Native Plants for the Santa Cruz Mts

In celebration of Native Plant Week earlier this month, let’s talk about using . How do you pick the best ones for your situation and what do they need to grow in your garden?

California is a vast domain when it comes to natural features and different soils. From hills to mountains to deserts to valleys and ocean bluffs, there are 6000 plus plant species within our borders. Hundreds of these are showy and useful plants worthy of cultivation in our garden. Some, like ceanothus, have already been cultivated for a century or more, both here and abroad.

There are features of the California landscape that present a certain flavor and seasonal progression, quite distinct from that of the subtropics and year-round, moist forests that many traditional garden plants come from. Plants of hilly and mountainous areas are often found in rocky or sandy soils and require well-drained garden soils. Many plants of the chaparral have poor resistance to the root pathogens that thrive in a warm, moist soil and may not tolerate typical garden style irrigation in summer.

Matching or creating the right conditions is the key to success to grow California natives. Planting on a raised mound or berm, for instance, is one way to drain water away from sensitive crowns. Knowing where in California a given native plant comes from can help you make the right decisions.

That being said there are many natives with an amazing broad tolerance of different conditions. Heteromeles arbutifolia or toyon grows in both sandy and clay soils as does Achillea millifolium or yarrow which is also a good cut flower. Carex grass and Erigeron glaucus or Seaside daisy also do well in most soils.

If you garden in clay soils,  good native shrubs are Western redbud, manzanita, spicebush, bush anemone, ceanothus, garrya, Pacific wax myrtle, western mock orange, blue elderberry, mahonia, California wild rose and snowberry. Native perennials for clay soil include coral bells, sticky monkeyflower ( a good cut flower ), salvias, deer grass, rubus and Dutchman’s pipe vine.

Sandy conditions require California natives that are decidedly drought tolerant. You may already grow many of our manzanitas and ceanothus. But do you also have lupine, lavatera, coffeeberry, buckwheat, fuchsia-flowering gooseberry, purple sage, wallflower or the beautiful Douglas iris?

Then there are the folks that live in the shade. Native plants from canyons and riparian areas will do well in your garden. They require some summer watering but that’s all. Native shrubs that tolerate bright shade are manzanita, spicebush, bush anemone, ceanothus, mahonia, Ca. wax myrtle, any of the ribes, wild rose, snowberry and huckleberry. Perennials for color are columbine, Western bleeding heart, Ca. fuchsia, Douglas iris and coral bells.

Where ever you garden, to provide food and nectar or berries for our winged friends be sure you have some flowering currant, sticky monkey flower, coffeeberry, salvia clevelandii, Dutchman’s pipe vine,wax myrtle, Ca. fuchsia, aster chilensis or seaside daisy.

Vines for the Santa Cruz Mountains

If you enjoy and beautiful blooms, you can have them both when you plant vines.  Vines use little space, add color to bare walls and fences, cover free-standing arbors, provide shade and extend the garden skyward.  Vines are amazing plants.
   
If your trees aren’t big enough to provide shade yet , vines on a pergola or lattice work can cool a west facing patio.  They can also block the wind making your garden more comfortable.   Vines with large, soft leaves can soften sounds that would otherwise bounce off hard surfaces.  Birds will love you for your vines.  They offer shelter for many species and nectar for others. 
   
Creating an outdoor room with vines can make your yard feel cozy.  They readily provide the walls to enclose the space.  Views from one part of the garden may be partially open, framed by vines or blocked entirely.  Shrubs can also be used to create garden rooms but vines form a thin living wall that is quickly established.  Creating boundaries with vines also adds vertical design elements to an otherwise flat landscape.
   
Hide something unattractive with a covering of vines. A dog house, old stump, or rock pile can become a pleasant view when covered with vines.  Disguising a concrete block retaining wall with a climbing hydrangea will reward you with a great show of flowers each spring. A native vine like Roger’s Red wild grape or Boston ivy will provide fall color on the same wall.
   
Planting vines in containers or planters on a deck, balcony or paved area can add beauty to these areas. Remember that large containers offer more root space than small ones and require less frequent watering and transplanting.  Vine need support for them to climb.  A small lattice structure or netting stretched between posts works well for vines such as clematis and pink jasmine.  The  structure doesn’t need to be in the container.
   
