Lathyrus Odoratus
Sweet Pea

This vividly colored, climbing flower is a native
of Italy.  Its scientific name is Lathyrus.  Since
its colors are strong oranges, lilacs and purples and
its flowers are extremely fragrant, Italian royalty
used this as part of the altar setting at weddings. 
One common variety identifies this wedding
connection through the name "Royal Family."

Once the flowers were cultivated professionally,
breeders eliminated much of their scent.  Now smaller Sweet Peas have absolutely no fragrance.  Most varieties of Sweet Peas are readily available in the spring.
