Broom Berries, Yeah, Right...


Day 350: "Well, that's bloody weird," I said aloud when I spotted a tight cluster of orangey-red berries on a sprangly plant. "I've never seen huckleberries do that before!" And then I took a closer look at the plant. It wasn't a huckleberry bush. It was Scotch Broom (Cytisus scoparius) which, as a legume, makes pea pods filled with little black seeds, not bunches of brilliant berries. "What the heck? Waitaminit, that's on a different stem." I followed the vine downward (and it was clearly a vine once I really started analyzing), and eventually arrived at a few sickly leaves about a foot from the ground. "Oh, dumb me!" I said, laughing at myself. "It's a freaking honeysuckle!" Sure enough, once I pushed the tangle of blackberry thorns away from the base, I could see where the honeysuckle vine (Lonicera ciliosa) had come up right beside the main stem of the Scotch Broom, and had taken advantage of the natural trellis. Satisfied that I had laid a major botanical mystery to rest, I moved on. Sometimes Ma likes to play jokes, and she got me good with this one.

Multicoloured Asian Ladybird, Harmonia Axyridis



Day 206: Harmonia axyridis has more common names than it has spot patterns, notably "Hallowe'en ladybug," "harlequin lady beetle," "multicoloured Asian ladybird" and assorted variations on those and other themes. It can appear in an entirely red or orange form, or it can have as many as 22 spots on its shell. The identifying feature which sorts it out in the field is its size. It is quite possibly the largest ladybug you'll see in the Pacific Northwest. A typical specimen (i.e., one which shows numerous distinctive markings) will have a white pronotum marked with black, as is the case here.

Introduced to the US to help control aphids and scale insects, these ladybirds frequently appear in large numbers during the spring and fall. Despite their abundance, they are not considered an invasive species, although anyone who's ever picked 38 of them off their shower walls before having a wash as I once did might disagree with that assessment.

The Business End



Day 204: The term isn't used much in today's vocabulary, but fifty years ago, you might have heard a shovel described as an "idiot stick," which is to say it has a blade on one end and an idiot on the other. In some regions, it applied to other manual tools as well, the principle being exactly the same regardless of what the "business end" might look like. I tend to think of weed-wrenches in much the same light. You have to be a few crackers short of a barrel to volunteer for a weed-wrenching work party, and I guess I qualify as prime crumb material. I spent the morning pulling Scotch broom with a weed wrench as part of a Nisqually Land Trust restoration project at Powell Creek near Yelm. The idea is simple: you set the jaws so that the stem of the offending weed is between them, then step on the tip of the tool and pull back on the lever which closes the jaws on the stalk. Once the stalk is pinched (sometimes not as easy as it sounds), you lean on the lever using the ground as your fulcrum, and if Archimedes is smiling, the earth moves as the roots are withdrawn. That's the theory, anyway. In practice, it's never that simple. The jaws slip, the stalk breaks, leaving the roots in the ground, thereby ensuring that you'll have a job again next spring. That said, we removed a lot of the nasty stuff, but it may be days before I can stand upright again.

Bloomin' Broom


Day 212: Invasive and pervasive, western Washington counties have all but given up on trying to eradicate Scotch Broom (Cytisus scoparius) from public lands. The best "weed warriors" can hope to do is control any further spread into areas not already infested. I won't claim it's easy to pull. Even small plants have a taproot extending to China, but with a weed wrench, it's possible to remove an established plant with a stem as thick as a child's wrist. Ideally, this should be done in the spring before the seed pods have had a chance to dry. Like many other weeds, Broom's pods burst explosively, discharging seeds over a radius of several yards.

I have to admit I think this pest is pretty when viewed en masse as a rolling sea of yellow, and there are a couple of colour variations less often seen, most commonly the red and yellow petal arrangement shown on the left. Rarely, you may find a plant with purplish-mahogany lower petals and creamy upper ones, but these are invariably smaller blossoms and are a hybrid. The scent arising from a broom-covered embankment is unmistakable; not quite sweet, a little pungent, pleasant to some and offensive to others. In the '60s and early '70s, dwarf hybrids were commonly planted along the freeways. Many people objected to the use of the plant in this manner, citing allergies to the pollen until eventually, the practice was stopped. Drivers on I-5 may still see examples of the dwarf varieties here and there.