Combining vines can have twice the effect.  A classic combination is to plant a large flowering clematis like Jackmanii with a rambling rose.  I’ve seen these on arbors and split rail fences and the look is breathtaking.
   
For a vine with long lasting interest, try trumpet creeper which blooms from midsummer to early autumn. Hummingbirds love it. Growing in sun or shade, it can tolerate wet or dry conditions and is generally pest free.  Give it lots of space to grow. 
   
Climbing hydrangea has showy white spring flowers and bright yellow autumn color before the leaves fall.  During the winter months the peeling bark provides interest.  It thrives with a bit of shade and regular moisture.  This is an excellent choice for masonry walls and the trunks of mature trees.  It will clothe a wall with white flowers and turn a dull trunk into a floral masterpiece. 
   
Plant vines for fragrance in your garden.  Evergreen clematis bears showy white fragrant flowers clusters above shiny dark green leaves in spring.  Clematis montana is covered with vanilla scented pink flowers in spring also.   Carolina jessamine‘s fragrant yellow flowers appear in masses throughout  late winter into spring.       
Star jasmine is a wonderful vine for sun or shade and it’s intense fragrance near a patio or open window will delight you.  It is easy to grow and is generally not  troubled by pests. Pink jasmine blooms mostly in the spring but sporadically through fall with showy, sweet scented pale pink flowers.  It grows fast to 15 feet and is tolerant of drought.  It can also be allowed to cascade over a wall or from a hanging basket.
   
Other vines that are beautiful and easy to grow are the native honeysuckle, lonicera hispidula with its translucent red berries in the fall. Violet trumpet vine, white potato vine, passion flower, Lady Banks rose, hardenbergia, Chilean jasmine and wisteria.
   
The above vines are just a few of the wonderful vines that do well in our climate, in a wide range of soils and conditions.  They are pest resistant and need little fertilization or care other than pruning to control size if needed.   Look around your garden for a spot that would be enhance by a beautiful vine.

Quail Hollow & the Gene Pool

Few things can compare to walking on a scenic woodland trail lined with wildflowers.  Now that it’s officially spring I recently took a hike in Quail Hollow Ranch County Park to see what I could find. One of the unique aspects of this park is the number of rare plant and animals that make this valley their home. It didn’t take long to find the threatened Silver-leafed manzanita although it wasn’t blooming yet. The sandhill ecosystem where it grows among ponderosa pine is found in Santa Cruz county and no where else in the world.

Once upon a time, this land was under water, part of an ancient ocean, which uplifted to form the Santa Cruz Mountains about three million years ago. According to the Santa Cruz Department of Parks, the silt, sand and mud that had been deposited in that shallow sea later turned into the shale, sandstone and mudstone that make up Quail Hollow today. The diversity of this special place is mirrored in the patchwork of 15 habitats that are located in this small, secluded valley. Mixed evergreen forest, redwoods, grasslands, and a pond with surrounding riparian ecosystem mix with hot, dry chaparral and sandhill environments. The sandy soils here have eroded from the Santa Margarita sandstone and serve as an aquifer for the San Lorenzo Valley.

Hiking the trails among the blooming mimulus ,large-leafed lupine, Western Hound’s Tongue, manzanita and ceanothus made me think about the impact of our own gardens on the populations of native plants like those here.
Are we contaminating the native gene pool if we plant a mimulus, for instance, from southern California or a hybrid in our own garden?

The genes of all native plants have been sorted out over a very, very long time scale and they’re finely tuned to their environment. When you introduce an exotic gene – exotic meaning not of this place- it could be from a neighboring county, we don’t know the long term effect they’re going to have. If you live next to a wild population of a certain plant, like ceanothus, you should try to plant locally collected and propagated plants and seed. They are harder to find but local growers do collect seed and identify the source. On the other hand, ceanothus is a fire-dependent species and does not regenerate from seed except in the presence of fire or some other disturbance. If in doubt you could substitute a drought tolerant Mediterranean shrub that wouldn’t interbreed with local native plants.

It is probably not a problem for the home owner who lives in a neighborhood and wants to plant a couple of those cool, new sticky monkey flower hybrids in his own garden. If they do interbreed with the native population, in time whatever genetic pollution there is will probably die out. The home gardener is not planting fields of one type of plant that will interfere with the wild population.

There are many philosophies about planting California natives. There is no one-size-fits-all when it comes to this subject.  One thing for sure, we all want to preserve our wild areas like Quail Hollow.
