Autumn sowing

What should you sow in autumn? Garlic and alliums, which need a cold period to develop properly, as well as trees, shrubs, and perennials with hard seeds: sown directly in the ground from October onward, they benefit from 100% natural winter stratification. It is also the season for hardy flowers (cornflower, poppy, nigella) for earlier flowering the following spring. Open-pollinated, non-hybrid, untreated seeds.
