Dahlia Show at the Botanic Garden

We went to the South Coast Botanic Gardens today to see the Dahlia Society’s annual show. We try to attend every year, but missed it last year for some reason. Today, we were glad we didn’t miss this one. They outdid themselves from the last time we were here.

There were dahlias of nearly every size, color and variety. The colors were stunning. Hundreds on hundreds of beautiful flowers and arrangements. I took over 150 photos today and I wish I could show them all. The slideshow below is but a small sampling of the wonderful flowers we saw.

Move your mouse cursor over the images to stop the slideshow; move out to resume.

Sunflower Spirals

Damsel acquired some beautiful sunflowers yesterday for the table centerpiece vase. She snapped this close-up of the center of one of them. When I downloaded the picture, I couldn’t help but notice the natural symmetry of the Fibonacci spiral pattern that dominates the center of the flower.

From the center of the flower, the spirals propagate in both right and left hand patterns outward. The spirals are not only aesthetically pleasing, but mathematically perfect*, in my book. Click on the flower for a closer look at the spirals.

* Definition of the Fibonacci series:

F(0) = 0, F(1) = 1, F(n+2) = F(n + 1) + F(n)

Summer Mums

We went shopping for groceries this afternoon. When we got to the flower concession, I found these pretty mums in a pot. These remind me of the “whirligig” African daisy we see in the botanic gardens in the spring and summer months. Click on the image to enlarge.

Cutting Back the California Fan Palm

tree-trim.jpgLast weekend, I had the onerous task of trimming back an aggressive California Fan Palm in the back yard. I put this off hoping for a low marine overcast day to keep me cool while working. As luck would have it, the overcast burned off shortly after sunrise.

Anyhow, I got out the electric chain saw and started in on this beast. After having the chain jump off of the track once early on, I readjusted the tension and generated two green bins worth palm fronds.

The image is the before and after. Click to enlarge.

I mentioned that this is an aggressive tree. These start growing in cracks in the sidewalks, between ties in the local railroad tracks, out of the sides of other trees – places you would find hard to believe. In fact, most of the local gardeners and tree trimmers consider them as weeds.

Another ‘feature’ is the presence of extremely sharp spikes that line both sides of the frond stems. See this post from March 2007 (content warning – gross injury depicted).

The act of trimming this tree is only a prerequisite to taking it down. Damsel has asked me to get ALL of these out of the yard and I agree that it needs to happen.

Carrion Flower

starfish.jpgDamsel took this picture of one of my favorite plants. It’s called Stapelia Gigantea and is a cactus-like succulent native to the African continent. I like it, but not because it has pretty flowers, not because of lavish green stalks and certainly not because it smells good.

Every summer, the plant produces several pods that grow like great pointed balloons and then explode into five-pointed, hairy flowers that produce an aroma of rotting flesh. While flowers are in bloom, the flies flock to it and consequently keep out of the patio area. I like that about it – it’s sorta like a fly trap.

That’s Damsel’s hand lifting the drooping starfish up to be photographed. The plant can be seen at the left. Click on the image to enlarge.

Here’s more information about this exotic stinker that I lifted from UBC Botanical Garden:

As with many plants, Stapelia gigantea has a suite of common names. These include carrion flower, giant toad flower, Zulu giant, starfish flower and (in Australia) dead horse plant. Most of these are fairly descriptive – it does smell like carrion, it comes from Africa, it’s big, it resembles a starfish and it attracts flies like a dead horse. I haven’t been able to deduce the reason for toad flower, though (perhaps also because of the flies?).

You have probably guessed that this odd plant is pollinated by the blow-flies it attracts.

I should sneak in that Stapelia gigantea is considered an invasive plant in Hawaii and a weed in Australia.

Orange Echeveria Flowers

eschevaria-orange.jpgI’ve been trying out the new camera today (we didn’t do our usual Sunday shoot). I took a close-up of several flowers in the patio garden. This was the favorite one today.

I’m not sure of the exact name for this variety of echeveria, but the color and texture are very eye-appealing. We bought this echeveria at a succulent sale at the Botanic Garden and the label on the side of the pot says ‘ranunculus.’ I can assure you that this is not a ranunculus.

The Yellow Devil’s Tongue Flower

One of the most beautiful flowers in our collection of succulents (and all of the flowers are beautiful), is the Devil’s Tongue Barrel Cactus flower. These waxy, delicate, yellow flowers emerge from the most hostile-looking array of spikes and hooks that protect the flesh of this cactus. We don’t know if the flowers have any fragrance because who wants to put their nose close enough to tell?
