My wife and I are always eager to try a plant that has the reputation of being a gorgeous ornamental as well as great hummingbird and/or butterfly plant. One such plant we have added to our gardens is Sweet William. Since Sweet William has long been a favorite of Georgia gardeners, I don’t know why we had not planted it before.
Sweet William is a member of the carnation family. It grows from five to 36 inches tall. The flowers are arranged in tightly packed bouquet-like clusters comprised of upwards of 30 or more blooms. The plants serrated petals ranging in color from purple to white, red, pink, or variegated. On top this, the plants easily hybridize and produce a wide variety of other color variations.
Sweet William blooms in the Peach State from late spring until the first autumn frost. During this blooming period, individual plants can be encouraged to continue producing blossoms by deadheading.
The old-fashioned garden favorite is native to Europe. Nobody knows for sure where the plant got its name. One of the most popular theories is it is named for England’s eighteenth century Prince William. Others suggest the floral beauty is named for William Shakespeare. I guess we will never know the answer to this quandary.
You can establish Sweet William in your garden from either seed or seedlings. If you plant seeds in spring to early summer, or set out plants in September or October, you will have to wait until the following spring to enjoy their showy blossoms. It you do not want to wait that long for the plant to blossom, you might want to consider buying plants and transplanting them to your garden soon after the spring’s last frost. In addition, if you sow seeds in the fall, they will germinate into plants that will bloom the following year.
I should mention, if you allow Sweet William plants to go to seed, they will readily reseed themselves. That being the case, they will quickly spread throughout a garden.
Sweet William will grow in a variety of soil types but seems to do best in well-drained, slightly alkaline soils.
In the spring of 2019, my wife sowed Sweet William seeds around one of our birdbaths. Only one plant produced a single flower last year. However, the plants overwintered and this spring (2020) rewarded us with an abundance of pink, red, and white blossoms.
For my wife, this floral show brought make memories of the Sweet Williams blooming in her grandmother’s garden years ago. In addition, they enabled me to take some stunning pictures of cardinals, thrashers and other birds visiting the birdbath to bathe and drink. The contrast between the birds’ plumage and the colorful flowers is stunning.
As for pollinators, as you can see from the accompanying picture, butterflies are already partaking in the nectar found in each Sweet William blossom. Hummingbirds and native bees have also been seen visiting the plants.
That being the case, this experimental planting seems to be a success.
