left, mini-plant Nephrolepis (Fern), a right Radermacher. Radermacher is a genus of plants of the family Bignoniaceae, native to Southeast Asia. This type includes fifteen species. We also find this plant under the name of Stereospermum. The genus name is dedicated to Jacob Cornelis Matthieu Radermacher, eighteenth-century Dutch naturalist who identified a large proportion of the flora of Java and Sumatra. Characteristics
The Radermacher are evergreen trees of varying sizes depending on the species, from 5 to 40 meters high. The leaves are bi-or tripinnate. The flowers, grouped in panicles, have a diameter of 5 to 7 cm, with a bell-shaped corolla tubular, white, pink, purple or bright yellow.
nontoxic plant - This small shrub has a light and air. Small shiny leaves are found in pairs and are bright green. They evoke those of the ash. Stem, at first green, becoming gray and woody shrub vieillit.Cet when the subject lives very long without great difficulty. This bloom plant does not bloom indoors. Growing moderately fast-growing, the Radermacher reach a maximum height of 1m pot. The light foliage of this plant the intended rather to be grown in isolation. Place it in front of a light colored background. Grow this plant in indirect light. A window exposed to the east or west should be fine. The sunlight burns the leaves and excess shadow that lie disproportionately twigs. The Radermacher is easy to grow if he finds a location with adequate light but no direct sun. By cons, it shall bear no air pollution. Do not place not in a kitchen where gas fumes or cooking does not suit him. Also avoid smoky places by smoking or other source of smoke ... If necessary, trim the plant in fall for it retains a very compact port. Temperatures between 21 and 24 ° C in summer and 15 to 18 ° C in winter are fine. Water moderately during growing season. Moisten the mixture well with each watering, but allow to dry on the surface before watering again. In winter, water just to keep the root ball to dry out completely. Perform regular liquid fertilizer once a month from May September. Repot in spring every 2 or 3 years. Use a soil-based mixture by placing a good layer of drainage at the bottom of the pot.

In all species of Fishbone, the fronds spring from an underground rhizome which is the upper visible and form a short stem and thick. The fronds are long and curved. They are divided into narrow leaflets alternating on each side of the spine. Under each leaflet, there are 2 rows of sporangia reniform, brown, and on either side of the midrib. All Fishbone produce many runners who are thin and hairy on the surface of potting mix and take root. The Fishbone is growing year-round if kept in the heat. This fern lives very long when grown under good conditions. Unlike most ferns prefer an indoor location semi-shade, the bright light Nephrolepis application but still no direct sun. When the temperature drops below 13 ° C, growth ceases. Not fall below 10 ° C. Above 21 ° C, humidity should be increased and drench is needed. Above 13 ° C, drizzle generously to keep the soil wet. The compost will be a good mixture of peat-based commerce. Most ferns require acid substrate (plants calcifuges). Multiplication is performed by sowing spores. It is made by producers who specialize in horticulture buy pots of young plants ready for potting. In summary, we can say that a spore gives rise to a prothallus (small leaf-like body shape of heart), which appear in the genitals. After fertilization must be done through water in liquid form, the prothallus gave birth to the first sling appears as a crook. As to the appearance of other fronds, the prothallus disappears and the plant has the appearance of a mature plant in miniature. Propagation by runners taking possession of seedlings is easier, each seedling being transplanted or potted separately in a terrine. Watering depends on the ambient temperature. Water must be free of limestone (calcifuge plant). The substrate is good soil, ferns special 'trade, it must have an acidic pH. Repotting is preferably in the spring when the roots fill the pot. Place the plants in a lighted area, but protected from direct sunlight. The runners can be removed if they interfere with the appearance of the plant. They are then recovered for propagation if they are sufficiently developed. Mealybugs can invade the plant. It must be treated quickly. When growing conditions are unfavorable physiological conditions can settle (browning or drying of leaves, crown rot caused by excess humidity in a temperature too low ...). Nephrolepis is used in the stew and indoor garden. In floral, foliage is enjoyed as a filling in floral arrangements.
