Centaurium genus plants are low growing hardy annuals that reach up to 20 cm (8 inches) in height.
They are known by the common names of Canchalagua, Mountain Pink and Centaury.
They flower in the summer with red of pink flowers and make ideal species for rockeries or for growing in borers.

When growing Canchalagua outdoors from seed,they should be sown in a partially shaded part of the garden into a light sandy soil in the middle of spring.
First sow the Centaurium seeds onto the soil surface, then lightly cover.
The seeds normally take about three to eight weeks to germinate and should be spaced at a distance of 20 to 30 cm apart (8 to 12 inches).
