Iris Hookeri Perennial Flower Seeds

Rather resembling a dwarf Iris setosa, this lovely iris has large, reflexed, blue-purple flowers, white-blotched at the centre, and all attractively pencilled in deeper purple, with small standards.

It does best with ample moisture, but must have adequate sun to flower well.

These plants are native to the coastal states of north-east USA and Canada, where they grow in damp places.

KEY FACTS

SOWING ADVICE

For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
