Plant details
This popular dwarf plant has long been used for edging formal beds, since the plants remain neat and compact throughout the season. It is also valuable for filling in gaps in borders and for containers of all kinds wherever fine shades of blue or pink are required. 'Southern Cross' is an old variety, but still in great demand for its ease of cultivation and its extra large clusters of fluffy pink flowers that last well on the strong plants. They are in fact tender perennials and may be potted up in autumn to continue flowering indoors in warmth.
