General Description

Extra petal rows creates a full, double-form tulip blossom on 'Carlton'. A early-blooming tulip, sometimes referred to "peony-like," the flowers are satiny red-crimson. It was selected by breeder C.P. Alkemade Cz. and introduced in 1950. Perched atop sturdy stems above broadly lance-shaped leaves, the elegant blooms open early in the season, in the early to mid-spring time frame depending on local climate. A rather short-lived bulbous perennial, this tulip is best treated as an annual.

Tulip bulbs are a favorite food of small mammals including voles, and their succulent leaves and buds are favored by deer. Deep planting (at a depth of four to five times the bulbs' width) and underground barriers (such as buried hardware cloth) can discourage bulb predation. Interplanting with daffodils or other pest-resistant bulbs may deter both below-ground and above-ground pest damage.

Despite these problems, tulips are generally easy to grow. They prefer full to partial sun and require average to fertile soil with good drainage. Leave the lower foliage of perennial tulips after they bloom, so they can collect and store energy for next spring’s display. Once the leaves start to yellow, cut plants to the ground. Hardiness is cultivar/species dependent, but most require at least two months of chilly soil conditions across winter in order to bloom in spring.

Tulips are unsurpassed for bringing spring color to containers or sunny gardens. Be sure to consider height and bloom time when designing with them as these vary greatly from cultivar to cultivar. It is also wise to plant extra of 'Carlton' to use as superb long-lasting cut flowers in a vase indoors.
