These plants are easy — they like to go into warm soil and hang for a few weeks, then get cold, and then germinate in the spring for a full season of growth. Many of them are natives, a few are ornamental grasses, and there are options for cut flowers, meadow gardens, container plantings, or mixing and matching to go with your garden style.
Briza Media - Perennial Quaking Grass - This is a great plant in the garden as well as for cut flowers. The pretty seed heads of this grass rattle in the slightest breeze.
Pimpinella major 'Rosea' - Greater Burnet - If you love the romantic country look of Queen Anne's Lace, you will likely enjoy Pimpinella as well. Instead of white, these flowers are pretty shades of pink
Zizia aptera - Heartleaf Golden Alexander is a native plant that grows naturally throughout much of the US (excluding the extreme south and southwest). Stems with yellow flowers rise above heathly green leaves.
Allium obliquum - Twisted leaf garlic - White flower balls top 12 – 15 in stems. These can be grown from seed as well as propagated by bulbs. The seed needs time to germinate in warm soil (now), then a cold period, and will grow next year.
Deschampsia flexuosa - Wavy Hairgrass is also a native grass, and it thrives in dry shade. It is not too tall (topping out at 18") and it is quite elegant.
