According to a correspondent of _Notes and Queries_, the practice may be traced to the Saracens, by whom the orange-blossom was regarded as a symbol of a prosperous marriage--a circumstance which is partly to be accounted for by the fact that in the East the orange-tree bears ripe fruit and blossom at the same time.
Then there is the bridal bouquet, which is a very different thing from what it was in years gone by.

Instead of being composed of the scarcest and most costly flowers arranged in the most elaborate manner, it was a homely nosegay of mere country flowers--some of the favourite ones, says Herrick, being pansy, rose, lady-smock, prick-madam, gentle-heart, and maiden-blush.

A spray of gorse was generally inserted, in allusion, no doubt, to the time-honoured proverb, "When the furze is out of bloom, kissing is out of fashion." In spring-time again, violets and primroses were much in demand, probably from being in abundance at the season; although they have generally been associated with early death.
Among the many floral customs associated with the wedding ceremony may be mentioned the bridal-strewings, which were very prevalent in past years, a survival of which is still kept up at Knutsford, in Cheshire.
On such an occasion, the flowers used were emblematical, and if the bride happened to be unpopular, she often encountered on her way to the church flowers of a not very complimentary meaning.

The practice was not confined to this country, and we are told how in Holland the threshold of the newly-married couple was strewn with flowers, the laurel being as a rule most conspicuous among the festoons.

Lastly, the use of flowers in paying honours to the dead has been from time immemorial most widespread.
