Fouquieria fasciculata

Comes from the dry tropical forest habitats to warm deserts in Mexico.

Is said to grow only on steep slopes and canyons in the Metztitlán area of Hidalgo west to adjacent Querétaro.

Has a massive, fat trunk that tapers into spiny branches.

I have had this plant for more than 25 years and I can't see any size difference in that fat trunk. I have cut back some of the branches.

I got it from a small road side plant place some where on our way to Deming New Mexico, or was it on our way back.  I can't remember.

It's been in the ground for the last 15 or so years. It was not flowered in all that time.

When it was planted in was in full sun, not any more as some trees have  grown up so now it's in part shade most of the day.
I know it should be move to get more sun but where?
 

Fouquieria fasciculata

I am not 100% sure if this is Fouquieria fasciculata. But that's what I'm calling it. If anyone know for sure let me know.

Had this plant for about 30 or 35 years. I pick it up on a trip down to New Mexico. I don't remember where.

I lived in Illinois back then and when we moved to Florida it came with us.

I planted it in the ground maybe 15 years ago and don't think it was got any larger, as far as the caudex. The thin branches have grown and I some times cut them back a little. 

In the back ground  you can see a few Jatropha podagrica leaves that re-seeded them self's around the yard.

I don't know if it flowers, it might but I don't look at it that much.
 It is planted in the shade unfortunately. It wasn't in the shade then it was planted.

The caudex is about 8 x 8.
