Duranta (Sky Flower) Leaf Specks and Powder: Neem Oil Treatment

Potted Duranta with Black Specks and White Powder

4-month-old plant in West Palm Beach, FL. Morning shade, afternoon sun. Black round specks on upper leaves (brush off). White powder on undersides (washes off).

Recommendation

Spray with neem oil (organic, doesn't wash off, alters bug taste). Or local nursery spray. Specks not harmful; powder could be several things—same spray covers both. Neem preferred over contact sprays that wash off.
