Jonquilla daffodil (Division VII). By definition, a jonquilla daffodil features 1-5 usually fragrant flowers per stem, each with spreading perianth segments (petals) and a small corona (cup). Narrow, reed-like, dark green leaves appear in upright clumps. ëIntrigue rises 10-12î tall in spring, usually producing up to three flowers per stem. Each flower features broadly ovate, greenish-yellow petals and a shallow, funnel-shaped, yellow cup that ages to white. Flowers are fragrant. Blooms in late mid-season (April in St. Louis). W. G. Pannill, 1970.

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Good soil drainage is essential. Best in organically rich loams. Soils should be kept uniformly moist during the growing season. Plant bulbs in early to mid fall. Planting depth depends upon bulb size. In St. Louis, each bulb should be planted 2 to 3 times as deep as the bulb, with at least 3î of soil over the top. Space bulbs from 4-10î apart (larger bulbs are planted further apart than smaller ones). Larger spacing may look sparse in early years, but the spaces will fill in over time and division will be needed less. In general, most bulbs will be planted 3-6\ deep and 4-8î apart. After the flowers have bloomed in spring, 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. If bloom quality and quantity decline over time, clumps may be divided by digging just after the foliage dies back."
