But they wouldn't grow back if they got hit by hard freezes & they would never grow big enough between freezes to set seed...

Strange how jacarandas struggle, yet CIDP, eucalyptus and acacia does well, and sets seed.

Dan Gill knows what will work in NOLA. He is well respected. You just don't see any large ones in NOLA. Sooner or later they get killed back. Just isn't worth it.

I don't know how well they grow over there, but somewhere like New Orleans has only only dropped to -6C in the last 10 years.. Even if - 6C did kill them, all the other nine years only had three years below freezing, so I think it would be well worth growing them as growth would be rapid.

True, places in the nc outer Banks here should try them, especially nags head and Cape hatteras. Zone 9a climates. Cape Hatteras has a higher yearly min temp than savannah.

So none of you believe the garden editor in New Orleans? Trust me if people could grow them there they would be all over the city. People have known about them for decades. Trust Dan Gill, he knows more than the folks on this forum about what can grow in New Orleans.

Hatters averages 1 ice day per year and got 3 in 2010 and 2 in 2014. Right there you are talking severe damage due to number of hours below freezing.

I do, but it's so warm there, that they would be worth growing even if just for a few years. I haven't paid a lot of attention to Jacarandas here (apart from flowering), but I would think they grow at the same rate as Albizzias - 20 ft in 3-5 years and flowering in the first year.

Some goes for citrus -modern cultivars are such fast producers, that they will be fruiting in the first year. It doesn't matter if they die after five years.

I think Jacaranda generally need frost free climates, large mature trees can take the odd dip to below freezing temperatures, as low as -6C, but they are essentially a subtropical tree... They also seem to take lower temperatures better in dry winter climates, if the winters are wet then your winters need to be mild & have fairly warm daytime highs too. This I think is why they wont grow in the UK, even in mild areas...

New Orleans is a micro-climate by the lake; Houston can build up into a giant megapolis, which creates UHI to keep the jacarandas warm.



Both New Orleans and Houston were frostless this past winter, and have many areas that remain frostless many winters. Jacarandas will survive.
