Rye cover crop at Chanticleer Garden

Who’s Got a Pretty Garden?

The Liberty Bell was not the goal of my recent visit to Philadelphia. Instead, I made a bee-line for Chanticleer (http://www.chanticleergarden.org), a public garden in Wayne, just outside Philly. It’s one of America’s great (as in fabulous, exceptional, matchless) gardens. Like other great gardens — the ones that I consider great, at least — flowers are not the main attraction at Chanticleer.
The beauty of Chanticleer rests, in large part, in its “structure.” That is, the enduring qualities of the views, the shape of the land, the large trees, the paving that leads your eyes and your feet, and the walls.
One special structural feature of Chanticleer is its ruins. Yes, ruins! Not actual ruins, but a stone mansion, roofless and apparently falling apart — all built to look that way. Why? Because ruins add a romantic air to a garden. Dilapidation. Plants re-enveloping the decrepitude, much like the lush trees ready to gobble up oblivious humans frolicking in Fragonard’s Roccoco landscapes. A return to the primitive, to Eden, Nature regaining the upper hand.
Chanticleer’s ruins may look like Nature is gaining control but it’s not so. After all, this ruin was built. The plants, likewise, are planted. So dripping out from crannies among the rocks are chains of succulent plants. Water gathers in nooks (constructed, of course) in which grow water plants. In one “room” that could have been a main hall in this ruined mansion, if it had ever began life as a non-ruined mansion, is a large, stone table with a mirrored surface. The edges of the table actually form a lip which hold the pool of water that makes the table’s mirrored tabletop.
Chanticleer is not all ruin, just one little section. Another distinctive feature of the garden is its sweeps

of grasses. Lawn sculpture, of lawn. So there is mown lawn within which are splayed large sections of tufted, tawny, clumping grasses (fescues, I believe). Cover crops, which are used on farms for soil improvement, are used decoratively at Chanticleer, perhaps also for soil improvement. One 70-foot-long by 15-foot-wide, leaf-shaped bed had been tilled and was sprouting “veins” of rye(?) plants along its length.

Chanticleer sports many annual or cold tender plants distinctive for the size, color, or shapes of their

leaves. Some grow in pots, attractive and distinctive in their own right. In response to my query about how they store all those tender plants in winter, I was told that most were discarded. Chanticleer closes for the season November 3rd.

Oh, and they do have pretty flowers also at Chanticleer.

Returning to my own garden, has Chanticleer now provided inspiration for here? No. My garden is a very different kind of garden from Chanticleer. Chanticleer provides a thoroughly enjoyable feast for the eyes, but not something I need to take home.
The main emphasis here on the farmden (see, it’s not even a garden any more) is edibles, albeit used more or less decoratively, depending on where you look. A feast mostly for the mouth, somewhat for the eyes.
The goal is to produce an abundance of flavorful, nutritious foods pretty much the year ‘round. Year ‘round food is made possible in this climate — here at the farmden, at least — with freezing (many vegetables), common storage (e.g. cabbage, apple, pear, onion, squash), fermentation (cabbage, radishes), drying (tomatoes), one 5’ by 5’ coldframe (lettuce and other salad greens), and a 400 square foot, minimally heated greenhouse (lettuce and other salad greens, kale, chard).
————————————————————–
But wait, now that I look around, things look pretty good around here also. Right now, golden Chojuro

and Seuri-Li Asian pears hang from the branches of espaliered trees sitting atop a stone retaining wall. Atop another retaining wall along the east and north side of the house is a lush, green groundcover of lowbush blueberries, soon to turn a fiery crimson color. Mingling with those blueberries are low-growing lingonberries, whose red fruits are highlighted by the backdrop of the plants’ glossy, evergreen leaves.

(My book, Landscaping with Fruit, details ways to make a fruitful landscape that looks nice and tastes good.)

Way in back, running down the field is a row of pawpaw trees, their large, lush tropical-looking leaves hiding the mango sized fruits now ripening. The creamy white fruits have taste and texture along the lines of vanilla custard or crème brulée. Some of the leaves have begun to shed their tropical look as they turn a clear yellow.
My persimmon trees aren’t hiding their fruits. Those fruits, which give their name to the color persimmon orange color, liven up the trees, and will persist — decoratively, like Christmas ornaments — and

remain edible even after the leaves drop. The fruits, the varieties Mohler, Dooley, and Yates, are delicious, akin to dried apricots that have been plumped up with water, dipped in honey, then given a dash of spice.

