About this plant
This is a candelabra primrose which means the flowers are held in tiers on the vertical flowering stalk. The developing seed-pods of the spent tiers may be seen below the current whorl of flowers which sit atop the stalk. The leaves make lush green rosettes. The flowers are white, rose or purple and appear in May and June and, on their long dark stalks, appear to float above the dense foliage. It really needs to grown in a colony for effect and looks good in moist woodland conditions. It will interbreed and resultant seedlings may be of variable quality. The plant likes a cool part shaded site.

Autumn · Planting
Remove offsets to create new plants
Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.
Spring
Spring - late · Outdoors
Feed with sequestrol
If plants are acid loving and grown in soil with little acidity, or in a container, or are watered with limey tap water an annual feed with sequestrol (iron chelate) is highly beneficial. Follow guidelines on the packet. Will also 'blue-up' hydrangeas.
For hydrangeas that have good blue flowers in acid soil, this product can be used with alkaline soil to turn the flowers blue. This is most effective when the soil is neutral or just slightkly alkaline.
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.
Planting & general
Outdoors
Water with rain water
This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.
Compost · Planting
Multi-purpose compost
Use a good quality peat-free multi-purpose compost when growing in pots and containers.
