the Verbena. From the success of my pyramid I am confident 

 it would be a pleasing and striking object. In a flat bed of this 

 plant, I find it does not flower very freely during summer, unless 

 the bed have a substratum of drainage made of broken pots, 

 stones, &c. ; and it is impossible to keep it through a mild winter 

 in the open air, without a good drainage, the cold damp of the soil 

 destroying the tender roots. I find that the plants survive the 

 open air on the sunny side of my pyramid remarkably well ; and 

 some plants which had grown on a rockwork also endured the 

 winter without any injury whatever. From these circumstances, 

 I am persuaded, it requires a dry situation for the roots through 

 winter, and if this be attended to it will answer. With a small 

 flat bed I had, I placed a willow hurdle, (an old hamper lid,) 

 about six inches below the surface at the lime of planting, and 

 at the end of October, I took up the plants and soil entire upon 

 the hurdle, and placed it in a cool part of my greenhouse, and it 

 continued to flourish through winter. Early in March, I took ofl' 

 a considerable quantity of side shoots and rooted runners potted 

 them into small pots (60's,) and put them into a hotbed for a fort- 

 night; they struck into the soil immediately, and furnished nit 

 with an abundant supply for planting out of doors in April. I 

 tried to keep young plants through winter in small pots, but could 

 not succeed with any that were taken oft' the old plant later than 

 the last week in August. Flora.

ARTICLE Till.— On Verbena pulchella, rar. albijiora. 

 By N. B. 



A friend of mine sowed seeds of Verbena pnlchella in the spring 

 of the present year, and succeeded in raising four plants, which 

 have bloomed ; two of them are varieties with white flowers, and 

 prove a roost pleasing addition to the flower-garden plants. The 

 plant and flowers give a very lively effect, and will be suitable for 

 a bed, contrasting admirably with Verbena chamoedrifolia. 



In order to bring the above new variety into notice, as well as 

 to induce other persons to the very delightful pursuit of attempting 

 to raise new varieties of plants, I forward this for the Cabinet, and 

 also a drawing of the plant in bloom. N. B.
