CHOISYA X DEWITTEANA 'AZTEC PEARL'

Choisya x dewitteana 'Aztec Pearl' is a popular hardy, glossy-evergreen shrub as well as being a remarkable hybrid between Choisya arizonica and Choisya ternata. It is the first inter-specific hybrid to be produced from the Choisya genus and was raised by plant propagator Peter More in 1982 at Hillier nurseries.

It is a small, elegant specimen with aromatic foliage and an open rounded habit. Depending on conditions you can expect Choisya 'Aztec Pearl' to reach a height and spread of between 1.5 and 2.5 metres. Each leaf is divided into 3-5 slender, bright-green leaflets and smell of rue when bruised or cut. 

The blooms are sweetly fragrant like its parent Choisya ternata, but are larger in size at approximately 3 cm wide. Each flower is pink-flushed in bud but opens up to reveal a pure white face although the back of the flower remains a flushed-pink. The blooms appear in abundance in May and then again in late summer in clusters produced in the leaf axils.

Frost damage can be an issue in colder, northern European climates, so it is best grown against a south-facing wall.

Choisya 'Aztec Pearl' will thrive in any well-drained garden soil, preferably in a position that receives full sun for most of the day. Be that as it may it will also tolerate partial shade.

No regular pruning is necessary, but shorten and thin out straggly shoots immediately after the main flowering period in May.

Choisya 'Aztec Pearl' received its Award of Merit from the Royal Horticultural Society in 1990.
