Flowers are seen as a gesture of love or friendship and may have a special symbolism attached to it. So in the spirit of all things spring, we've decided to choose one flower a week for the month of September. 

This week, it's all about asters.

Asters are daisy-like perennials with starry-shaped flower heads, and come in a variety of purples and pinks. It is regarded as a feminine flower representing positivity. 

There are many species and varieties, so plant height can range from 20cm to 2.4m - depending on the type. The plant can be used in many places, such as in borders, rock gardens or wildflower gardens. 

They prefer cooler climates with relatively wet summers. They enjoy full to partial sun in which to thrive. 

According to horticulturist at Granny Mouse Country House & Spa, William Brown: “Asters should be planted in early to mid-spring in fertilised and moist, well-drained soil and water thoroughly”.
