"Paenoyflorus" is a variety of rose of Sharon (Hybiscus syriacus) that blooms in double, pale pink flowers from mid to late summer. It thrives in full to part sun and grows to a height of 12 feet with an 8-foot spread. Paenoyflorus is a deciduous shrub with yellow foliage in the fall. It is hardy to USDA zones 5 to 8.
Choose a location in which to plant the Paenoyflorus. An area that receives morning sun and afternoon shade is ideal.
Dig a planting hole for the Paenoyflorus. It should be the same depth as the nursery pot in which it is growing, and three times as wide. Lightly scrape the inside walls of the hole with a garden fork to allow the plant's roots to easily penetrate the soil.
Lay the nursery pot on its side and slide out the Paenoyflorus. Place the rootball on the bottom of the hole and fill the hole with soil.
Water the plant generously, until the soil is saturated, and water every other day until the Paenoyflorus is established. You will know this has occurred when the plant has new growth.
Place a 3-inch layer of mulch on the soil at the base of the plant and spread it in a 1-foot radius around it. Don't allow the mulch to touch the plant.
