I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Iris sibirica 'Caesar's Brother' is a robust Siberian iris with deep, violet flowers that bloom from late spring to early summer. The blossoms rise on tall, sturdy stems above a mound of narrow, grass-like foliage, which remains attractive throughout the season. This adaptable perennial thrives in full sun to part shade and prefers moist, well-drained, slightly acidic soil. Ideal for borders, rain gardens, and pond edges.

Planting: Plant rhizomes in spring or fall, 1 to 2 inches deep with the crown just below soil level. Space 12 to 24 inches apart. Water well after planting to settle the soil.
Location: Full sun to partial shade. In hot climates, light afternoon shade helps prevent leaf scorch.
Soil: Moist, well-drained, slightly acidic to neutral soil (pH 5.5–7.0). Enrich with compost or peat moss if needed.
Watering: Keep soil consistently moist during the growing season, especially in spring and early summer. Tolerates brief dry spells once established.
Temperature: Hardy in USDA zones 3–8. Cold-tolerant and thrives in northern climates.
Fertilization: Apply a balanced fertilizer in early spring and again after flowering. Avoid high-nitrogen formulas.
Pruning: Remove spent flower stalks and yellowing foliage. Cut back to the ground in late fall or early spring.
Propagation: Divide clumps every 3 to 4 years in late summer to maintain vigor and prevent overcrowding.
Pest & Disease: Low-maintenance and generally pest-free. Good air circulation helps prevent fungal issues.
