Early Horticulture in the Santa Cruz Mountains

Our gardens reflect who we are. Some of us plant edibles while others fill their gardens with fragrance. Some concentrate on native plants, attracting hummingbirds and wildlife while others have a bit of everything.

This area is rich in history. I love to look at old photos and try to identify what the early settlers planted around their homes in the Santa Cruz mountains.

Most of this area was heavily forested until the late 1800′s. Boulder Creek, in 1899, was the 5th largest shipper of timber in the entire country. Quarry operations also used forest trees and shrubs to fuel the lime kilns. Early logging techniques were very hard on the environment. Clear cutting was common and included the understory madrone and tan oak. After the removal of the broadleaf trees, the conifers were cut, to be followed by burning. To clear the bark from the logs and thin the shrub growth to facilitate with log removal, a fire was set. This first fire in itself was no problem since the trees could and would re-sprout from the base. But after removal of the logs by ox team, another fire was set and since these fires were uncontrolled, they would burn surrounding areas as well. The result was a sequence of fires that would kill the growing sprouts and saplings and allow invasion of shrubs, thus delaying the natural reforestation. Burning plus severe soil erosion at times so damaged the land that it could no longer support trees. In other areas the forest did not return until a long successional sequence of brushland to woodland to forest had occurred.

Hebe from New Zealand were all the rage after the 1915 Panama Pacific Exposition in San Francisco.

So what could a woman do to make a house a home back in those days? Many settlers arrived from the east coast, the midwest and Europe and brought with them seeds and starts of plants. As early as 1871 nurseries in San Francisco were importing plants such as pittosporum tenuifolium and the 1915 Panama Pacific Exposition in San Francisco allowed many more plants to become available to homeowners. Hebe from New Zealand were all the rage. The brochure for this world fair describes a Palace of Horticulture and Tower of Jewels as …” a great garden, itself, a marvel of landscape engineering skill… one side of a magic carpet on which these beautiful palaces are set with its floricultural splendors for a wondrous beauty, has never been equaled.”

My interest in early local horticulture started after looking at a friends family photographs from the turn of the century. His family had a resort with a natural spring and rock-lined forest paths close to Highway 9 in South Felton. This was very near the Big Tree Grove resort ( now Toll House ) that opened in 1867. I remember looking at the photos and marveling at all the flowers surrounding the dwelling. The redwood trees have now grown back but at that time there was lots of sunshine, a by-product of clear cutting. I could see roses, lilacs and Shasta daisies in the photo surrounding the wrap around porch.

Years ago I spent some time in the SLV Museum archives looking at old photos of houses dating from 1892 to 1926. I’ll share what I discovered about early landscaping next week in Part II.

Trees for Shade, Wildlife & the Future

Crape myrtles provide summer flowers and fall color.

We don’t plant enough trees. Everyone wants an instant garden but nature doesn’t work that way. When you look out from your windows into your landscaping what catches your eye first? I’ll bet the most majestic and inspiring sight in your garden is probably a tree that frames your house giving it a sense of permanence, welcoming you home and providing a haven for songbirds that serenade you on a summer day.

Large or small, trees make the world go round. They produce oxygen and act as a giant filter that cleans the air we breathe. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.

Trees clean the soil by absorbing dangerous chemicals and other pollutants that have entered the soil. They can either store the harmful pollutants or actually change them into a less harmful form. Trees can filter sewage and clean the water that runs off into our streams. They can absorb and lock away carbon dioxide as wood so it is not available as greenhouse gasses.

If you live near a busy street trees can muffle the noise almost as effectively as a stone wall. They also act as a windbreak during windy and cold seasons reducing the drying effect of the wind and keeping it from blowing precious topsoil away.

Trees slow storm water runoff which helps recharge our aquifers. On top of all the beneficial things trees do for us they provide shade and keep us cool in the summer. In the winter they break up the wind reducing heating costs. Trees increase property values. If you’ve been thinking about adding a few trees to your own property here are some of my favorites. Some don’t get enough recognition others are classics. All make great additions to the garden.

