Propagation of Selago thomsonii Rolfe var. whyteana (Rolfe) Brenan
Selago thomsonii Rolfe var. whyteana (Rolfe) Brenan, also called the Nightshade bluebush, is a rare shrub species that belongs to the family Goodeniaceae. This beautiful plant can grow up to 1-2 meters tall and 1.5-2 meters wide, with long slender leaves and small purple-blue flowers.
Propagation by Seeds
Propagation of Selago thomsonii is best done by seed, as the plant is challenging to root from cuttings. The seeds should be sown into a well-draining soil mix in late summer to autumn, as the plant is native to the southern hemisphere and will germinate best during this period. The soil should be moist but not waterlogged, and the pot should be placed in a warm and bright position
The seeds should take up to six weeks to germinate, and once they have sprouted, the seedlings should grow in a warm and bright location until they are large enough to transplant. After six months, they should be able to survive in the open ground.
Propagation by Cuttings
Although Selago thomsonii is challenging to root from cuttings, it is still possible to propagate the plant using this method. Cuttings should be taken from softwood growth in spring, and they should be around 4-6 cm in length. The leaves on the lower half of the cutting should be removed, and the stem's bottom should be dipped into a rooting hormone powder.
The cutting should then be planted into a pot filled with multipurpose compost, with the soil being kept moist until the roots have established. This can take several months, so it is best to be patient and avoid overwatering the plant. Once the roots have established, the plant can be transplanted into a larger pot or directly into the soil in a warm and bright location.
Overall, Selago thomsonii is a rare and beautiful shrub species that can be propagated by seed or cuttings. Although it can be a challenging plant to propagate, it is worth the effort due to its stunning appearance and unique characteristics.
