It’s the Autumnal Equinox. At 2:50 AM EDT the Sun passed the equator and the Southern Hemisphere welcomes Spring. Here on the Canadian Prairies it has felt ‘fallish’ for a few weeks. The days are much shorter, we’ve had a few nights get as low as 2o Celsius (35oF.) with light frost in a few areas. Trees and shrubs are changing colour, leaves are already dropping, birds and butterflies have been gathering to migrate.

What does every Fall garden need? Fall blooming perennials. Those perennials that start blooming late, and can bloom right through light frosts, are a joy to have now. For Zone 3 gardeners look for hardy grasses, Mums (Chrysanthemums), Asters (Asters), Black-eyed Susan (Rudbeckia), Coneflower (Echinacea) and one of my favourites, Sedum.
If you have deadheaded summer blooming perennials you will likely get a second flush of flowers from such as Sage(Salvia), Russian Sage (Perovskia), Speedwell (Veronica) and even Bleeding Heart (Dicentra) may make a comeback as the weather cools. As plants are on sale at local garden centers, it’s a good time to indulge.
It’s not just the beauty of Fall colour; pollinators, other insects and birds really need this source of food. Monarch butterflies will feast on nectar before beginning their migration. Birds will fatten up on seedheads of grasses and flowers.
Get out the plaid clothes, grab a pumpkin latte or muffin and enjoy the Fall garden!
