The Indoor Garden Design director has been working backstage at Glastonbury and at London Fashion Week installing houseplant displays.
He says while events like this would previously have dressed areas with cut flowers, they now use houseplants.
He added: "I’d love to work with garden centres to improve boring ranges and boring displays of houseplants."
He said: "It’s rare for the younger generation to have access to outdoor space so houseplants are a good way for them to garden."
Ikea have led sales of houseplants, while shops such as Habitat and Urban Outfitters use them in displays. Drummond said florists were stepping up with new ranges but garden centres were lagging behind.
Drummond says hanging plants and ferns are big. He says on the commercial side he has never been so busy, and people are regularly showing him photos of their houseplants grown at home.
The top three plants in the efig office plant of the year were rhipsalis, zamioculcas and euphorbia tirucalli. Longlisted were pachira, peperomia and stags head.
Drummond has a book titled At Home with Plants published by Mitchell Beazley in April 2017.
