Tulipa tarda
Like many species tulips, Tulipa tarda offers two-tone flowers. Outer petals feature tones of brownish-purple, while blossom centers display yellow petals with white tips. Tulipa tarda was introduced in 1933 and grows 2 to 4 inches tall. Many species tulips, including T. tarda, naturalize readily to create larger colonies via offsets or baby bulbs that form alongside mature bulbs. To enhance this process, remove spent blooms and don’t permit plants to set seed.
