The foliage plants depend very largely for their beauty upon making a rapid, unchecked growth and being given plenty of sunlight. In many of those having multi-colored and variegated leaves, the markings under unfavorable conditions of growth become inconspicuous and the value of the plant is entirely lost. Therefore, where the proper conditions cannot be given, it will be far wiser to devote your space to plants more suited to house culture.
Aspidistra, araucaria, Pandanus and the rubber plant are exceptions; two of them being remarkable for their hardihood under neglect and ignorance. While many of the foliage plants will live under almost any conditions, it must be remembered, however, that the better care they receive the more beautiful they will be.
Achyranthes—Achyranthes are still popular as bedding plants, as they furnish good coloring. They may be used as house plants also, but in my opinion are a little coarse. Take cuttings in August for new plants and keep on the warm side and rather dry in winter.
Alternanthera—These little plants are unique and brilliant, and a few will be worth having in any collection. They make dense, shrubby miniature bushes a few inches high, very attractively colored. Take cuttings in August; give rich soil, on the sandy side, plenty of light and heat.
A. versicolor has leaves bearing a happy contrast of pink, crimson and bronzy-green. Tricolor is dark green, rose and orange. There are numerous other attractive varieties.
Anthericum (A. variegatum)—The foliage is shaped like a broad blade of grass and very prettily bordered with white. Of the easiest culture, doing well in the shade. Propagated by division. A. medio-picta is another variety, often considered more attractive than the above.
Araucaria—The several araucarias should be much more widely known than they are. Their beauty has made them popular as Christmas gifts, but most of the fine specimens which leave the florists during the holiday season find their end, after a few weeks in a gas-tainted, superheated atmosphere, with probably several times the amount of water required given at the roots, in the ash barrel. They are, when one knows something of their habits of growth, very easily cared for. Little water in winter, and a cool even temperature, are its simple requirements.
The araucaria is, I think, the most beautiful of all formal decorative plants. Its dignity, simplicity and beautiful plumelike foliage place it in a class of its own. The branches leave the main stem at regular intervals, in whorls of five, and the foliage is a clean soft green, lighter at the tips. Propagated by cuttings from leading shoots, not side shoots.
The two varieties ordinarily used are A. excelsa glauca and A. e. robusta. Some time ago I saw a specimen of a new variety, not yet put on the market, and the name of which I have forgotten. (I think it was stellata) The outer half of each branch was almost white, giving the whole plant a wonderful star-like effect.
Aspidistra—The aspidistra is the toughest of all foliage plants—if not of all house plants. It has proved hardy out-of-doors as far north as Philadelphia. The long flat leaves grow to a height of eighteen to twenty-four inches, springing directly from the ground. Its chief requirement is plenty of water during the growing season. New plants are readily obtained by dividing the old roots in February or August.
