Happy TreeTober! Today’s tree is the White thorn/Falcon’s claw Acacia, or Acacia polyacantha.

This tree is native to Africa and Asia. Surprisingly enough, ours was grown from a seed given to us by a botanical garden in Liège, Belgium. The sap of this tree can be used to make candy or adhesive. An extract of the roots is used to treat snake bites, and the strong smell of the roots can be used as a snake repellant.

This tree can be found in the thorn forest, across from the south lawn.

Thanks to our horticulture team, student interns, and volunteers for helping remove the weeds in the flower fields this past month. More sunflowers have grown, and bees have already rolled into the flower fields! Did you know that bees and sunflowers have a mutual relationship? Sunflowers provide a lot of pollen and nectar, which bees collect to create honey to feed their colonies. Bees provide sunflowers with the means to reproduce seeds by spreading pollen from sunflower to sunflower. This process is called pollination. They are just as hard-working as we are!

This tree cultivar originated in Placentia, California by George Hind in 1890. Due to its success, Orange County became one of the biggest walnut producers of the time. In the 1910’s it was affected heavily by disease, which greatly diminished the number of groves here in the OC.

This album popped up today and I thought ID share.

When you announced your closure I offered to help set up a fully electronic version of your Veggie Palooza - are you interested in doing this so the thousands of plants don’t go to waste?
Whereas I love all the close-ups of flowers and plants, do you have any wide-angle landscape photographs that we could use for backgrounds in Zoom meetings?
Any chance we will see a late spring bloom after the rain, and if May allows it?
I have an idea on how to do the sale virtually...

I can set up a simple online shopping cart / form where you can take orders and credit cards and then have pickers gather the orders and place the selected items on numbered trays for pickup. People drive up, verify their order number, grab and go.

No human to human contact and all payment done electronically only.

Let me know if you're interested.
