I staggered six of the Pink Cheddar plants at the base of my back porch in a 10" L x 3" W bed. Each time that we walked out the door we were greeted with a fragrance so sweet and intense that we spent most of the Spring and early Summer dining on our porch. Included in this bed were six fuschia colored impatients, three Aztec Lilly bulbs, and two Snap Dragon plants. When friends and family dropped by, without fail, they complimented both the aroma and the beauty of this small but elegant flower bed.
Sadly, the impatients are the only thing still blooming in this bed, now that it is mid-August. We can hardly, wait until next Spring to once again enjoy the beauty and aroma of our Pink Cheddar, as they were well worth the $5.00 per plant we paid to have them.

Attractive, low-maintenance, wonderful scent, and comes back year after year. One of my favorite flowers.

We planted these last year and they just keep blooming and blooming over and over again. Absolutely beautiful. Low maintenance. Non-invasive.

Chedder pinks form a mat of narrow, gray-green foliage spreading up to 16-inches wide. The fragrant, 1-inch flowers are produced in mid summer and have slightly fringed petals. Many cultivars are available creating a wide variety of colors.
