Appearance:
Scilla peruviana forms a rosette of lance-shaped, dark green leaves.
Its most striking feature is the large, conical raceme of star-shaped, violet-blue flowers. These flowers, approximately 1.5cm wide, create a spectacular display in late spring and early summer.
The bulb itself is substantial, typically 6–8 cm in diameter, and has a white base with brown scales.
Growth Habits:
This perennial reaches an ultimate height and spread of 0.1–0.5 meters.
It takes 2–5 years to reach its mature size.
The plant can be considered more or less evergreen.
Scilla peruviana thrives in well-drained soil. Sandy or gritty soils are ideal, as they prevent waterlogging.
It prefers full sun but can tolerate partial shade.
This plant is well-suited for coastal gardens and rock gardens.
Planting:
Bulbs should be planted in the fall, approximately two to three times their depth.
Spacing of 8 to 10 inches is recommended.
In colder regions, container growing is recommended.
Watering:
Water freely during the growing season, especially before, during, and immediately after flowering.
During the summer dormancy, keep the soil relatively dry.

Additional Considerations
Origin and Misnomer:
Despite its name, Scilla peruviana is native to the western Mediterranean region, not Peru.
The reason for the name is due to early botanical misclassification.
Dormancy:
Scilla peruviana experiences a period of summer dormancy.
During this time, the foliage may wither, and the soil should be kept relatively dry.
Bulb Multiplication:
Over time, the bulbs can multiply and form large clumps.
If flowering decreases, bulbs can be divided in early summer.
Scilla peruviana is a truly remarkable plant, offering a stunning display of vibrant flowers and easy-to-manage care. Its Mediterranean origins and adaptability make it a valuable addition to gardens worldwide.
