When working in a limited space, it can be important to choose plants and designs that serve multiple functions. Although I’m primarily interested in agriculture and food production, my garden space belongs to my in-laws, who are more concerned with aesthetics: I find myself working at the intersection of edibles and ornamentals in order to satisfy both of these ideas about the space.
Because I work mostly with trees and shrubs, I take inspiration primarily from the Edenic “food forest” concept in permaculture. However, in terms of vegetable gardening, I’ve learned much from emulating the French potager-style ornamental kitchen garden. In essence: I try to make food production look beautiful.
This means choosing the fruiting trees and shrubs with the most exuberant and unique blossoms, and the vegetables with the most interesting foliage and harvests. It also means training plants into aesthetically pleasing forms: Sometimes this can come at the cost of production, but compromise between these values is constant when working in a limited space.
In integrating ornamental floral cultivation into productive spaces, it’s important to know which flowers are edible or useful in some way and which are not: The edible landscape should preferentially hold plants that serve a function. Edible, medicinal or useful flowers should take priority over those that are merely pleasing to look at or are poisonous.
This approach has benefits beyond the aesthetic: My garden is always buzzing with a diversity of pollinators and beneficial insects. It’s become a sort of agro-ecological habitat space, rather than a tilled field with rows of crops.
In terms of selecting plants, options abound. Decide what you like to look at, what can grow in your climate and microclimate, and what you will realistically use. In short, cultivation of edible ornamentals is ideal for urban or suburban farmers who want to use the garden space as both a place of beauty, and a place of production.
Here are some edible flowers you might consider.
1. Toscana Strawberries
These pink-flowering strawberries were winners of the 2011/12 FleuroStar Award in Plant Breeding.
2. Japanese Flowering Quince

4. Tricolor Variegata Chili Pepper
