Abstract


Thirty daffodil (Narcissus) cultivars/hybrids/species from ten divisions were planted in Tavares-Millhopper fine sand in Apopka, Fla., in Dec. 1998. Full sun plots were fertilized once a year with a 6-10-20 (N-P-K) fertilizer and watered using overhead irrigation. Plant emergence and flowering (date of first color, number of flower stalks, flower duration) were monitored for 3 years. Survival and flowering results were variable. Eight cultivars never emerged after planting. Several others emerged and then died. 'Ceylon' only flowered the first year. 'Double Roman' flowered the first 2 years. N. 'Campernelli' and N. x intermedius did not flower until the third year. By the third year, four daffodils emerged as the most vigorous and floriferous—'Erlicheer', 'Grand Primo', N. x intermedius and 'Minor Monarque ('Early Pearl'). Flower spike longevities ranged from less than a week to over 3 weeks.
