- Life cycle
Physocarpus opulifolius 'Diabolo', commonly known as Ninebark 'Diabolo', begins its life cycle as a dormant seed, which requires a period of cold stratification to germinate. Once germinated, the seedling emerges and develops into a young plant establishing its root system and producing the characteristic purple to burgundy leaves. As the shrub matures, it enters the vegetative growth stage, increasing in size and producing multiple stems. During the spring, Ninebark 'Diabolo' enters the reproductive stage, blooming with clusters of white to pinkish flowers that attract pollinators. After pollination, the flowers develop into small red fruits (follicles), which mature, dry, and release seeds to complete the reproductive cycle. Throughout its lifetime, Physocarpus opulifolius 'Diabolo' will undergo periods of dormancy during colder months, resuming growth each spring.
- Propogation
Propogation time
Spring-Early Summer
The Ninebark 'Diabolo' or Physocarpus opulifolius 'Diabolo' is commonly propagated by softwood cuttings taken in late spring or early summer. To propagate, select a healthy, young shoot and cut a 4 to 6-inch (approximately 10 to 15 cm) section just below a leaf node. Remove the leaves from the lower half of the cutting and dip the cut end in a rooting hormone powder to encourage root development. After preparing the cutting, plant it in a pot filled with a mix of peat and perlite, ensuring good contact between the cutting and the rooting medium. Keep the cutting in indirect light and maintain consistent moisture without saturating the soil. Roots typically develop within 4 to 8 weeks, after which the new plant can eventually be transplanted outdoors.
