Cucamelon 'Melothria'

Melothria scabra, Mexican gherkhin, Mouse Melon

  • This year's must-have, decorative, fruiting climber, ideal for planters

If you want to be on trend in the kitchen and in the garden, join top chefs and celeb gardeners by putting the unusual fruits of cucamelon on your menu this season. This easy to grow fruiting climber performs strongly on a sunny patio or border and even better in the greenhouse, producing heavy crops of mini melon fruits tasting of cucumber with a twist of lime! Eat the grape-sized fruits fresh from the vine all through summer, but do try to save some for salads, salsas and pickles!

The vigorous decorative foliage makes this lush climber truly dual purpose - grow this trendy patio fruit on an ornate obelisk and make it a talking point feature of your summer garden. For maximum fruit production, stop main stems at 2.4m (8ft) and trim back all side shoots to 45cm (18"). Height: 2.4m (8ft). Spread: 50cm (20").

Marigold 'Tomato Growing Secret'

Tagetes patula, French Marigold

Canny gardeners have been growing white fly repelling African and French marigolds alongside their tomatoes for decades.

We’re keeping the variety name under wraps, but we’re happy to make it available to serious tomato growers. Try it this season alongside greenhouse and outdoor tomatoes - you’ll even see your tomato plants grow better and bear more fruit with our marigolds around them.
