Just a Few of the Plants Blooming Now

Fragrant Blireiana flowering plum

Some years plants bloom a couple weeks earlier than usual but not this year. Our February weather put many plants on hold. Nature?s catching up now. Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite spring blooming trees with a sweet fragrance strong enough to scent the garden. It usually blooms in February in time for my birthday but not this year. Worth the wait. We all look forward to the earliest flowers of the new season. Spring officially began on March 20th.

Forsythia

The cold and rainy weather didn?t stop an old fashioned shrub like forsythia from blooming. They figure prominently in many old gardens because they are tough plants, able to survive neglect and still look beautiful. The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety ?Kolgold? in the 1800’s. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Yellow clivia

Buds are just starting to form on my clivia or Kaffir Lily. What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between dark green, strappy leaves. Even in dark shade they will bloom and brighten the late winter/early spring garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivias are hardy to several degrees below freezing. I have a yellow flowering variety also but I?m not seeing any buds forming yet. Possibly it?s too young. Clivie bloom best when crowded.

Hardenbergia ‘Happy Wanderer’

A beautiful vine that blooms at this time of year is hardenbergia ‘Happy Wanderer’. In the pea family, this evergreen vine looks like a small wisteria when in bloom. Pinkish-purple flowers cascade in clusters on twining stems that reach 12-16 feet long. They require little water once established and are hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn’t live without is Fragrant Sarcococca. The tiny white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won?t grow give this plant a try. They are easy to grow, deer resistant and trouble free.

fungal diseases, succulents

Aloe & other Succulents in the late Winter Garden

Usually succulents are bullet-proof in the garden. Easy care, low water and dramatic they are great additions to the landscape. If you are having problems with fungal spots on yours after so much rain and cold you?re not alone. Still aloe, yucca and agave are worth growing as well as other succulents. Here is some useful information.

Cape Aloe

Succulents have demonstrated a wide tolerance to the fungi that cause leaf and some spots. Although they can disfigure plants they do very little damage despite their appearance.

There are other more serious fungal infections like anthracnose. It often appears as a moist tan colored rot with red, orange or pink pustules on the surface. Spots start small, but expand rapidly on both leaves and crowns. Once a succulents is infected the only treatment is removal of affected leaves. The application of copper fungicide may help to destroy fungal bodies. Root and crown rot don?t respond well to treatment and if you have planted your succulents in well draining soil there might not be much you can do about the excessive rain they?ve gotten recently.

Our Mediterranean climate is usually perfectly suited for the exotic looking family of Aloes. Some hail from the Arabian Peninsula and Madagascar but mostly they are native to South Africa. The spikes of their showy flowers supply much needed nectar for hummingbirds now when not much else is blooming.

There?s a variety for any space, large or small, container or tree-like. Here are a few of the types I?m seeing blooming right now in our area.

Aloe ferox

Aloe ferox or Cape Aloe grows best in full sun but tolerates a wide variety of growing conditions. They can thrive in very dry conditions or grow in an area that receives regular irrigation- a good trait given our recent wet winter. The foliage is hardy to at least 20 degrees and the winter flowers down to 24 degrees. Cape aloe grow to 6 feet tall and 3-5 feet wide so plan accordingly if you plant one of these spectacular reddish-orange to orange succulents. Cape Aloe occupies many habitats in its native Cape Region of South Africa and is listed on the endangered plant list.

Torch aloe

Torch Aloe or Aloe arborescens blooms also in fall and winter. The bright yellow or red flower spikes cover this large clumping variety. This species has recently been studied for possible medical uses similar to the well known aloe vera plant. It?s the only other member of the Aloe family that is claimed to be as effective. It can survive much lower winter low temperatures than aloe vera.

Aloe vera has been grown for thousands of years in tropical climates. It is one of the most widely used medicinal plants on the planet. As a houseplant make sure the pot has plenty of drainage holes as they cannot tolerate standing water. Let them go completely dry between waterings and grow them in the very bright light of a south or west facing window.

The Soap Aloe or Aloe maculata is so tough that it can survive just about anywhere. My soap aloe aren?t blooming right now but others in better growing conditions are sporting showy flowers atop tall, multi branched stalks in colors ranging from red to gold. Once established this succulent needs only occasional water to look good. They grow in partial to full sun. The foliage gets 18 to 24 inches tall with the bloom spikes reaching 35 inches tall.

Every garden should have a variety of aloe to feed the hummingbirds in winter.

Arbor Day, trees

Arbor Day in California

California?s Arbor Day is celebrated on March 7th, 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. The simple goal of this day is to inspire people to plant, nurture and celebrate trees.

Second growth redwood fairy ring.

We are fortunate to live here in the Santa Cruz mountains 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, needle-like 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.
