Here in the Piedmont region of North Carolina, winter is refusing to relinquish its grip. We’re not buried under feet of snow like our more northern neighbors, but the cold air refuses to head back to the Arctic, and frequent precipitation events teeter between rain and ice, often producing both forms in one episode.
Last Saturday, it snowed all day and into the night, but almost none of it lingered, because the previous day we had soared into the upper 60-degree range. It was fun to watch enormous wet snowflakes fall steadily while the Spring Peepers droned enthusiastically in the adjacent swamp. They didn’t quiet until the sky cleared and the temperatures plunged, turning melted snow into treacherous black ice.
Late winter temperature variations don’t seem to bother salamanders any more than they do Spring Peepers, as demonstrated by the top photo. That’s a salamander egg mass. We’ve observed several species of these amphibians on our property, so I’m guessing when I identify these eggs as those from a Spotted Salamander. I’m going by the description of egg-laying behavior at the link provided. Those black dots are the growing embryos encased by the gelatinous material that protects them until the new-born amphibians are ready to emerge.
Sunday morning after the sun melted icy walks, Wonder Spouse and I wandered up to the vegetable garden to discuss our immediate to-do list preparations for the spring garden. I’ve sowed quite a few (seven, I think) varieties of spring greens in the greenhouse. I’m hoping they’ll be ready for transplanting in mid-March, weather permitting. We have much to do to ready planting beds before that time — if winter will stop covering my garden in ice!
While we were there, we realized our abundant chive plants have begun putting out fresh shoots, despite winter’s persistence.
It’s a good thing that members of the onion family are relatively cold-resistant, don’t you think?
On Sunday night, temperatures plunged into the teens. The National Weather Service’s official recording station at our airport recorded a low of 18 degrees Fahrenheit. The thermometer on our hill got down to 13 degrees. Microclimate differences and the absence of nearby concrete and asphalt heat islands account for our consistently lower temperatures.
Fortunately, native plants are well adapted to our up-and-down temperatures, as evidenced by the native rhododendron (Rhododendron maximum) that grows beside our back deck. This species is common in our mountains, but it does occur naturally in a few places in the Piedmont region, where so-called relict plant communities from the last glacial period survive to present day. I would never have planted this species where it grows in my yard, but it was here when we moved in 23 years ago, easily tripling in size since then, so I don’t argue with it.
Here is what the rhododendron looked like at 7:20 a.m. Monday morning, when our thermometer read 13 degrees:
See how sad the leaves look? The shrub is fine; this is how evergreens adapt to severe cold. They temporarily shut down their leafy water transport mechanism to protect leaves from damage. But the plant does look pitiful, as evidenced by this closer view:
A mere two hours later, the shrub’s protected southern exposure combined with strong sunlight helped the plant recover its composure.
So adept is this plant at its cold-recovery trick that you’d never know how sad it looked two hours earlier.
Such is the nature of Salamander Season here in the Piedmont. One minute, we’re shivering in frigid air, the next, sunlight and Spring Peepers warm us into spring garden dreams.
Friday’s forecast is calling for morning sleet that should morph into cold rain. Although inconvenient, I am grateful for every drop of precipitation. My county remains in moderate drought, a thirsty peninsula surrounded by well-watered counties to our east, north, and west. I will happily delay spring planting for mud-making rain, knowing we need that water to fight summer’s inevitable drought-worsening heat.
All avid gardeners have their secrets for producing a great garden. Some of us save our own seed and bulbs, nurturing a plant line until it is maximally adapted to flourish in our garden. I know a farmer’s market vendor who has done this with the garlic variety he sells. Garlic can be tricky to grow in the middle of NC, but he has laboriously saved the best bulbs from his crops every year, until now his entire crop laughs at the wild swings in temperature and moisture levels that challenge growers in my region.
Some gardeners add secret ingredients to their soils that they swear improve the vigor of their plants. Others plant only on certain phases of the moon. The list of gardening tricks and secrets is likely as long as the list of experienced gardeners.
I have my own little secrets and tips, many of which I have shared here. Early on, I realized my greatest asset — my secret blogging weapon, if you will — is the magnificent photography of Wonder Spouse. The best photos on this blog are all ones he has taken of the plants and animals who dwell with us on our five-acre patch of North Carolina Piedmont.
In going through my files today, I realized that he had given me a number of gorgeous photos that, for one reason or another, I haven’t shown you. Today, I am rectifying that oversight by sharing some of Wonder Spouse’s recent work, starting with that opening image. To fully appreciate these photos, click on them to see enlarged versions.
He took that close-up of a cluster of Winterhazel flowers in the middle of March. It took his artistry (and his fancier camera) to convey what I tried to describe to you here.
In mid-April, he took this gorgeous shot of a flower bud cluster of Rhododendron flammeum ‘Scarlet Ibis’ before the flowers opened:
At the end of April, Wonder Spouse took several breath-taking photos that I want to share. This first is of an evergreen rhododendron that was growing beside our back deck when we moved in 23 years ago. I think it’s R. maximum, the species common to our mountains, and I doubt it’s a named cultivar. Somehow, it has managed to flourish beneath the enormous Northern Red Oak that towers over our home. This shrub is now twelve or so feet high and eight feet wide, and it blooms reliably despite near complete neglect on my part. Here’s Wonder Spouse’s shot of an open flower cluster during peak bloom last week:
Wonder Spouse is a big fan of Amaryllis cultivars. Many years ago, we bought several choice varieties, and they’ve been multiplying in their pots ever since. I overwinter them in the greenhouse and bring them inside or decorate our back deck with them when their thick bloom stalks appear. Here’s a close-up of the flowers of Amaryllis ‘Picotee’ that are still blooming on our back deck:
To close, I want to share this “glamour shot” of one of the bearded iris varieties that thrive in our yard despite my less-than-optimal care. I’ve long forgotten the cultivar name, but the flowers are a lovely coppery orange color. I cut a stalk full of buds and put it in a vase on our kitchen counter, where we could appreciate its beauty and its gentle, sweet scent. One evening last week, Wonder Spouse was inspired by the effect of the overhead counter light on the iris bloom. Without bothering with a tripod, he photographed this iris in our darkened house. I think you’ll agree he captured the essential exquisiteness of this bloom:
Thus, I have revealed my blogging secret weapon for all to see: the photography of the amazingly versatile Wonder Spouse. He makes our garden and yard look far better than I ever could show you with my pictures or words, and I deem myself the most fortunate of gardeners to be able to call upon his many talents.
