Scilla peruviana L. (the proposed name change for this species is Oncostema peruviana) is native to Portugal, Spain, and south of Italy, not Peru! There is a tale about the arrival of the bulbs on the ship named 'Peru' discussed here. It is winter growing and spring blooming with a short dormant period in summer and the reputation for skipping flowering seasons on occasion. The species is widely grown in many gardens with Mediterranean climates.
Photos by David Pilling: photo 3 shows commercial bulbs on a 10 mm grid; photo 4 a seed head and photo 5 seed.
Photo 1 is of a clump with 14 flower stalks, although some not visible, grown from Angelo Porcelli. Photos 2-3 were taken by Rodger Whitlock at an early stage of flowering. Photos 4-5 were taken by Kathleen Sayce.
Here is a picture of a white flowering one taken by Mary Sue Ittner.
Scilla sicula is considered to be a synonym of this species according to some authorities.
This form, known in horticulture as "harrisiana" has pinkish mauve flowers and it's a sterile triploid, it never set seeds and it's likely to be a cross of peruviana x Scilla sicula, although its origin is unknown and the varietal name has no validity. Photo 2 is a pale blue form and photo 3 is a dark purple-violet form, both selected by Angelo Porcelli in a batch of seed grown plants.
