It flowers in June and July. The best mode of propagating it, is to, sow the seeds on the borders in patches, where the plants are to remain; thinning them when they come up, so as to leave only two or three together.

They continue to blow through most of the summer months. It is a very proper plant for a wall or piece of rock-work; care must be taken, however, not to sow too much of the seed in one pot, as it spreads wide, but it may easily be reduced at any period of its growth, as it does not creep at the root. The specific description in the _Hortus Kewensis_ above referred to, admirably characterizes the plant, but surely at the expence of its generic character. [102] CAMPANULA SPECULUM. VENUS'S LOOKING-GLASS. _Class and Order._ PENTANDRIA MONOGYNIA. _Generic Character._ _Corolla_ campanulata, fundo clauso valvis staminiferis. _Stigma_ trifidum. _Capsula_ infera, poris lateralibus dehiscens. _Specific Character and Synonyms._ CAMPANULA Speculum caule ramosissimo, diffuso; foliis oblongis subcrenatis, floribus solitariis, capsulis prismaticis. _Linn.
