The two best edible roses that we know of are:

1. Rosa Rugosa – these are bush varieties that are perfect as 3-4′ tall, round shrubs (buy plants here); and
2. ‘The Generous Gardener’ – a climbing variety, bred by renown rose breeder David Austin, that grows great on a trellis, fence, or arbor (buy plants here).
