These beauties from Kent were for sale at P & I; but our growers face fierce competition from Spain and Turkey.
It's prime time for soft fruit. British gooseberries have sweetened up in the sun; strawberries and these Kentish raspberries are looking tip top; these jewel-like whitecurrants are from over the Channel.
For stone fruit, expect plenty of peaches (including white-fleshed and flat), nectarines and apricots - mainly Spanish. Not long now until English plums make an appearance.
Melons are a good call in July - well priced and popular in this hot weather. All varieties available.
Outdoor-grown British rhubarb is still available.
Figs are also arriving from Spain (black), Italy (flashes of green) and France. Turkish will be along later in the year.
English peas and broad beans are now underway - although they are not enjoying the heat.
High temperatures are also a bane for UK salad growers, as lettuces tend not to grow above 30C. (Find out more here.)
Other British veg include the first new season carrots, beetroots, the first courgettes, tomatoes, Rainbow chard, baby fennel, cucumbers and broccoli. Jersey Royals are reasonably priced. Not long now until runner beans.
Sweetcorn has started from hotter climes such as Morocco.
Continental lines include the first of this season's garlic, beans (Borlotti; Coco de Paimpol etc.), coloured beets, Romanesco, artichokes, Reine Claude and courgettes.
You won't find much in the way of wild mushrooms with the exception of girolle.
I loved the look of these chillies.
On my visit, I visited a special pop-up avocado stand at Covent Garden Supply. This ingredient is in huge demand these days, overtaking oranges in the retail category. Per capita consumption in the UK has increased nearly 200% in the last five or so years.
"Just five or six years ago we would have been incredibly excited to see a single avocado recipe in a magazine - now it's daily," says Matthew Churchill of Greencell, who was behind the stand.
He explained that key varieties include Pinkerton, Fuerte and Hass (nuttier flavour; most popular).
See you in August, in time for the first English runner beans and crisp Discovery apples.
