The Much Requested Garden Glossary


Over the years as I have written this blog, I have had a number of people write a comment on an article that pretty much follows the same summation: “Hi, please don’t put this up on your blog, but what does ______ mean. I have never heard of that one.”  Some of the words are scientific names that are in Latin, while others are maybe a little more ‘high end’ gardening terms that a beginner may not know.

Either way, I thought it would be a great time to compile a number of the gardening terms I have been asked to define into one nice little article.  If asked again, I can get a link click out of it. ;o)

 

Acidic Soil     

A soil that has a pH below 7, typical of clay soils. Azaleas, camellias, dogwoods and roses like acidic soils.

Alkaline Soil     

A soil that has a pH of 7 or higher.

Annual Plant     

A plant living one year or less, usually planted in the spring after the last frost. During this time, the plant grows, blooms, produces seeds, and dies.

Balled & Burlapped     

The roots of the plant have soil attached and are held in place with burlap or some other material.

Bare Root     

The roots of the plant are bare, with no soil.

Biennial     

Of two seasons duration, from germination to maturity and death, usually developing vegetative growth the first year and flowering, fruiting, and dying the second year.  Biennials need exposure to winter temperatures to trigger flowering or fruit production the second year.

Bulb     

A resting stage of a plant that is usually formed underground and consists of a short stem base bearing one or more buds enclosed in fleshy leaves and buds (tulip, daffodil, etc).

Corm     

A rounded, thick modified underground stem base bearing membranous or scaly leaves and buds (gladiolus, crocus, etc).

Crown     

The base of the plant, where the stem and root meet.

Cultivar     

A cultivated variety or strain that originated and has persisted under human cultivation.

Deadheading     

Removing the dead blossoms.  If a plant is termed “self cleaning,” the blossoms fall off on their own.  Deadheading usually extends the blooming season.

Deciduous     

A plant that loses its leaves seasonally, usually in the fall.

Determinate     

The growth of a plant stops at a certain height (usually in reference to tomatoes).

Dormancy     

A period in the life cycle of a plant where it is “asleep” and not actively growing.  Dormancy is brought about by cool temperatures and shorter day length.

Evergreen     

A plant that stays green year-round.

Floriferous     

Bearing flowers/blooming freely.

Germination     

The sprouting of a seed and the commencement of growth.  Also used to describe the starting of plants from seeds.

Grafted Plant     

The top (desirable) part of the plant is grafted onto rootstock, usually of a hardier or less rare plant.

Heirloom Seed     

Mostly open-pollinated seed that have been planted and passed down for generations. Most lack disease resistance.

Herbaceous     

A plant that dies back to the ground in winter and returns again in the spring.

Herbicide     

A chemical used to destroy undesirable plants and vegetation.

Hybrid Seed     

The result of cross-pollination of parents that differ in size, color, taste, or other traits.  Seeds from hybrid plants cannot be saved and used again, as they will revert back to one of the parents.

Indeterminate     

The plant continues growing until pinched or killed by frost (opposite of determinate). These plants usually require staking.

Organic Seed     

A seed that has been grown and harvested without being exposed to any inorganic chemicals, fertilizers, hormones, etc.Pelleted Seed     

Small seed, such as petunias or pentas, that have been coated with an inert material such as clay to make them easier to handle.
Perennial     

A plant that lives for three or more seasons. Perennials may not bloom the first season planted, especially ones that are shipped bareroot.

Rhizome     

A somewhat elongated, usually horizontal subterranean plant stem that is often thickened by deposits of reserved food material that produces shoots above and below the roots (bearded iris).

Rootstock     

Root system of a more common or hardy variety that is used to graft a more desirable variety onto, usually roses and/or standard forms.

Self-Pollinating     

Plants that do not require pollen from another plant in order to produce fruit.

Semi-Evergreen     

A plant that drops its leaves in cold areas but keeps at least some of them in milder zones (typically zones 7~11).

Standard     

A shrub or herb grown with an erect main stem so that it forms or resembles a tree.

Sucker     

Undesirable growth coming from the rootstock of a grafted plant.

Treated Seed     

Seed that have been treated with an insecticide or fungicide to aid in preventing soil insects or disease from destroying the seed prior to germination.

Tuber     

A short, fleshy, usually underground stem bearing minute scaly leaves, each of which bears a bud in its axil and is potentially able to produce a new plant (iris potato, caladium, tuberose begonia).

 

If there is a term that is missing from this list that you would like to know, leave a comment and I will add it! Thanks for reading!
