With a flower head that resembles that of a cobra Arisaema ringens is a standout plant for a shaded garden.
This is a species that comes in two forms, one with a spadix thats is a very deep purple, the other with a green spadix.
It will grow well in the garden in a woodland situation, it is equally at home in a container.
The foliage lasts well through summer and over time the plant will form an attractive clump.
The flowers are held well down below the foliage so growing this one in a container where the plant can be raised a little can make it more of a feature.
