How to grow Kerria japonica ‘Pleniflora’:

Light Requirements: This shrub thrives in full sun to partial shade. Ideally, it should receive at least six hours of direct sunlight per day to promote healthy growth and abundant flowering. However, it can tolerate partial shade conditions, especially in regions with hot summers.

Soil Preference: Plant Kerria japonica ‘Pleniflora’ in well-drained soil that retains moisture. It prefers slightly acidic to neutral soil with a pH range of 6.0 to 7.0. Ensure that the soil is rich in organic matter, which aids in water retention and nutrient availability for the plant.

Planting: Dig a hole that is slightly wider and deeper than the root ball of the shrub. Place the plant in the hole, making sure the top of the root ball is level with the surrounding soil. Backfill the hole with soil, gently firming it around the roots. Water the plant thoroughly after planting to settle the soil and provide initial hydration.

Size and Growth: Kerria japonica ‘Pleniflora’ can reach a height of up to 4 meters (13 feet) when fully mature. Give it enough space to spread and grow. Regular pruning and maintenance may be required to control its size and shape, particularly if space is limited.

Propagation: One method of propagating Kerria japonica ‘Pleniflora’ is through semi-hardwood cuttings. Take cuttings from healthy, mature branches in late summer or early fall. Remove the leaves from the lower portion of the cutting and dip it in a rooting hormone. Plant the cutting in a well-draining potting mix and keep it consistently moist until roots develop.

Care and Maintenance:

Kerria japonica ‘Pleniflora’ is generally easy to grow and relatively pest and disease resistant. Provide regular watering, particularly during dry spells, to keep the soil evenly moist. Mulching around the base of the plant helps retain moisture and suppress weeds. Prune the shrub after flowering to maintain its shape and remove any dead or damaged wood.

In addition to its primary name, Kerria japonica ‘Pleniflora,’ this variety of shrub is also known by other synonyms, including Kerria japonica ‘Plena’ and Kerria japonica ‘Flore Pleno’. These alternative names refer to the same plant, highlighting its double-flowered characteristic. Regardless of the name used, this shrub is a charming addition to gardens, providing cheerful yellow blooms and lush foliage.
