Plants for Alkaline Soils: Plants for alkaline soils are those that survive in a soil that has a pH level above 7. A pH of seven is called neutral and is suitable for most plants, but when our substrate has a pH level above seven, it is said that the soil is alkaline or sweet, being not suitable for anti-limestone plants, but yes, very suitable for plants such as lilacs, Clavelins, clematis, and wallflowers.
Beautiful Plants With a Lot of Colors That Will Survive Alkaline Soils
In the long term, whatever we do, there is no way to convert an alkaline soil into an acid soil and therefore any acidophilic plant can not thrive under these conditions, that is why having a list of plants for alkaline soils is a very good one idea when planning our garden.
The excellent news is that this type of soil often has very good drainage and heats up quickly in spring. If we add a good amount of organic matter, we can manage to grow a large variety of plants.
The organic matter contributes to that the nutrients are more accessible, favors the availability of the water and in addition, it nourishes the plants, always in its just measure, it is necessary to be careful with feeding them in excess.
8 Plants for Alkaline Soils
The Anemone Pulsatilla requires a soil that has a very rapid drainage and lots of suns. It is ideal for a rock garden, although it grows very well in many places. It is an easy plant to care for and requires little risk.
Within the bluebells, we have high and low varieties. They are plants that adapt very well to these pH levels and offer splendid blooms.
We can locate both full sun and half shadow and the risks should be moderate.
Clematis grows especially well in limestone soils. Within the different cultivars, there are three highly recommended climbers, those are the ‘Montana’, the ‘heracleifolia’ and the ‘integrifolia’
Depending on the cultivars they like a partial or total sun. The risks, in general, must be moderate.
The Clavelinas like the dianthus’ deltoids, the ‘armaria’ or the ‘barbatus’ is particularly ideal for filling gaps in sunny places. They are usually annual and easy to grow.
As I said before, they go in the full sun and require regular watering.
The scabiosa combines very well with a wide variety of plants. It is a perennial plant that forms an interesting bush and whose flowering occurs in summer, usually lavender blue, although there are hybrids of white and lilac. It is ideal for beds or borders.
We must place them in full sun and the risks should be rather scarce
The variety ‘Hibernia’ is one of the best trees for limestone soils. Sorbus aria can reach a large size and the cultivar ‘Lutescens’ is more compact.
Its location should be in full sun in fertile soils, moderately humid, but very well drained.
Lilacs are particularly beautiful during the spring. The cultivar Syringa meyeri ‘Palibin’ is ideal if we have a small garden. We must remember that for it to flourish in all its splendor, the climate must have very cold winters.
It has the advantage of enduring cold very well and needs watering two to three times a week
It is cultivated mainly by its felted leaves and its spikes of yellow flowers that appear during the summer and at the beginning of autumn, for example, in the cultivars ‘bombyciferum’ and ‘Helen Johnson’.
We can locate both full and partial sun and water it moderately.
