Start with tall backbone plants like hollyhocks and Joe Pye Weed (Eupatorium purpureum). Perhaps a vine, like Boston Ivy (Parthenocissus tricuspidata), would give you more privacy along the chain link fence. Then add some mid-height shrubs, like Deutzia gracilis and shrub roses. You have a variety of tall perennials to choose from in your area: Delphinium, Foxglove (Digitalis sp.), Penstemon digitalis 'Husker Red' and Phlox are standard cottage garden favorites. For something a bit different, try Malva alcea 'Fastigiata' (pink flowers) and Boltonia asteroides (white or pink flowers). Fill in the front of the border with the perennial herbs you like to use in cooking, and Scented Geraniums (Pelargonium sp.). For edging, try Ajuga, Fleabane (Erigeron) and/or Lamb's Ears (Stachy byzantina). You'll find your own cottage garden favorites as you go along. Have fun!
