Moss stone breaker ∗ The 10 best care tips (Saxifraga x arendsii)

Origin and Distribution

The different forms of the hybrid moss saxifrage (bot. Saxifraga x arendsii) do not always have the same parent species, so that a specific assignment cannot be made. Strictly speaking, it is not a species term, but a collective term for different varieties of the garden saxifrage. Incidentally, gardeners divide the numerous breeds into sections for easier differentiation, whereby species such as the asthmaSaxifrage (bot. Saxifraga hypnoides) and the turf saxifrage (bot. Saxifraga rosacea) probably represent the parent species of most cultivated forms.

Incidentally, the botanical name Saxifraga x arendsii pays homage to the famous German gardener and Plant breeder Georg Arends, in whose nursery the first hybrid saxifrage breeds were created are.

use

Moss saxifrage belongs to classic rock garden planting and is a must in practically every stone bed. In addition, the undemanding perennial is very suitable for greening bare dry stone walls. Although the plant thrives best in bright locations, it is considered good shade-tolerant and can therefore also be planted in partially to shady beds as a foreground or border. The herbaceous plant looks very pretty as an underplanting of deciduous trees and cleverly conceals bald spots. Saxifraga x arendsii are also very suitable as grave plants. Moss saxifrage can be combined particularly well with various ferns and shadow grasses, but also with perennials such as bleeding heart (Lamprocapnos spectabilis), elven flowers (Epimedium), Cranesbill (Geranium), carnation (Armeria), Purple bells (Heuchera), Bergenia (Bergenia), Columbine (Aquilegia) or flowers of the gods (Dodecatheon) combine.

Appearance and stature

Depending on the variety, the moss saxifrage, which can reach heights of up to 15 or 20 centimeters, is evergreen Leaf rosettes, which over time develop into dense cushions through side shoots and runners can.

leaves

The leaf rosettes consist of up to five centimeters long, rather thick leaves that have a matt pale green color and are pinnate.

Blossoms and flowering period

From the flat rosettes of the leaves, the significantly higher flower stems grow in spring, on which there are many small, cup-shaped flowers. Depending on the variety, these can appear in a wide variety of colors. For example, there are white, yellow, purple, pink or deep red varieties. However, varieties with changing flower colors that can fade or darken over time are particularly interesting.

The main flowering time of the Saxifraga x arendsii hybrids falls in the months May to June, whereby some varieties can bloom significantly earlier if the weather is appropriate. After flowering, capsule fruits are formed.

Location and soil

The different Saxifraga arendsii hybrids have quite different demands on the location. Basically, almost all varieties thrive in the Penumbra to shade, although some varieties require more light than others. Basically, however, you can't go wrong with a bright but sunny location. Much more important is the soil, which has a high permeability and has to be fresh rather than dry. The perennial feels most comfortable in humus rich, nutrient-rich soils, which are particularly preferable because moss saxifrage is difficult to grow due to its often low height fertilize is. However, the plant also thrives very well in poor soil, but is then dependent on a regular supply of nutrients.

Plant moss saxifrage properly

Plant the moss saxifrage plants in the months between spring and autumn at intervals of 20 to 30 centimeters into the bed, whereby the recommended planting distance depends heavily on the selected variety is. It is therefore imperative that you follow the instructions on the plant label. Before planting, work ripe compost or well-rotted manure into the soil and submerge the root ball in a bucket of water before planting. In this way, the roots can soak up moisture again and then grow on more easily.

Specimens planted in spring do not bloom until the following year, which is why autumn planting is preferable for rapid bloom. The cushion-like growth also only sets in a few months later.

Pour moss saxophone

Most Saxifraga arendsii hybrids prefer fresh soil, which is why you should water regularly, especially in longer dry periods. Always water the plants from below, never over the leaves. The water can accumulate in the rosettes, which in turn leads to rot and fungal diseases. For the same reason, a permanently moist surface or even waterlogging must be avoided at all costs. During planting, it makes sense to cover the area with bark mulch, gravel, etc. ä. to mulchso that the soil does not dry out too quickly and you have to water less.

If the moss saxifrage leaves its leaves hanging, it usually needs water. Healthy plants recover quickly after watering and are not damaged.

