Herbaceous perennial flowers are those which do not have woody stems, but
are comparatively soft-stemmed, such as Cosmos, Anemones, Chrysanthemums,
Carnations, Hollyhocks, Forget Me Nots and Delphiniums. These are more
sensitive plants which will die back in very cold climates, but will come
back in spring, retaining their roots and parts of their stems underground.
They are often referred to as ‘annuals’ because of this, but the true
annuals die underground as well.

Hence, herbaceous perennials also include all the plants which have
underground storage systems such as the bulbs, tubers, corms and
rhizomes.The flowers on this page are mainly the Herbaceous Perennials.

The main thing to remember when thinking ‘is this an annual or a
perennial?’ is that unless you want to nitpick, annuals and perennials can
overlap. As the late Col Campbell from Gardening Australia said:

“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, it’s usually about flowering ornamental varieties
– the ones we use to drag our gardens out of the winter doldrums and remind
us that spring is really here”. See this on the Annuals page.

The other different types of Perennials:

Woody Perennials.
Hydrangeas corner
Hydrangea macrophylla.

Woody perennial flowers such as roses, peonies, hibiscus, apple trees and
hydrangeas have tough woody stems and branches which do not die off in the
cold. They may lose their leaves, but they retain the basic above ground
structures.

Deciduous Perennials.
Deep Pink Crepe Myrtle Tree.
The Beautiful Deciduous Deep Pink Crepe (Crape) Myrtle.

Deciduous perennials lose their leaves but retain their above ground parts.
A wonderful example of a Deciduous Perennial is the Crape (Crepe) Myrtle.
This is one of the world’s most loved trees because it has flowers in
spring to summer with lovely green foliage, then it has stunning autumn
colours of reds and yellows. Even its bark is pretty. The flowers are
divine and it was one of my favourite trees that I grew up with. We had a
pink and a purple, but I just loved the pink. It grows from 18 to 25 feet
tall. It only takes a few years to really get going.

Evergreen Perennials.
Alpenroos

Rhododendrons in the Mountains.

Evergreen perennials retain all their foliage during the winter.

However, just when you think you’ve got it all covered, there’s another way
of classifying our garden plants The Monocarps, Polycarps and even the
Paucicarps. Monocarps only flower once before they die, but they may live
for many years before they do this. Polycarps flower time after time and
Paucicarps flower only up to five times before they die. Most of us don’t
need to bother with this type of plant classification (unless you’ve got an
Agave – a Monocarp), but it shows that for Botanists, the sky’s the limit
in classifying plants. The following article goes into these types of
plants in detail: Life Spans of Plants. Perennials however, are definitely
Polycarps.
