While Cress, Rocket, Dill and Thyme appear to be the most common plants, Discovery Garden fans say the Radish, Chilli and Coriander plant kits are the hardest to come by. And of the three, it's claimed that the Radish Discovery Garden plant kit is the most rare.
‘We believe they’re definitely the rarest,’ said one collector. ‘We haven’t seen many fans or collectors land one of these so far - and none have found a radish plant.
‘It’s hard to know how much they’ll be worth at this stage - but as time goes on, they will wind up on buy, swap sell groups and eBay and we will get more of an idea.
‘But maybe hundreds? Time will tell!’
So if you do come across one of the rare Chilli, Radish and Coriander plant kits, it’s worth hanging onto - you could be sitting on a gold mine!