I like Forest Pansy redbud for its stunning red foliage, Sango Kaku Japanese maple for its year round interest, Strawberry tree and Tristania laurina ‘Elegant’. Evergreen Dogwood (Cornus capitata) is also known as Himalayan flowering dogwood and lives up to its name in every respect. This variety is slow growing reaching 20 feet tall in sun or partial shade after about 25 years. After flowering, red fruit provides a treat for the birds.

To make your garden more compelling also consider planting a Ginkgo biloba ‘Autumn gold’ or Amelanchier ‘Autumn Brilliance’. Also called Apple Serviceberry it has edible small fruits you can use in jam and grows fast. Chinese Fringe Tree has magnificent clusters of fragrant, fringe-like blooms and is a terrific accent for small yards.

We are all familiar with the huge flowers in late winter of the Saucer magnolia. This beautiful tree also makes a good lawn tree. Oklahoma redbud takes heat and drought but can also tolerate regular garden watering. Chitalalpa ‘Pink Dawn’ grows 12 feet in three years then grows more slowly to 25 feet with a 25 foot spread. Its pink trumpet-shaped flowers are a welcome sight during the summer. Crape myrtle (lagerstroemia indica) also blooms at the same time providing your garden with color when you’re outdoors the most.

The fruitless Swan Hill olive combines beautifully with iceberg roses and rosemary in this garden.

Swan Hill olive produces no pollen or fruit, takes drought conditions and casts light shade. Chinese pistache provides brilliant fall color growing to 35 feet by 30 feet wide.

Plant a tree for yourself and for future generations.

How to Make your Garden More Sustainable

Yarrow (achillea millefolium) collects phosphorus, copper and potassium from the soil and brings it to the surface.

We all want to do the right thing for the environment by reducing our carbon footprint and becoming good stewards of the land. We want to build our landscapes with green products and incorporate sustainable practices in the garden. A good way to do this is to create gardens that offer food and beauty for people while providing habitat and other benefits for the rest of nature.

Permaculture is the fancy name for this approach to garden design. When you garden using organic fertilizers and organic pesticides you reduce pollution in the environment. When you plant edibles like fruits, vegetables and herbs in your yard, you create a more natural landscape that takes better care of itself while yielding a plentiful harvest of plants for food.

You can put these ideas to work in your own garden by using water more efficiently and carefully selecting and siting plants. Deep rooted trees like fig, mulberry, peach and plum help break up heavy soil and shade the plants beneath them. Planting drought tolerant trees creates shade which in turn slows the evaporation of moisture from soil and prevents erosion.

Group plants with similar water needs. Grow thirsty plants in the lowest areas of your garden where more water collects. You might install a rain garden in an areas like this. A rain garden is simply a planted depression designed to absorb run-off from areas like driveways, walkways, roofs and compacted lawn ares. The rain garden acts to replenish ground beds while preventing water from running into storm sewers, streams and creeks.

Bee’s Bliss salvia is a good low water use ground cover that shades the
soil and conserves moisture as does ceanothus ‘Heart’s Desire’.

Plant dry climate plants like lavender, rosemary and sage in open, sunny areas and drought tolerant ground covers like Bee’s Bliss salvia and ceanothus ‘Anchor Bay’ or ‘Heart’s Desire’ to shade the soil and conserve moisture. Use less turf grass and more walkable ground covers where possible.

Place hardy perennials like artichoke, butterfly bush and rhubarb under tree canopies to conserve moisture. In general, use deep-rooted, low maintenance perennials that provide food and also shade for plants underneath.

For food, plant fruit trees, berries, nuts, herbs and vegetables. To create habitat, plant fennel, spearmint and yarrow for beneficial insects; butterfly bush and sage for pollinators such as bees and hummingbirds, ceanothus and other native shrubs and trees for birds and other wildlife.

To improve soil structure, plant deep rooted plants to break up heavy soils and add organic matter. You can plant rhubarb, bear’s breech or other large leaf plants for a living mulch. Using wood based mulch on garden beds helps contain moisture in the soil, too. To provide soil with nitrogen, plant ceanothus, clover, legumes like beans, and peas and lupine. To supply minerals as compost or mulch plant chives, comfrey, garlic and yarrow. Yarrow is often planted in young orchards to bring nutrients near the top of the soil for young trees to use. S

Sustainable landscapes do not have to look like a weed patch. With a little planning your garden can be beautiful and productive.
