Water shortages, new types of gardening and an ageing population are among the factors likely to shape gardening, according to plant development expert Gary Grueber of Cultivaris.
Grueber, who will speak about gardens of the future at the HTA's upcoming Contact conference, said there was a lot of potential for breeders.
"Water shortages will be a factor and gardens are getting smaller - urban gardening is a big issue" he said. "There are also new types of gardening, such as vertical gardens."
He said grow your own would continue to be a big topic and that an ageing population would influence gardening across Europe: "Gardening habits will change. There won't be a decline in interest but an increase; we need to ensure the right products are available."
He added: "There is so much potential in conventional breeding - we haven't even started. In my talk for the HTA, I want to discuss what the future of gardening will look like. What will the gardens of the future and the markets of the future be like and what can be expected of consumer demographics? What kind of products do breeders have to create?"
Grueber also told Horticulture Week that genetic engineering was unlikely to become a major part of ornamental plant breeding because the investment required was too great.
He added that this situation may change in the future as the technology becomes more widespread and people look for ways to create plants that are drought-tolerant or disease-resistant.
