One of the many reasons I love Autumn is the Asters that suddenly make a colourful appearance. It’s weird, because they’ve been there all year, sending green stalks up through the meadow or at the edge of the field and sometimes even in the middle of the garden. Yet come September when the blues and purples and whites start to appear…. they are a perfect antidote to the masses of bright goldenrod, and the perfect side dish to the tree and shrub leaves that are starting to turn yellow and brown. Here are three of my favourites from the garden – Aster Symphyotrichum novae-angliae (New England Aster), Symphyotrichum oolentangiense (Sky Blue Aster) and Symphyotrichum ericoides (Heath Aster).
