Over the years I have used gardening as a retreat from the rush of everyday life. Gardens offer a year round place of exercise and enjoyment

Gardening Jargon

It can often feel like experienced gardeners have a secret language all of their own. The jargon they use might include plants and flowers with long-sounding Latin names, different terminology for types of plants that handle different growing conditions and climates, etc.—the list sometimes seems endless.

And yet, ultimately, we all want the same ends—to have a varied display of colour and form around our home that keeps pace with ever-changing seasons. For the new gardener, it is certainly worth taking the time to understand a little of the gardening language and terminology used.

The New Gardener

Gardening can be such a huge subject to get to grips with. For new gardeners, their first visit to a garden nursery can be a frustrating one, especially when faced with the huge variety of plants and flowers on display. Often their confusion is only added to when packaging and labels of would-be purchases come with labelling that uses terms such as “Hardy Annuals” or “Biennials." Just what does this mean?

Are You Frustrated By Gardening Terminology?

Perhaps you have just acquired a house with a garden and are thrust into quickly having to maintain its appearance and impact – it can be quite daunting. Or perhaps you have become frustrated when that much-loved plant or flower fails to reappear the following year. Do you worry that may have mistreated the poor thing and that it has died from neglect?

Well worry no more – all plants have a natural life cycle. Some are short lived – shining brightly like a rock-star for only one glorious season while others live a more sedate and long-lived life, sometimes growing and maturing for years if not decades.

Whichever your preferred choice of planting is, it helps to understand the different terminology used to describe the lifespan and weather condition that are associated with your desired plant.

Gardening Terms Related to a Plant’s Lifespan

There are 3 gardening terms used to describe the length of a plants lifespan. These are:

  1. Annual
  2. Biennial
  3. Perennial

What Are Annual Plants?

Annual plants live for one growing season and then die. During the course of one season, the plant completes its entire life cycle of growth, going from seed to flower, producing seeds of its own and then dying.

If you like the idea of mixing it up, and don't mind having to replant fresh and different flowers regularly, then annual plants could be your thing.

When planting annual flowers, the best that you can hope for is that some of their seeds may have fallen nearby and that new flowers spring up from these next year. However, this something of a gamble and the only way to be certain of a renewed flower bed next spring, is to re-plant.

You will often hear of gardeners using a technique called “dead-heading” to remove old flowers, preventing them from going to seed. This encourages fresh flower growth and prevent unwanted seeding of nearby flower beds.

Annual Plants: An Ideal Choice for Gardeners With Limited Available Time

Annual plants are ideal for the new gardener who has limited time to spend looking after his land. They are fast growing, high performing plants that once you have prepared the flowerbed, your involvement with maintaining these plants will be minimal for the remainder of the year.

What Are Biennial Plants?

Biennial plants have a life cycle of two years. In their first year they grow, in their second and last year, they reproduce and die.

This type of plant starts from seed. In their first year they produce roots, stems and leaves. During their second year, they produce flowers or fruit, after which they perish and die.

What Are Perennial Plants?

What matters most to you when selecting plants for your garden? Is it to have plants that will stand the test of time and that will remain in place, growing away, year after year without the need to be constantly re-planted each season? If so, then planting perennial plants may be the ideal choice for you.

Perennials regrow every spring (they have a life-cycle of more than two years).

These plants survive through the winter, either as a plant visible above ground or out of sight as dormant roots below the ground before re-emerging the next year.

Perennials plants tend to be easy to care for plants. Like annual plants they can produce a colourful display, but they also have the added advantage of not needing to be replaced every year. I use perennial planting to ensure that certain parts of my garden are as low maintenance as I can manage.

Lifespan by Plant Type

Type of Plant
Lifespan
Example Plants
Comments
Annual
1 Growing Season (1 year)
Dahlia, Geranium, Poppy, Petunia
Each year you buy seeds or seedlings and plant them. You fertilise and water them throughout the growing season. They flower and produce seed before they die and you pull them out.
Biennial
2 Growing Seasons (2 years)
Delphinium, Forget-me-not, Sweet William.
In their first year they produce roots, stems and leaves. During the second year, they produce flowers or fruit, after which they reseed and die.
Perennial
3 or more Growing Seasons (3 or more years)
Asters, Daffodils, Peonies.
Once these plants are established in the ground, they generally need less feeding and maintenance than annual plants. Their root system spreads more widely than annual plants and they fill out more space in your garden.

