I've been considering having the lower field and the weedy hillsides here managed by someone other than myself... and that would mean mowing and gas trimming. If the lower field were worked for sunflowers or other 'crop', that would mean less mowing for sure. I think that twice a season, well timed to clear seed heads, would keep it all down to a dull roar. It's a challenge.
The warmer niche zones in Ontario closer to the Great Lakes are surprisingly favourable to over wintering hardier plants like pansies - in fact at my last digs a few plants did survive under snow cover but were leggy and didn't thrive the second season. I've had great luck with growing them from seed started after last frost.
Coleus is frozen this morning. When the sunshine warms the stems and the freeze is out, I'll know what stands or falls following the first 'killing' frost of the season here. Nasturtiums, begonia foliage, coleus, some varieties of cosmos will be lost ... not sure about the gaillardia.
I will say that the frost-topped bee balm and amaranth, the frost-rimmed cosmos - are beautiful in the first light.
Yesterday, I cut all the glads and took some zinnias as well for the house - a last hurrah of colour. I took some cuttings from the coleus and brought in the huge English ivy and one pot of chenille (red hot cattails). Last week I gave away all of Busby's flowering plants that had thrived outside all summer. Hunkering down for winter. Today I continue with the shed contents and may just start up the snowblower just for the heck of it
