Avoid overhead watering to prevent fungal diseases, and instead water directly at the base of the plant. During hot, dry periods, you may need to water more frequently, while in cooler, wetter months, you should reduce the frequency. Always ensure good drainage as rosemary does not tolerate waterlogged roots.
LightRosemary 'Miss Jessopp's Upright' thrives best in full sunlight, with at least 6 to 8 hours of direct sun each day.

Life cycleSalvia rosmarinus 'Miss Jessopp's Upright', commonly known as Rosemary, begins its life as a seed that germinates in warm soil with plenty of sunlight. Seedlings emerge and develop true leaves, establishing a small root system. As a perennial herb, it quickly enters a vegetative stage, where it grows woody stems and needle-like leaves, with the plant increasing in size and forming its characteristic upright habit. Rosemary blooms in late spring to summer, showing small, usually blue to purplish flowers that attract pollinators. Following pollination, flowers may develop into tiny seeds that can be dispersed for the next generation, although rosemary is often propagated through cuttings for consistent plant traits. The plant then typically enters a period of dormancy in colder months but remains evergreen, slowing down growth until warmer temperatures return.
PropogationPropogation time
Spring-Early Summer
Salvia rosmarinus 'Miss Jessopp's Upright', commonly known as upright rosemary, is most commonly propagated using semi-hardwood cuttings. The ideal time for taking cuttings and propagating this plant is during the late summer to early fall. To propagate by cuttings, select healthy, non-flowering stems around 4 to 6 inches long. Strip the leaves from the bottom two-thirds of the stem and dip the cut end in rooting hormone. Plant the cutting in a mix of sand and peat or a well-draining potting soil, ensuring that the leafless part of the stem is buried. Keep the soil moist but not waterlogged, and place the pot in a warm, bright location out of direct sunlight. Roots typically develop in a few weeks, after which the new rosemary plants can be gradually acclimatized to outdoor conditions before being planted in their final location.
