to slightly basic pH soil.
Will dianthus survive winter?
Annual dianthus tolerates minor frost well, but strong freezes can be damaging. Dianthus can be grown as a winter annual in milder climates.
Is Firewitch dianthus a perennial?
With highly fragrant rose-pink flowers and gorgeous gray-blue evergreen foliage, Dianthus Firewitch is a wonderful Garden Pink. The Perennial Plant Association (PPA) had its annual meeting in 2005. Perennial plant that is drought resistant or tolerant (xeric).
Do you have to deadhead perennial dianthus?
- To produce the most amount of flowers throughout the year, the plant will require full sun. It’s possible that the plant won’t produce as many blooms if it doesn’t get enough sunshine (if any at all).
- Deadheading annual dianthus is extremely crucial to keep the plant from generating seeds and spreading. Do not deadhead if you want to collect seeds to develop more plants or if you want the plant to spread spontaneously in your garden.
- Using rubbing alcohol, sterilize the shears or scissor. This reduces the danger of disease transmission from plant to plant.
- You may decide to trim the blooms before they become sad-looking. That’s fine, and you’ll be able to appreciate the cut flowers in an arrangement!
How do you get dianthus to rebloom?
As the blossoms droop and wilt, pinch them off. To improve the possibilities of the dianthus reblooming, remove the old flower head above the uppermost set of leaves to avoid the production of seeds. After the first flush of flowering in early June, cut back mounding dianthus kinds.
How do you plant dianthus in the ground?
Dianthus can be cultivated from stem cuttings, seeds started indoors, or simply sown into the soil.
Start seedlings inside 2-8 weeks before the last frost date in your location. Sprinkle seeds over the top of a light, loamy soil mix before covering with a little layer of dirt.
To keep the soil moist and warm, cover the container with a cloche or plastic bag. Move seedlings into their individual pots after they have 2-3 genuine leaves. Once they reach a height of 4-5 inches, transplant them outside.
Once all threat of frost has gone, straight sow seeds outdoors to a depth of 1/8 inch. Keep the soil moist, and thin to 8-12 inches apart after they have 2-3 leaves.
Cut several non-flowering stems from the parent plant right below a leaf joint to start stem cuttings.
Trim the lower leaves from the stem, leaving 4-5 sets of leaves at the top. Dip the base in hormone rooting powder and plant it up around the perimeter of a light potting soil container.
Fill a plastic bag halfway with water and secure the top with a twist tie. Set in a shady position in the garden that gets early sun but is protected from the scorching afternoon sun.
In around 4-5 weeks, stem cuttings should root. Remove the dirt ball from the cuttings and gently separate them, then pot them up into individual containers.
Overwinter in a warm, sheltered area away from frost and freezing weather. Once the soil has warmed up, plant out in the spring.
