First is this guy, Western Clematis, Clematis occidentalis. The first cool thing about it is its flowers, which have not petals, but has colorful sepals instead, sort of like a Blackbrush flower, only bigger and more elegant. The 2nd cool thing is that it’s a climbing vine, of which there are only a handful native to
Next up is this little fellow; I’ve been seeing it all over the place for weeks but just ID’d it. It’s Ballhead Waterleaf, Hydrophyllum capitatum. The 1st cool thing about is is that it’s greens and roots are edible, and were regularly collected and consumed by Indians, and later early settlers. (They supposedly require boiling, and no I haven’t tried it yet.) The 2nd cool thing is that this flower is a favorite pollen and nectar source for one of our native Osmia bee species, making this a perfect spot for a…
After emerging from her nest as an adult, a female Mason Orchard Bee has between 4 and 8 weeks to live. During this time, she has to mate, find a suitable hole for a nest, and lay roughly 8 eggs in each nest, each with its own compartment and food provisions to nourish the egg through its larval and pupal stages and into adulthood. And she typically does this for an average of 4 separate nests during her short life. (And I thought my summer was busy...)
While the honeybee travels repeatedly back and forth to the same type of flower to collect the same thing (pollen or nectar), the Mason Orchard bee visits multiple flower types during the same flight, collecting both pollen and nectar.
Our 3rd purple wildflower is really cool. It’s Low Larkspur or Nutall’s Larkspur, Delphinium nuttalianum. There are a number of Larkspur-type species. Their distinctive shape is caused by the top sepal, which juts back horizontally. The 1st cool thing about Low Larkspur- well I guess the 2nd, technically, since the shape itself is pretty cool- is that both the sepals and petals are wonderfully colorful, yet very different. The dark outer “petal-looking” leaves are the sepals; when you look “inside” the flower straight on, the real petals are visible- white with delicate purple streaks.
The next cool thing about the Low Larkspur is pollination. Early in the season, it’s most important pollinator is Hummingbirds. But by mid-summer, the Hummingbirds ignore it, and its most important late-season pollinator is queen bumblebees. The reason Hummingbirds only pay it mind early in the season is because in late Spring when the Hummingbirds arrive in breeding season, there aren’t a lot of nectar-rich flowers yet in bloom; the pickings are slim and Low Larkspur looks like a good use of time. But later in the summer, when all sorts of flowers are in bloom, Hummingbirds have a number of nectar-richer flowers to visit instead.
The 2nd- or I guess 4th, so much for consistency in this post- cool thing about Low Larkspur is pretty sinister- it’s poison. Not, apparently, to wild critters, but to livestock big-time. After locoweed, it’s the most poisonous thing to cattle on the Western range. Cattle find Low Larkspur, and several related species of Larkspur- highly palatable and they eat it readily. Unfortunately, all parts of the plant, and especially the seeds and recent growth, contain toxic alkaloids which, in heavy concentrations, are highly poisonous to them.
Nested Chemistry Tangent: My friend Rick, who is- as luck would have it- an organic chemistry professor, looked up the specific alkaloid at work in Low Larkspur. He didn't have a soft-copy diagram for me, but he says it's a monster molecule- multiple rings, tails, and probably 50+ atoms...
