Marigold 'Striped Marvel'

Tagetes patula, French Marigold

Raised by a Scottish T&M customer. We are delighted to introduce such a refreshing break in colour.

The bushy, uniform plants produce masses of flowers, excellent for bedding and particularly good for cutting, lasting well in water. Occasional all yellow bloom produced through climate stress. Height: 60-75cm (24-30in).

Culinary note: The citrus tasting flowers have many uses, try them in salads, sandwiches or seafood dishes too. For more details about edible flowers click here.

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. But we know that some marigolds make better white fly deterrents than others, and we've discovered the best there is! 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.
