Philadelphus coronarius
Sweet Mock Orange
Philadelphus coronarius
Philadelphus coronarius, commonly known as Sweet Mock Orange, is a deciduous shrub prized for its fragrant, creamy-white flowers that bloom in late spring to early summer. It's a relatively low-maintenance plant that can tolerate a range of soil conditions and is often used in hedges, borders, or as a standalone specimen. Its intense fragrance resembles that of orange blossoms, hence the common name.

Butterfly bushes can compete for resources if planted in close proximity, potentially hindering the Mock Orange's growth.

Boxelder maples are fast-growing and can quickly outcompete Mock Oranges for sunlight and nutrients.

Aphids

Aphids are small, sap-sucking insects that can cluster on new growth, causing distorted leaves and reduced vigor. They leave behind a sticky substance called honeydew which can attract ants and promote sooty mold growth.

Spider Mites

Spider mites are tiny pests that suck sap from leaves, causing stippling, yellowing, and webbing, especially during hot, dry weather. Severe infestations can weaken the plant.

Steps:

    • Take semi-hardwood cuttings in late spring or early summer.
    • Select stems that are healthy and about 4-6 inches long.
    • Remove the lower leaves, leaving a few at the top.
    • Dip the cut end in rooting hormone.
    • Plant the cutting in a well-draining potting mix.
    • Keep the soil moist and provide humidity by covering with a plastic bag or humidity dome.
    • Roots should develop in a few weeks. Transplant to individual pots once roots are established.
