Phenology Daybook: April 10, 2020

April 10th

The 100th Day of the Year

The seasons, like greater tides, ebb and flow across the continents. Spring advances up the United States at the average rate of about fifteen miles a day. It ascends mountainsides at the rate of about a hundred feet a day. It sweeps ahead like a flood of water, racing down the long valleys, creeping up hillsides in a rising tide.

The Daily Weather

Highs reach into 70s five percent of April 10ths; they find 60 degrees 25 percent of the afternoons, and make it into the 50s fifty percent of the time. Cold 40s occur fifteen percent of the days, and 30s come once in a decade or two. The sky is often overcast on the 10th, with totally cloudy conditions occurring 40 percent of the time. Rain is also common on this date: 40 percent of the days bring a shower, and another five percent bring a flurry. But from now on the chance of snow decreases each day until it becomes only one in 100 by April 20th. Frost still occurs an average of three mornings in seven.

Natural Calendar

Past the year’s one-hundredth day, the Lower Midwest is overwhelmed by Middle Spring. The effects of rising temperatures and the longer days are cumulative. Suddenly, the tree line is greening. Mulberry, locust, tree of heaven, viburnum and ginkgo send out their first leaves. Magnolias, redbuds, lilacs, dogwoods, cherries, peaches, apples, quinces, maples, and pears are almost always flowering by the 15th.

At the forest edge, knotweed and nettles are tall enough to cut for supper. Flower heads are forming on the sweet rockets and the garlic mustard. May apples spread their shade across the talus slopes of North Glen. Deep in the woods, the momentum of time and weather opens the soft ginger and raises morels from their mulch. Low patches of wild geranium leaves glow orange in the sun. Buds on the grape vines are swelling. Hobblebush and the privet are filling out. Branches of multiflora roses are almost completely covered with foliage. Along the Little Miami, pale spikes of lizard’s tail are  dragonflies.

In the garden, weeds are getting stronger. August’s great ragweed grows its third and fourth leaves, keeping pace with September’s beggarticks. June’s Dutch iris spears surpass them now, shoot up more twelve inches. Asiatic lilies are emerging. Peony stalks are turning from February red to April green. Daffodils, tulips, and grape hyacinths fill the dooryards.

All across town, honeybees indulge in the seasons of flowering peach trees, forsythia, pears, quince, magnolias, crab apples, cherries, and the last of the Cornus mas. Young hummingbird moths and bumblebees come out to sip the annual mass flowering of dandelions.

As lawn mowing season enters its second week, wild turkeys are gobbling. Late and mid-season daffodils are at their peak, and earlier varieties are gone. Tulip time is here. The delicate fritillary blossoms. Crab apples start their season (last year’s fruit finally falling to make way for the new).

Although some snow trillium and twinleaf are done flowering, it’s budding time for meadow rue, large-flowered trillium, trout lily, Jacob’s ladder, ragwort and sedum. Bellwort leaves unravel. Virginia bluebell, hepatica, periwinkle, toad trillium, cowslip, rue anemone, chickweed, purple deadnettle, spring beauty, small-flowered bittercress, shepherd’s purse, deadnettle, violet, small-flowered buttercup, thyme-leafed speedwell are now all in bloom.

First violet seen along the path. May apples are up three or four inches, their leaves starting to unfold. Box elders have begun to leaf out. Red-flowered toad trilliums are open in places; one trillium grandiflorum has a bud. The buds of the bluebells hang down, emerged from their sheaths of blue green. Deadnettle blooming throughout (I saw it open as much as a week ago). At the park up the street from my house, the red maple flowers are decaying, coinciding with the end of the second season of Early Spring bulbs. First cowslip seen across from the covered bridge.

2004: Returning to Yellow Springs from Asheville: Approaching the Tennessee boarder, we drive into a sudden change of season, the tree line green, and redbuds increasing in numbers. In Knoxville, it is full May, with even violet iris in bloom. Japanese knotweed is at least a foot tall about halfway to the Kentucky border. Redbuds in bloom remain frequent now into Cincinnati, then disappear by Dayton. In Yellow Springs, pears, plums, and the Dayton-Street serviceberries are in full bloom. At our house, the peonies are a foot tall, the red quince, the peach tree and the early tulips are open. The cowslips at the Covered Bridge have come into full flower.

2005: Inventory: Fields around town are purple with purple deadnettle. In the yard, fritillary in bloom, some small jonquils ending, crocus fading, crab apples in full bloom, along with most daffodils and grape hyacinths. Cowslip open at the Covered Bridge. Some full dandelions, red tulips starting at the red crab apples. First young snake seen in the sun. Leaves emerging on the spirea. Astilbe seven inches, cressleaf groundsel six inches, bamboo starting to push up out of the ground, purple buds on the Korean lilac, downtown pears bursting into full bloom, robins singing by 4:30 a.m., cardinals by 5:30.

Daffodils old, some garlic mustard heading. Faint blush to the redbuds. Red quince blooming on Market Street in Vevay. While I was gone, Jeanie heard the green frog croaking in the pond for the first time this year. And she said that one of her kindergarteners came to school with a cup full of baby frogs.

