Frequently Asked Questions

Pond Advice

Blue Lis thrives best in moist, well-drained soils and in full sun to partial shade. They are particularly suitable for the edges of ponds and water features, where the roots can remain moist.

Because the Blue Lis grows naturally in wet environments, it is important to make sure that the soil in which they are planted always remains moist. In drier periods, you may need to water daily, especially if they are not directly in or near water.

It is best to prune back the Blue Lis after flowering, usually in late summer. Remove spent flowers and cut back the dead or excessive foliage to encourage the growth of new flowers next season.

Yes, the Blue Lis is hardy in many climates, although it is a good idea to protect the base of the plant with mulch if you live in an area with very cold winters. This helps to insulate the roots from freezing.

Yes, the Blue Lis can be grown in a pot grown, provided the pot is large enough and provides good drainage. It is important to keep the soil moist and place the pot in an area where the plant can be partially shaded, especially during the hottest hours of the day.

Blue Lis

Known for its striking, deep blue flowers, the Blue Lis is an ornament to any garden, especially those with water features or ponds. Also known as the Japanese iris, this perennial aquatic plant brightens up any garden with its elegance and natural beauty. Because of its love for moist soils, Iris Kaempferi is ideal for the edges of water bodies where it not only beautifies the environment but also contributes to a healthy aquatic ecosystem through its filtering properties.

Growth and Care of Iris Kaempferi

For those who want to enrich their garden with the Blue Lis, it is important to know how best to care for this plant. Iris Kaempferi prefers a spot in full sun to light shade and prefers an acidic to neutral pH balance in the soil. Good permeable but consistently moist soil is essential. Regular watering is crucial, especially in drier times, to keep the soil around the iris moist. Annual fertilization after flowering can help promote health and flowering for the next season.

Pruning and winter hardiness

It is important to properly maintain the Blue Lis through pruning. After the flowering period, which usually occurs from late spring to early summer, spent flowers should be removed to keep the plant tidy and to save energy for the next growing season. Although Iris Kaempferi is fairly hardy, in very cold climates it may be necessary to protect the base of the plants from freezing with mulch.
