Choisya x Dewitteana ‘Aztec Pearl’, Mexican Mock Orange: The Most Heavenly Fragrance

Aztec Pearl Choisya x dewitteana ‘Aztec Pearl’ or Mexican mock orange is an excellent evergreen shrub with a dense, rounded growth habit, and handsome, elongated glossy green leaves.  Leaves are palmately compound with 4 or 5 dark, narrow leaflets with smooth margins.  This shrub can be grown in full sun or shade, and is drought tolerant.  Aztec Pearl produces a very fragrant, nicely scented, white star-shaped flower which flowers in abundance on the plant between April and May.

The biggest threat to your choisya”Aztec Pearl” or Mexican orange blossom is damage from winter frosts and hard freezes. The best way to repair the shrub after a freeze is to prune out all the frost damaged wood, but you should wait until spring and the danger of frost has passed. Pruning too early in the season will only stimulate new growth. New growth in winter leaves the plant vulnerable to future frosts. Though this plant can easily be damaged, “Aztec Pearl” or Mexican orange blossom is hardy at the root level.  It can die all the way down to the ground and come back in the spring.  The shrub is best grown in a sheltered spot of the garden.

How To Make Choisya Thrive

Grow in well-drained soil in a sheltered position in full sun for best results.

    • Choisya ternate is the most common, Choisya x dewitteana is not seen quite as often. I think both the leaves and the flowers are more fragrant for x dewitteana ‘Aztec Pearl’, and my personal experience is it is a little more robust.

  2. Pretty stuff. I didn’t know there was a domestic species. We have lots of wild Philadelphus lewisii around us here.
