biennial ; and, like Zupinus Hartwegit, flowers from the end 
of June until destroyed by frost in the autumn. 
If treated as an annual the seeds should be sown as early 
as possible (February), so that the plants may have a long 
season before them ; but if managed as a biennial, the seeds 
should be sown the previous year, about the beginning of 
August; kept in pots protected from frost during winter, 
and planted out in the open borders about the middle of 
May. It makes large plants, growing nearly three feet high, 
and flowering profusely all the autumn.
