Propagation of Saxifraga fragosa Suksdorf ex Small var. leucandra Suksdorf
The plant Saxifraga fragosa Suksdorf ex Small var. leucandra Suksdorf can be propagated in several ways. Some of the most common propagation methods are:
Seed propagation
This plant generally produces a good amount of seeds that can be collected once they have ripened. The seeds are very small, so they must be sown on fine soil or seed starting mix and covered with a thin layer of sand. The containers should be kept moist and at a temperature range of 68-72°F until germination occurs. Once the seedlings are big enough, they can be transplanted into individual pots.
Division
This propagation method is suitable for mature plants that have formed several stems. The plant can be carefully uprooted, and the root ball can be divided into several sections. Each section should have some stems and roots. These sections can be planted in individual pots or directly into the garden. It's recommended to water them well after planting and to keep them in a shaded area for a couple of weeks until they have established.
Cuttings
Some varieties of Saxifraga fragosa Suksdorf ex Small var. leucandra Suksdorf can be propagated by taking stem cuttings. The cuttings should be around 3-4 inches long and have a couple of leaves. Remove the lower leaves and dip the cuttings' base into rooting hormone. Plant them in a mix of perlite and sand and keep them moist. Cover them with a clear plastic bag or a cloche to maintain humidity. Once the roots have formed, the cuttings can be transplanted into individual pots or into the garden.
