Marigold 'French Vanilla' F1 Hybrid

Tagetes erecta, African Marigold

 Customer Rating
A triumph in plant breeding! A real creamy white flowered Marigold and at last something different in the colour spectrum from oranges and lemons. Flowers are pure in colour, 7.5cm (3in) across and prolific too. There is also a master stroke - 'French Vanilla' has less of the pungent Marigold smell. A definite improvement! Use them in formal or informal bedding, where they will contrast superbly with other bright or pastel flowers. A refreshing plant for the patio container too. Height: 30-38cm (12-15in).
