The Gardens of Southern Mexico-Part 1

I’m half way through my trip in Mexico. I started in Tuxtla, the capital of Chiapas, last week and will stop today in Campeche in Yucatan on the Gulf of Mexico. How different are the people, the soils, the climate, the weather and the landscapes of each locale. It’s as diverse as going from Bonny Doon to Pasitiempo to Scotts Valley and then to San Lorenzo valley.

Well, maybe we don’t have alligators and monkeys in our gardens as the people of Canon de Sumidero might have to deal with. But with 50" of rainfall each year they grow bougainvillea, bananas, dates, native succulents and a tall cactus. The residents of the town of Chiapa de Corzo had "sustainable" gardens. At this higher elevation, most people grow what they could eat. Maize, citrus and fava beans are in nearly every small garden plot.

The people of San Cristobal de las Casas, a large city at 7000 ft., grow a little bit of everything. Some plants are cultivated like angel trumpet, impatient oliveri, marigolds and some are native like sunflowers and santivalia. The residents who live in the center of the city have their gardens in courtyards behind large walls which is traditional in Latin countries. Boungainvilleas are common despite the cold weather. It must not actually freeze in the in winter as they were happily growing everywhere.

Nearby, a village called San Juan Chumala had dozens of greenhouses all growing marigolds. The Indian people use lots of these flowers as traditional decorations in religious ceremonies. They are also used extensively on the Day of the Dead which follows Halloween. Every small house grows marigolds as well as maize, squash, fava beans and other edible greens. Long haired black sheep are also common and their wool used in a type of pancho worn by many of the men and in women’s skirts. I also saw fuchsias, tree dahlias and cosmos growing outside houses and small restaurants. Pine tree forests are plentiful at this altitude.

Further up in the mountains in Los Altos de Chiapas, as the area is called, apples grow.  The elevation is 9000 ft. Red clay soil supports pointsettias that are blooming at this time of year.Canna lilies and celosia are commonly grown and the pine trees sported tillandsias and bromeliads in the nooks of the branches. Every garden contained coffee bushes instead of maize here. Asclepias, or butterly weed, grow here but I didn’t see any monarachs.

Passing the continental divide and descending down to sea level on the peninsula, the weather turned more tropical, although still mild at this time of year. The ceiba tree, the source of kapoc for stuffing pillows, is native to this region. Bromeliads, tillandsias, lilies, elephant ears, bougainvillea, coffee, coleus, impatiens and marigolds are typically grown around the house. Scarlet runner beans, morning glories, ficus trees, banana, pineapple, avocado, papaya and gum trees are also common. Red clay soil is typical here, too.

Past the tropical rain forest of Palenque, the Maya ruins, we enter the flat cattle grazing lands in the east part of the state of Tabasco and continue on to the state of Campeche. Cattle egrets by the hundreds gather in the fields. Banana, mango and sugar cane surround small ranch houses. If you live by one of the large rivers, apparently you need to beware of the alligators, especially after a rain. Small, bluish palms are grown to mark the long driveways leading up to the house and horse corrals. Coconut palms, mango, citrus and orchards of "custard apples" grow beside the road. One house was surrounded with potted plants although this is not usual. Blooming water lilies cover some of the numerous ponds. Rainfall here is 70" per year.

Stay tuned for Part 2 of my travels in Mexico as I travel in the Yucatan peninsula from Campeche to the ruins of Uxmal, the city of Merida, the fishing village of Celestun and finally Playa del Carmen on the Caribbean.
 

What Works in your Garden?

I’m vacationing next week in southern Mexico traveling east from the state of Chiapas to the Yucatan peninsula.  In addition to exploring ruins, waterfalls, cenotes and flamingo breeding grounds  I’ll be especially interested in the local plants which vary from  hardwood forests of mahogany and cedar to tropical.  I always study how people landscape around their own homes whenever I travel.  You can get some great ideas this way.  I’ll be sharing all that I discover in next week’s column. 

Around here this is a good time to pull plants that have been struggling now that we’ve had some rain to soften the soil a bit. Pay careful attention to and which aren’t. Be realistic about plants that don’t suit the conditions you have to offer. Replace them with plants that have proven themselves adaptable and well suited to your own garden. Thoughtful editing and repetition are the key to a successful garden.  Such self-sufficient plants require far less work, water, fertilizer and pruning.

