Posted by Dobies Staff on 07 November 2014 09:30 am

Hermodactylus tuberosus also known as ‘Widow Iris’ and ‘Snakes Head Iris’ and is hardy to -15°C (5°F). Grow the plants in full sun where they are sheltered from strong winds. The plants will grow in most well-drained soils, tolerating both poor and chalk soils. They will reach a height of approximately 20cm (8") in height.

Plant the tubers 10cm (4") deep and 10cm (4") apart. The flowers can appear as early as March in milder parts of the country and in April in cooler areas The flowers have a delicate scent which is strongest in sunshine or a warm room, making them ideal for cut flower displays. The plants may take at least a year to establish before they start to flower. The foliage dies down in summer and dry conditions are necessary at this time. Large clumps can be divided in late summer.
