Full details
The Carbeth Plants Iris White Excelsior Bulbs are an ideal choice for gardeners seeking reliable, low-maintenance perennial color that returns year after year. These robust bulbs produce elegant, creamy off-white flowers with striking golden-yellow centers, reaching heights of 60 to 65 cm. While they are exceptionally hardy and attractive to pollinators, they require well-draining soil to prevent bulb rot, making them unsuitable for heavy, waterlogged ground without proper amendment.

FAQs
When is the best time to plant Iris White Excelsior?

Are these suitable for containers?
Yes, they grow perfectly in containers provided the pot has adequate drainage holes.
Do they attract bees?
Yes, they are highly favored by pollinators, including bees and butterflies.
How do I store bulbs if I can't plant them right away?
Keep them in a cool, dry, well-ventilated, and frost-free area away from rodents.
Will they come back every year?

Troubleshooting
Bulbs failing to sprout
Ensure the soil is well-draining; bulbs planted in waterlogged soil may rot before they can grow.
Rodent damage during storage
Store bulbs in a secure, sealed container or a pest-proof room until you are ready to plant.
Poor flowering
Check that the planting location receives adequate sunlight, as they prefer full sun or partial shade to perform optimally.

Setup, Compatibility & Care
For the best results, plant the bulbs during autumn or winter in fertile, well-draining soil. Ensure they are spaced approximately 10 cm apart. If you cannot plant the bulbs immediately upon arrival, store them in a cool, dry, well-ventilated space such as a shed or garage. It is crucial to keep the storage area frost-free and protected from rodents. Once established, these bulbs are remarkably self-sufficient and require very little intervention beyond standard garden weeding and occasional watering during extended dry spells in spring.
