The Draba aizoides is a small evergreen perennial plant, native to Europe and the Caucasus, quite common in the Apuan Alps. This species forms dense tufts made up of small linear leaves, about a centimeter long, of dark green color, which present a slight down on the lower page; in spring it produces thin, erect stems, 10-15 cm long, which bear 8-10 small golden-yellow flowers, with 4 petals, united in racemes.
The yellow flowers are very showy that appear from May to July depending on the area and altitude. After flowering on the plants appear fruits in the form of an elongated siliquetta measuring about 1 centimeter.
In nature these small plants develop between the cracks of the rocks, generally at medium altitudes; they are very decorative in rock gardens, for their showy flowering and compact appearance. Over the years the plant tends to spread on the ground, maintaining a compact, rounded shape. The Draba aizoides also develops on meadows and grazing meadows or rich in stony debris. This plant can be found practically all over Italy with the exception of the islands and regions of the south.
With regard to exposure, let us remember to place in full sun, or in partial shade; these plants do not fear the cold, but can be damaged, even seriously, by too hot, therefore it is advisable to shade them during the hottest periods of the year, especially if they are planted in places with very high summer temperatures.
Water the plants regularly, from March to October, especially during the hottest months of the year; during the period of greatest development it is advisable to supply fertilizer for flowering plants mixed with the water used for watering, every 20-30 days. We always check that the soil has dried between one watering and another to avoid water stagnation to the plants.
Like many other species also the Draba aizoides can suffer from too moist soil and accuse radical rot or other problems if the earth remains wet too long.
The draba aizoides plants preferably develop in calcareous, poor and rocky soils, and in these lands they are able to survive in an optimal manner. They need a light, soft and rich soil, very well drained. It is good to remember to add sand and a little gravel to the soil of the place where you want to place them, to favor the outflow of water and avoid stagnation.
The multiplication of the Draba aizoides occurs mainly by seed, in February-March, using the seeds of the previous year. If germination does not take place it can be favored by placing the container with the seeds in the refrigerator for a couple of weeks, in a plastic bag to keep the soil moist.
You can also try other methods of reproduction such as cuttings and offshoots that very often give excellent results and accelerate reproduction times considerably.
