About this plant
A plant of modest charm with starry five-petalled yellow flowers that flower for a long period from spring to midsummer. The flowers splash attractively across the large pointed green leaves that are held in pairs, opposite each other. This spreads gently by means of runners. It is found growing naturally at the edges of woods across a wide range in the USA from Ohio to Florida. It makes good groundcover and is best left to fend for itself except in times of drought. It is happy in a lightly shaded position which is a useful attribute.

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 - late · Planting
Divide when too large
When the plant is too large clumps may be divided into two or more pieces. Rhizomes can be cut, whilst small bulbs or offsets are detached. The new plants can be grown in a container or planted in the ground.
