A flowerpot, flower pot, or plant pot is a container in which flowers and other plants are cultivated and displayed. Historically, and still to a significant extent today, they are made from terracotta. Flowerpots are now often also made from plastic, wood, stone, or sometimes biodegradable material. An example of biodegradable pots are the so-called "Jiffy" pots. There are often holes in the bottom, to allow excess water to flow out, sometimes to a saucer that is placed under the flowerpot. The plant can use this water with its roots, as needed. Recently, some flowerpots have been made with an automatic watering system, using a reservoir.

Flowerpots

Flowerpots have a number of uses, from transporting plants to new locations, starting seeds, patio and indoor cultivation of plants, and the growing of tender plants in colder regions indoors. Through the centuries, the use of flowerpots has influenced the horticultural use of plants, and the Egyptians were among the first to use pots to move plants from one location to another. The Romans brought potted plants inside during cold weather. In the 18th century, pots were used to ship breadfruit seedlings from Tahiti to the West Indies. Also Orchids, African violets and Pelargonium geraniums were shipped in pots from other parts of the world, including Africa, to North America and Europe.

In the 18th century, Josiah Wedgwood's flowerpots were as popular as his famous dinner-ware, they were often highly decorative and used as table centrepieces.

In Athens, earthenware flowerpots were thrown into the sea during the festival of the Gardens of Adonis. Theophrastus, c. 371 – c. 287 BC, mentions that a plant called southern-wood was raised and propagated in pots because it was difficult to grow.

The top of the flowerpot underneath the rim is commonly known as the shoulder or collar and can aid handling.

Traditional classification

Flower pots were traditionally made from terracotta. They were made and sold by the cast, which is the number of pots produced from a given quantity of clay. The traditional sizes were as follows, although others existed:

Name	No. to cast	Top diameter (inches)	Depth (inches)
Ones	1	20	18
Twos	2	18	14
Fours	4	15	13
Sixes	6	13	12
Eights	8	12	11
Twelves	12	11.5	10
Sixteens	16	9.5	9
Twenty-fours	24	8.5	8
Thirty-twos	32	6	6
Forty-eights	48	4.5	5
Sixties	60	3	3.5
Seventy-twos or thimbles	72	2.5
Thumbs	80	2.5	2.5
Nineties or thumbs	90	1

A taller and thinner shape of pot, suitable for deep-rooting plants, was known as a long tom, a term still used. The traditional size for a long tom used for auriculas was 3 in diameter by 3.75 to 4 in depth.

Nursery pots

In the nursery business, plants are generally grown in round or square plastic pots.

United States

The sizes of plastic pots have been assigned an ANSI standard by the American Nursery and Landscape Association. Pots designated #1–#100 nominally have the volume of that many gallons, but in fact a #1 pot has a capacity of 0.625 gallons (a "trade gallon"). There is also a Small Plant series: SP1, 6.5–8.0 in³; SP2, 13.0–15.0 in³; SP3, 20.0–30.0 in³; SP4, 51–63 in³; SP5, 93–136 in³. An SP4 pot is commonly called a "4-inch" or "quart" container.

Europe

Plastic pots come in a number of standard sizes, with a code indicating the approximate dimensions of the diameter at the top.

Code	Diameter	Height	Volume	Approx. Imperial equivalent
6F	6 cm	6 cm		2.25"
8F	8 cm	7.5 cm		3"
9F	9 cm	9 cm		3.5"
10F	10 cm	9.5 cm	0.5 l	4"
13F/14A	13 cm	12 cm	0.9 l	5.5"