And on and on. Very tasty. And nice to look at. But Chanticleer is admittedly nicer to look at.

It (Could Be) Cold

I see a lot of gardens under wraps this morning, plants covered with upturned buckets or flowerpots, or blanketed under . . . well . . . blankets. Day after day of balmy temperatures have made it hard to hold back finally getting vegetable and flower transplants out of their pots and into the ground.
But temperatures just below freezing were predicted for last night (May 13th) and everyone got a wakeup call: Freezing temperatures, which could kill tomato, marigold, and other tender plants, are still possible. It’s all about averages; around here, there’s about a 10 percent chance of a frost the middle of May.
The likelihood of cold, frosty, or freezing temperatures has been detailed — see http://cdo.ncdc.noaa.gov/climatenormals/clim20supp1/states/NY.pdf — for locations throughout the country. The closest weather station connected to that site around here is in Poughkeepsie, and in mid-May that site has a 50% chance of experiencing cold weather (36°F.) and a 10% chance of of experiencing frost (32°F.). Cold air, being heavier than warm air, sinks to low-lying spots on clear still nights, such as last night, so my garden in the Wallkill River valley is usually a few degrees colder than surrounding areas, such as Poughkeepsie. Fortunately, temperatures last night here dropped only to 31° F.
———————————–
Not that lower temperatures would have done my vegetables or flowers any harm. I took the advice I’ve been doling out to others for the past couple of (warm) weeks, and held off planting anything that could be harmed by frost. So tomatoes, peppers, melons, and the like are still in pots that I moved into the warmth of the greenhouse last night.
I’d like to plant out all these cold-tender seedlings but chilly temperatures are predicted for the next few night. Even chilly temperatures, let alone freezing temperatures, are not good for tender plants.
Still, anyone looking out over my garden this morning would have seen white blankets over some beds and overturned flowerpots over a few plants. Because my garden is in a cold spot, temperatures well below freezing were not out of the question for last night. Cold enough temperatures could damage cabbage and its

kin, lettuce, onions, and other cold-hardy transplants that have been growing out in the garden for the past couple of weeks. I had some row cover material readily on hand, so why not, methought, throw it over some of the beds anyway? Just in case.

Throwing covers over plants at 7 in the evening is a lot more pleasant than waking up at 3 am with the sinking feeling that temperatures have really plummeted and then, if they in fact did, running outdoors in the cold darkness to cover plants.
——————————-
Fruit trees, shrubs, and vines present another story. A freeze won’t kill the plants, but low enough temperatures could kill flowers or developing fruit, as it did on many fruit plants last year. One frigid night and you have to wait a whole year for the next crop. Unfortunately, not much could be done about this situation. Fruit plants here are too many or too big to cover. My tack is to keep fingers crossed.
Critical temperatures for fruit damage vary with the kind of fruit, the stage of flower or fruit development, the depth of cold, and the duration of cold. Probably other things, too, such as humidity and plant nutrition. 

An excellent table of “Critical Temperatures for Frost Damage on Fruit Trees” can be viewed at http://extension.usu.edu/files/publications/factsheet/pub__5191779.pdf. So, put simply, 25°F would spell death to 90% of my apples, which are in full bloom, and pears, which are post-bloom, and 28% would do in 10% of their fruits. Plums, also post-bloom, tolerate a bit more cold.
In addition to crossing fingers, my tack is also to grow a variety of fruits, and especially native fruits.

Pawpaw blossom, from below.

(Apples, pears, peaches, and most plums are not native.) It’s not a chauvinistic choice; it’s just that these natives — American persimmon, pawpaw, blueberry, grape, and gooseberry, to name a few — are better adapted to our conditions. And not just the weather here. Pests also.

This spring has been the most perfect spring in a long time, with plenty of clear, sunny days and gradually warming temperatures that kept blossoms from jumping the gun. Playing the averages, the critical cold periods should be pretty much be behind us. As with the stock market, though, “Past performance is no guarantee of future returns.”

Update, May 17th: Warm days and nights that are not too chilly are predicted for the next few days, so I planted out tomatoes and peppers today. I’ll still keep an eye on temperatures because there’s still a 10% chance of temperatures dipping to 36° as late as May 28th according to records at the nearby Poughkeepsie weather monitoring station.
