Six on Saturday: Do You Know The Way To San Jose?

 

These six are not from my garden or landscapes, since I am away from home for now.

Before the evacuations, and before I was even aware of the local wildfires, I came to the Santa Clara Valley for unrelated obligations. Evacuations started in a neighboring town the following Wednesday morning. By Thursday morning, my region was evacuating. I have been here for several days and may be here longer than I need to be if I am unable to return home afterward.

1. Plumbago auriculata – looked pretty when I planted it here, and before I knew how rampant it can get. It really wants more space. The blue is almost too bland. The foliage is rather pale.P00822-1

2. Pelargonium peltatum – is the only one of these six that I did not plant here. I have no idea where it came from. I know this species is nothing special, but this color is too pretty to ignore.P00822-2

3. Chamaecyparis lawsoniana ‘nidiformis’ – is rare here, perhaps because it dislikes a chaparral climate. This specimen is not much bigger than it was when I installed it three decades ago.P00822-3

4. Juniperus chinensis ‘Shimpaku’ – sound as if it is related to Pikachu. Bonsai artists appreciate it more than I do. It is sculptural like a diminutive Hollywood juniper, but grows very slowly.P00822-4

5. Juniperus chinensis ‘Hetzii (Glauca)’ – is known by a few species or hybrid species names, including X media, X pfitzeriana and virginiana, rather than chinensis, most without ‘Glauca’.P00822-5

6. Acer saccharinum – is not one of the favorite maples within its native range; but it happens to be one of my favorites. I grew this one out front by layering a stem from its parent out back.P00822-6

Bigleaf Maple

00729
A maple with unusually big leaves.

Its natural coastal range extends from the extreme southern corner of Alaska to the southwestern corner of California. Another inland range occupies foothills of the Sierra Nevada. Bigleaf maple, Acer macrophyllum, is the most common and prominent native maple here. However, it prefers the seclusion of forested riparian situations at higher elevations locally. It is rare in urban gardens.

Bigleaf maple is best in the wild anyway. It dislikes the aridity of most of the urban and suburban areas of California. (San Jose is in a chaparral climate. Los Angeles is in a desert climate.) Roots of bigleaf maple are potentially aggressive, especially if irrigated generously. They easily displace pavement. Nonetheless, where climate and circumstances allow, bigleaf maple is a grand tree.

Wild trees grow as tall as a hundred fifty feet within forests where they compete for sunlight. Well exposed suburban trees should stay lower than forty feet, while extending their canopies broader than tall. The big and palmately lobed leaves are mostly more than six inches wide. Foliage turns yellow in autumn, and is abundant as it falls. Self sown seedlings often grow under mature trees.

Fung Lum

P00530K
Acer robustum, Chinese maple?

Fung Lum was an architecturally imposing Chinese restaurant in Campbell years ago. It was more famous for the facade of the building than for the food. Although the food was purportedly excellent, not everyone ate there. Everyone in town knew the building though. It was prominently situated right on Bascom Avenue, at a time when the region was still somewhat suburban.

The meticulously pruned and groomed landscape in the minimal space between the ornate facade and sidewalk was mostly rather low so that it did not obscure the architecture. The tallest features were strategically situated to be unobtrusive. Except for only a few of what seemed to be big, sprawling but low profile Japanese maples, there were no other significant maple trees.

‘Fung Lum’ means ‘maple grove’. Commercials on the radio said so. When I was a kid, I therefore expected to see at least a few maples that grew as trees rather than low sprawling mounds in the associated landscape. I figured that the maple grove must be out back where the parking lot was. I sort of wondered if their maples were Chinese, and what Chinese maples were like.

I probably should have been content in believing that the mix of holly oaks, flowering pears and other common trees in the neighborhood were maples. No one else noticed a discrepancy. For all I know, the name referred to a maple grove in China. Maybe the Japanese maples out in front were the grove. They could have been Chinese. Maybe I put way too much though into this.

