The orchid flower, also called gaura, is a perennial herbaceous plant, native to North America. It has thin, slightly flexible, red-brown, very branched stems, 40-100 cm long; they carry numerous small leaves, of a reddish-green color; throughout the summer, until the first cold, they produce long spikes of pinkish white flowers, which bloom in succession. There are numerous cultivars of gaura, with pure white flowers, or pink or fuchsia. To prolong flowering it is good to remove the stems that carry faded flowers; leaving the flowers on the plant we will soon notice the fruits, small elongated pods, which contain numerous seeds, when ripe the pods open and scatter the seeds on the ground. To improve the compactness of the plant, and make it a small dense bush, it is advisable to trim the stems in mid-spring, or cut the entire plant 20 cm from the ground at the beginning of winter.
Place the orchid flower in a sunny place, or in the partial shade; if placed in a poorly lit spot by direct rays, the only ones gaura tend to produce fewer flowers. These rustic perennials do not fear the cold, and can easily withstand temperatures well below zero. In places with very cold winters most of the aerial part dries up during the winter months.
from March to October water regularly, when the soil is well dry. These plants can easily withstand even long periods of drought. In the vegetative period, provide fertilizer for flowering plants, every 25-30 days, mixed with the water used for watering.
The species of gaura need loose and well-drained soils, even arid; It is possible to grow them in any garden soil, as they adapt to any condition; attention to water stagnations, particularly harmful to the plant. If we want to grow orchid flowers in the garden, it is a good idea to make a hole in the ground and place draining and soil inside the plant to ensure optimum growth for the plant. Once this is done, place the plant well in the center, fill the hole with earth and compress the soil until it reaches the level of the surrounding soil.
If we wish to reproduce our gaura and obtain new orchid flowers, we will have to proceed with the multiplication of Gaura by seed, in the month of febrarium in a seedbed, or directly at home, in March or in September. This is because it is still difficult to find plants of gaura in Italian nurseries or in the best garden centers because of the peculiarity of the plant.
As for the multiplication by head, if the night temperatures are particularly low, it is advisable to place the pot or container of our new seedling in a place sheltered from currents and intense cold.
