PENTSTEMON , in See also:botany, a genus of See also:plants (nat. See also:order See also:Scrophulariaceae), chiefly natives of See also:North See also:America, with showy open-tubular See also:flowers. The pentstemon of the florist has, however, sprung from P. Hartwegii and P. Cobaea, and possibly some others. The plants endure See also:English winters unharmed in favoured situations. They are freely multiplied by cuttings, selected from the See also:young See also:side shoots, planted See also:early in See also:September, and kept in a See also:close See also:cold See also:frame till rooted. They See also:winter safely in cold frames, protected by mats or See also:litter during See also:frost. They produce See also:seed freely, new kinds being obtained by that means. When See also:special varieties are not required true from cuttings, the simplest way to raise pentstemons is to sow seed in See also:heat (65° F.) early in See also:February, afterwards pricking the seedlings out and hardening them off, so as to be ready for the open See also:air by the end of May. Plants formerly known under the name of Chelone (e.g. C. barbata, C. campanulata) are now classed with the pentsterons.
