Wild Flowers – Monty Don In his revival campaign, Monty Don finds out that you really do reap what you sow. Since the first half of the 20th century, 98 per cent of wild flower meadows in Britain have been lost - a statistic that which Monty finds shocking. He passionately believes that it’s not too late to do something about this and gardeners all over the UK can grow our beautiful native wild flowers. Front Gardens – Joe Swift In the past, our front gardens were highly valued and we used them to show off our gardening prowess, but sadly over time, front gardens have been paved over for parking and turned into a no-man’s land between the street and front door. Joe Swift is determined that we return our front gardens to their former glory.

Topiary – Rachel De Thame Today, topiary is mostly seen as the preserve of stately homes and formal gardens, out of reach from the rest of us. Rachel de Thame however, thinks that it’s time that this great tradition of trimming and shaping plants returns to all our gardens. Roof Gardens – James Wong James Wong is up on the roof for his revival.

Cottage Gardens – Carol Klein As a passionate plantswoman, Carol Klein wants us all to embrace one of the most iconic and quintessentially British styles of gardening in her revival – the cottage garden. House Plants – Tom Hart Dyke Plant hunter and gardener Tom Hart Dyke is championing house plants in his revival. House plants were once revered by the Victorians but now they are much maligned, seen as dull and boring, something you would associate with being forgotten on a windowsill or gathering dust on your granny’s sideboard. As a plant hunter, Tom wants us all to fall back in love with the house plant, and hosts his campaign from the Glasshouse at RHS Garden Wisley.

Cut Flowers – Rachel De Thame In her revival, Rachel de Thame investigates the decline of Britain’s cut-flower industry. On her campaign she visits New Covent Garden and discovers that 90 per cent of our cut flowers are imported. She also meets a man in Cumbria who has dedicated his life to growing sweet peas. Cut flowers are big business and £120 million a year is forked out on wedding flowers. This is something close to Rachel’s heart, as she recently arranged the flowers for her daughter’s wedding and showcased the flowers she is passionate about bringing back into all our homes. Trees – Joe Swift Today only 2 per cent of Britain is covered in ancient woodland and, in our gardens, we’ve fallen out of love with trees, which is why they are the focus of Joe Swift’s revival. He loves them and as a garden designer, trees are the first things he considers when laying out a garden.

Fantastic for privacy and screening, backdrops, focal points, fragrance, flower and foliage, they have been overlooked and ignored for too long but that is about to change. Matt thinks they can give a garden so much and in his revival he wants people to rediscover and appreciate the importance of this amazing group of plants.

Ponds – Charlie Dimmock Ever since she was a young girl, Charlie Dimmock has been fascinated by water and, in her revival, wants us all to celebrate water and wildlife in our gardens.

Stumperies – Chris Beardshaw In his revival, Chris Beardshaw wants to return a Victorian curiosity – the stumpery - to our back gardens.

Christine Walkden has always loved this decadent style of gardening and wants it back in our gardens.

Herbaceous Borders – Chris Beardshaw The herbaceous border is a truly iconic British garden feature. The number of perennial plants required, the intricacies of the designs, space required and extensive maintenance, all contributed to the herbaceous border falling out of favour with gardeners in recent years. Chris Beardshaw believes that this trend can be reversed and that these incredible displays of floral fireworks should return to our gardens once more. Kitchen Gardens – Alys Fowler Grow your own has been in full swing for the last few years but Alys Fowler wants to revive the original concept of the kitchen garden, not just the allotment or veg patch at the bottom of the garden.

Toby Buckland reveals there is so much more to grass than meets the eye. On his revival he discovers the Victorians' passion for ornamental grasses with a visit to the Royal Botanic Gardens at Kew; he attempts to rebrand grasses to deal with their complicated, tongue-twisting Latin names, which often put gardeners off; and he meets a modern-day plant hunter who travels the world in search of unusual and exotic grasses.

He meets a group of gardeners at one of the country's only chemical-free community wildlife allotments and encourages the people of Sheffield to grow wildflowers in their gardens to attract pollinators by giving them a taste for flower flavoured honey.
