Hey, I just stumbled upon this today. I didn't know there was a Cottage Garden Cubit until right now! Glad to find it. Cottage gardening is deffinately my style, there is very little lawn left here as I just have continued to add and expand gardenbeds year after year.
I also like a very packed full jumbled up look which is very cottage garden. I grow veggies, mostly tomatoes now although I used to grow lots more annual edibles. But I also have lots of small fruit shrubs like currant, gooseberry, really dwarf cherry trees, serviceberry, blackberries and lots and lots of blueberry shrubs. Then I have bird attracting shrubs for the backyard songbirds like crabapples, shrub dogwoods, viburnums and more.
Add the butterfly and hummingbird attracting vines and flowers, combine with things that just have pretty flowers, such as roses, daylilies, iris and lilies and its very cottage garden around here.