Now, I actually work with what is purported to be some sort of Chinese maple, perhaps Acer robustum. It really does resemble a Japanese maple. It produces the foliage that can be seen to the right in the last (sixth) picture that I posted early this morning. If it really is a Chinese maple, I would not be surprised if cultivars of this species were what lived in front of Fung Lum.

Springtime On Time

P00405
According to these maples, spring is right on time.

Seasons in the Santa Clara Valley are not very distinct. They are not much more distinct in the Santa Cruz Mountains above. Hot weather in summer does not last for more than a few days, and usually cools off somewhat at night. Winter is never very cold, with light snow rarely falling only on the tops of the highest peaks.

Some believe that summer is our only season, with a few days of ‘not summer’. I would say that it is more like springtime all the time, with a few warm days, a few cool days, and a few rainy days. In many ways, it is great for gardening. However, it can be limiting for species that prefer more warmth in summer, or a good chill in winter. It can also be rather boring.

The vast orchards that formerly occupied the Santa Clara Valley were fortunately satisfied with the mild climate here, and actually enjoyed it. They got just enough chill and just enough warmth, but just as importantly, they appreciated the aridity. Late rain and humidity can ruin the same sorts of fruits in other climates.

Even without much distinction between seasons, springtime in the Santa Clara Valley was spectacular before the orchards were exterminated. A long time ago, tourists came to see it like the fall color of New England. Many or most tourists witnessed it while the weather where they came from was more like late winter. Natives considered the timing to be right on schedule.

However, the schedule did not coincide with what we learned about seasons in kindergarten. We cut out colored leaves from construction paper in autumn, even though there was not much fall color. We cut out snowflakes from white paper in winter, even though most of us had never seen snow. By the time we started cutting out flowers, most spring bloom was already done.

Norway maples always seemed to know what time of year it was. Schwedler maple, which is a darkly bronzed cultivar of Norway maple, was a common street tree in the Santa Clara Valley back then, particularly in tract neighborhoods that were build in the middle of the 1950s. Some disliked how it stayed bare and seemed to be dead after other trees bloomed and foliated.

To some of us, the reddish new growth of the Schwedler maples was what let us know that it really was springtime. Of course, we were done with all our spring planting by then, as allowed by the local climates. Also, the bloomed out orchards were already foliating. The maples just let us know that winter was completely finished and would not be back for several months.

Five young feral Norway maples at work are doing that splendidly right now. They lack the bolder color of the Schwedler maples, but they make the same statement. The bloom of the flowering cherries is exquisite, but not as convincing as the foliation of the maples.

Sugaring Season

P90316KThere is no sugaring season here. Spring comes on too suddenly. By the time sap starts to flow, buds are already swelling.

Bigleaf maple, Acer macrophyllum, happens to be native here, although it is not common. It is the sugaring maple of the Pacific Northwest. A tree next to my driveway gave me enough sap to boil about four ounces of maple syrup a few years ago. That was all I needed to make the point to my colleagues who insisted that it could not be done that it really could be done.

Box elder, Acer negundo, is also native, and in riparian zones, is much more common than bigleaf maples is. I am told that is provides sap for sugaring just like any other maple does. Some say the sap is of inferior quality, or boils to cloudy syrup. Others say that it is comparable to that of any other maple.

Now that I made my point about getting a tiny bit of syrup from a bigleaf maple tree, I have no intention of sugaring again. However, sugaring season is still something that I need to be aware of. It is when I can not prune the maple trees. I can prune them earlier in winter or later in summer, but not while they are most vascularly active during sugaring season. Otherwise, they don’t stop bleeding. Even if the bleeding is harmless, it is unsightly if it stains the trunks and becomes infested with sooty mold as the weather warms.

The same rule applies to birch trees.

I pruned a few of the European white birch, Betula pendula, at work last week, believing that it was still too early for them to be too active. It was not much at all, and involved only a few small upper limbs and two significant lower limbs that had been disfigured by pruning for clearance from adjacent utility cables. I did not notice bleeding from the small stubbed limbs that I pruned from high in the canopy with a pole saw. Yet, the sap started to pour from the pruning wounds before I finished cutting away the two larger lower limbs that happened to be on the same tree. They are still bleeding now. In fact, they are bleeding so much that I feel badly that the tree is losing so much sap. If I had known how much sap would bleed, I could have put a bucket under each of the two wounds to catch the sap to make a small bit of syrup as is done in Alaska.

