The cranesbill hybrid "Rozanne" is one of the most vigorous and vigorous geranium species. It is a creeping perennial whose shoots can grow up to one and a half meters long. The numerous, very large, bright violet-blue flowers appear continuously between May and November. In contrast to other cranesbills, "Rozanne" cannot be propagated by seeds, only by division.
For propagation, the rootstock of Cranesbill Rozanne is divided in spring
Propagate "Rozanne" vegetatively
For most cranesbill species, the most effective way of propagating is by seed, with the plants very often self-seeding. hybrids, i.e. H. Crosses of different species, including "Rozanne", are mostly infertile. This means that propagation via seeds is not possible. Very often "Rozanne" does not even form fruit, let alone seeds. Propagation via cuttings is usually not very successful with this geranium variety. For this reason, the only option left is duplication by division.
Divide "Rozanne" in spring
The best time to divide is in spring, around April or May. To do this, proceed as follows:
- Carefully dig up the mother plant with a digging shovel.
- Avoid damaging roots as much as possible.
- Shake off the soil vigorously.
- Check the roots for any damage.
- Remove any short shoots.
- If these are already rooted, you can also plant them.
- Now divide the rootstock into several sections, depending on the size of the clump.
- Each section should have roots and several shoots.
Almost all cranesbills can be propagated by division
In addition to "Rozanne" and other hybrids, numerous other cranesbill species can also be propagated in the manner described. The various varieties of the Magnificent Cranesbill (Geranium x magnificum), a very vigorous hybrid with large, strong violet-blue flowers, can only be propagated by division. Vegetative propagation is also recommended for varieties that have been heavily refined by breeding, as these cannot usually be bred by sowing as a single variety.
tips
Some cranesbill species such as the rock cranesbill (Geranium macrorrhizum) form above-ground rhizomes from which you can obtain so-called rhizome cuttings. This type of propagation is often very successful.
