About this plant
This tall slender plant has long slim leaves, curved upwards and close packed pale-yellow flowers. The flower stem turns to follow the sun. It is found in waste places, sometimes by the road, enjoying stony, sandy, places in sunny spots. In the past it was used to make a yellow dye. It reaches around 1.2m (4ft) height with 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.
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
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.
Planting & general
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
