Dahlia 'Lucky Number' would have to be my favorite Dahlia in my garden. It seems to look good with anything near it and has been growing alongside Echinacea 'Magnus', pink Zinnias and other Dahlias. It has bloomed for months and the flowers last a long time.
Here it is with Cupid's Dart (Catananche) growing in front of it. Both of these have withstood a lot of sun and very little water this past summer.
Another of my very favorites this summer is the Variegated Wallflower (Erysimum). The way it ages from purple to a rusty pink color makes it age perfectly with the Echinaceas behind it. The pinks of the different Echinaceas age along with the Wallflowers and look so pretty together right now.
Nicotiana 'Sensation' (it seems like everything was called 'Sensation' this year) and Pink Flower Carpet Rose. Since Flower Carpet Roses have no sent, the fragrance of the Nicotiana makes up for it.
Salvia 'Black and Blue' with Aster 'Professor Kippenburg'. I love the pop of orange from the Cosmos 'Bright Lights' in the background.
Pink Penstemon, Lantana and Lamb's Ears (Stachys byztantina).
Many of these flower combinations have been in bloom for months, making me even happier that they are together.