Bigleaf Maple

81024It is native from the extreme southern tip of Alaska to the extreme southwestern corner of California, but not many of us will see bigleaf maple, Acer macrophyllum, in our neighborhoods. It is planted only rarely, particularly where winters are mild. Relative to other maples, its roots can be more aggressive, and its shade can be darker, so is likely to interfere with lawn and other plants.

Mature trees in exposed situations can get more than fifty feet tall and quite broad. Old wild trees that compete with other trees in a forest can get three times as tall! The big palmate leaves from which the name is derived are about half a foot to a foot wide, and can get a two feet wide on the most vigorous or shaded growth. They turn a nice golden yellow in autumn, even in mild climates.

Bigleaf maple is like the sugar maple of the West. The sap can be processed into maple syrup and sugar. The wood is made into furniture and musical instruments. The very ornamental wood known as bird’s eye maple is derived from burl growth of various maple specie, particularly bigleaf maple. Bigleaf maple is uncommon in landscapes only because it is so aggressive and big.

Sesame Street Was Wrong!

P71231It was probably one of the best television shows for children back then, and probably still is. Everyone of my generation in American remembers Sesame Street. We all identified with it, even if our neighborhood did not look like Sesame Street, or lacked the variety of neighbors. Sesame Street sometimes took us on television field trips to other neighborhoods. Some were more familiar. Those that were more foreign were presented within a compelling and inviting context that got us interested in how other children lived within their respective societies.

Some kids lived in big cities and rode on buses. Others lived in suburban areas with big gardens. Some lived on farms with hens and cows. There were even kids who lived near a forest surrounded by big tall evergreen trees. The trees were probably the firs, spruces and hemlocks of New Hampshire. I do not remember. I just knew I was fascinated with the trees.

I certainly did not need Sesame Street to show me how excellent my first silver maple was. It was my second tree, after my incense cedar. My mother thought of it as ‘her’ maple tree. Yeah, right. When it defoliated in autumn, I ‘raked’ the leaves by pairing them all up, and then pairing all the pairs into groups of four, and then pairing the groups of four into groups of eight, and so on, until there was only a single pile of leaves. When the tree was very small, it had only about sixty-four leaves, so this technique worked just fine. It was a bit more work by the second autumn. By the third autumn, I had learned how to use my little leaf rake.

During this time, I happened to learn something from Sesame Street that I had not previously known about maple trees. They make maple syrup! The kids who lived near the forest in New Hampshire went with their father out to where their maples were, to collect syrup. It was simple. The father gouged the bark, drilled a hole into the trunk, stuck a hooked device into the hole, and hung a bucket onto the hook to collect they syrup! I do not remember if that was the correct sequence of events; but how difficult could it be? The video was only a few minutes long, so I knew that it did not take long for the bucket to fill will with syrup that the kids poured over their pancakes at the end of the video.

What the video failed to explain adequately is that after the bucket was hung, it was left there overnight, and was retrieved the next day. To me, it looked like the kids got distracted and left, but then came right back a few seconds later. The video also failed to explain how involved the process of concentrating the sugar by boiling off the water from the sap. Again, to me, it looked like a pot of boiling sap was ready for pancakes a few seconds later. Like I said, the video was only a few minutes long.

Getting syrup from the maple tree was just too tempting. I took my little plastic beach pail and a small hatched for kindling and went out to get my own syrup. I smacked the trunk with the hatches and grabbed my pail to catch the sap that was supposed to come pouring out; but nothing happened. I smacked the tree again; but again, nothing happened. I gashed the trunk a few more times, in various spots around the trunk, but never got any syrup. Eventually, I got distracted with something else. I left my pail and the hatchet there next to the tree, believing that Sesame Street was wrong.P71231+
