I am a person who can never have too many Dianthus varieties. My Tiny Rubies have become a favorite in my Dianthus collection. One patch is about 18 inches across now.

No, Petite is a different variety. I just bought it too. It's much more compact and, although I haven't seen the blooms yet, I believe the flowers will be shorter too. I'm interested in putting Petite in my paving stone cracks too, so post how it does for you. I just added an entry for Petite.

I just purchased a plant similar to this, but the cultivar name is 'Petite', common name 'Petite Dianthus', in the "Stepables" line:


Is this the same plant?

I hope it does well between the stones in my pathway!

Short 2" - Plant 12" apart. A cushion of 1" foliage, covered with brilliant tiny double pink flowers.

This is one of the cutest little plants, with foliage that almost looks like a little green wig. The foliage sets off the light pink flowers very well. It does need very sharp drainage (it's on a steep slope) here in rainy Oregon to survive. It's a little hard to get started sometimes but my clump is now 1.5 feet across after 2 years. I'm going to try dividing it next fall.

I bought some of these this year that I found mixed in with the regular sized Chedder Pinks at Lowes. They are really adorable. They are like itty bitty miniature Chedder Pinks. The regular sized Chedder Pinks do well for me and come back strong as long as they aren't in strong afternoon sun so I'm hoping these will too.
