‘On Mulberry Street’ Siberian Iris (Iris sibirica). The 'On Mulberry Street' Siberian Iris is a graceful and durable variety, offering superb purple blooms with yellow and creamy white accents. Its delicate petals are adorned with intricate veins, bringing unique charm to flowerbeds and borders. Its strap-like foliage remains attractive all season, adding a touch of structured greenery even after flowering. Place this selection in a spot you observe often, with enough space around it to distinguish the flowers. Planting it near a pathway allows you to appreciate the plant's details as it develops. Compare the textures of neighboring foliage to create an arrangement that remains clear as the plants grow.
Install this Siberian iris in full sun or bright partial shade, in fertile soil that retains moisture. Prepare a hole wide enough to spread the roots without bending them, then place the plant at its planting depth. Carefully backfill and water to ensure contact between the soil and the roots. Unlike bearded irises, this group prefers cool soils and does not require an exposed rhizome in the sun. Leave space around the clump: the foliage gradually forms a significant presence in the bed and should remain accessible for routine care.
Monitor watering during establishment and dry periods to maintain consistent moisture without standing water. After flowering, cut back spent flower stalks and keep healthy leaves, which continue to structure the bed. Remove dried foliage when its cycle is complete. An application of well-decomposed compost around the clump can maintain soil fertility, without excessively covering its center. When the plant becomes too crowded or flowers less, divide it and replant the divisions in prepared soil. Keep young divisions watered until they are established and avoid immediately competing them with large neighboring plants.

Growing method
Plant this Siberian iris in full sun or bright partial shade, in fertile soil that retains moisture. Prepare a hole wide enough to spread out the roots without bending them, then place the plant at its growing depth. Carefully backfill and water to ensure good contact between the soil and the roots.

Soil and care
The right care,at the right time.
Watering
Keep the soil consistently moist during growth, without waterlogging it. Check moisture levels beneath the surface and water at the base before the root zone dries out completely. Pay particular attention to new plantings and during hot or windy periods. An organic mulch helps limit evaporation, but don't pile it up against the base of the stems. After a rain, wait until the soil needs water before watering again. For potted plants, always allow excess water to drain away.
Soil type
For this Siberian iris, opt for a fresh to moist soil, rich in organic matter and loose enough for the roots. Check the drainage after rain: water must be able to leave the root zone. Work the soil when it is crumbly to avoid compacting it. Adapt soil amendments to its actual texture. In containers, use appropriate potting soil and a pot with drainage holes. Keep these openings clear and prevent any water accumulation in the saucer.
Fertilization
Before adding fertilizer, consider the richness of your soil and any previous applications. A soil analysis can help you choose the most beneficial amendments. If you use a fertilizing product, follow the dosage, frequency, and application method indicated on its packaging. Avoid concentrated applications directly against the roots. Do not overdo it with multiple products: an excessive amount of fertilizer does not guarantee better growth or more abundant flowering.

An application of well-rotted compost around the clump can maintain soil fertility, without excessively covering its center. When the plant becomes too dense or flowers less, divide it and replant the divisions in prepared soil. Keep young divisions watered until they establish and avoid immediately competing them with large neighboring plants. Over the seasons, observe new shoots, soil moisture, and stem condition. A durable label helps locate the planting during its dormancy. Clean tools after cutting diseased parts and remove debris that degrades around the base.
Container growing
A garden,within reach.
Container gardening requires anticipating the necessary volume for the roots and the final height of the plant. Choose a stable pot with drainage holes and a suitable planting medium. Leave enough space to respect the recommended depth and spacing, rather than cramming plants together to fill the pot immediately. Place the container in the indicated exposure and regularly check for moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting in open ground. Therefore, plan for a wintering location compatible with the plant's needs and your region's climate from the outset.

How to successfully plant Iris sibirica 'On Mulberry Street'?
Install this Siberian iris in full sun or bright partial shade, in fertile soil that retains moisture. Prepare a hole wide enough to spread the roots without bending them, then place the plant at its planting depth. Backfill carefully and water to ensure contact between the soil and the roots. Unlike bearded irises, this group prefers cooler soils and does not require an exposed rhizome in the sun. Leave space around the clump: the foliage gradually forms a significant presence in the bed and must remain accessible for routine care.
What light should I provide for Siberian Iris 'On Mulberry Street'?
The recommended exposure is from sun to partial shade. Observe the light at the chosen location in the morning and afternoon, as the shade from trees or buildings changes throughout the day. Also, consider nearby plants: their foliage can obscure a young plant as it develops. For potted plants, place the pot where you can move it if conditions become too hot or too shady. Suitable exposure must go hand in hand with appropriate soil and watering. If you are moving a plant started indoors outdoors, gradually acclimate it to garden conditions to avoid too abrupt a transition for the young leaves.
How to adjust watering?
Water according to the actual soil moisture, taking into account rain, heat, and wind. Check below the surface before deciding on a new application: soil that is dry on the surface may still be moist at the root level. Direct water to the base and allow it to penetrate, without keeping the plant in saturated soil. Containers generally require more frequent checks because they dry out faster. Make sure their drainage holes remain clear and empty any saucers that collect water. Also adapt care to the plant's cycle: active growth and a resting period do not require the same inputs.
What should I plan for container gardening?
Container gardening requires you to plan for the necessary volume for the roots and the plant's final height. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than crowding the plants to fill the pot immediately. Place the container in the indicated exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, from the outset, plan a wintering location compatible with the needs of the plant and the climate of your region.
What aftercare is needed after the growing season?
Monitor watering during installation and dry spells to maintain consistent moisture without stagnant water. After flowering, cut back spent flower stalks and keep healthy leaves, which continue to provide structure to the bed. Remove dried foliage when its cycle is complete. Adding well-decomposed compost around the clump can maintain soil fertility, without excessively covering its center. When the plant becomes too crowded or flowers less, divide it and replant the divisions in prepared soil. Keep young divisions watered until they are established and avoid immediately competing them with large neighboring plants.
