- USDA hardiness zones:
Split-corona daffodil (Division XI). By definition, a split-corona daffodil features a cup (corona) that is split for more that 1/2 of its length. Flowers are usually solitary. Split-corona daffodils are sometimes further divided into two classes: collar types (Division XIA) and butterfly types (Division XIB). ëTricollet is a collar type that produces flowers atop stems that rise 14-16î tall in midseason (March-April in St. Louis). Each flower features white petals (perianth segments) and an orange crown (corona) split into three sections. Narrow, linear to strap-shaped, green leaves in erect to sprawling clumps. Excellent fresh cut flower.
- Full sun to part shade
Easily grown in average, medium, well-drained soil in full sun to part shade. Best in organically rich, sandy to loams that drain well. Plant bulbs 4-6\ deep and 3-6î apart in fall. After the flowers have bloomed, the top portion of each flower stem may be removed, as practicable, to prevent seed formation, but foliage should not be cut back until it begins to yellow. Flowers usually face the sun, so bulbs should be grown with any shade areas at the rear of the planting. Bulbs can be left undisturbed for a number of years."
