About this plant
This plant has large heart shaped leaves that are beautifully marked. They are silvered across their surface with green veining and a green edge, cool, elegant and appealing. There are open branching heads of small blue flowers in spring and early summer. This will tolerate dry shade but it needs a cool site with some moisture and nurture to achieve its best. It stands around 50cm (20in) in height when in flower.

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.
Summer

Feed a general fertiliser
Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.
Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.
