Tulipa Casa Grande Tulip Bulbs

Royal Horticultural Society Award of Garden Merit

Plant Tulipa Casa Grande bulbs in autumn before the first frost, and early the next spring, they wake up the garden with their extra-large, bold-red blooms. Borne singly atop tall, sturdy stems rising to about 22 inches, these beautiful bowl-shaped blooms sit above attractive mottled and striped, gray-green leaves, creating an extraordinary display. They make excellent cut flowers for unforgettable bouquets and mixed floral arrangements.

A Tulipa greigii cultivar, Casa Grande is a bulbous perennial but is often grown as an annual. In ideal growing conditions, Casa Grande tulips may naturalize and return for several years. Tulips look their best when planted in groups in beds and borders, in masses under deciduous trees in the landscape, or in large sweeping drifts in open woodlands. Tulips mix well with other spring-blooming bulbs and planting several different varieties of tulips will extend the flowering time. Tulips make a great ground cover, which can be especially useful for controlling erosion during spring rains. They also grow well in patio pots and can be forced for indoor blooms in winter. Tulips work beautifully in any style garden, but they're a must-have for cottage, informal, and rock gardens.

The Casa Grande tulip is cold hardy—to Zone 3— and grows easily in sunny locations; but in warmer climates, some light shade may help to keep them cool and extend their bloom time. Tulips prefer average to nutrient-rich, free-draining soil with a neutral to slightly acidic pH. Just be sure when planting to allow adequate space between bulbs and plant them at the proper depth—4 to 8 inches apart and 4 to 8 inches deep. Feed bulbs with a well-balanced fertilizer, like Espoma Organic® Bulb-tone® Bulb and Flower Food, as soon as growth begins in spring to encourage robust flowering in both the current season and the following spring season. Remove spent flowers immediately but allow the leaves to turn yellow and wither before removing. In USDA Zones 8-10, refrigerate the bulbs for no less than eight weeks.
