Top 6 Sweetest Strawberry Varieties to Grow in the UK

The sweetest strawberry varieties grown in UK gardens tend to share a few traits: smaller berries, thinner skins, and flavours that build on the palate rather than hitting once and fading. Marshmello, Malling Centenary, Sweet Eve, and Hapil are the most consistently recommended by growers who put taste above yield.

Now, sweetness is not down to genetics alone. Sun, watering, soil, and the moment you pick all play their part, and I will come to those at the end. But starting with the right variety gives you an enormous head start, so here are six of the sweetest strawberries I would happily grow in any British garden.

Marshmello

Marshmello is a relatively new arrival that has shot up the rankings among growers who put flavour first, and I count myself among them. It gives you medium to large berries with a remarkably high sugar content and a soft, almost creamy texture, so the name is well earned. It is a main-season variety, fruiting from mid-June through July, and the berries are bright red and glossy. They do soften quickly once ripe, which is exactly why you will never find them in a shop, and exactly why they are so good eaten straight off the plant. Give it full sun, keep it well watered while it is fruiting, and handle the fruit gently at harvest because it bruises in a heartbeat.

Malling Centenary

Bred at East Malling Research in Kent to mark the institute's hundredth anniversary, Malling Centenary pulls off something unusual: it delivers on sweetness and yield at the same time, where most varieties manage only one or the other. The berries are large, conical, and reliably sweet, and crucially they hold that sweetness even through a cooler summer, which makes it one of the safer bets for our climate. It carries good disease resistance too, particularly to verticillium wilt. Space the plants 35cm apart, replace them every three years for the best crops, and give them a potash feed in early spring.

Sweet Eve

Sweet Eve is an everbearer, which means it keeps going from June right through to October. The berries are smaller than the main-season types but intensely sweet, with a lovely complex flavour that carries a hint of wild strawberry. It was developed in the Netherlands and takes happily to our climate. The extended season is its real charm: a single picking might not fill a punnet, but that steady trickle of perfectly sweet berries over four months adds up to a proper harvest. Remove the first flush of flowers in spring to build stronger plants and a better autumn crop, and feed fortnightly with tomato fertiliser while it fruits.

Hapil

Hapil is a Belgian variety that has been a fixture in British gardens for decades, and there is a quiet wisdom in that. It is not flashy or fashionable, but it turns out some of the sweetest berries you can grow. This is the flavour people mean when they say strawberries used to taste better. The berries are medium-sized and a touch paler than some modern sorts, juicy and soft when fully ripe, with a balanced sweetness that never tips into cloying. It also does particularly well on lighter soils, where many varieties sulk. Mulch with straw to keep the fruit clean and ward off grey mould, and replace your plants every three years.

Cambridge Favourite

Cambridge Favourite has been grown here since the 1940s, and you do not last that long without good reason. It is easy, reliable, and sweet. Not the very sweetest on this list, I will admit, but consistently good whatever the season throws at it. The berries are medium-sized and pale red when ripe, sweet with a little tang that gives them character. It is also about the most forgiving variety I know for a beginner, coping with so-so soil and erratic watering without ever throwing a strop. It does throw out a lot of runners, so either snip them off to channel energy into fruit, or peg them down and raise yourself some free new plants.

Honeoye

Honeoye is the one for the impatient among us. It is an early-season variety that can start fruiting in late May in southern England, weeks ahead of nearly everything else. The berries are large, dark red, and very sweet once fully ripe, but timing is everything here: pick too soon and they taste sharp, yet leave them until they are deep red and they are outstanding. Originally American, it has settled into British conditions beautifully and is easy to find from garden centres and online. Protect those early flowers from late frost with fleece, and resist the urge to pick until the berries have darkened right through.

How to Maximise Sweetness

Whichever of these you settle on, a few habits will push the sweetness higher still, and they cost almost nothing. The biggest lever by far is sun: strawberries want at least six hours of direct light a day, and more sun simply means more sugar, so give them your best south-facing spot. In the few days before you pick, ease off the watering a little, which concentrates the sugars; just do not let the plants bake dry completely. Pick in the morning once the dew has gone but before the heat builds, when the berries are fully ripe and still cool. A high-potash feed such as tomato fertiliser, applied from early flowering, encourages flowers and sweetens the fruit. And remember that plants decline after about three years, so keep raising young ones from runners or buy in fresh stock, because young plants give the sweetest berries of all.

Frequently Asked Questions

Why do home-grown strawberries taste so much better than supermarket ones?

Commercially grown strawberries are selected for shelf life, firmness, and uniformity — traits that do not correlate with sweetness or flavour depth. Home-grown fruit is eaten at peak ripeness, within hours of picking, which is when sugar and aroma compounds are at their highest. The variety matters too: the six varieties in this guide were chosen precisely because commercial growers rarely bother with them.

What makes garden strawberries sweeter?

Plenty of sun during fruit development, good soil preparation, consistent watering without waterlogging, and letting fruit fully ripen on the plant rather than picking early. My guide to strawberry soil covers how to create the conditions that produce the sweetest results. A potassium-rich feed during flowering also measurably improves sweetness.

Which of these sweet varieties also yields well?

Malling Centenary stands out for combining genuine sweetness with a respectable yield. If yield is a higher priority than flavour intensity, my guide to the highest-yielding varieties covers the options that produce the most fruit — some of which are also surprisingly good to eat.

How does Mara des Bois compare to the varieties in this list?

Mara des Bois would sit near the top of a sweetness ranking, but it was left out of this list because it is everbearing rather than a summer-fruiting type and deserves its own guide.
