Saving The Best For Last

Persian ironwoodMy designing life may have been consumed with finishing up as many of our landscape projects as possible, and dealing with the demands of our holiday and winter container work, but the garden has never been far from my mind. Every day, as I am loading up the corgis in the morning, or preparing for them to disembark in the evening, I see what is pictured above. This antique French pot from Biot sits on an Italian terracotta socle, which in turn sits on top of the substantial stump of a maple that succumbed years ago to girdling roots. It was made in the early part of the 20th century by a French pottery that is no longer. I love the shape, the color, and the history. The pale yellow glazed rim finishes the hand thrown raw clay body. There is ample evidence of its age.  Moss spores have infiltrated the surface, and taken up residence. I have never felt the need to plant this pot, as I doubt a planting would make it look any better than it already does.  It pleases me to see this pot every day, in every season, year after year. In the summer, the ground is covered by Sum and Substance hostas, and ferns. In mid-November, the pot is embraced by a pair of Parrotias, just coming into fall color.

persian ironwoodThis essay is not really about my old garden pot. It is about a not so well known and underused small growing tree that saves the best of its beauty for the last of the year. Parrotia persica is the only species in the genus Parrotia. The tree matures at about 25′ tall, and as wide. My group of four trees has been in the ground for close to 20 years, and might be 18 feet tall.  Suffice it to say they grow very slowly. It is irregular growing, and branches out quite close to the ground.  Parrotia persica is one of only two only species in the genus Parrotia. The loosely oblong leaves are quite reminiscent of hamamelis, or witch hazel.  This is not surprising, as they are in the same family. Those leaves have a purple/copper colored  tinge when they emerge in the spring, which matures to a deep  rich green in summer.

Only once in a while do I get fall color like this.  In most years, the leaves turn yellow and peach, long after many other trees have already dropped their leaves. By the time they begin turning color, all of the hostas and ferns that grow in proximity to them have gone dormant.

It is not uncommon for the bark on my trees to have green, yellow, peach, gray and brown coloration all at the same time. The bark does not shed in huge sheets like the London Plane.  I rarely notice the flaking bark on the ground. The literature says that parrotias bloom in very early spring, much like witch hazel.  Clusters of red stamens are surrounded by brownish bracts; the flowers do not have much in the way of petals.  The bloom is subtle.  That said, I have never seen my parrotias bloom.

Though the landscape and garden has gone dormant, this spot is still beautiful in color and texture. These leaves will hold most of the winter, no matter how tough that winter might be.  Some leaves will last long enough to be pushed off by the new leaves emerge in the spring. Should you have a winter season, a parrotia is at its most beautiful at that time of year. The picea abies “mucronata”, or dwarf Norway spruces, and the parrotias completely screen this part of my garden from the street.

The old pot has a sheltered place to be.

I would have thought the damage from the cold and wind would have been most prominent at the top of the tree. I cannot explain what happened, but the trees have begun to recover. I have never seen any damage from insects or disease, and I do nothing to look after it besides watering the hostas around them during dry spells. Parrotias are remarkably healthy and just about maintenance free.

For Adults Only

Some trees delight gardening adults, and gardening adults only.  They do not burst forth dramatically with a blizzard of white blooms in the spring-like a Snowdrift crabapple. There is not a frothy pink blooming ballerina of a crabapple tree in the bunch.  They have no orange and green tulip like flowers on trees closing in on 100 feet tall-as in Liriodendron. 

They have none of the drama of Chamaecyparis Nootkatensis pendula-the weeping Alaskan cedar. None of them are the robustly strong and stately shade trees that ought to be thriving in the tree lawn of every community-the lindens, the sugar and red maples, the zelkovas, the oaks, and sycamores.  They are not a member of the corps of the tree elites-the beeches in all their forms hog most of the room in this category. The Japanese maples consume every spot not taken by the beech. European weeping beech, tri-color beech, Rohani Beech, fernleaf beech-the list is long. The dirt under a mature beech-fit for mulch. No beech suffers any close company in the absence of a feverishly devoted ground-gardener. Acer Palmatum, available in countless permutations-too precious for words. I see them much more than I should.

These architecturally interesting and subtly beautiful trees are not touchy-like the white cercis-and the dogwoods. Any summer day I can see an American dogwood in decline, a Kousa dogwood with wilted foliage and fungus, a birch struggling with borer or ice storm damage, a pin oak with foliage a stark and unpleasant bright yellow from chlorosis.

The adults only trees are never weepers. Weeping trees are hard to respect-admit it. Their tears are relentless. The weeping cherries with their gall-like grafts, the weeping larch, the Camperdown elms-I do not want to come home from work and look at drooping trees-just my preference. So what trees make my adults only list? First and foremost, Parrotia Persica. The Persian Ironwood tree. It grows 20-30 feet tall. It is intimately related taxonomically to the witch hazels. What’s to love here? This small growing multi-branched tree sports subtle witch-hazel like flowers in the spring.   The bark exfoliates as the tree ages. An old Parrotia is a living sculpture with great dignity, and quiet presence. In my garden, it is utterly maintenance-free. Its leaves are disease and insect resistant-my grove of 5 looks great all season long. The fall color varies-but I can count on my Parrotias to hold their leaves really late, and last; most of the leaves hold throughout the winter. Should you be a gardener like me, you tour your garden regularly, and get up close. You give time to seeing it. My parrotias are incredibly beautiful.

On my short list of trees for gardening adults, I have the following criteria. Sculptural branch structure. Great bark. An overall gorgeous shape. Sturdily persistent. Beautiful spring and fall color-this means leaves that make my heart pound. This means the parrotias, the magnolias, the katsuras-and pictured here, the musclewood tree-carpinus caroliniana.  Any tree that makes me think sculpture gets my grown-up attention. 


The leaves are subtly serrated and highly textured; the greenish-yellow fall color persists late into the fall. They branch very low to the ground. They are not showy or dramatic-they are handsome.    


The trunks are indeed muscular. Their winter aspect is every bit as satisfying as the summer.  I have other trees on this short list.  The yellow wood, Cladrastis lutea probably grows the largest.  Maackia Amurensis has glowing green bark, subtle summer flowers, and a beautiful mature shape-very stout, low, and very wide.   

I planted these Lindera glauca var salicifolia quite a few years ago for a client.  Lindera benzoin-the spicebush-is perhaps a better known species. The linderas are shrubs-but they grow large with a minimum of attention.  This species in particular has blue-green willow like leaves.  The texture of the foliage is quite striking.  But it is the fall color- a pale peach-that is a showstopper.  This color persists very long into the fall.  �

The peach will fade to a pale khaki color; the leaves will persist all winter. I took this picture this morning-still peachy November 21. 


I have those days when I am more than willing to be seduced by anything that grows.  In truth, there are probably few trees that I would turn away from my door.  But today, when I tromped around and photographed the parrotias-what fun I had.  Buck asked me what I was doing out there-he could see me from the window.  I told him I was checking out how much my garden, and my gardening, had grown up.
