T&M own breeding. At last! Variegated climbing Nasturtiums. Available in a balanced mixture of yellows, reds, creams and peach/pinks with foliage which is attractively marbled and striped with cream, against a light green background. They make fantastic, dramatic container and basket plants or simply use them for effective ground cover. They also look good trailing and climbing over conifers, hedges and short walls. Please Note: Occasionally some plants produce pure green foliage, many but not all will develop variegation at a later stage.
