This blog is inspired by the recent blackout campaign against over priced rugby jerseys, and as a support for the All Blacks.
What is black?
If you ask physicists, they will say that black is not a colour.
When there is no light it is black.
For the rest of us who live in the real world, black is a dark colour.
In the plant world, different parts of a plant can appear black in colour due to the high concentration of different pigments.
For example, a very dark red flower would look black.
Here are a few examples of black plants.
Hollyhocks (Alcea rosea) is an old staple of cottage gardens.
Traditionally they have been red but breeding has resulted in a variety of colours.
Here is a dark red, almost black one.

Sweet peas (Lathyrus odoratus) has also been in cultivation for a long time.
Gardeners have selected very dark red forms that appear almost black.

Corn poppies (Papaver rhoeas) have been bred to produce many colours.
A particularly dark red variety looks almost black.
