The genus Saxifraga is directly related to the family Saxifragaceae. It includes more than 400 species of herbaceous plants, among which most are perennials and the rest are one- or biennials. It prefers to grow in nature in places with a harsh climate. Thus, this plant can be found in the subarctic areas, in the Alps, east of Greenland, as well as in the western and eastern parts of the Himalayas. It prefers to settle on stony embankments, in crevices of rocks, on masonry walls, but it can also be found in lowland meadows.
The roots are poorly developed because of the soil in the places where this plant prefers to grow. The root system is practically lobed, but there are a few small spines. The foliage of almost all species of plants of this genus is either located directly at the very surface of the soil, or gathered in dense root rosettes. Its flower stalks are long and solitary. They emerge from the middle of the rosette, which consists of leaves.
The tassel-shaped inflorescences are small-flowered. The florets have 5 petals and are most often radially symmetrical. It blooms for a very long time, about 3 or 4 weeks.
And other characteristics of stone breakers vary greatly in different species. For example, the height of a shrub can be two centimeters or 100 centimeters.
Leaflets can be both pectinate and long-petioled. Their edges can be smooth or significantly rugged. Flowers may be painted in different colors. They also come in very small and plain-looking sizes, but there are also very large, showy flowers with rich color. The petals come in both narrow-lanceolate and rounded shapes.
Brief description of cultivation
- Flowering. From late spring to late summer.
- Lighting. Bright diffused light.
During active growth - 20-25 ºC, in winter - 16-18 ºC, but green-leaved forms are more comfortable at 12-14 ºC in winter.
- Pouring. From March to October - regular and sufficient, then watering is gradually reduced to a minimum, so as not to dry out the ground lump.
- Humidity of the air. In spring and summer in hot weather, it is advisable to spray the plant with water at room temperature.
- Feeding. From spring to autumn - 2 times a month, and in winter - once every 6-8 weeks with a weak solution of mineral fertilizer.
- Dormant period. From October to the end of winter.
As roots fill the space of the pot. Several plants are usually planted in one pot.
- Substrate. Of equal parts sand, peat, mulch, and leaf soil.
- Pests. Thrips, mealybugs and spider mites.
- Diseases. Root rot.
- Properties. In folk medicine, the plant is used for medicinal purposes as an antipyretic and anti-inflammatory.

Home care of stonecrop
Can grow in semi-shade as well as in bright, diffused light.
Direct sunlight should be avoided. Otherwise, the leaves lose their succulence, becoming flaccid, and the color pales. To place indoors, it is recommended to allocate windows located in the western or eastern part of the room. Can also be kept at a north-facing window, but the variegated forms will loose their color in this case.
When growing actively, it needs a temperature of 20 to 25 degrees.
If it gets very hot indoors, take it outside for example in the garden or on the balcony. If this is not possible, the room should be aired as often as possible. In winter the plant can have a dormant period and during this time the stone flower needs to be at a temperature of 12 to 15 degrees. If the room is cold, watering should be more sparing as water evaporation slows down in this case. Stagnant water in the soil should be avoided under any circumstances, as it has a negative effect on the roots and may also promote rotting.
Water only with soft, clear water at room temperature.
Not too demanding of air humidity and very well suited to apartment conditions, but only if a cool overwintering environment is provided. If it overwinters in the warmth it should be put away from heaters and systematically sprinkled with lukewarm water. Spraying is also necessary on hot summer days.
Suitable soil must be light to medium nutritious, air- and water-permeable, with neutral acidity.
Only cotyledon rockery needs acidic soil. A suitable soil mixture for the other species is very easy to make. It is necessary to mix 1 part of leaf soil and 2 parts of clay and sod soil with ½ part of coarse sand. Also add one-fourth or one-fifth of the total volume of fine claydite or gravel into the mixture.
For planting stonefly need low, wide pots.
Planting several rosettes in one container is possible because the roots are small and do not take up much space. Do not forget a good drainage layer, which will help prevent fluid stagnation in the soil.
