True Annual Plants Die Right Back After Winter. Then We Begin Again In Spring.
Annual Plants with Perennials in Summer Garden.
Perfectly Planned Garden Of Perennials With Annual Flowers Filling the Gaps.
From the late Col Campbell (Gardening Australia) about annual plants: “Botanically speaking, annuals are plants that germinate, flower and die in one year. Of course, that puts most vegetables in the same category, but when we refer to annuals, itโs usually about flowering ornamental varieties โ the ones we use to drag our gardens out of the winter doldrums and remind us that spring is really here”.
True annual plants die right back after their flowering cycle finishes and they have served their purpose ie. they have produced seeds for the next generation, and are unable to live beneath the ground until the next spring – unlike the bulbs. Some examples of Annuals are Pansies, Asters, Delphiniums, Poppies, Snapdragons and Carnations. Some of these annuals can be planted earlier than I ever thought possible. See Hardy Annuals and more about Annuals to Plant in Spring on the Names of Spring Flowers page.
Note: in the centre of the above photo, you can see the beautifully integrated silver-grey of the Dusty Miller plant which is actually a member of the Daisy family. It is used in garden design to show off annuals and perennials in some very beautiful gardens.

If you love Petunias and it’s too cold to grow them, then the amazing new hybrid is for you. It’s called ‘Below Zero’ and has finally arrived after ten years of experiments. If you are looking for Winter Flowering Plants and those for Australia, they are now on their own page. Winter Blooming Plants.
Annuals Underground.
Bulbs come in various forms (true bulbs, corms, rhizomes, tubers and tuberous roots) and begin to grow by themselves after winter because their underground storage systems contain all the food they need for the winter. They are some of the showiest plants of all in spring and summer and even autumn. While bulbs are really perennials because they stay underground for the winter, they are always our ‘annual’ delight which we look forward to every year. Read about bulbs and other clever ways of getting through the Winter.

Biennial Plants.
Biennials have another type of cycle. They complete their whole life cycle in two years. The first year is devoted to growing the stems, roots and leaves, and then the flowers and seeds appear and develop in the second year. That’s amazing. Examples of biennials are: Hollyhocks, Foxgloves, Forget-Me-Nots, Campanulas, Dianthus, some Poppies and Salvias (and many vegetables).
If you plant them at just the right time you can have some annuals flowering in each season, each taking their turn. So many types of flowers overlap with definitions depending on where you get your information, so unless you have to be ‘specific’ for study purposes, it’s fine to call a biennial an annual and vice versa.
Hollyhocks, for instance, are often called annuals and perennials but most are really biennials. Delphiniums are a type of Ranunculus which may grow as an Annual Plant, a biennial or a Perennial. The Chinese Delphinium (Delphinium Grandiflorum) is a biennial.
Herbaceous Plants.
Nasturtium – Tropaeolum
Nasturtiums. Cheerful and delicious Herbaceous Plants.
Herbaceous Plants are often confused with true annuals. Herbaceous plants, as opposed to woody plants, have soft stems and leaves and die down to ground level – but no further – during the colder months.
Annual Herbaceous Plants are those which include all the true annual plants which we have to plant again each year from seed. They die completely each year after flowering and must be regrown from seed once more. These are the ones which gives us so much joy in the winter – as we pore over the seed catalogues once more. Love it! Some of these are the Aster, Zinnia, Calendula, California Poppy, Swan River Daisy or Brachyscome (an Australian Native) and the Larkspur (Delphinium), although this also has perennial forms.
