PGB Mentors

PGB mentors are experienced and inspirational individuals who want to share their expertise and give back to others. PGB mentors work as consultants alongside our advisory panel and working group, either sharing their knowledge directly with a designer or charitable organisation, or via our blogs, webinars and social media. Their fields range from planting and design expertise to RHS shows, landscaping and construction through to effective charitable messaging and marketing.

Chris Marchant

PGB Mentor, Partner at Orchard Dene Nurseries & Consultant
,
Orchard Dene Nursery

Chris and Toby Marchant were founding Partners of Orchard Dene Nurseries, specialist growers supplying an extensive range of 1500 plants, grasses & ferns to professional Landscape Designers. Having come from a background in 3-dimensional design, Chris turned her attention to designing with plants in 1990. Orchard Dene Nurseries went on to contribute to numerous Gold Medal winning gardens at Chelsea, including the highly acclaimed millennium garden designed by Piet Oudolf and Arne Maynard, and the magnificent Chatsworth Rock Garden designed by Dan Pearson. Whilst running the nursery for more than 30 years, Chris and Toby were also designing and implementing their own planting schemes in parallel, and believe these dual skill sets remain vital to their understanding of the market they embrace and designers they assist. Chris now spends her time collaborating with professional design practices to inspire and enliven their planting approach. She remains committed to working with plants and people in order to bring out the best in both.
