Plant Highlights This Week

Flowers are one of the most pronounced markers of the progression of time in a garden. Each month we scout the Garden for amazing blooms and feature our favorites here. Check back often to see what we have in store for your next visit to Filoli.

Garden Happenings
Week of March 30 – April 3, 2015

New Plantings:
Replacement planting in annual beds as needed; additions to cutting garden beds as plants are ready.

Plant Highlights:

The peak of spring has arrived! Now, through the first week in April, is the time to see the garden at its most colorful!

Containers of tulips and daffodils are in bloom all over the grounds this week. All of the bulb pots have gone out into the garden, with many having already come and gone.

The tulips in the Sunken Garden, the Sundial and Dutch are all at or near the peak of bloom.

Weeping cherries, a guest favorite, have begun to bloom! They will probably be at their best the next week or so.

The Numbered Beds, planted with ‘Red Impression’ tulips, are past prime, but still blooming.

The Daffodil Field, west of the main house, and planted with ‘Golden Dawn’ is blooming.

Camellias–Camellias–Camellias! Both the Japonicas and the Reticulatas are still loaded with blossoms. I can’t recall a year when the flowers have been as large, vibrant and flawless!

Many wisteria vines are blooming and looking gorgeous!

The lilacs along the yew allée are coming into bloom or are in full bloom. Be sure to stick your nose in one truss or another.

Evergreen clematis (C. armandii) are blooming at the Wedding Place, on the Garden House, and other locations.

The Camperdown Elm with its gnarled branches, bare to the world, is a spectacular sight to behold.

The annual beds are showing quite a bit of color with these warm days. Violas, forget–me–nots and the catchfly (Silene dioica) in the Sunken Garden have lots of flowers. ‘Jersey Jem’ violas in the Chartres are showing significant color.

Various spring-blooming shrubs are in bloom including azaleas, rhododendrons, ‘The Bride’ pearl bush (Exochorda) in the Walled Garden and the shrubby pearl bush (E. racemosa) along the Yew Allee. The ‘Ward’s Ruby’ azalea on the west side of the house is at peak.

The Lady Bank’s roses are blooming and stunning. The crabapples and redbuds are at or near their peak of bloom. The first of the tree peonies are flowering! The plants seem healthy this year due to the drier weather.

Irish yew shearing. Pots of pansies being filled. Lots of grooming throughout the garden.

Notes and Common Questions

Drought Status
Last year’s drought situation was not fun for anyone. But, you have to make lemonade when you have lemons.  By the end of the 2013-14 rain season, we received only 12.01”.  Since our annual average is over 33”, this was not only a considerable shortfall, but also the driest year since we began keeping records in the late 70s.

The current season looks a lot more promising, but we’re not counting our chickens yet.  December brought 15.32” (!) of rain and increased the 2014-15 total to 18.60”.  We were extremely optimistic going into January, but with 0.00” of rain last month, we’re now cautiously optimistic.  With over 5” of rain in February, we’re now just over 24”.  This is twice the rain we received last year, but we still have a ways to go.

Service Courtyard Lawn
In an early effort to save water this year, and also to better protect the roots of the flowering cherries, we are mulching over the lawn in the Service Courtyard / Plant Shop.  With many above-ground roots that are regularly nicked by weekly mowing, we hope that these trees will fare better with the added TLC.

Historic Cycad Status
The December 2013 (a low of 16°) freeze scared many of us because of the immediate impact it had on many plants. Throughout the garden, various trees, shrubs, vines and annuals were affected. Some of our citrus was particularly hit hard, as were the forget-me-nots in many of the beds. In the end, all of the plants survived and most had rebounded by spring.

The one plant of particular concern was the historic cycad (Lepidozamia peroffskyana) that had been in the Woodland Garden. All of the frond-like leaves turned black after the hard frosts. Soon thereafter, we made the decision to dig up the plant, plant into a large terra cotta pot, and keep it in one of our greenhouses. Within in a month, the plant had sent out a new whorl of leaves and seemed very happy during the remainder of the year. In fact, by late 2014, the cycad produced a reproductive “cone”, that is still growing and developing.

Cycads are in the gymnosperm group of plants and are related to the conifers (pine, redwood, etc.) and the ginkgo. They are a more primitive and thus their reproductive structure is cone-like, but not the more evolutionarily-advanced cone of the pines. The unusual thing about cycads is that they are dioecious, meaning they have separate male and female plants. (This trait is found in other plants, including some flowering plants.)  We will have to wait until our “cone” has matured before we know what sex our plant is, but by the clues of its shape and position on the plant point to it being male.

Southern Magnolia Propagation
Another plant of concern discussed in the Garden Happenings in 2014 was our iconic southern magnolia. The cause of the thinning of the crown on the southeast side, at this point, has not been determined. Thus, we have embarked on a two efforts to propagate this historic tree. We have taken traditional cuttings , which are in our propagation house. More noteworthy, are the air-layer cuttings that are presently in-process.

As a tree matures, it typically becomes more and more difficult to propagate. One technique that sometimes proves more successful is starting the rooting process on small branches while still on the plant. Here, moist, sphagnum moss is wrapped around the branch base and is enclosed by a dark plastic wrap. The idea is that the moist, dark conditions mimic the soil environment, which promotes roots to grow. Sometimes the process can take several months, so we are hopeful that this technique will eventually produce rooted cuttings. You can view these in situ cuttings looking into the lower canopy from the north (main house) side of the tree.

Bloomin’ Bucks Program
Whenever visitors, volunteers or anyone else asks about where Filoli purchases our bulbs, after telling them that the bulk of our bulbs are purchased wholesale from the Netherlands, I tell them the best retail vendor in the US that I know is Brent and Becky’s Bulbs. Brent Heath’s family has long been in the bulb business and because of their lasting relationships with the Dutch growers, Brent and Becky are able to sell top quality bulbs. If Filoli could afford to buy all of their bulbs from this company, we would.

As part of the company’s commitment to public gardens, schools and other non-profits, Brent and Becky established the Bloomin’ Bucks program. With each purchase from Brent and Becky’s through the program, the designated non-profit receives 25% of the funds. Filoli is a participant in this program. So, if you’re planning to order bulbs this year, and like Brent and Becky’s products, please go to the Bloomin’ Bucks page ( to start your purchase by choosing Filoli as your non-profit of choice. From there, you will be sent to the regular Brent and Becky’s Bulbs website to start your shopping.
