Perennial gallardia - Gaillardia pulchella


A dozen species of perennial herbaceous plants, originating in North and Central America, belong to the genus Gaillardia pulchella. They are generally medium in size, and do not exceed 30-50 cm in height, depending on the species. The leaves are evergreen, quite thin, sometimes ribbon-like, light green in color, erect; plants tend to produce small carpets, similar to lush grass. Throughout the summer, long thin, erect stems sprout from the leaves, bearing solitary, various-sized flowers in the shape of a daisy. The center of the flower is yellow or brown, the petals are of various colors, in shades of yellow, red, orange and brown, often in several colors; the typical flower of gaillardia pulchella has a darker center, and lightens towards the tip of the petals, but there are many cultivars, some of which are pure yellow. To prolong flowering it is advisable to remember to remove the withered flowers. If desired, it is possible to cultivate gaillardias as annual plants, although in regions with not too harsh climate the leaves are evergreen, and therefore these perennials can be decorative even during the winter period.


Perennial gallardia plants are grown in a sunny place, but can withstand short periods of shading, but should be grown in places where they can receive a few hours of direct sunlight a day to allow them to develop vigorously. Generally they do not have big problems and they bear both the summer heat and the winter cold very well so they can be grown outside without problems and without the need to provide special shelters.


The specimens of Gaillardia pulchella do not require large amounts of water, and can withstand periods of drought even prolonged. For a good flowering it is advisable to sporadically water the plants of perennial gallardia during periods of extreme drought. In any case it is always good to wait for the soil to dry perfectly before watering it, leaving it well dry even for a few days. This kind of plants, in fact, does not tolerate the stagnation of water that can be very harmful and cause the onset of root rot.


The plants of Gaillardia pulchella grow without problems in any soil, as long as this has a good degree of drainage that allows the flow of water and does not allow water to form, very dangerous for the growth of plants of this particular tree species.


The reproduction of these specimens usually occurs by seed, in spring, even if the hybrid species do not always produce plants identical to the one that produced the seeds from seed; in autumn it is possible to divide the clumps, being careful to leave some well-developed roots for each portion practiced.
