Polyanthus is a fantastic winter flowering plant, they come in an array of lovely colours and bi-colours. Have a look through the photos for a colour that you like. Their flowers sit upon flower stems of around 15-20cm high which gives them a real eye catching look and makes them perfect for planted containers, borders and raised beds. Polyanthus will flower right through to the spring, take out the main flower stem which it has finished blooming to encourage new ones to shoot up and flower. Polyanthus are hardy plants and will survive a frost, their flowers may not if it is a really hard frost. If kept fairly close to your house this isn't much to worry about.
These plants are grown in 1 litre pots so they are a decent size and well-established.
