Cafe Au Lait Dahlias win every popularity contest, so why not create a mix with five of our favorites! From creamy taupes to hot pink, there is a reason why these huge dinnerplate varieties always steal the show. Blooming midsummer through fall, dahlias arrive fashionably late to the party, coming in when other flowers are fading. They tower in our garden beds, sometimes needing stakes or trellises to offer that bit of support they need.
