Others are biennials producing a number of leaves on a very short stem in the first year, and in the second sending up a flowering shoot at the expense of the nourishment stored in the thick tap-root during the previous season.
- Biennials live through one winter period.
The number of biennials is not large, but a few very desirable garden plants, such as the following, occur amongst them: Agrostemma coronaria (Rose Campion): hardy, I ft., bright rose-purple or rose and white.
Dianthus chinensis (Indian Pink): half-hardy, I ft., various; flower earlier if treated as biennials; must be protected from frost.
In the last week, sow hardy annuals in the borders, with biennials that flower the first season, as also perennials.
