About this plant
This delicate poppy grows from a pretty foliage base. It has flat-matt, bluish-green, lobed leaves, the lobes being cut to the central red rib. Each lobe looks rather like an oak leaf with a crinkled surface. There are yellow poppy flowers during late spring or early summer. Once the flowers are over there are silvery seed pods. This plant enjoys a cool, partly or fully shaded woodland site with humus rich soil. It grows to around 45cm (18in) height with a 30cm (12in) spread.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Spring - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
