Some plants which are considered to be perennials behave as biennials at this altitude. Those given below have proven themselves to be biennial in nature, developing leaf and establishing root systems during their first year of growth, but not blooming until their second year, following which they seed and die.

The following can be grown from seed, planted in the fall before the first big snow (your call!) Mix the seed with some cheap soil before broadcasting it, to provide something to which a seedling can adhere after germination. The moisture from winter melt helps seed to swell and germinate.

Siberian Wallflower Cheiranthus allionii
Fairly easily grown from seed, these plants produce multiple orange gold flowers. They like full sun, but appreciate some irrigation to get them started.


Sweet William Dianthus barbatus
Sweet William does very well at this elevation. It is suggested that they are grown from seed with some irrigation. They will provide a profusion of bloom from deep red to pink to white. En masse they look fantastic. At the end of the season they will produce lots of little black seed. To provide continuity of blooms, don't forget to ensure that some seed is planted each year. The flowers may be cut for the house.
