Check out Aloysia virgata, it's not massive but it's fragrance makes up for it

I have 2 and I love them. I've never had trouble with storm damage. My sister has one (helped her plant it) and it is beautiful. I highly recommend this tree. I'm in Tempe.

This tree is subject to salt burn in our alkaline soils and salty water. If you have flood irrigation you can keep them pretty happy, but the ones I've seen in granite landscaped areas or sprinkler irrigated lawns seem to be stressed.

Why not consider a better adapted tree like Desert Willow, Chitalpa or even the thornless Cascalote (Caesalpinia cacalaco)?

My Hong Kong Orchid trees are not planted in gravel or in the lawn and maybe they don't do that well in those locations, I don't know. Mine is on drip irrigation and I deep water periodically. Same for my sister's. All are planted next to a wall, in my back yard, and her side yard. I've not ever seen any sign of salt burn, etc., on the Hong Kong Orchid, though I've seen this commonly on the purple orchid tree.

I also grow cascalote and desert willow, and of course they do well here. However, I do like a tropical look in some areas of my yard, and Hong Kong Orchid trees fit that bill.

Again, I would recommend these trees under the right circumstances. I think they are too seldom planted here, and they are beautiful trees.

I planted a HK orchid as a 24" box about 5 years ago in a lawn area. Salt burn and chlorosis can be an issue but it hasn't affected the trees' growth. It is now over 20 feet tall and 15 feet wide and when it's in bloom which is twice a year, it's spectacular.

I Planted a HK TREE LAST MAY 2017 IT WAS 6FT HIGH IN A 24" BOX. BLOOMED UNTILL IN OF JUNE, BEGIN BLOOMING AGAIN IN DEC 2017 AND NOW IN FULL FLOWERS, ITS FAST GROWING AND BEAUTIFUL, EVERYONE LOVES AS I DO.
