The amazing ivory white Tulip Spring Green makes quite a show in late spring. Altough not brightly coloured, the gimmick is the pure green flame. This playful pattern can make a garden look totally different without using pink or purple to stand out. The strong Tulip Spring Green tends to come back for years and has been awarded the Award of Garden Merit by the RHS for its strong quality. Introduced in 1969 and has since then produced several other viridiflora varieties.
