This blue iris is a relatively low but dense iris that thrives well in ordinary garden soil and preferably in full sun.
Iris is one of the most beautiful things you can have in the garden and blooms in June, when you miss the intense colours in the garden. Irises are easily recognisable because their elaborately shaped heads are unlike other summer flowers that bloom early in the year.
Iris seeds can last for many years, which makes germination rates difficult to judge. You may find that an iris seed can survive in the soil for several years before it finds it has the optimal conditions to germinate. So don't give up if you don't get many plants from the start. They may come later.
Irises can either be sown directly on the growing site in August-October or very early spring, or you can pre-germinate them on the windowsill in early spring and later transplant them where you want them. It is important to keep the soil moist until the root has taken hold.