It reacts negatively to large amounts of fertilizer in the soil. It is recommended to fertilize only once a season. A multi-purpose room plant fertilizer should be used.
It is undesirable to use fertilizers that contain nitrogen because they provoke active leaf growth.
Potting out stonefly
Potting out when necessary, usually if the bush grows strongly and does not fit into the pot.
Home garden #19. STONEOMCA. Transplanting
Can be propagated by seeds as well as by daughter rosettes.
The rosettes can be planted immediately in a permanent pot.

Pests and diseases
Spider mite, powdery mildew, and thrips can settle in. If infested, treatment with insecticides (fitoverm, actellic) is recommended.
If the plant is not cared for properly, a variety of rotting can occur. So, for example, it can occur due to cold air with high humidity or as a result of overwatering. If the root system has rotted away, the remaining intact stem can be re-rooted. First clean off the rotting mass and treat with fungicides.
Stypes of stonecrop
Stonecrop is most commonly used for growing in rockeries as well as alpine slides in the park and garden.
However, there are small species that can be grown at home. Hence, these species include all of the following.
Also commonly referred to as a climbing or scion stone (Saxifraga sarmentosa), this species is the most popular and often climbing as an ampel plant. In the wild it is found in Japan and also in China. This perennial plant has a dense, leafy rosette.
Leaflets are long-petioled, with little pubescence. Shrub in cross section, and in height can reach from 20 to 50 centimeters. The leaf has a rounded shape with a heart-shaped base and a broad-shaped edge. Its diameter is about 5 to 7 centimeters. The front side is dark green with pale strips of veins, while the underside is burgundy green.
In the same color shade are painted pedicels, petioles, and even thin, long stolon shoots, which are airy offshoots, "whiskers", the tips of which are small daughter rosettes. If the stone flower grows as an ampelous plant, the length of its stolons can range from 60 to 100 centimeters. Note that each of the individual daughter rosettes is capable of having its own stolons.
This plant blooms from May to August. The small flowers are of little ornamental value, but they have a unique calyx which has no symmetry at all.
Thus, the 3 small petals on top have an ovoid shape and their tip is narrowed. They are colored pink and also on their surface is a chaotic arrangement of small maroon spots. At the bottom are two larger petals, colored white. They often vary in size.
The species has several varieties.
The most popular:
- Harvest Moon ("Harvest Moon") - leaf coloration pale, green-yellow.
- TricolorThis variety is mottled and each leaf has a rather broad whitish-pink edge.
In nature you can find it in the Alps. It is the most beautiful of all the stone breakers (during flowering and in normal times). Its very dense leaf rosette is very similar to a succulent such as the echeveria.
The thick green leaves are cellless and are lingual or obovate in shape. They are nearly 10 centimeters long and about 2 centimeters wide. The finely serrated edges are covered with a whitish, thick calcareous patina, which is produced by the leaf itself. The surface of the glossy leaflet also has a small calcareous patina. Flowering begins in May or June.
At that time, a lush heavily branched peduncle emerges from the middle of the rosette and holds a pyramidal bunch with a great number of star-shaped flowers. This bunch is several times larger than the leaf rosette itself. Its approximate size is 60 centimeters long and 40 centimeters wide. The flowers are painted pinkish-white in a regular star shape. However, there are now varieties with a different color of flowers.
Arends' stoneberry (Saxifraga arendsii)
This hybrid species is quite complex and has a large number of different varieties. The lobed, glossy leaves are deeply dissected and almost cellless. They are clustered in small leaf rosettes. Over time, the plant proliferates, resulting in very dense thickets somewhat similar to moss. Due to this fact, this species has received another name in the people, namely, "mossy stonecrop".
The small-flowered inflorescences have several fairly large, regularly shaped flowers. The petals are broadly oval in shape and can be colored yellow, white, pinkish, and various shades of purple and red. The color of the flowers depends on the variety.
This plant, which prefers to grow in areas with a rather harsh climate, does quite well in room conditions. However, there are still a few things to be considered for its successful cultivation.
