Arabian Lilac

Vitex trifolia ‘Purpurea’ is an interesting small tree that could be used more often in the Phoenix area.

Drought tolerant and fast growing, the arabian lilac looks nice in a wide range of situations. It has white bark and noticeably purple undersides to light green leaves. The leaves smell peppery when crushed. The visual effect is very pleasant when they can be viewed up close like in a courtyard or next to a sitting area.

Arabian lilac is not messy except for a few dropped leaves as new foliage grows in. It’s not as deciduous as its cousin the vitex tree. Mine kept all its leaves all winter. It also tolerated being in a pot in the yard that didn’t get water as often as the flowerpots. It was totally fine drying out.

The arabian lilac can handle sun for most of the day. It does better with afternoon shade to protect it from burning. It’s also relatively frost tolerant.

I think this plant is becoming fashionable in the valley, because I’m seeing it more often in the nurseries. I’ve only seen one example of arabian lilac established in the landscaping. One or two of my wholesale nurseries sell it. I have a feeling we’re going to be seeing more of this plant as tastes change and different plants go in and out of vogue.

I recommend planting this tree somewhere with a little space to stretch out, while still being a protected spot where it can be appreciated up close. This tree won’t get as big as it does in California and other moderate areas.