2008: First yellow tulip opened in the south garden this morning. The first pink lungwort flowered under the mock orange. The red quince is budding. In Wilmington, the decorative pear trees have started to come in; there are even a few flowers in Xenia but not in Yellow Springs. The first cowslip is open at the Covered Bridge.

2009: A cool Good Friday, but I saw one bleeding heart in full bloom. Grackles continue to cackle and cluck throughout the neighborhood. Robins are becoming less common, pairing up, perhaps, or saving their energy for early-morning courtship. All over Yellow Springs, pear flowering is at its peak. This evening at the park, I found the first crab apple breaking out.

2010: To the Cox Arboretum in Dayton: Crab apples, lilacs, Judd viburnum, Korean spice viburnum, dandelions, pale yellow Alchemilla alpina, and redbuds full bloom. At home, hearts have formed on the bleeding hearts, Don’s pie cherry full bloom, his wind flowers holding, serviceberry flowers almost gone.

2011: Weeding in the first day of temperatures in the 80s. The first carpenter bees noticed, and the first box elder bug, the first red tulip in the north garden. Daffodils have started to fade. Spirea leaves are thin, well developed. In the heat, Peggy’s pear tree bloomed, and Don’s serviceberry trees.

2012: More leaves appearing on the redbuds as the azaleas gradually open in the cool afternoons. Tulips hold and the last daffodils. On the road south of town, almost all the crab apples have lost their petals. The Korean lilac is trying to open, and the first of the purple wood hyacinths has started to come undone. The wisteria on the trellis is almost gone. Honeysuckle leaves are full-size, Lil’s maple and burning bush leaves almost full. When I cut the grass today, I noticed that most of the violets were done blooming. In the countryside, many dandelion patches hold, even as more apple petals fall. Our redbuds hold at half violet/half tawny. Older sweet Williams budding. All the dogwoods still completely intact.

2013: Katherine says she saw a pair of pileated woodpeckers in her yard yesterday. My pileated has been calling all week – and the red-bellied, too. In the alley at dawn, grackles and starlings in small clusters, cackling and squealing and whistling as they socialize. The lawn is almost getting ready to cut, many areas tall enough, others hardly greening. Next week will be the time. More star magnolias flowering throughout town.

Into North Glen: The broad range of Middle Spring wildflowers in bloom: spring beauties, lesser celandine (found for the first time at the Cascades, all the flowers with eight petals), lush white, violet hepatica, yellow trout lilies, bloodroot, violet cress, and Dutchman’s britches. Toothwort budded, one May apple about two inches out of the ground, and a tiny trillium grandiflorum just emerged. No bluebells or twinleaf seen, but our bluebells are budded at home. Spicebushes are in full bloom throughout the undergrowth on the way to the Yellow Spring. Got back just before the first major thundershower of the year, with hail, too.

2014: One star magnolia bud is almost ready to open across the street. The pussy willows are starting to come down in the wind. A few small tips of hosta found in my garden walk. Daffodils are still in full bloom, grape hyacinths coming in. Driving to Dayton, I saw the first patches of dandelions (very late!) and willow trees greening up.

2015: Spent the day with Tat transplanting. The first cabbage white butterfly of the year visited the northeast garden. The first hostas are visible now, some about an inch high. The  early yellow tulips by the south wall, the first tulips Jeanie and I planted three decades ago, opened over night. Other tulips in the yard have buds. In rain and wind, almost all of the remaining pale bamboo leaves have come down with the pussy willow catkins. Compensation: the new bamboo is coming up.

2016: From Campello, in the hills above Spoleto, Italy Neysa sent photos of a huge patch of purple cyclamens and a tall lilac bush all in bloom, along with a cluster of wild asparagus. If this year’s April hadn’t been so cold, we would be neck and neck with central Italy. At home, the ancient oakleaf hydrangea is starting to leaf; it will have one more year, it seems. The Indomitable Spirit hydrangea is alive and has small buds. In the south garden, the rudbeckia plants that I planted in August are returning, leaves about an inch long, hiding in the weeds. Peach leaves on the new trees are an inch or so long.

2017: Spain: from Brea to Xan Xurgo a few kilometers from Santiago. The hotel is a masterpiece of charm and decoration surrounded by fields and farms. Most of the walk was through eucalyptus woods even past the airport and into the Lavacolla suburbs. Several clumps of cowslips, some spiderwort, yarrow (budding), many butterflies and songbirds, vegetation not so lush as it has been. Maples seen in flower, white seed tufts from flowering trees drifting by as we had lunch by the side of the road. Eucalyptus bark lay all along the path and throughout the forests, skin shedding like sycamores in July. (When do these begin?)

2019: I saw the first pear tree starting to flower this morning at Limestone and Phillips. Peggy’s, though, is just budding. Don’s serviceberry trees have fat buds, should come out in a day or so. I got a great number of ticks from running at Ellis over the past few days – first ticks of the year. At the far end of the pond, small mud turtles were lying out on a log. Leslie reported spicebush blossoms in the Glen.

2020: A chilly wind  throughout the day, but the first bluebell flowers have opened under the ancient mock orange bush near the shed.

And since to look at things in bloom

fifty springs are little room,

About the woodlands I will go

To see the cherry hung with snow.
