Acacia

When we moved into our house, there was an acacia in the backyard. Unfortunately, it did not survive. I have wanted to replace it for 20 years. Last year a friend gave me a start, it was a volunteer of one of his acacias. It did not survive. I took a cutting from one of his acacias, it was doing well, then suddenly died. Apparently, I was doing something wrong.

When I went to the San Luis Botanical Garden sale, I purchased an Acacia iteaphylla. It is a beautiful plant. Similar, but not the same as the original acacia.

Acacia in Courtyard

Monday when I was walking from the Hoover Herbarium to my car, I noticed a small acacia at the corner of the parking lot.

It may be Acacia podalyriifolia. It had a slew of seed pods, some already empty. With the help of Peggy, a fellow Herbarium volunteer, we snagged a handful of pods and I brought them home.

I researched how best to have planting success and every source seemed to consistently recommend placing the seeds in a container and to pour nearly boiling water over them. Then allowing the seeds to soak overnight.

I placed the remaining seeds in an envelope and may use the seed pods in a piece.

After a night of soaking there is a huge difference in the size of the seeds.

I planted the soaked seeds in a nine cell, in cactus mix. Placed the nine cell in the greenhouse. Now, I wait.

Update July 13

In 8 of the 9 cells there are sprouts.

Update September 2
The extreme heat yesterday took a tole on the 4 remaining Acacia seedlings. The temperature was 106º which is unusual for the California Central Coast.

Acacia Seedlings

Only 4 seedlings survived before the extreme heat. One of the seedlings may not make it. It is time to transplant the remaining seedlings into at least 4″ pots.
