Pinnate Leaves

P80428K.JPGThat refers to the pattern of the veins in the leaves. Long before studying horticulture and botany at Cal Poly, my classmates and I learned a bit about horticulture within the contexts of studying ‘nature’. While in the sixth grade, we all went to camp for a week. One of the many projects we did during that time was collecting a few leaves to represent three different vein patterns, and mounting them under clear plastic on a cardboard plaque. The three different patters were, ‘pinnate’, ‘palmate’, and ‘parallel’. I do not remember if we all used the same leaves, but for my plaque, I got a blue gum eucalyptus leaf to represent pinnate veins. Palmate veins were represented by English ivy. Parallel veins were represented by English plantain.

These two blue gum trees are the same trees that provided the leaf with pinnate veins for my plaque. This is not a good picture. There really are two trees here. The picture below is even worse, but shows that there really are two separate trees. They probably flanked a driveway to the old house outside of the picture to the right. They are not very healthy right now, and do not seem to be much bigger than they were back in November of 1978, when my sixth grade class was here at camp with them.

This camp happens to be right down the road from the farm. We are neighbors. It is gratifying to see that so much of the camp is just as it was four decades ago. The English ivy that was so common back than is completely gone now, probably because it is so invasive. The lawn around the blue gum eucalyptus used to be much weedier, and provided the English plantain leaves for my plaque.P80428K+

Six on Saturday: Camellias on Parade II – Another Sequel

 

The camellias are getting meager, but a few are STILL blooming, even a week after the camellias that were blooming so late last week! These pictures were taken at the same time as those for last Saturday. There were just too many to fit into six pictures. Last week, we had two light pink and four white camellias. These are the dark pink or red camellias. There are no pictures of sasanqua camellias, and we have no reticulata camellias.

1. This is probably the biggest of our camellias. I do not know the name of it or any of the camellias here, but I believe that this is one of the old classics that had been around for centuries, and was popular in the 1960s.P80428
2. If this big ruffled dark pink camellia looks like the last one, it just might be. It does not seem to be as deep red, but that might be a result of the exposure.P80428+
3. You know, I do not typically like this simple pink; and I do not typically like this floral form; but for some reason, I really like this simple pink camellia. It just looks so much like a camellia should look.P80428++
4. This floral form is more refined, but looks almost too perfect, as if the flower were assembled by robots on an assembly line.P80428+++
5. This one also seems to have been assembled, but is a bit friendlier. I happen to like such formality.P80428++++
6. Like #3, this one has an unavoidable appeal. It really looks like a camellia should look, although it also looks like it could use some Grecian Formula.P80428+++++

Wisteria

70426The popular wisterias that bloom so profusely before their new foliage appears in spring are Chinese wisteria, Wisteria sinensis. Others specie are rare. The impressively longer floral trusses of Japanese wisteria are not as abundant, and bloom late amongst developing foliage. American and Kentucky wisteria are more docile small vines, but their floral trusses are both short and late.

Chinese wisteria is also the most fragrant and the most colorful of the wisterias. Lavender is still the most popular and traditional color. White, pink, sky blue and darker almost purplish lavender are also available. The floral trusses, known as racemes, get from half a foot to two feet long. Double flowered cultivars never became too popular because the fluffier blooms are not as elegant. The aggressive vines can reach the tops of tall trees. They rarely strangle limbs or young tree trunks, but have the potential to do so. They are more likely to crush fences and lattice. Wisteria really needs sturdy trellises and specialized pruning for confinement. Vines that grow from seed may take many years to bloom. The pinnately compound leaves turn pale yellow before falling in autumn.

Shade Is Not For Everyone

70426thumbThere is no way around it. Just about every garden has some degree of shade. Even low profile single story houses without eaves or fences are shaded on the north side. Eastern exposures get the cooler morning sun. Western exposures get only the warmer afternoon sun. There are vacant and treeless parcels out in the desert that lack shade, but not many of us are gardening out there.

Shade is very often an asset, which is why shade trees are so popular for shading both gardens and homes. Eaves and awnings are architectural features that shade windows and doorways. Arbors, lath roofs and patio umbrellas provide shade for patios where trees are lacking or insufficient. Without shade, garden spaces can get too uncomfortably warm to be useful during summer.

The problem with too much shade is that, although it makes the garden more comfortable and useful for some things, it also makes the garden less useful for gardening. Roses, vegetable plants and most flowering annuals need good exposure. Lawn, the carpeting for some of the more useful of garden spaces, can be sparse where it is too shaded. Sunlight is as important as shade is.

This is one of the many reasons it is so important to select the proper trees for each application. Big trees are nice, but might shade too much area. Evergreen trees that are good for obscuring unwanted views at a distance, will prevent warming sunlight from reaching parts of the home through winter if they are too close. Neighboring gardens and homes need to be considered as well.

