What’s Old is New Again in Garden Plants

I remember walking with the main horticulturalist at Filoli Garden many years ago and hearing her extol the virtues of the established plantings that have survived drought and neglect with no pest problems for a very long time and are still growing beautifully in the garden. It?s not always the latest cultivars that have staying power. Some of the newer varieties are better but some are not as vigorous, some of those lovely variegated, striped or dark foliage plants revert over the years, some are prone to pests and diseases. Don?t overlook using been-around-for-ages workhorse plants in your garden.

Some of the survivors at Filoli Gardens over the years are California natives and others are just tough plants from other parts of the world. Take the common pittosporum you see in most every old garden. This plant makes a fine hedge, focal point or ground cover depending on the genus with a sweet fragrance in the spring while providing the bones or structure to your garden.

All of the various types of pittosporum are hardy in winter, grow in sun or shade and have low water needs. Pittosporum tobira flowers are scented like orange blossoms. Pittosporum eugenoides and tenuifolium – commonly grown as a hedge or small tree – have highly fragrant blossoms as does the ground cover ?Wheeler?s Dwarf?.

On a recent trip to the Gig Harbor, Washington area, lithodora ?Grace Ward? caught my attention in many gardens. With those electric blue flowers covering this ground cover it?s quite the show stopper. Lithodora is used more extensively than creeping rosemary in the Pacific Northwest as it can survive temps down to 0 degree or less. Growing with only moderate to occasional irrigation give this plant a try in your own garden.

Next plant on my bring-back-the-old-favorites list is the lowly agapanthus or Lily of the Nile.? Sure you see it at every fast food restaurant and hotel you pass but the reason is that it grows and blooms so reliably with little care. This is one plant where the new cultivars are proving to be just a tough as the standard agapanthus africanus.

Agapanthus ‘Storm Cloud’

Agapanthus ?Storm Cloud? produces luxurious green foliage that tinges purple-red in the winter months. In summer large umbels of very deep blue flowers rise above the foliage on tall blackish stems. This variety takes a couple years to establish but blooms reliably from then on.

Two smaller types of agapanthus are ?Queen Anne?, a semi-dwarf variety and the dwarf ?Peter Pan?. Both are available with blue or white flowers. There is also a variegated dwarf called ?Tinkerbell? which grows well also. All agapanthus tolerate frost and neglect and require only moderate watering.

So in addition to all the ceanothus- a California native- that grow so reliably don?t overlook some of these other workhorses. There?s a reason these plants have been grown successfully for such a long time. Be sure you include these old favorites in your garden along with those new cultivars that you just have to try out.

Spring Garden Madness & the Lessons Learned

Everybody?s garden looks the best in the spring. Plants are full of new, healthy growth and the heat of summer has not yet descended. Early flowering plants are at there peak and those that wait until summer to flower so that their nectar will attract hummingbirds, butterflies and bees are patiently awaiting their time in the sun. It?s a glorious time in the garden.

With this in mind I recently strolled Filoli Garden in Woodside to see what they were doing to conserve water while maintaining all their flower power. I also toured 5 gardens in Palo Alto on the Gamble Garden tour and got lots of ideas for sustainable and beautiful gardens.

Filoli Garden is eye candy for any gardener. The estate grounds are maintained to perfection and it was interesting to see what changes they have in store for all those gorgeous, emerald green lawns. The roses, foxglove and peonies were in full bloom, the tulip pots now filled with colorful pansies. Several lawn areas had been reseeded while the large north lawn at the top overlooking the grounds had been allowed to go brown. This is what I learned they have planned to conserve water for the new lawn areas.

Filoli is testing turf varieties that might grow well with less water and mowing in the coastal microclimate of Woodside. They have sown or planted twelve species and blends to trial. Each block will have a corresponding sign telling about the variety. The types being trialed include No Mow Fescue Mix, carex pansa, June grass, U.C. Verde buffalo grass, Pacific hair grass and Molate red fescue. Agrostis pallens, blue grama grass and purple needle grass are also included in the trials.

