How to keep Polemonium Californicum.
Pruning
Polemonium is a plant known for its delicate blue flowers and finely divided leaves. To keep it healthy and attractive, regular pruning in early spring is essential. This involves removing dead stems and spent flowers, which encourages bushier growth and prolongs blooming. Pruning also helps improve air circulation, reduces the risk of disease, and maintains the plant's appealing shape.
