Gloxinia planting and growing


Gloxinia. - Choice greenhouse tuberous-rooted, spring and summer-blooming perennials, sometimes seen in window-gardens, but really not adapted to them, although some skillful house-gardeners grow them successfully.

Gloxinias must have a uniform moist and warm atmosphere and protection from the sun. They will not stand abuse or varying conditions. Propagated often by leaf-cuttings, which should give flowering plants in one year. From the leaf, inserted half its length in the soil (or sometimes only the petiole inserted) a tuber arises. This tuber, after resting until midwinter or later, is planted, and flowering plants soon arise.

Gloxinias also grow readily from seeds, which may be germinated in a temperature of about 70 degrees. Flowering plants may be had in August if seeds are sown in late winter, say in early February. This is the usual method. After the bloom is past, the tuber is partially dried off and kept dormant till the following season.

It will usually show signs of activity in February or March, when it may be shaken out of the old earth and a little water may then be applied and the amount increased till the plant is in bloom. The same tubers may be bloomed several times.

Success in the growing of gloxinias is largely a matter of proper watering. Keep the dormant tuber just dry enough to prevent shriveling, never trying to force it ahead of its time. Avoid wetting the leaves. Protect from direct sunlight. Protect from draughts on the plants.
