Violas are a diverse group of plants. The flowers are roughly similar across all species, but some are annuals ( last only one growing season ) and some are Perennials ( lasting more than one season ). Here, we focus on the Annual variety. These have many common names, like Pansies, Johnny-jump-ups, etc and there are many hybrids available as seedlings in Nurseries and Garden Centres. They come in a fantastic range of colours and combinations of colours. Plant them in a sunny spot. They really are like "eye candy" !! I saw these Violas growing in pots inside a carport while on a walk around the suburbs.
Primula are also a great Annual plant that is available for Winter planting. These prefer a semi-shaded spot out of the hot sun. Colours available include crimson, pink, white,blue and purple. They grow and flower quickly to give a beautiful display, and they also self-seed, so you are likely to continue to have them year after year. There are also Perennial Primulas , but they are not nearly as popular as the annuals. These Prumula were growing in pots at a Garden Centre in Northern Sydney.
