Back in March, I bought a baby Jacaranda tree from Ebay. Well, they claimed it was a Jacaranda. Just recently I discovered Silk Trees which look remarkably like the Jacaranda. Everywhere I read, articles said the best way to tell them apart is by their flowers. Well either tree won't flower until a few years old. So is there any other way I can distinguish between the two? Is what I purchased a Jacaranda or a Silk Tree...or even something else? Here's some helpful info which may help identification:

  1. I purchased the tree as a tiny little sapling for $10 on Ebay.
  2. It was not bare root nor was it grafted. Def grown from seed.
  3. The seller was growing them in Florida.
  4. I live in Southern Texas.
  5. This tree has thrived in my clay soil with only watering once a week.
  6. Just came out of a drought too so the tree had no real rain water.
  7. The tree grew from about 1 inch tall to over 5 feet in about 6 months!
  8. Has one main trunk, though started sprouting a secondary one at ground level

  • My mother had a silk tree, but hers was more umbrella shaped, these have fronds all the way down. – user21470 Apr 28 '18 at 17:17

I have a jacaranda, also not flowering yet, which I know to be a jacaranda because it was also planted from a seed. It seems to be pretty easy to sprout these jacaranda seeds, so I would be inclined to believe your e-Bay seller for that reason alone. But also your tree looks just like my J. tree: trunk-dots, fluffy leaves, branches, fast growing, everything.

But. . . Now that you point out the similarity between silk tree (i.e. Albizia julibrissin or "mimosa tree"?) leaves and those of Jacaranda, boy they do look alike, even though not closely related at all. However, here is a "frond" off of my treejacaranda leaflets

The little "branchlets" (don't know what they're really called) have a single leaflet sticking out at the very tip, and notice the deep groove down the center of each leaflet. Just like in your photos. My end-leaflet looks a little longer than yours though.

I don't have an Albizia silk tree handy, but checking the internet, it looks like they don't have a leaflet at the very tips of the branchlets. So they do look a tiny bit different from the jacaranda.

So I think it truly is what it claims to be - Jacaranda.

  • I think you are right - the presence of terminal leaflets points to Jacaranda and not Albizia. For those that have something similar looking and want an ID, it is worth noting that a number of Acacia species are also very similar in appearance. – George of all trades Nov 30 '18 at 8:33
  • Paradise tree (Simarouba glauca) is another near match: en.wikipedia.org/wiki/Simarouba_glauca There are quite a few compound leaf trees like this, even Locusts. Sooner or later the flowers will tell the story. – Wayfaring Stranger Nov 30 '18 at 19:06
