These deciduous shrubs are the real deal when it comes to scent. Like the orange blossoms they resemble (they aren’t relatives), these flowers have a lovely fragrance. In fact, that is the most common reason they are planted. However, not all 40 species have the signature scent, so shop while they are in bloom so you can smell them.
Mock Orange Care Must-Knows
Mock orange shrubs don't require much special care. Plant in well-drained soil, preferably amended with loam and organic matter. They prefer evenly moist soil, especially during summer. They will not tolerate wet or poorly drained soil. For the most impressive blooms and fragrance, plant mock oranges in full sun.
Though it is not necessary to prune mock orange, trimming them controls their somewhat wild appearance. Pruning should be done immediately after the plant flowers. To maintain the size of your shrub, cut to about a third the height each spring. This encourages branching, too. As plants age, some of the mature woody stems can become less productive and unsightly. These can be cut back to the base to encourage new growth, improve air circulation, and let in sunlight.
