About this plant
This is a pretty, rather distinguished, cow parsley look alike. It has frothy foliage, with delicate ferny leaves, ovate and deeply dissected, spread outwards. It makes a foliage mound that piles itself up, covered in large white flower heads that come in summer. It needs to be given sufficient space so its beauty can be fully appreciated. Give it a sunny or partly shaded somewhat sheltered spot in fertile soil that is well drained but always has moisture in it. This reaches 1.5m (5ft) height and 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.
Spring-Autumn · Outdoors
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.
