Expert grower and plantsperson Sarah Raven is the woman to ask about trends in plants and horticulture. Below she explains what were the garden trends over the last year and looks to 2023 to predict what's to come in gardening.
Garden trends from 2022
There were three main things I saw becoming more and more popular in 2022.
Drought-tolerant plants
Firstly, of course after the July and August heatwaves we just had, it was drought-tolerant plants. Things such as scented-leaf pelargoniums (‘Attar of Roses’ is the very best), gazanias, and arctotis. These all hail from South Africa in their wild forms and grow and flower well with heat and drought, still remaining beautiful.
Biodiversity
Biodiversity was very much at the forefront of people’s minds when plant-selecting. This theme has always been popular with our customers - who tend to be nature lovers -and it has become even more so with COP, climate change and species-loss so much in the news. I was repeatedly asked while teaching to give advice on what were the most bird-friendly things people could easily grow, and we saw sales of grains such as panicums and wildflower mixes, as well as small garden fruit and berry-bearing trees (amelanchier, crab apples and hawthorn) rocket.
Small gardens
Small gardens and what to grow for a small space outside the back door or window has also gathered momentum. That's elegant, long-season, super-simple plants, without needing much skill, time, or knowledge to make them grow well and look good. I think this is why hydrangea breeding has gone crazy, with glamorous and slightly crazy doubles, as well as rich and glorious colours appearing.
Garden trend predictions for 2023
Nemesia ‘Lady Lisa’ is a fabulous rich coloured container plant, which is drought resistant and exceptionally reliable, flowering at Perch Hill from May to October this year. If it stops flowering prolifically, give it a gentle haircut, feed, and water and off it will go again.
Salvia guaranitica varieties are a little more reliably hardy than ‘Amistad’, and flower from June to November. These are brilliant for pollinators and as companion plants. There are new ones emerging like the beautiful soft sky blue ‘Argentina Skies’.

Dahlia ‘Dalaya Aruna’ is going to be huge, and the lovely Dahlia ‘Josie’ by my predictions. Compact dahlias, suited to growing in containers in general will be popular. People’s gardens are on average getting smaller, and luckily that’s being catered for by the huge dahlia breeding that’s taken off in the last five or so years. Dahlias will flower for five months, continually covered in flowers to admire — and pick to keep them flowering.

Ornamental sweet potatoes (the Ipomoea batatas such as ’Solar Tower Black’) take the versatile prize and I’ve totally fallen for them this year. I first saw them growing as houseplants in Paris, around those huge studio style windows maybe 20 years ago and felt inspired. They’re equally good growing up over teepees and arches outside. We used them this year as the dramatic, but super-easy backdrop to tender perennial climbers such as thunbergias.
That takes me on to the Black-eyed Susans which have been turned into a glamorous, yet still dead-easy and reliable family of plants. There are now delicious terracotta-coloured ones, soft pinks, whites, apricot and amber, as well as the straight up (and to be less interesting) plain orange and yellows. These are fine growing in a dry, exposed place even on a balcony in a high-rise and they flower right into winter. They’re hard to beat.
I also think cut-and-come-again salad leaves such as ‘Wasabi’ mustard which you can’t buy in the supermarket will be popular. They are super-easy to grow, one group cropping more and more leaves over a good 5-6 month stretch. They make even a bowl of ‘Little Gem’ sparkle.