Fertilize moss saxifrage properly

Basically, you only need to grow Saxifraga arendsii hybrids in very poor locations. fertilize in case of deficiency symptoms. To do this, spread some compost among the plants and work it lightly - and carefully so as not to damage the roots - into the soil.

Cut the moss saxifrage correctly

Regular pruning is not necessary, but dead leaf rosettes and faded stems should be removed promptly.

Propagate moss saxifrage

The various hybrids of the moss saxifrage can be easily reproduced either by dividing or by rooting cuttings. Since Saxifraga x arendsii only very rarely develops fruits and thus seeds, propagation via seeds is in principle possible, but is rarely used.

division

In any case, the plants should be dug up at intervals of two to three years, divided and separated from each other in a new location be planted - moss saxifrage has a habit of developing loose growth over time and thus closing holes in the upholstery receive. The regular division gives you the compact and dense growth. And that is how it works:

• Carefully dig up the plants.
• Gently shake off any clinging earth.
• Carefully tear or cut the plants together with the root ball.
• Cut away diseased parts of the plant and bald spots.
• Put the individual plants in a new location or in fresh substrate.
• Water the planting vigorously to encourage new root formation.

Cuttings

When propagating cuttings, take young shoots from the cushion edges in early summer, which you either take with you into the bed or first in a pot Potting soil plants. Some of these cuttings are already rooted, as moss saxifrage multiplies by itself. Incidentally, with the help of cuttings, bald spots can be covered very well by placing the plants on them. The cuttings grow well within a few weeks and close the gaps in the padding.

Overwinter

Moss saxifrage is very hardy and only needs light winter protection if it is freshly planted young plants or specimens cultivated in pots. In addition, freezing temperatures - i.e. low temperatures below zero without a protective blanket of snow - can also become a problem, which is why you should cover the plants with brushwood or leaves in the cases mentioned. Remove the cover in good time in spring so that the perennials can sprout again. However, watch out for late frosts and protect the plants from them if necessary.

Species and varieties

There are around 480 different species of saxifrage, some of which are difficult to distinguish from one another. That grows only about ten to 20 centimeters high Moss saxifrage (bot. Saxifraga x arendsii) is wonderfully suitable for planting rock gardens, but can also be settled in crevices or on dry stone walls. Here the low perennial shows its decorative flowers, depending on the species and variety in spring between March and April or in late summer between August and October. There is a large selection of varieties in different flower colors. For the ornamental and front garden, for example, these are very suitable:

• 'Carpet of flowers': up to 20 centimeters in height, carmine-pink flowers between March and April
• 'Bob Hawkens': up to 15 centimeters in height, pink flowers between May and June
• 'Sleeping Beauty': up to 15 centimeters in height, light red flowers between May and June
• 'Spring snow': up to 25 centimeters in height, pure white flowers between May and June
• 'Ingeborg': up to 15 centimeters in height, dark red flowers between May and June
• 'Peter Pan': Growth height up to 15 centimeters, carmine-red flowers between March and April
• 'Purple coat': Growth height up to 15 centimeters, purple flowers between April and May
• 'Rose dwarf': up to 20 centimeters in height, purple-pink flowers between April and May
• 'Snow carpet': up to 40 centimeters in height, pure white flowers between March and April
• 'White Pixie': Growth height up to 20 centimeters, white flowers between April and May

Moss saxifrage, Saxifraga bryoides

In addition, the species Saxifraga bryoides, which is native to the Pyrenees and other European mountains, is also known as the moss saxifrage. This perennial, which also forms cushion, is very similar to Saxifraga x arendsii, but usually remains smaller with heights of up to ten centimeters. This species also only blooms between July and August and therefore much later.

Alternatives / Similar types

Very similar to the moss saxifrage are also species that are often planted in gardens, such as the garden saxifrage (bot. Saxifraga cortusifolia) or the shrub saxifrage (bot. Saxifraga cotyledon). In contrast to the moss saxifrage, the garden saxifrage can also thrive in partially shaded to shady locations, and it only blooms in autumn between September and October. The shrub saxifrage, on the other hand, needs a sunny spot, but only blooms between June and July.
