Which listed landscape designers show their work online?
Portfolio sites are shown on 23 of the 24 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 at least one project on a site like yours: the same slope, the same soil, the same shade.
