About this plant
These serene, upstanding, summer flowering bulbs have a cool reserved beauty that sets them apart in the busy multi-coloured sunshine of the summer garden. They have long sturdy flowering stems from which hang quantities of small white bells. Galtonia viridiflora has white bells with some green suffusion. They stand about a metre in height and flower between July and September. They generally look better planted in a group, as a single specimen just seems to disappear. These are grown in the Saville Ggarden in Surrey amongst Agapanthus and the two forms combine well.

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 - 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.

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.
