Ipomoea purpurea 'Crimson Rambler': flowers

Ipomoea purpurea, known in English as morning glory and in French as gloire du matin or ipomoée pourpre is an annual vine native to Mexico and Central America. It bears numerous showy trumpet-shaped flowers, about 10 cm across, in purple, pink, or white.

This is another one of those misleadingly labelled cultivars. To me this is not crimson, it is fuchsia. It's still pretty, but it would be easier to plan the garden if people didn't give plants misleading names and descriptions.
