  • Plant lovers often look at lists of plants or seeds for sale in the winter to plan their gardens for the coming year.
  • 2
  • Those lists usually have two names for each plant: a common name and a botanical, or scientific name.
  • 3
  • The botanical name is not in English, which makes a lot of people unsure about what it means or how to say it.
  • 4
  • The language is Latin. Its purpose is to help growers be sure that the plant they bring home is the one they wanted to buy.
  • 5
  • The problem with common names is that they are nicknames, or informal names, for plants.
  • 6
  • Many plants can share a common name.
  • 7
  • One plant can also have many common names. You can see how this can cause misunderstandings.
  • 8
  • For example, you may have heard the name "geranium."
  • 9
  • The common name for the true Geranium is perennial cranesbill.
  • 10
  • The container plant people call the geranium is actually a Pelargonium.
  • 11
  • The Latin system of naming goes back to the 1700s and Swedish botanist, zoologist and physician Carl Linnaeus.
  • 12
  • His books Systema Naturae and Fundamenta Botanica created rules for classifying and naming plants in botanical Latin.
  • 13
  • For this reason, gardeners should try to become familiar with it.
  • 14
  • Linnaeus spent his life giving every plant and animal that he knew a two-part, or binomial, name.
  • 15
  • The two parts are: genus and species.
  • 16
  • These names are often based on the appearance of parts of the plant or animal.
  • 17
  • Linnaeus' International Code of Botanical Nomenclature sets rules for how plants should be named. They include:
  • 18
  • A plant name must start with a capitalized genus,
  • 19
  • The second part of the name is the species, written in lower-case, usual letter.
  • 20
  • Next, the name includes either a variety (if the plant is found in nature), cultivar (if the plant is created by a breeder) or hybrid name (if it is a cross between two plants, an "x" is used).
  • 21
  • The International Botanical Congress has gathered every six years to examine and decide on new naming questions.
  • 22
  • The questions come up because of new genetic research and scientific findings.
  • 23
  • After all, Linnaeus did not have modern microscopes or DNA testing laboratories to decide which plants are related.
  • 24
  • For example, bleeding hearts, once officially called Dicentra spectabilis, were moved into the newly created Lamprocapnos genus several years ago.
  • 25
  • Their name is now Lamprocapnos spectabilis.
  • 26
  • The snapdragon, a popular garden flower, was once in the Antirrhinum genus.
  • 27
  • The Congress moved it into the plantain family, Plantaginaceae.
  • 28
  • Since no group controls the use of common names, the same plant may have several.
  • 29
  • Take Rudbeckia hirta. Some call it a black-eyed Susan, others say it is a yellow-oxeye daisy and others know it as the gloriosa daisy.
  • 30
  • Ask a garden center employee for a snowball bush, and you might walk out with a Hydrangea arborescens or a Viburnum plicatum.
  • 31
  • There is a big difference. The first one has large round flower heads that bloom in the summer.
  • 32
  • The second one has groups of smaller flowers and blooms in the spring.
  • 33
  • But both are beautiful.
  • 34
  • How can you learn the botanical name for a plant before you buy it?
  • 35
  • Search for the common name in the Royal Horticultural Society's free online Garden Plant Finder and get a list of the botanical names.
  • 36
  • You can also search for a botanical name and learn the common names.
