Flowers going up and coming down Leave a comment

April 03, 2023

The first hummingbird appeared last weekend, zooming under the dangling red flowers of soap aloes. No surprise there. Those aloes put out quite the welcome mat for hummers.

The spiderwort has had a good run — here’s a volunteer by the covered porch, looking pretty — but the mild days of spring are rapidly drawing to an end. We’ve already had a 90-degree day or two, and more are expected today and tomorrow. That means ratty, gone-to-seed spiderwort, so I’ll be getting out the pruners and cutting them down this week.

Spuria iris are starting to flower, and according to my records, they’re about a month early. Wow!

I gave the ‘Winter Gem’ boxwoods a haircut last week with my battery-powered hedge trimmers. I’ve learned a new trick for doing this chore: spread a couple of old sheets around the base of the shrub before trimming. Afterward, gather the trimmed leaves in the sheets and dump them into the yard waste bin. No more yellowing leaves scattered on the ground!

The next day, as I reached across a boxwood to pluck a missed leaf, I sucked in my breath and yanked back my hand — that involuntary “zero at the bone” reaction. It was just a harmless rat snake stretched across the boxwood ball, resting there. I suspect it was hunting birds. A pair of titmice are raising chicks in the owl box on the deck post high above. I hope they stay safe, but I didn’t intervene.

I did intervene on something else. Last week I noticed a change in the leaf pattern at the top of the big Yucca rostrata. Was it going to bloom after all these years, I wondered?

Sure enough, a view from the deck revealed a bloom spike rising from the top. An exciting moment, especially because yuccas, unlike agaves, don’t die after they flower. But then I remembered that I treat my big, valuable yuccas and agaves annually with a systemic drench to keep them safe from the agave snout-nosed weevil. Systemic insecticides are taken up by the roots and stay in the system of a plant for a year. That means that when the flowers open and pollinators like bees or moths find them, they would be poisoned. That’s a big nope. So I used a pole saw to cut off the bloom spike.

I’m sorry not to be able to enjoy the drama and beauty of the yucca’s flowering. But I would feel terrible about harming pollinators that were drawn to it. Removing it was the responsible thing to do.

I’m unwilling to take a chance on losing my big yuccas and agaves to the weevil, so I treat them — carefully and slowly, avoiding runoff onto other plants. And then I must take care not to let them flower. That way, only pests that chew into the plants are affected.

In the night garden, palm fronds add fringey silhouettes…

…and an ‘Opal’ agave’s yellow stripes glow.
