Golden Barrel Cacti – So Many Uses

Do you like cactus?

I find that even people who aren’t huge fans of cacti, tend to like make an exception for golden barrels (Echinocactus grusonii).  

I think one of the reasons for its popularity is because of its globular shape and yellow spines.

Another reason may be that golden barrel cacti are extremely versatile in the landscape.  Whether you prefer a contemporary landscape with golden barrels planted in neat, orderly rows or in a more natural grouping – they can be used both ways.

I like to place golden barrel cacti next to boulders, where their round shapes and sunny color provide great contrast.

These popular cacti are native to the desert Southwest and can be grown outdoors in zones 9 and above.  However, larger specimens have been known to handle temperatures in the teens.

In colder regions, they can be planted in containers and brought inside in winter.  

If you look closely at a golden barrel’s spines, you’ll notice how they criss-cross each other, forming an interesting geometric pattern.

You can probably guess one of the spines purposes – to provide protection from predators who may want to eat them.

However, there is another, somewhat surprising way that the spines help the cactus, which you read here:

“Why Do Cactus Have Spines?”

The care for golden barrels is quite simple.  They do best in well-drained, native desert soil in full sun to filtered shade.

Although they start out small, mature specimens can reach 3 feet tall and wide.  However, they can take years to reach that size, so they are often planted in much smaller areas and later replaced.

Now for the big question – how much water do they need?  Established golden barrels can get by with existing rainfall, but will grow faster and look their best with they recieve a deep watering once a month May through August.  The rest of the year, they should be fine with existing rainfall.

Earlier today, I mentioned on my azplantlady facebook page that I had seen golden barrel cacti growing in a very unusual place.

Well as promised, here is the answer:

I came across this cluster of golden barrel cacti growing in Michigan!

To be precise, they were located in a greenhouse at the Frederik Meijer Gardens in Grand Rapids, which I visited back in June.  I was looking forward to visiting these beautiful gardens and seeing examples of plants that grow in more temperate climates, so I was quite surprised to come across a plant from home.

So, even if you live in a climate that experiences frigid winter temperatures – you can grow golden barrels….inside.

How about you?  Do you have golden barrel cacti growing in your landscape?  Do you like seeing them in a more formal setting or a natural one such as when planted next to a boulder?
