Dwarf iris 'Alsterquelle'

Iris pumila 'Alsterquelle' produces large pale blue flowers that bring fresh colour to the garden in early spring. This compact dwarf bearded iris forms dense clumps of narrow grey-green foliage and is especially suited to rock gardens, dry stone walls, and sunny border edges. Its low habit beautifully showcases the elegant flowers, which are also highly attractive to bees.

Care/Water

The Iris pumila 'Alsterquelle' requires regular watering throughout the growing season, especially on hot days or during dry periods. The soil should always be slightly moist but well-drained to avoid waterlogging. Water directly at the roots and avoid wetting the foliage to prevent fungal infections. Consistent moisture supports strong roots and healthy leaf growth.

Maintenance

Regularly remove faded flowers to allow the plant to focus energy on new buds. Trim old or damaged leaves as they die back. Use organic fertilizer in spring to support growth and flowering. Check the plant regularly for pests or diseased leaves.

Location

The Iris pumila 'Alsterquelle' thrives in a sunny location with good air circulation. Partial shade is possible but may reduce flowering. Ensure the soil is well-drained to prevent root rot. An open spot promotes vigorous shoots and healthy foliage.

Tip

A helpful tip is to apply a thin mulch layer around the plant after flowering to retain moisture and nutrients. This keeps the plant vital and ready for the next flowering period. Regular checks make maintenance easier.

Iris pumila 'Alsterquelle' has compact fresh green foliage and flowers that give rock gardens and borders a bright accent. The foliage supports the blooms and keeps the plant healthy and attractive.
