PHILADELPHUS

This genus of 60 species is a member of the Hydrangeaceae/Philadelphaceae family and is made up of deciduous shrubs from the temperate regions of East Asia, the Himalayas, the Caucasus, and Central and North America. The plants generally have peeling bark and light green roughly elliptical leaves that are smooth; in some species, the leaves are slightly hairy on the undersides. They flower in spring and summer, mostly bearing 4-petalled white or cream flowers that grow in loose clusters at the end of the leaft stem. Blooms can be single, semi-double, or double. The scent of the flower is very similar to that of orange blossom, hence the common name of mock orange. Philadelphus lewisii is the state flower of Idaho.


CULTIVATION


Philadelphus plants are easily grown in full sun, partial shade, or in deciduous open woodland in moist well-drained soil. Planting in full sun will increase the number of flowers,. Propagate from softwood cuttings taken in summer or hardwood cuttings in autumn and winter.


Top Tip


The delicious fragrance of Philadelphus flowers can be enjoyed indoors. Simply float fresh-cut flowerheads in a shallow bowl filled with water.