Many of these varieties are among the lawn replacement recommendations from Scotts Valley and San Lorenzo Water Districts. Rethink you lawn this year like Filoli Gardens and get a rebate, too.

Next on my spring garden tour agenda were several private gardens showcased on the annual Gamble Garden tour in Palo Alto. Because it?s a walking tour I got as many ideas from the gardens featured as I did passing by the front yards of the other houses. This is the neighborhood where Steve Jobs used to live. I don?t know if his family still does but his orchard on the corner lot is thriving.

The theme of this year?s garden tour, Garden are for Living, came through loud and clear in each of the gardens. Many featured sustainable features such as a decomposed granite patio that also serves also as a patanque court, poured in place concrete pavers, corten steel raised bed and path edging and dry laid flagstone paths. Edibles were included in every garden- from a grape-covered pergola to a cleverly designed raised veggie bed complete with steel corners and banding and lighting for evening dinner harvesting.

While walking the neighborhood a low water use plant combination of ornamental olive trees underplanted with rosemary and Iceberg roses complemented one Mediterranean style home. Another garden nearby featured a rustic fence made from fallen tree branches. I must have taken a hundred pictures to remind me of all the great design ideas I saw that day. There is nothing like a spring garden tour to get the creative juices flowing.

A Walk on the Wildside: The Ongoing Saga of the Hillbilly Gardener

Many years ago I was invited by a Scotts Valley resident to visit their garden. This was no ordinary garden I was to learn during my visit and each spring I look forward to seeing what?s new at Doc Hencke?s garden. From his roots in Oklahoma and Texas he describes himself as the ?Hillbilly Gardener? but with his extensive knowledge of trees, vines and just about anything that grows he is one of the most successful and enthusiastic horticulturists I know. I wore my walking shoes and we started talking about what changes he?s noted in his landscape the past few years of drought coupled with this winter?s rains.

First stop- the straw bale veggie garden. The soil in this part of the garden is blue hard sub soil so this above-ground method of cultivation has been a real success. Richard told me that when the bales were first put in place a couple years ago he watered them thoroughly to start the fermentation process. Using a meat thermometer he determined by the internal temperature when fermentation was complete. He then soaked the bales with liquid organic fertilizer and applied some blood meal to augment nitrogen. The straw bales are decomposing each year but he?s going to use them once more this season. His crop of kale, lettuces and chard looked robust and happy.

Nearby a bed of Joe Ghio hybrid bearded iris were in full bloom. ?It?s been a great year for iris?, Richard said. Not so good for peach leaf curl. The rains this winter set the perfect stage for the fungus to proliferate. He joked that the birds get the peaches anyway.

Richard is redoing his pond this year. He?s tired of fighting the raccoons and algae. Steeper sides will deter the raccoons and deeper water will help to prevent algae growth. He was forced to remove a curly willow that shed leaves into the pond as their natural salicylic acid was poisoning the pond.

Last year a new succulent bed was planted along the back of the house and patio. His Sticks on Fire all died over the winter from the cold and rain but the aeonium ?Zwartkop?, echeveria ?Sunburst?, kangaroo paw and various sedums were filling in nicely.

Below the patio the golden Mexican marigold and blue Pride of Madeira were in full bloom along with a gorgeous stand of Weeping Leptospermum. ?Magnificent this year, just look at this plant. Can you imagine what it?s going to look like in another 15 years??, he said. Pointing out the visual boundaries he creates with flowering vines growing up into the trees, Richard observed that some are going better than others. Sound familiar in your own garden? Even this expert propagator is sometimes stymied by Mother Nature.

I love to hear Doc Hencke?s stories as he shows me around. Stopping at a China Doll houseplant that has now grown into a tree he tells me he thinks it?s one of the tallest specimens ever. His giant bird of paradise flower pod opened last week. I?d never seen their enormous blue, prehistoric-looking flowers before.

Richard?s new desert garden along the driveway is growing in nicely with the aloe plicatilis blooming for the first time. Also the yucca he and his brother dug up inTexas is finally blooming. ?I?ve only waited 52 years for it?, he laughs.

There are so many stories that come with each and every plant in Richard?s collection. It?s always a walk on the wild side.
