Unusual and rare foods from winter purslane to pullet eggs, produced in the UK, are not getting a look in at the major grocery chains, they claim.
And as a result, generations are growing up without ever tasting some of Britain's finest food flavours such as borage flowers and or crystal lemon cucumbers.
Celebrity chef Jamie Oliver is among those calling for a return to great British fare such as pullet eggs - the mini eggs produced by hens before they are fully mature.
Now, delivery service Farmdrop is highlighting a dozen dining delicacies from nasturtium to Chegworth beauty apples to try and put home grown flavours back on the menu.
These foods were once sold by specialist shops, many of which have since been forced out of business by the undercutting tactics of big supermarkets.
But the supermarkets themselves rarely stock them because they are deemed too fragile to be mass transported cheaply as they do with foreign produce.
The 12 named by Farmdrop are red flash strawberries, wild garlic leaves, nasturtium flowers, winter purslane, borage flowers, ping tung aubergines, crystal lemon cucumbers, courgette flowers, dandelion leaves, pullet eggs, Chegworth beauty apples and marigold flowers.
