MISSOURI BOTANICAL GARDEN BULLETIN 29 
Cycas revoluta, the so-called “sago” or “funeral palm,” while 
not a true palm, is a useful house plant. Among the serv- 
iceable and attractive foliage plants should be mentioned the 
screw pines (Pandanus), Siiokosistaeen: “leopard” or “gold 
dollar plant” (Farfugiwm grande), dracaenas, araucarias, 
or Norfolk Island pines, silk oak (Grevillea robusta), 
English ivy, sweet olive (Olea fragrans), century plant 
(Agave americana), Phormium tenaz, umbrella plant (Cy- 
perus alternifolius), Papyrus antiquorum, lemon verbenas, 
pepper plants, and aspidistras. Ferns doubtless constitute one 
of the most attractive classes of foliage plants and despite 
their usually very delicate appearance, many of them can be 
grown successfully in the house. The following are recom- 
mended: Nephrolepis Whitmanni, N. Scotti, N. Scholzeli, 
N. Elmsford, and N. “Roosevelt.” The Boston fern, and 
the many varieties derived from it, nearly always do well 
in the house, and under particularly good conditions, even 
the more tender varieties succeed. 
_ Except where unusually favorable conditions can be pro- 
vided, as in a conservatory, considerable difficulty is usually 
encountered in growing and bringing into blossom flowering 
plants. More frequently such plants are obtained elsewhere 
and are brought into the house from time to time when in 
bud or in flower and thus made a part of the window garden 
only during their respective flowering seasons. But despite 
the frequently poorer results, it is highly desirable to grow 
flowering plants to maturity in the house because of the 
pleasure derived from watching day by day the process of 
gradual development. Among the plants which may be 
more or less successfully grown and flowered in the house 
may be mentioned begonias, camellias, rose mallows (Hi- 
biscus sinensis), fuchsias, geraniums, heliotrope, petunias, 
callas, primroses, snapdragons, cyclamen, daisies, impatiens, 
abutilons, thunbergias, stocks, and verbenas. While many of 
these can be grown directly from the seed it is perhaps advis- 
able in most cases to obtain the young plants from growers. 
In addition, many plants, such as poinsettias, Lorraine be- 
gonias, azaleas, chrysanthemums, freesias, ixias, oxalis, 
euphorbias, lily-of-the-valley, tulips, narcissus, ete., may be 
obtained when in bud, but long before the color in the 
flower is apparent, and matured in the house, provided 
proper care is given them. 
Some of the plants which are frequently killed by frost’ 
when in the prime of their flowering season can be potted 
and brought into the house prior to frost injury and main- 
tained in a blossoming condition for weeks after those 
remaining out of doors have been killed. Among these may
