Arbor Day in California

Plant a Strawberry tree like this one. My neighbor Grace loves to sit in it.

California’s Arbor Day is celebrated on March 9th this year. It’s actually a whole week n honor of famed horticulturist Luther Burbank’s birthday. The day is celebrated on different dates around the world because one of the features of Arbor Day is the planting of trees which is best done at certain times of the year in your area. The simple goal of this day is to inspire people to plant, nurture and celebrate trees.

We are fortunate to live in a temperate rain forest with lots of trees. Our redwoods are especially important in our biodiverse watershed as is all flora and fauna in the forest. Redwoods and many native trees keep our environment moist. Let’s make it a priority to protect them and pass the baton of stewardship to our children who will inherit this place.

So whether you’ve been thinking about planting a redwood, heritage oak or other native tree, a fruit tree to feed the family, a shade tree to save on summer cooling, a flowering tree to attract pollinators, or a tree to hang the hammock on this is a good time to plant as well as nurture and celebrate all trees..

Trees are remarkable in how they grow and adapt to their environment. Some trees, like redwood, ponderosa pine, sycamore and madrone have especially beautiful bark. This is the tree’s protection from the outside world. Continually renewed from within, it helps keep out moisture in rain and prevents the tree from losing moisture when the air is dry. Bark insulates against cold and heat and wards off insect enemies.

The inner bark, or phloem, is the pipeline through which food is passed to the rest of the tree, It lives for only a short time, then dies and turns to cork to become part of the protective outer bark.

The next layer in is the cambium cell layer which is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones are called auxins and stimulate growth in the cells. They are produced by leaf buds at the ends of branches as they start growing in spring.

Inside the cambium layer is the sapwood or xylem which moves water from the roots to the leaves. Sapwood is new wood. As newer rings of sapwood are laid down, inner rings lose their vitality and turn to heartwood.

Finally, the central supporting pillar of the tree is called heartwood. Although dead, it will not decay or lose strength while the outer layers are intact. A composite of hollow, needlelike cellulose fibers bound together by a chemical glue called lignin, it is in many ways as strong as steel.

Leaves make food for the tree. Their shapes help them reduce wind resistance, shed rain that could decay the leaf if left standing and produce chlorophyll. The narrow needles of a Douglas fir, for instance, exposes as much as three acres of surface to the sun.

Be kind to all trees. They are a valuable asset to your home and our environment. Earth Day is next month on April 22nd. Let’s continue to celebrate the natural beauty of our planet and learn what we can do to keep it healthy.

California Arbor Week

Plant an ornamental tree for yourself and for the future.

My little garden bounced back pretty quickly after our recent snow. Other than the calla lilies that are none too happy now but will recover the rest of the plants seem just fine. The native and ornamental flowering trees are coming on like nothing even happened. Nature is resilient.

California’s Arbor Day is actually a whole week. A State resolution in 2011 proclaimed March 7-14 as our Arbor Week. Arbor Day is a celebration in honor of famed horticulturist Luther Burbank’s birthday. The day is celebrated on different dates around the world because one of the features of Arbor Day is the planting of trees which is best done at certain times of the year.

Tree Varieties You’ll Love

We have Joyce Kilmer to thank for her poem ?Trees? that starts with the famous line:
I think that I shall never see
A poem lovely as a tree.

In nature and in the garden it?s the trees that get most of the attention. Cambridge Dictionary defines the Wow Factor as a quality or feature?that makes people feel great excitement or admiration. Majestic and dramatic, no matter the size, a tree makes a garden or landscape speak that it?s here to stay.

Brahea armata – Mexican Blue Palm

Recently I had the pleasure to spend some time in a historic garden that dates back to the 1800?s. Last year this garden was featured on the Garden Conservancy Santa Cruz Open Days. The Conservancy?s mission is saving and sharing outstanding American gardens so I was thrilled to tour this garden, be introduced to several new tree varieties plus see some old favorites that might just work in your garden also.

Many of the hundreds of tall bearded iris were still blooming in the garden as well as early flowering perennials and shrubs. I didn?t see any dragonflies flitting about on this particular day but the stunning ornamental gate and mosaic created on one of the garden paths both feature dragonflies and I?m pretty sure they are regular visitors. The garden is called Odonata which is the order of carnivorous insects encompassing dragonflies and damselflies.

An unusual flowering dogwood from Mexico. Cornus florida ‘Pringle’

One of the most unusual flowering trees in Odonata was the Mexican flowering dogwood. This small ornamental tree, a cornus florida subspecies called ?Pringle? had the most unusual flowers. Their white bracts don?t fully open giving them a Chinese lantern look. This tree holds its foliage later than the more familiar Eastern dogwood and has reddish fall color. Glossy red fruit that forms later in the season is readily eaten by birds. This tree is showy and best used where the flowers can be appreciated.

Wedding Cake Tree or Cornus controversa ‘Variegata’

Another dogwood variety growing nearby was also new to me. Cornus controversa ?Veriegata? (Wedding Cake Tree) is graceful and spectacular with beautifully layered horizontal branches. Winner of the prestigious Award of Garden Merit by the Royal Horticultural Society the tree was covered with showy creamy white flowers in flattened clusters. Later the blossoms will give way to black berries in late summer that is, if the birds don?t get them first. Fall color is a lovely yellow color.

Golden Chain Tree aka Laburnum x watereri ‘Vossii’

Also in bloom, a laburnum x watereri ?Vossii? (Golden Chain Tree) looked spectacular with long, drooping clusters of lightly fragrant, bright yellow flowers. This handsome tree has a beautiful spreading canopy of bluish-green foliage and is a great choice as a single specimen or even in a group planting.

Honorable mention awards would have to be shared between the red form of Henry Lauder Walking Stick ?Red Dragon? and the white Flat Rock leptospermum. Well maybe the cryptomeria japonica ?Dacrydioides? (Whip Cord Japanese Cedar) or the pinus wallichiana ?Zebrina? (Striped Himalayan Pine) would also place.

Pittosporum ‘Silver Magic’

There were so many other note-worthy specimens in this garden. From showy shrubs like pittosporum ?Silver Magic? to large palm specimens such as Mexican Blue Palm and a giant bromeliad variety called a puya this garden is a landscape designer?s candy store. I even enjoyed the more common plants like lomandra ?Platinum Beauty?, variegated fortnight lily, a huge heuchera ?a la Rochette? blooming alongside a brilliant blue native pentstemon as well as gold flowering Moonshine yarrow.

It was an afternoon to remember between rain storms.
