Narcissus bulbs are poisonous. There are various types of narcissuses. All of them send up shoots with sword-shaped leaves. Many botanists consider daffodils to be long-trumpet narcissuses. Jonquils are short-trumpet narcissuses.
Gardeners usually plant narcissus bulbs in the fall.
The flowers are perennial. Another short-trumpet species is the poet's narcissus. It produces a single, wide-open blossom on each stalk. Generally, the blossom has white petals surrounding a short, yellowish cup with a crinkled red edge. The paperwhite narcissus is a short-trumpet species that can be grown indoors in winter from bulbs placed on pebbles.
