OXALIS.
The winter blooming varieties are admirably adapted for hanging-pots, and being cheap and very easy of cultivation, they ought to be in every dwelling. There are one hundred and fifty known varieties, though our catalogues rarely name half-a-dozen. Some are strictly winter bloomers, others flower only in summer, and some blossom the year round. The floribunda varieties belong to this class of perpetuals. Ortgiesi also, which is a wonderful bloomer, and on account of its erect growth, is admirably adapted for pot culture. It is a new and somewhat rare species from Brazil. It often grows eighteen inches high, and in good form. The upper side of the leaf is rich olive green, and the under side bright violet purple. The flowers are quite small, yellow, and borne in clusters. The special beauty is in the foliage.
Floribunda alba and rosea have tuberous roots. The foliage is very strong, and the clusters of bloom are borne on long foot-stalks starting directly from the tuber. A single small tuber will often have a hundred open flowers at a time. They are from one-half to three-quarters of an inch in diameter. This variety can be obtained and planted at any time of the year. It is admirably adapted for baskets or a hanging-pot.
Oxalis acetocella is the true shamrock of Ireland. Flowers are white, borne on stalks two to four inches high. Versicolor is a winter bloomer; color white, with bright pink margins to the petals; requires sunshine; the flowers will not expand in cloudy weather. Floribunda has no such freaks, but smiles in the storm, as well as the sunshine. A lady writing to Mr. Vick becomes enthusiastic over her Oxalis. She says: "The sixth of last October I planted a bulb of Oxalis versicolor, and it is just beginning to bloom. And oh! what lovely flowers; delicate and perfect in form, pure white, with just the faintest tinge of yellow in the center, and beautiful crimson stripes on the outside. The plant also is of a very graceful habit, bearing its tuft of small leaves, and clusters of flowers on the top of a short, slender stem. It seems strange that so small a bulb can produce such beautiful flowers."
Of Bowii she thus writes: "A year ago last October I planted a bulb of Oxalis Bowii in a small bed. The bulb was so very small that I did not believe the flowers could amount to much, but was soon most agreeably disappointed. Such a mass of flowers on one small plant I had never seen before, and such large, bright-colored flowers! Many stopped to admire it, and ask its name. It continued to produce a mass of flowers the entire winter and part of the spring, until the sun became very hot. From this one bulb I obtained eight, which I wrapped in paper and kept in a dry place. About the first of August they commenced growing, and so I planted them, and the first of September they were in full bloom, though the flower grew large as the days became less hot, until they were nearly as large as Petunias. The soil in which they grew was mostly sand and rich surface earth from the woods, and I sometimes watered them with weak soap-suds."
Mr. Vick, to whom we are indebted for the most of our information on this subject, says that this variety has large, thick, fleshy leaves, and large, bright, rose-colored flowers, the largest, indeed, of any of the cultivated kinds.
In his illustrated article he gives an engraving of one named Cernuus plena, the flowers of which resemble double Portulacas; erect, borne in clusters. We regret that he gives no reference to this variety whatever. It must be a rare sort, probably not in the market here.
