Which listed landscape designers show their work online?
Portfolio sites are shown on 17 of the 18 listings here. In design the portfolio is the product, so it carries more weight than in other trades. Look for photographs of built work next to the renders, and for a project photographed in more than one season, since a garden that only looks good in July is a half-finished idea.
