The cranesbill hybrid “Rozanne” is one of the particularly flowering 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, strong violet-blue flowers appear persistently between May and November. In contrast to other cranesbills, “Rozanne” cannot be propagated by seeds, but only by division.
How to propagate the cranesbill Rozanne?
The cranesbill hybrid “Rozanne” cannot be propagated by seeds, but by division in spring. To do this, the mother plant is dug up, soil is shaken off, the rhizome is divided and the sections with roots and shoots are planted.
Propagate “Rozanne” vegetatively
For most cranesbill species, the most effective way of propagation is by seed, whereby the plants often self-sow. Hybrid, i.e. H. Crosses of different species, including “Rozanne”, are usually infertile. This means that propagation via seeds is not possible. Very often “Rozanne” does not even produce fruit, let alone seeds. Propagation via cuttings is usually not very successful with this geranium variety. For this reason, the only option left is reproduction by division.
Share “Rozanne” in spring
The best time for division is spring, around April or May. Proceed as follows:
- Dig out the mother plant carefully with a digging shovel (€4.00 on Amazon).
- Avoid damaging roots if possible.
- Shake off the soil vigorously.
- Inspect the roots for any injuries.
- Remove all short shoots.
- If these are already rooted, you can plant them too.
- Now divide the rootstock into - depending on the size of the clump - several sections.
- 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 strong, violet-blue, large flowers, can only be propagated by division. Vegetative propagation is also recommended for varieties that have been heavily refined through breeding, as these generally cannot be bred by seed.
Tip
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.
