Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 5-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.

Hardiness zones: 2-9

In mild temperate areas, the leaves are evergreen, (surviving the winter). But it is best to tidy up the plant and trim the leaves back before the winter, this reduces wind rockage (and root disturbance), then in spring, new leaves will emerge.

Germination: As with many perennials, these seeds require a period of moist cold to help them grow. This is done by giving them a cold ‘winter’ period (artificial or natural), and then a warming to simulate ‘spring’, and time to grow! Here’s how this can be done:

Iris setosa is suitable to be grown in the front of a border, on the sunny edge of a woodland garden, or in a bog garden The iris prefer to grow in moist or wet soils, though it can adapt to various conditions, including partially dry conditions if there is part .

Alternatively, these seeds can also be planted outdoors in fall, winter, or early spring, while temperatures are still cold (but ground is workable) to germinate naturally in spring. Be sure to mark the area where you planted them. This method is only advisable if you are able to ensure that the soil is consistently moist during the entire germination period.

This lovely plant, bearing delicate blue and white flowers, was originally collected from damp meadows around Korsakov on our Sakhalin (Russia) expedition (RBS0233). It will, however, do perfectly well in dry conditions.

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.
