Narcissus jonquil and Narciuss tazetta are two daffodil cultivars endowed with flowers that have a heady perfume. These members of the Amaryllis lily family are probably hybrids of Japanese daffodils. Each flower in the pictures below is about 1.8cm in diameter, but their heady fragrance can be felt metres away.
