The South African Garden at the UC Santa Cruz Arboretum and Botanic Garden

We're back in Santa Cruz, California, at the University's Arboretum and Botanic Garden—Andrew and I visited last January. After touring the Australian garden, we've now wandered into the South African Garden.

Leucadendron argenteum, the silver tree.

I've seen several of these gems in other Botanic Gardens, as well as a few private gardens, but I've never seen any as large as the ones I saw growing here in Santa Cruz. They were AMAZING!

Of course really they're spectacular no matter the size.

Okay, let's admire some Protea flowers (with a few Leucadendron mixed in)...

Protea 'Red Ice'


Protea magnifica 'Empress'

Thamnochortus insignis, a species of grass-like restio of the family Restionaceae. This one is female (so said the signage).


Protea neriifolia 'Late Mink'

Leucadendron salignum 'Winter Red'

Protea longifolia—pink (long-leaf sugarbush).


Leucadendron 'Inca Gold'




Protea cynaroides, King Protea.

As I mentioned in Monday's post, this garden is a little wild and natural, labeling was sometimes a little hard to find, so I can't tell you the names of many plants.

No ID restio

Leucadendron salignum 'Red Gem' 

No ID Protea

No ID Protea

Phylica pubescens


Protea magnifica 'Empress'


Puya berteroniana—which were in the South African Garden, but are actually native to the Andes Mountains in Chile


Leucospermum glabrum 'Helderfontein'

Into the South African Succulents section now, where we finally saw blooming aloes!

Aloe cryptopoda (Geelaalwyn) 


No ID Aloe

Euphorbia enopla

Another tall Leucadendron argenteum.

Protea obtusifolia (limestone sugarbush)

No ID Leucadendron

No ID Leucadendron


Protea 'Susara'

Ending with a Leucadendron argenteum close-up, so much beauty! Come back on Friday for the final post from this series.

The Bit at the End
Want to grow some of these plants in your own garden (conditions willing)? I was going to share a link to the shopping page on Norrie's Gift and Garden Shop at the UC Santa Cruz Arboretum & Botanic Garden website (I guess I just did), but they don't ship! Instead visit Troy McGregor's nursery Waltzing Matilija, where there are South African plants available, Australian plants, and just a whole bunch of cool things.

  1. This garden is delicious! I truly lost my mind when I saw those huge Leucadendron argenteum in person. They were so liquid metal, I didn't even recognize them for what they were. I had to be told, those are your beloved silver trees. Embarrassing. I can see that I need to visit in January, great photos btw. Troy is the best, I second your recommendation.

  2. Those Leucadendron argenteum trees are mind blowing!
    I adored them at the southern tip of England, at 8" tall, but this is ridiculous.
    So many cool plants from the other side of the world; Phylica pubescens is one I'm sure I saw on your blog before. Whether on your wish list or something you tried to grow, I can't remember. It looks soft and sweet, nothing like Euphorbia enopla: stylish and dangerous, perfect for your garden theme.
