How to grow:
Siberian Irises need to be planted with the tops of their rhizomes about 5 cm deep. Leave about 50cm between them, as they will form clumps.
They are not fussy about the type of soil, but do need about half a day's sun to flower well.
They like moist positions, but will also do well in drier places - possibly growing a little shorter. But do water well until they are established. You can divide them in spring or autumn after about three or four years.

They flower from mid-May to mid-June. E is early in that period, M is mid and L is late.
