The 2010 Patio collection, selected in conjunction with Royal Botanic Gardens, Kew, is a range of 20 varieties of vegetables that are easy to grow in containers and small spaces.
At the public launch of new varieties for 2010, horticultural manager Andrew Tokely said: "We are looking at targeting city dwellers but the range is suitable for all."
The range includes one variety of each vegetable that will flourish in a confined space and allow those who live in urban areas to harvest their own crop.
The Gardening Made Easy catalogue will tap a similar market — focusing on those with no previous knowledge or experience of horticulture, it will offer a range of basic varieties, designed to help amateurs overcome their fears of taking care of plants.
Sight supervisor and trial coordinator Sue Foster said: "There are a lot of people who would really like to have a go but they don't know where to start. We are trying to offer really simple plants that anyone can grow successfully."
The collection includes potatoes that can be grown in a bag, a miniature sun flower and the new Calendula 'Apricot Twist,' a bushy plant with fully double flowers and a dwarf habit.
Also new is the Sweet and Juicy fruit collection, which includes varieties like the apple Temptation.
