The Solomon Seals, a family of hardy perennials that will grow almost anywhere. Their preference is for heavier, moisture retentive soils in some shade. Sunnier situations will result in shorter growth, while some will get impressively tall in the shade. They are affected by the Gooseberry Saw Fly caterpillar – though not all to the same extent, if you cannot abide the shredded look they leave I suggest that you try P. odoratum which seems unaffected as are others noted below. Do try to order early, because in March as they start to grow again they get very brittle.