Planning functional gardens is of course not always simple. Most of us contend with trees, shrubbery and vines that are too big and shady, either in our own gardens or in neighboring gardens. Climbing vines like wisteria, honeysuckle and trumpet vine, are notorious for growing far beyond their intended applications. It sometimes becomes necessary to remove overgrown or crowded plants, or prune them for confinement. Big plants that can not be contained will limit the choices for other plants that share their space.

The Late Show

P80425Color in the garden is nice as long as we can see it. There is not so much to see after the sun goes down. That is why some gardens that get used at night are illuminated.

Sometimes it is important to illuminate walkways, driveways and stairways for safety, even if exhibiting the landscape is not important. For such applications, the quality of the light is not as important. Sodium vapor light that works so well for street lamps can make plants look rather sickly. Mercury vapor lamps can make them seem rather pale and bland. Modern LED lamps just look creepy.

So, what happens when foliage that already looks sickly get illuminated by light that enhances the sickly appearance? Well, like many styles of contemporary art, it is a matter of taste . . . or perception . . . or some other big word that a horticulturist neither knows the meaning of, nor has any business using in a sentence.

Golden honeylocusts, as they mature, are not really sufficiently golden to be as pretty as they might look in gardening magazines. Young specimens look good with contrasting purple leaf plums, particularly where warm weather enhances the yellow color. By the time they grow into nice shade trees, and growth is not quite as vigorous as it used to be, the foliage is just rather light yellowish green. They are still very pretty trees, with lacy foliage and light shade that lawn or other plants can grow under. They are just neither here nor there; not bright yellow enough to be flashy, but not green enough to look lush. By that time, their only advantages are that they cast a lighter shade and stay somewhat smaller than those with richer green foliage.

Then the sun goes down. Honeylocusts with richer green foliage are just as bland as any other tree obscured by darkness. If illuminated, they might show off handsome trunks and branch structure, outfitted with distinguished furrowed bark, but not much more.P80425+

This is where the golden honeylocust shines. The paleness of the foliage, enhanced by efficient but aesthetically insensitive light, contrasts with the darkness. It can look spooky. It can look striking. It can look ethereal. I would not know, since I do not even know what that last word means. Regardless, these golden honeylocusts illuminated by common streetlamps in a parking lot at a strip mall really look sharp. It is doubtful that whomever designed the landscape planned it like this. It is just as doubtful than any reputable designer would ever recommend planting a specific cultivar of a long term tree to exploit bad lighting that could change as soon as something more efficient becomes available, but it happens to work in this particular application.P80425++

Flowering Dogwood

80502Flowering dogwood, Cornus florida, seems like it should be more popular here than it is. It blooms spectacularly in April. The foliage can color nicely in autumn. Mature trees are proportionate to medium sized or smaller suburban gardens. However, the limiting factor to their popularity in the local climate is that they are understory trees that prefer to be in the partial shade of larger trees.

They certainly do not need to be shaded all day. Nearby trees or tall buildings that shelter them during the hottest part of the afternoon might be sufficient. Foliage that is too exposed gets roasted by hot sunshine or drying breezes while the weather is warm, especially if exposure is enhanced by glare from nearby walls or pavement. Otherwise, flowering dogwood is not overly demanding.

The abundant white, pink or rarely brick red bloom is actually comprised of modified colorful leaves known as bracts. Each cluster of tiny green flowers is surrounded by four upward facing bracts. Simple paired deciduous leaves develop after bloom. The leaves of some cultivars are variegated with white or yellow. Mature trees can reach upstairs eaves but typically stay lower and broader.

Hedges Are Like Green Fences

80502thumbHedges are a complicated topic! Like lawns, they are among the more functional features of a landscape. They can be used to provide privacy within, obscure unwanted views beyond, or merely to separate a large landscape into cozier or more functional spaces. Except for hedges that are grown for spring flowers or autumn color, most hedges are evergreen with finely textured foliage.

Informal screens, which might also be know simply as informal hedges, can function like hedges, but are a bit different. They are not regularly shorn, so do not need such finely textured foliage. They are either compact plants that stay proportionate to their particular situations, or are grown outside of a refined landscape, where they have plenty of space to grow wild to their natural size.

Although they do the work of fences and walls, hedges do not substitute for them. Fences are relatively ‘low maintenance’. Hedges are quite ‘high maintenance’. They need everything that other plants need, as well as dutiful shearing. Espaliers, trellised vines or vines clinging to fences or walls are also very different, with their own intense maintenance requirements and innate problems.

Most hedges were shorn late last summer or early autumn, but have not done much since then. They should have been shorn early enough for new growth to toughen up a bit to not look shabby or sparse through winter. Now that hedges are growing again, they will need to be shorn again. If space allows, shearing of photinia hedges can be delayed until the red new foliage fades to green.

