Pruning
The Dark Red Lousewort does not require a lot of maintenance in the form of pruning. However, it is beneficial to remove the spent flowers because it encourages new growth and blooming. If you notice dead or damaged leaves, you can trim them off to promote the overall aesthetics of the plant.
Propagation of Pedicularis atrosanguinea Pennell & J.W. Thompson
Pedicularis atrosanguinea Pennell & J.W. Thompson, commonly known as Dark Red Lousewort, can be propagated through two methods: seeds and stem cuttings.
Propagation by Seeds
The seeds of Pedicularis atrosanguinea Pennell & J.W. Thompson can be collected from the plant when the seed capsules turn brown and start to open. The collected seeds can be sown in the fall or early spring in a well-draining soil mix. The seeds require a period of cold stratification to aid germination. This can be done by storing the seeds in a plastic bag with a small amount of moist sand in a refrigerator for four weeks before planting. The seeds germinate in about 2 to 4 weeks after sowing.
Propagation by Stem Cuttings
Stem cuttings are an easy way to propagate Pedicularis atrosanguinea Pennell & J.W. Thompson. The cuttings should be taken in late spring from the upper part of the stem, just below the flowering top. The stem should be cut into 3-4 inch long pieces and stripped of its lower leaves, leaving only the top 2-3 leaves. The cuttings should be dipped in rooting hormone powder and planted in a well-draining soil mix. The cuttings should be kept in a humid environment with bright, indirect light until rooting occurs, which takes about 4-6 weeks. Once the cuttings have rooted, they can be transplanted into individual pots.
