Chollas in bloom, and other early summer treats

[Bee in cholla blossom] We have three or four cholla cacti on our property. Impressive, pretty cacti, but we were disappointed last year that they never bloomed. They looked like they were forming buds ... and then one day the buds were gone. We thought maybe some animal ate them before the flowers had a chance to open.

Not this year! All of our chollas have gone crazy, with the early rain followed by hot weather. Last week we thought they were spectacular, but they just kept getting better and better. In the heat of the day, it's a bee party: they're aswarm with at least three species of bees and wasps (I don't know enough about bees to identify them, but I can tell they're different from one another) plus some tiny gnat-like insects.

I wrote a few weeks ago about the piñons bursting with cones. What I didn't realize was that these little red-brown cones are all the male, pollen-bearing cones. The ones that bear the seeds, apparently, are the larger bright green cones, and we don't have many of those. But maybe they're just small now, and there will be more later. Keeping fingers crossed. The tall spikes of new growth are called "candles" and there are lots of those, so I guess the trees are happy.

[Desert willow in bloom] Other plants besides cacti are blooming. Last fall we planted a desert willow from a local native plant nursery. The desert willow isn't actually native to White Rock -- we're around the upper end of its elevation range -- but we missed the Mojave desert willow we'd planted back in San Jose, and wanted to try one of the Southwest varieties here. Apparently they're all the same species, Chilopsis linearis.

But we didn't expect the flowers to be so showy! A couple of blossoms just opened today for the first time, and they're as beautiful as any of the cultivated flowers in the garden. I think that means our willow is a 'Rio Salado' type.

Not all the growing plants are good. We've been keeping ourselves busy pulling up tumbleweed (Russian thistle) and stickseed while they're young, trying to prevent them from seeding. But more on that in a separate post.

As I write this, a bluebird is performing short aerobatic flights outside the window. Curiously, it's usually the female doing the showy flying; there's a male out there too, balancing himself on a piñon candle, but he doesn't seem to feel the need to show off. Is the female catching flies, showing off for the male, or just enjoying herself? I don't know, but I'm happy to have bluebirds around. Still no definite sign of whether anyone's nesting in our bluebird box. We have ash-throated flycatchers paired up nearby too, and I'm told they use bluebird boxes more than the bluebirds do. They're both beautiful birds, and welcome here.

Dinosaur Eggs, Collared Doves and Wildflowers

[Dinosaur egg (okay, not really)] Happy Easter! In keeping with the season, here's a dinosaur egg I spotted on a recent hike.

Okay, or maybe it's just a vaguely egg-shaped rock. But there's been a lot going on this spring now that the weather is turning.

[Eurasian Collared Dove] First, we seem to have Eurasian collared doves nesting somewhere near our house. There's a dove up on the power pole, cooing, most of the day. I know I've heard lots of reports of collared doves around the south bay in past years, particularly down around Morgan Hill, but this is the first time I'd seen more than a glimpse of them here at home in San Jose. It's fun to see new species, though I hope these European interlopers don't push out the native mourning doves entirely.

[Shooting star] In addition, the wildflowers have been great out on the trails, especially around the south end of Windy Hill OSP and Coal Mine Ridge. A hike up there last week revealed nearly every wildflower on my wildflower page that could be in flower now -- California poppy, wild cucumber (intriguingly also called manroot), giant trillium, hound's tongue, milkmaids, the most impressive profusion of Indian warrior I've seen, blue larkspur, miner's lettuce, Sierra suncup, vetch (it's pretty despite the unfortunate name), red maid, wild radish, wood sorrel, broom, and my favorite, shooting star.
[Indian warrior and hound's tongue blooming  in Coal Mine Ridge] Dave had to keep waiting for me while I argued with the camera over macro focus distances. So if you like wildflowers, get out there and take a look!

Bay Area Wildflowers

Spring is in full swing, and all around the bay area the parks are ablaze with the colors of wildflowers -- blues and lavenders at Alum Rock, blues and yellows at Rancho San Antonio and oranges at Arastradero.

I've been shooting photos of wildflowers for years, always intending to collect them into a web page -- for my own reference (I always forget which wildflowers are which) as much as anyone else's.

At the same time, I've been gradually working on finding better ways of displaying photos on gallery pages. Most of my old pages use tables, which work fine in all browsers but don't scale very well with page size -- 4 images across may look fine in an 800 pixel wide window but look pretty silly at 1600 pixels. After playing with various CSS-based ideas for showing images and captions, I finally found the answer ("display: inline-block" is the key) on this CSS gallery demo. I adapted it for my site and wrote some PHP glue to generate the pages, and here's the result: Bay Area Wildflowers.

Update: Isn't it always the case? Just when you think you're done with something, you find out there's more to do. I wrote the preceding a week ago and then didn't manage to post it before leaving for a desert trip. And the desert was blooming! So here I am, ba-wildflowers site barely made public, newly back from the Mojave with a disk full of desert wildflower photos that aren't from the bay area. Looks like the "Bay Area Wildflowers" site needs to expand to a wider area ...
