Propagation of Scrophularia californica var. desertorum
Scrophularia californica var. desertorum can be propagated either by seeds or cuttings. In general, propagation by cuttings is faster, while propagation by seeds is more reliable and ensures genetic diversity.
Propagation by seeds
In order to propagate Scrophularia californica var. desertorum by seeds, it is necessary to collect the seeds from mature plants. The seeds are usually ready to be collected in the fall, when the flowers start to dry out and the capsules become brownish. The seeds should be stored in a paper envelope or paper bag in a dry and cool place until they are ready to be sown.
The best time to sow the seeds is in the early spring, after the danger of frost has passed. The seeds should be sown in well-draining soil that has been lightly tilled and supplemented with compost. The seeds should not be buried too deeply, only about 1/8 inch into the soil. After sowing, the soil should be kept moist but not water-logged. Germination usually occurs within 1-2 weeks.
Propagation by cuttings
To propagate Scrophularia californica var. desertorum by cuttings, it is necessary to take stem cuttings from mature plants. The best time to take cuttings is in the spring or summer, when the plants are actively growing.
The cuttings should be taken from the upper part of the plant, approximately 4-6 inches in length. The leaves from the lower part of the cutting should be removed, and the cutting should be dipped in a rooting hormone before being planted in a well-draining soil mix. The soil should be kept moist, but not overly wet.
It is important to keep the cuttings in a warm and humid environment until they have established roots, which usually takes about 4-6 weeks. After the roots have developed, the plants can be transplanted into individual pots or directly into the ground.
