What flowers are suitable for planting on graves this season?

Scutellaria barbata, also known as sunflower. Never mind. Plants are not tall, which will not affect the surrounding landscape, and weeds will not appear in winter. Scattered seeds will germinate and grow on their own in the next spring, and flowers will open one after another, which will be loved by everyone. Even if someone likes to pick a few flowers, it doesn't matter to the flowers.
