I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Scilla Peruviana 'Portuguese Squill'

Portuguese Squill

Scilla peruviana, also known as Portuguese Squill, is a bulbous perennial native to the western Mediterranean. It produces large, conical clusters of star-shaped violet-blue flowers, each bloom measuring 1–2 cm across, with up to 100 flowers per spike.

This species thrives in fertile, well-drained soil in full sun or partial shade. It grows 4–10 inches tall and 6–8 inches wide, making it an excellent choice for naturalizing in gardens. Blooming in late spring to early summer, it bridges the gap between late tulips and early perennials.

Growing and Maintenance Tips for Scilla Peruviana 'Portuguese Squill'

Planting: Plant bulbs in fall, 8 inches deep with the pointed end up. Ideal for borders or containers in a sunny, sheltered site.
Spacing: Space 5 inches apart in the ground; closer in pots for a fuller look.
Light: Prefers full sun. Needs abundant light to bloom well—avoid deep shade.
Soil: Well-drained, sandy or loamy soil with a pH of 6.0–7.5. Add grit to improve drainage if needed.
Watering: Water sparingly. Keep soil just moist during active growth, then dry during summer dormancy. Overwatering can cause rot.
Temperature & Protection: Hardy in USDA zones 7–10. In colder zones, grow in containers and move under cover in winter, or mulch deeply to protect from frost.
Fertilization: Feed every 2 weeks with a high-potash fertilizer from bud formation through bloom.
Pruning: Deadhead spent blooms. Allow foliage to die back naturally—sometimes it remains evergreen.
Propagation: Multiplies by offsets. Divide clumps in late summer or early fall if overcrowded.
Pest & Disease: Generally pest-free. Ensure good drainage to prevent bulb rot.
