  • water dropWater

    For the Mock Orange, it's important to maintain moist but not waterlogged soil, especially during its blooming period and the first few years after planting to establish the root system. In general, water the plant deeply once a week with about 1-2 gallons per watering session, depending on the local climate and soil drainage. During hot, dry spells, you may need to water more frequently to prevent the soil from drying out completely. Reduce watering in the winter when the plant is dormant, ensuring the soil doesn't become completely dry.

  • sunLight

    The Mock Orange thrives in a location that receives full sun to partial shade. The ideal spot would allow it access to at least four to six hours of direct sunlight daily. If you're planting it in a particularly hot climate, giving it some afternoon shade will help protect it from the most intense sun.

    Mock Orange plants are quite hardy and can withstand a range of temperatures but perform best when grown in the USDA hardiness zones 4 through 8. They can survive minimum temperatures down to about -30°F and are comfortable up to 90°F. The ideal temperature range for optimal growth is between 60°F and 75°F.

    Prune the Mock Orange immediately after it finishes blooming, usually in late spring or early summer, to maintain its shape and size and to encourage the growth of new wood, which will bear flowers the following year. Remove any old or dead wood, and thin out crowded branches to improve air circulation. Since the plant blooms on the prior year's growth, timely pruning is important to not remove the next year's blooms.

  • circleLife cycle

    The Mock Orange 'Dame Blanche' begins its life cycle when a seed germinates in spring, usually after a period of cold stratification which breaks seed dormancy. It then develops into a seedling, establishing a root system and sprouting its first leaves. As it matures into a young plant, the Mock Orange 'Dame Blanche' develops a woody stem and foliage, entering the vegetative growth phase where it focuses on gaining size and strength. After a few years, the plant reaches maturity and starts the reproductive phase, characterized by the production of fragrant, white flowers in late spring or early summer, which are pollinated by insects. Following pollination, it produces small fruit that contains seeds, completing the reproductive cycle. Over time, the plant may undergo periods of dormancy during colder months, shedding leaves if deciduous, and then resuming growth as the climate warms.

    • Propogation time

      Late winter to early spring

    • Propogation: The Philadelphus 'Dame Blanche', commonly known as Mock Orange, is typically propagated during late winter or early spring before new growth begins. The most popular method is softwood cuttings, which involves taking a 4 to 6-inch-long (10 to 15 cm) cutting from a healthy, non-flowering stem. The lower leaves are removed, and the cut end can be dipped in rooting hormone to encourage root development. The cutting is then planted in a pot with well-drained soil, ensuring at least two sets of leaves are above the soil surface. The pot should be placed in a warm, bright area but not in direct sunlight, and the soil should be kept moist but not waterlogged. Roots generally develop within a few weeks, after which the new plant can be gradually acclimatized to outdoor conditions before transplanting into the garden.
