Specific Plant Information and Tips on growing Brachycome in the Garden
Brachycome iberidifolia: Swan River Daisy
Swan river daisies are a very popular annual in the garden, and this has led to many different varieties of Brachycome iberidifolia becoming available; these include: Mini Yellow; Mauve Delight; California Pink; Blue Zephyr; Purple splendor and Blue star. These plants are native to Australia and come into bloom in the cooler months from August to May; they do not flower in extremely hot conditions. In the Northern hemisphere they will come into bloom in the Summer and Autumn; though do not expect to see flowers when the weather is very hot.
Plants reach about 15 inches (40 cm) in height and should be spaced at about 9 inches (22 cm); if you are using the plants as part of a lawn edging then space at 6 inches (15 cm) apart. They can be grown in full sunlight or partially shaded conditions, and can tolerate dry soils. Ideally the soil will be rich and deep, and slightly acidic (though these plants are known to grow well in soils of pH 5.5 to 8).
Blooms do not tend to last long, so prolong blooming time by deadheading, and sow out seeds every three to four weeks in order to maintain a continuous bloom in the garden.
Brachyscome ciliaris: Variable Daisy
These perennials reach an height of 6 to 18 inches (15 to 45 cm) and are able to grow in full sunlight and partially shaded conditions. They bloom in summer and early autumn with rose or white colored petals and a black or yellow eye.
