Inner Green says 98 per cent of stock is grown by specialist UK growers, "and we grow a lot on site".
The plant portfolio at Inner Green is comprised of plants popular in landscaping, "interesting and up and coming new plants, and those that always seem a challenge to find".
There are more than 10,000 plants in stock.
Alan Bartlett is director.
Inner Green's other business, Inner Scapes (design, construct, planting, project management, maintenance) launched 10 years ago.
