One of the plants we can consider putting in our garden if we need to wallpapering partition walls, camouflaging them in the green, it can be Aubretia. It is a herbaceous plant that is also very suitable for rock gardens. Let's go and discover its characteristics and learn how to best cultivate it.
This perennial and evergreen plant, cultivated for ornamental purposes in the ground and in pots, belongs to the Brassicaceae family. It comes from Europe and is therefore comfortable in our climates, in Italy as well as in other less warm and Mediterranean countries.
Being a plant that is used to wallpaper walls or create green carpets, it does not reach great heights, on average it reaches ten or fifteen centimeters. When we choose aubretiain fact, what interests us more than anything else is to form cushions of leaves, which bloom in due course. The foliage is perfect for this purpose because it is very dense thanks to the many herbaceous stems that compose it, covered with small gray-green leaves.
They are very small but consistent leaves, almost leathery and covered with a light down that makes them opaque in color.
From spring until the end of summer, this plant produces flowers and the cushion we have created with patience is filled with color. White, pink, red, purple and blue with single or compound corolla depending on the species. The flowers are very small but numerous, so they can be noticed, forming a sort of very pleasant colored spot.
The problems most felt by this plant are two: the attacks of snails and water stagnation that can cause root rot. For the water stagnation, we will soon see what precautions to take so that they do not form, while for snails, it becomes necessary to get traps, especially if we are growing Aubretia in the open ground. If, on the other hand, we are keeping the plant in a pot, we must empty the saucer, after about half an hour from watering.
To find the right position for this plant it is very important to evaluate the amount of sunlight that would reach it. On the one hand it needs a lot of light to bloom abundantly but on the other hand the roots must remain absolutely protected from the sun's rays. THE better places to cultivate it are those near the walls or some rocks that we can find in rock gardens. Being a European plant, it is quite accustomed to low temperatures and is not afraid of facing winter even by remaining in the garden and being discovered.
The best ground, just to avoid the water stagnation its enemies, it is a well-drained soil, even better if it is also calcareous, soft and loose. In any case, it is necessary to fertilize, from spring to autumn, every 15-20 days. The product to be procured is a fertilizer for flowering plants which we will then have to dilute in the water used for watering. Alternatively, we can distribute a slow-release granular fertilizer at the base of the head about every three months.
In summer and in periods very hot, watering must be very regular and frequent, while in the rest of the year, it is not necessary to exaggerate, indeed it is better to proceed in moderation, always to avoid root rot.
The multiplication can take place by seed or by division of the tufts. In the first case, the right season is spring, using the seeds we stored in the previous year. The seedbed can be useful if you do not want to depend too much on the external temperatures, otherwise we can also proceed directly to the home when the external temperature is pleasant and there is no risk of late frosts. It is important to position the seedlings well when they have produced at least three pairs of leaves.
To get the seeds, we can turn to gods gardening shops, there should be no problems, but even online you can easily find packs of seeds, even in the well-known Amazon. For multiplication by division into tufts we can choose the season spring but also autumn.
Year after year, when we realize that the roots of the plant begin to stay tight in the pot in which we have placed it, then the time has come for repotting. We can usually notice this because the roots begin to come out of the water drainage holes of the watering. To proceed with repotting it is necessary to obtain new soil, a larger pot and a lot of patience so as not to damage the roots when carrying out the transfer manually.
To improve flowering and encourage the emission of new basal shoots shorten the stems 10 cm from the base, pruning is essential. We usually proceed towards the month of February taking care not to compromise the flowering that is near.