How Will I Know What To Look For When Purchasing Seed Packets?

So how do you know which type of plant or flower seed you are looking at when at a garden nursery or shop?

The vast majority of seed packets, indicated this on the reverse side of the packet, usually on the top left or right.

Herbaceous Perennials

These are non-woody plants (woody plants being trees and shrubs). Herbaceous plants have green and soft stems. They tend to grow very fast so that they can produce flowers and seeds in a very short elapsed time. It is usually small herbaceous plants that occupy otherwise barren land first. This is due to the fact that they tend to be small, close to the ground and produce lots of seeds.

Tender or Hardy Plants: What Does It Mean?

As well as needing to know how long your plant will survive for, you will need to know if it can withstand the cold weather during the winter months.

Gardeners differentiate between a plants ability to cope with winter weather or not by naming those plants that can as being HARDY and those plants that cannot, as being TENDER.

A couple of good examples of a “Hardy” plant would be a hedge or tree. These overwinter without much fuss and start re-growing again come spring. Not much for the new gardener to have to do here as they pretty much take care of themselves as they overwinter.

Tender plants on the other-hand – will need you to help them over-winter. A good example of this would be a tree fern. You may need to cover it with a fleece during winter months – or if possible, bring it indoors.

Plant Type
Comment
Herbaceous Annuals
Strictly speaking, all annual plants are herbaceous. They have a short life-span and neither the time or the energy to develop anything but soft, non-woody stems.
Herbaceous Biennials
Plants whose stems die back after the first year, but which re-emerge the following growing season, flower and then die in their second year.
Herbaceous Perennials
Plants which die back each year. However, their roots or other underground parts survive through the winter.

Horticultural Terms Related to Plants Ability to Tolerate Weather Extremes

The terms you may see related to this are:

  • Hardy
  • Half-hardy
  • Tender

So just what do these terms mean?

Hardy plants: are able to cope with outdoor winter temperatures down to minus 15C. In other words, they are able to survive in open ground all year around.

Half-hardy plants: whilst they may survive cold weather, they are unable to survive heavy frosts and must be brought indoors during the winter.

Tender plants: this is something of a catch-all term to describe plants that do not thrive in cold weather. This term can, on occasions, also be used to describe plants that do not thrive in heat.

As you might expect, various gardening terms can be put together or paired to add more detail to the description of plants. For example, “Perennial” and “Hardy” can be paired to describe a plant that regrows every spring AND is able to cope with very cold outside temperatures during the winter months.

This begs the question – Can Annual plants be Hardy? The answer is yes, however, they tend not to have the same definition of hardy as used with perennial plants. Annual Hardy plants tend to be plants that can survive light to moderate frosts during spring and may require additional protection from the cold during period of heavy frosting.

Combining Gardening Terminology

Half-hardy annuals such as Rudbeckia, Dahlia and Petunia die if exposed to the cold, so they can't go into the garden until after the last frost. Sown indoors in spring, they will keep going until killed by the first autumn frost.

Half-hardy biennial plants complete their lifecycle in two years, but like the half hardy annual plants, they need winter protection

What Is Overwintering?

This is the name given to the various methods of protecting your plants from the cold. You can do this by putting them somewhere sheltered from the elements. These methods may include:

  • Covering dormant plants with a thick layer of mulch – effectively insulating the plant.
  • Place plants in a cold frame
  • Place plants indoors – in a shed, windowsill or basement

To Harden Off a Plant

You might also have heard the term to “harden off” a plant. This is used to describe the process of acclimatising young plants that are growing in a protective environment, to enable them to cope with cooler conditions outdoors. This is normally done by leaving plants outside during the day and bringing them undercover at night.