Your own personal palette of good plants for your yard are the ones that look most at home planted right where they are. They do best in the soil, sun, wind and weather your garden offers and the maintenance is a snap. These plants don’t have to be the kind of dull and monotonous shrubs that you see around some freeway ramps. They might be the shade-loving native Western swordfern for year round interest.  Planted in masses these ferns aren’t water hogs and look like nature planted them.  Or how about the easy-peasy bergenia cordifolia which will be blooming soon planted as groundcover under the trees? Large, heart shaped leaves grow to 12 across and turn beautiful bronze color in the fall. Pink to rose-red flowers on red stalks appear in late winter.

Camellia sasanqua, with glossy evergeen leaves and showy flowers in fall and winter, can be grown as a shrub or espaliered against a wall. Camellias are easy to grow and an established shrub requires only a deep watering every 10 days or so in the growing season.

Elfin thyme is the perfect groundcover between cracks in pavers paths or other areas that get light foot traffic. And if you want any planting to look better, just pop in a black mondo grass and you’ll have instant sophistication.  Not all "go-to" plants are quite so glamorous, though. Modest, fuzzy little lamb’s ears are high on my list because they grow happily in sun or shade and any kind of soil. Stachys byzantina ‘Silver Carpet’ grows only 12" tall, blooms with purple flowers and spreads to make a beautiful edging or low border

The key to preserving both our backs and the earth’s resources is to choose the right plant for the right place. Keep the plants that are thriving and replace the unhappy plants with a smaller palette of plants that have proven themselves successful in your own garden. Whether these are California natives or plants from other regions that perform well, you’ll be happy you got rid of the malingerers.

New Plants for 2011

I know this gardening season isn’t over yet, but I’m already . Some are already being grown on a limited basis by the wholesale growers while others won’t become available until 2011. Recently I had the opportunity to view up-close and personal some of these new unique perennials, shrubs and grasses. It’s exciting to envision these in our own gardens.

It’s no secret our weather is just about perfect here. That’s why so many of the wholesale nurseries have operations in this county. They know the growing conditions are excellent here for annuals, perennials, grasses and woody ornamentals.

Many of the plants we buy start life as small plugs and liners. Some of these are produced in tissue culture labs located in places such as India, China, Guatemala and Holland. These are then grown on to sellable size by other wholesale growers before they eventually arrive at your local nursery. If you have a Black Mondo or carex grass or a cordyline, hellebore or heuchera it may have been started from a tissue culture somewhere on another continent and has more frequent flyer miles than you do.

Plant tissue culture consists of taking a piece of a plant, such as a stem tip, and placing it in a sterile ( usually gel-based ) nutrient medium where it multiplies, It’s similar to taking a cutting of your favorite houseplant and growing it to share with a friend. The production of plants in sterile containers allows the propagator to reduce the chance of transmitting diseases, pests and pathogens.

One of the new plants that I saw that really caught my eye is the grass,  Pennisetum Fireworks. The variegated pink striped blades of this grass are just as spectacular as the pink flower heads. Some gardens with clay soil and heavy frost in winter may need to grow this plant in a container but it’s worth babying this one, it’s so beautiful.

You may have bought a bright orange Begonia Bonfire this year and were impressed with the hundreds of flowers that it easily produced over the season. Well, next year you’ll be seeing the Sparkle series begonia which is similar. This tuberous begonia is nothing like the classic you are familiar with.  One plant will grow to about 24" in the ground or a container and depending on which color you choose, will be covered with scarlet, white blush, rose or apricot flowers.

And don’t even get me started on all the new mimulus colors that are going to be available next year. The Jellybean series comes in classic orange and gold but also red, purple, pink, light pink, lemon and terra cotta. Remember these are deer resistant, too.

Also there are new hummingbird favorite agastache flavors out now.  Picture in your garden, flower spikes in colors that look like fruit- grapefruit, apricot, grape and orange nectar.

I haven’t even touched on new introductions like Green Jewel echinacea or dwarf butterfly bushes in magenta, violet or pink. How about a bush form of the vine, HardenbergiaMeena will grow 36" tall and have purple flowers in winter.

Look for one of these new perennials next year. It’s going to be a colorful year in the garden.
