until it attains its maximum size, which in this country seems to be about 

 ten feet. When grown in the open it is of a round, compact shape, and 

 as it flowers before the leaves appear it is a perfect mass of snow-white 

 blooms. The petals are narrow and in several rows, whence the specific 

 name of stellata. It remains in bloom for two or three weeks and the 

 flowers are succeeded by the shining green leaves. The fruit is bright 

 red, which adds to its attractiveness in the fall. It is perfectly hardy, at 

 least as far north as Massachusetts. It is now in its perfection in the 

 Washington parks. 



Nasturtiums for the Greenhouse. — Although a very familiar plant, 

 amateurs will find the nasturtium a very satisfactory winter plant for a 

 small greenhouse. The tall-growing varieties may be grown in small 

 pots and trained about a pillar, a support in the pot, or permitted to hang 

 down over the edge of a bench or shelf, while the dwarf forms make very 

 pretty subjects for hanging baskets or when grown as specimen plants in 

 pots. All they need is good rich soil and plenty of water and they will 

 bear a profusion of bright-colored flowers for months and may be put out 

 in the border in spring when the weather is mild and will continue bloom- 

 ing all summer. By removing most of the leaves the tall-growing variety 

 may be grown to a length of twenty or thirty feet and trained around the 

 greenhouse. 



Streptosolen for the Greenhouse. — A very pretty shrubby evergreen 

 plant for cool greenhouse culture is Streptosolen /amesonii, or Browallia 

 Jamesonii as it is sometimes called. It was introduced from Colombia in 

 1847 and is of the easiest culture, requiring rich rather porous soil and 

 plenty of water. It grows several feet in height and if not pruned makes 

 a bushy growth, but it may be trained against a pillar or other support. 

 The leaves are small, ovate in shape and strongly veined, and the tubular 

 flowers, borne in large terminal panicles, are at first deep lemon-yellow, 

 soon changing to reddish-orange. They remain for six weeks or more, 

 and the little bush fairly glows with the showy blooms. It is readily 

 propagated by cuttings, and blooms the first year. 



Management of Greenhouses. — The Agricultural Department of the 

 State of Pennsylvania has recently published, as Bulletin 97, a very 

 valuable pamphlet of forty pages on the management of greenhouses, by 

 Edwin Lonsdale, the well-known and successful grower of Wyndmoor, 

 Pa. After treating of the construction of greenhouses, their heating, 

 watering, and management, he speaks at some length of rose-growing, 

 giving directions for forcing and general growing. There are also short 

 chapters on the ordinary diseases of plants, as roses and carnations, that 

 are grown commercially, and one on insect pests and the means of con- 

 fronting them.