While hedges get shorn, any volunteer plants that have self sown into them must be removed. Different species of shrubs or vines that sneak in will ruin the symmetry. This is also very important when adding new shrubs to replace any that might be missing. Even different cultivars of the same species will exhibit different color and growth rates. The sides of hedges should be sloped slightly inward at the top to allow more sunlight to reach the bottom, and to compensate for faster upper growth.

Location – Location -Location!

P80422Speaking of which, this is not the right location!

This unhappy Mexican fan palm may have grown here from seed, as they often do. They are notorious for growing under utility cables because that is where birds drop so many of their seed. Perhaps the seed for this one was dropped by a bird perched on the sign many years ago.

Ironic, isn’t it. Birds tend to perch on utility cables and signs and in trees and everywhere that palms should not be planted. How often do they drop seeds out in the open, where whey will not encroach into something as they grow up? Why can’t they drop palm seeds in places where palm trees would actually be an asset? It happens sometimes, but not as often as palms appear where they are not wanted.

The picture below shows three larger Mexican fan palms that were intentionally planted in the original landscape, with a smaller palm between two of the larger palms. The palm in the first picture is barely visible in front of the sign in the background, and is about the same size as the smaller tree that is more visible between the taller trees.

It is possible and perhaps likely that the two smaller palms were not planted intentionally. It is also possible that someone actually planted them.

It does not matter now. The palm in front of the sign needs to be removed. The removal of all the foliage will not kill it. It will generate new foliage that will again obscure the sign if the tree is not eliminated soon. There is no way to prune the palm to divert growth around the sign. It has only one terminal bud, and is unable to generate another if topped. Palms under utility cables have the same problem. Once they get too close to the cables, they must be removed.

Getting back to the first picture. The shock and awe of the defoliation of the subject Mexican fan palm was likely sufficient distraction to prevent anyone from noticing the queen palm foliage peeking around the right side of the sign. Unlike Mexican fan palms, queen palms rarely grow from seed here, especially in a spot where there are no other queen palms nearby. Yes, someone planted ‘another’ palm in the same spot!P80422+

Halston

P80421KHalston, with the help of several friends, could make a nice pill box hat. That is the origin of the name; from pill box hate fame. This might help clarify, https://tonytomeo.wordpress.com/2018/01/27/caution/ . Yes, Halston was a gopher.

Halston was causing some significant damage that was more of a concern than fashion. Halston started by making several large volcanoes under an already distressed ‘Yoshino’ flowering cherry tree right on the edge of the main road. I really did not want any more of the roots to be ruined. I dug into the main tunnels and set traps; but Halston was very elusive, and pushed traps out of the tunnels, and left them unsprung at the surface of the soil.

Halston was very busy last weekend, creating a chain of volcanoes like the volcanic islands of Hawaii. They were right along the edge of a paved walkway, so were both unsightly and messy. Halston had to go.P80421K+

Halston would not go easily though. Excavation into the tunnels was getting to be as damaging as the tunneling had been. I dug to follow the tunnel from the volcanoes for several feet without reaching the main lateral tunnel. I did not want to dig any farther. I had already cut a few small roots, and did not want to cut any more.

Halston compelled me to do something that I had never done before with gopher traps. I was always taught to dig down from the tunnel that comes to the surface, to find the main lateral tunnel, or ‘run’, that continues to the left and right of the tunnel to the surface. Traps should be set in pairs, with one to the left, and one to the right, within the main run. If a gopher perceives a problem in a tunnel to the surface, that tunnel gets abandoned, and the gopher simply excavates a new surface tunnel. However, a gopher is not so likely to bypass a main run. Since I could not find the main run without damaging more roots, I set the first trap in the tunnel that I had dug up for several feet from where it came to the surface, and the second trap in another open tunnel with only a small volcano that was located several feet away.

I really did not expect to catch anything, but to my surprise, all excavation stopped, and Halston was in the first trap when I pulled it up the following morning. Also to my surprise, Halston was quite diminutive! Because of the extend of all the damage, I was expecting a larger gopher. Several more that I would have estimated would be needed for a pill box hat.P80421K++

Six on Saturday: Camellias on Parade

 

The camellias are STILL blooming! They may not bloom profusely, but they have been blooming for quite a while. I do not know how many different cultivars are here, but there are more than I can fit into just six pictures. There are six more for next week, although two might be the same. They are the dark pink or red camellias. For this week, we have two light pink and four white camellias. I did not get any picture of the sasanqua camellias. I have not seen reticulata camellias or any other specie here.

1. This clear pink camellia is probably my least favorite of these six, only because it is a bit too casual for my taste.P80421
2. This clear pink camellia looks more refined. I really like this form.P80421+
3. Now we have white, my favorite color, but the bright yellow stamens in the middle make this casual camellia look like a fried egg.P80421++
4. I happen to prefer this fluffier white, with less prominent stamens.P80421+++
5. Wow! This one really looks yummy!P80421++++
6. Now my favorite; so simple, and so white, although, the camellia in the previous pictures actually looks yummier!4bd5
