This daffodil's trumpet, or cup, is equal to or longer than the petals that surround it. The trumpet narcissus produces only one flower on each stem. However, other types of daffodils may produce more than one flower per stem. Daffodils grow from bulbs, which are planted in the fall. Smaller bulbs can be placed closer together and somewhat less deep.
Most bulb growth occurs after flowering.
Thus, the leaves, which make food for growth, should not be removed for at least 10 weeks after the flowers have faded. Daffodil bulbs are poisonous if eaten. Scientific classification Daffodils are in the amaryllis family, Amaryllidaceae. Trumpet narcissuses are cultivars of the species Narcissus pseudonarcissus. This information is taken from World Book .
