About this plant
An attractive easy going daisy that has golden yellow flowers with long plump petals, just separated, which sit round a raised boss in a darker shade of gold. The flowers are on long stems that support good sized dark green rather conical leaves. These leaves arch up at the sides and have serrated toothy edges and a smooth surface. This plant flowers freely and makes a cheery contribution to the garden. There are a number of cultivars, better known than the species. This reaches around 1m (3 ft) high with a 60cm (2 ft) spread.

Spring
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.
Summer
Summer - early · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come 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.
