About this plant
This has clusters of quite small flowers held on plum brown hairy stems. The flowers are coloured blue with neat golden hearts. The leaves are elegant. They are dark green and with a shiny surface. This can well be in flower for the entire year. General care: These need a bright position out of direct sunlight. They only flower well if conditions are bright enough. Give them a good fertiliser every fortnight throughout summer (specialist fertilisers are available). Water regularly but moderately, they do not like to be waterlogged. Repot annually in good quality houseplant compost.

Spring
Spring-Autumn · Indoors
Feed with high potash feed twice
Use a houseplant fertiliser that is high in potassium several times while the plant is in flower.
Where fertiliser values are listed on a packet they are in order - nitrogen, phosphate, potassium with percentage values of each. For high potassium choose a fertiliser where potash is higher.
Spring-Autumn · Indoors
Water regularly during growth
Water regularly while in growth.
Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.
Summer
Summer · Indoors
Feed with liquid phosphate
Every fortnight apply a standard houseplant feed that is high in both potassium and phosphate.
Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), choose one where nitrogen has a low value.
Winter
Winter-Spring · Indoors
Water lightly in winter
The soil should remain just moist during the cold months when the plant is not in growth. Trickle a little water onto the soil surface every couple of weeks if the soil is dry. Do nothing if it is moist.
The roots remain active in winter and benefit from small amounts of moisture so they don't become completely desiccated.
