I've never thought of Narcissus as being all that fragrant. Earlier
in my horticulture career I am sure I must have stuck my nose in a
few Daffodils and I know in my part-time high school job as a
florist deliveryman they didn't seem to have a fragrance at all.

So imagine my surprise when my questing nose for the most wonderful
fragrance late one spring brought me to a small flowered Narcissus
with grasslike foliage - Narcissus jonquilla, or one of its hybrids.
I've added to the 'must have's' of my garden and have enjoyed this
fragrant delight ever since.
