The 107 Livery Companies are trade associations based in the City of London, each known as the Worshipful Company of the relevant trade or profession. The Livery Companies originally developed as guilds and were responsible for the regulation of their trades, controlling, for instance, wages and labour conditions.

Members generally fall into two categories: freemen and liverymen. One may become a freeman, or acquire the "Freedom of the Company", upon fulfilling the Company's criteria; traditionally, one may be admitted by "patrimony" if either parent was a liverymen of the company, by "servitude" if one has served as an apprentice in the trade for the requisite number of years, or by purchase. (The Company may also vote to admit individuals as honorary freemen.) Freemen generally advance to becoming liverymen by a vote of the Court of the Company. Historically, only liverymen could take part in the election of the Lord Mayor of London.

The Worshipful Company of Gardeners is one of the Livery Companies of the City of London. An organisation of Gardeners existed in the middle of the fourteenth century; it received a Royal Charter in 1605. The Company no longer exists as a regulatory authority for the sale of produce in London; instead serving as a charitable institution. The Company also performs a ceremonial role; it formally presents bouquets to the Queen and to Princesses upon their wedding, anniversary, or other similar occasion.

The Gardeners' Company ranks sixty-sixth in the order of precedence for Livery Companies. Its motto is In The Sweat Of Thy Brows Shalt Thow Eate Thy Bread.

The current master is William Fraser OBE, the Upper Warden is Sir Gavyn Arthur (a former Lord Mayor of London), and the Renter Warden is Christine Cohen OBE.

The Worshipful Company of Gardeners, first mentioned in City Corporation records in 1345, is a survivor from the medieval craft guilds, which 'exercised control over the practice of their particular crafts and ensured a proper training through the system of apprenticeship.

In 1605, after existing for centuries as a "mystery" or "fellowship" the Guild was incorporated by Royal Charter. The Charter sets out the operations controlled by the Company.... “The trade crafte or misterie of gardening. planting, grafting, setting, sowing, cutting, arboring, rocking, mounting, covering. fencing and removing of plants, herbes, seedes, fruites, trees, stocks, setts, and of contryving the conveyances to the same belonging .... "

Today, the Company ranks number 66 in the order of precedence of Livery Companies in the City of London.
