PlantFiles: Sweet William
Dianthus barbatus

all dianthus are great, they are so easy to care for and provide beautifull flowers all summer, they overwinter easily in zone 5 and i agree the leaves do not even die back- they just come to life in spring. I started with sweet william years ago and had great luck so i stuck with them even when i moved, and i honestly didnt know untill last year that they were a bi-ennial plant, they overseed so easily that that i didnt notice. most of mine are kept in a bed with weedblock to keep them in nice neat rounds, otherwise they can tend to grow out of control in only a couple of years. a must have in every garden especially for new gardeners.

I have two patches that does well in partial shade - they stays pretty much evergreen and are more of a perennial - they don't really selfsow but tend to stem root themselves. They are very easy to start from seeds (I hadn't does it in years - too limited sun).

These plants thrive as a prennial here (central valley, CA). Mine have been in the ground for going on 3 years now and have just continued to spread out. They need to dead headed or they end up looking as if they have brown tips from the dried flowers (not pretty). It's mid January and I've got a couple blooms already. They'll be in bloom all Summer and well into Fall.

I love this plant and have had success for many years - until now - all the sudden my dianthus has turned brown and is dying all the way to the root. Plenty of sun, right soil, and right watering. I'm wondering about disease.

I can't imagine living without this old favorite, either - especially among large shrub and climbing roses.

Sweet William has been successfully wintersown in my zone - to see if it has been done in your zone, click on [HYPERLINK@www.wintersown.org] , go over to right column, and click on Wintersowing 2006 Database, where there are many lists for zones 3 - 10 plus Alaska. If it hasn't been done in your zone yet, experiment and see what happens - wintersowing is a "leap of faith" not just for seeds, but for antsy folks impatient for spring to come, as well. DG has a very warm circle of wintersowers in its Wintersowing Forum, so visit them, too. If you don't want to fool with damping-off fungus that often hassles indoor-sown seedlings, try wintersowing.

The relatively fat leaves and squat-ish plants of Sweet William are nicely complemented later in summer by airy, dissected leaves of cosmos growing behind, which will continue the blooms in that spot till frost.

PS - Darkness is said to increase germination of the seeds of this plant.

These hardy plants have always been a part of our landscape for longer than I remember. The original packet of seed came from Burpee Seed Company many years ago. The plants shown in my Journal are all descended from the seeds in that packet. I allow them to self-sew, and either thin them out or transplant to different beds. I also cut the mature seed pods with scissors and collect them in a jar to sprinkle in bare spots. The colors vary widely, from pastel whites, pinks and rose to burgundy and red with differing circular patterns and picoteed petals. An excellent bee and butterfly attractor, they have a very pleasant fragrance. I can't imagine a garden without them!

A beautiful flower that readily self-seeds to fill in a gap. It is one that people always ooh and ahh over. They do get heavy and like to flop after a rain. My information says they are hardy in zones 3-9, and need more shade in hotter climates. Stratification aids germination of seeds. Blooms late May to late June in my garden.

I'm not a fan of biennials but this plant "volunteered" in my garden..... Its nice though! It gets the dianthus flowers all in a cluster at the top of a long stem. Mine are pink/purple/white.... It has a fragrance.... a mix of powder and clove.... somewhat less pungent than some dianthus but spicier than a powdery one like superbus. Still has notes of the distincitve spicy scent. Must be very easy to grow. I do nothing for it. It grows (in my garden) in full sun in sandy loam.... in a garden bed that is always fertilized. It's leaves are not blue-green like some dianthus. They are green and somewhat thick compared to some. (not slender or willowy ooor grassy....).... (like alwoodi for example) Each bloom is about the size of a larger man's broadcloth shirt type button. Born in clusters (as they are) they ad to each other's show. Not my favorite flower or my favorite dianthus but puts on (fragrance and flower) and perfectly nice (simple) and cottagey show. :)

The gorgeous flowers bloom in early spring and last a long time. Deadheading brings another flush of bloom (and eliminates any shabbiness from spent flowers), although not as vigorous as the first. Definitely a must-have for my garden!

This died back to the ground here, but came up this spring '04 and is doing exceptionally well. I'm not sure if it came back from the roots or if it simply re-seeded itself. It's blooming beautifully.

This is considered a perennial here, most winters the foliage never even dies back. VERY easy to care for, and can be planted in shade, or partial sun. It does look untidey if its not kept cut back. It does re-flower here, if cut back.

These plants are beautiful! You have to watch out for whirly worms in the spring as they love the old leaves from previous years. This plant grows well on Prince Edward Island.

It did a great job of "locking down" the soil on a slope, and it's practically weed proof once established, but after flowering it needs to be cut back (unless you want seeds) since the seed heads make the area look unkempt/a total mess.

Sweet William is a biennial which acts as a perennial by re-seeding itself. If not allowed to set seed, clusters of new plants form around the old stalk.

Sweet William grows best in slightly alkaline soil and likes a warm sunny growing area. The pink, red, salmon or white blossoms appear in late spring or early summer, and are excellent cut flowers.
