Simply magnificent, flower in late summer in the Shetland Islands - on a south-facing slope, facing the sea in ordinary, acidic soi. It is winter-growing and does not lend itself readily to vegetative propagation once the new shoots are above ground. Lift and tease apart in autumn, as soon as foliage has died down.

Gladiolus cardinalis - a rare Sth African native - has vibrant tomato red flowers splashed with cream, which blooms in late Spring, is valuable as a cut flower, and is easily grown.
There are over 200 species belonging to this interesting genus of cormous plants with very few in cultivation.
I brought corms from my last garden, and this healthy plant is set to give splendid colour and much enjoyment.
