Plants super poorly packaged, not protected at all. After receiving them, there were broken branches/pots. The customer service response did not satisfy me at all. In order to return them, I have to pay the return fee. I find this unfair. In short, do not order multiple plants at the same time. Otherwise, you will have the same problem as me. We'll see how they recover in a few months.

Description

Kerria japonica 'Pleniflora' or Japanese Kerria is a flowering shrub. From April to May, numerous fairly large pom-pom shaped flowers, 5 to 6 cm (2 to 2.4 in) in diameter appear. These flowers are solitary, double and orange-yellow in colour. Kerria Japonica has a bushy and erect habit with arched stems.

It is a beautiful decorative bush for its light foliage and especially its spring flowers. Japanese Kerria has deciduous, ovate and finely dentate foliage. These bright green leaves measure 6 to 10 cm (2.4 to 3.9 in) long and are pointed at the tips.

This shrub, originating from China and Japan, is particularly floriferous and hardy. Kerria reaches a height of 2 m (6 ft 7 in) with a width of 2m 50cm . It is used in flower beds as well as informal hedges or as a specimen. It enhances patios and also forms a beautiful trellis along medium height walls.

Planting and care

Kerria japonica 'Pleniflora' can be planted from November to February in frost-free conditions, for a flowering period from April to May. Place it in full sun or semi-shade in a rich and well-drained soil. Prepare a hole 60 cm (23.6 in) in width and depth for planting. Then backfill and lightly compact the soil. Water lightly. Kerria japonica has an easy-going nature. It is important to thin out the branches after flowering to avoid the plant becoming too bushy.  Cut back after flowering and remove the old wood to promote flowering for the following year so that the shrub does not just flower at the ends of the branches but all over.
