| I was wondering where there was a zone 9b, Bootville? Venice? And hoping sonmeone would respond. I assume you mean the jacaranda acutifolia (http://www.floridata.com/ref/j/jaca_acu.cfm) Which is a zone 9-11. Baton Rouge as I recall is a high zone 8. I read elsewhere that mature trees do better with frost than younger trees.
Seems, if you can find a more mature tree or baby it through the first few years.... It might work. But then we may be getting ready to cycle through 20-30 years of colder winters. If you try the blue jacarda. And it works. Let me know. This tree, red sealing wax palms, travellers palms and royal poinciana are my dream trees. |
