Four years ago Oakland resident Bill Moyles obtained a grant to develop a garden of these semi-tropical rhododendrons at Lakeside. Few recognize that vireyas (mostly indigenous to the equatorial areas of Indonesia, Malaysia, the Philippines and New Guinea) comprise nearly 44 percent of all known rhododendron species.

Moyles' horticultural acumen encompasses more than three decades of growing rhododendrons from seed: Vireyas grown from seed take about five years to bloom. Sometimes flowering occurs sooner but in many cases later, so a measured patience is a helpful attribute.

The fine collection on view at Lakeside reveals a diverse group of plants blooming year-round. Even December, January and February produce an alluring parade of flowers. Free pamphlets inform visitors as to the availability of Vireyas for Bay Area gardens.

Continue beyond the lath house to an audacious tableau of prickly succulents. Set in black gravel, a picturesque arrangement of blue agaves with, dark teeth (Agave parryi huachucensis) embodies an otherworldly beauty!

Across from the succulents fruit trees grove, and a bit farther along, a mature magnolia lends an aristocratic presence.

Although not currently in service, the Easterbrook Wellhead - an Italian marble water feature - will be the center piece of an anticipated garden highlighting plants for the Mediterranean climate. Cherubs adorning the fountain are delightful harbingers of the Mediterranean Garden Society's planned display.

Continue walking and you will discover the Lakeside Park Palmetum, with palm trees from around the world that are suitable for growing in the Bay Area.

Established in 1978 and planted between 1980 and 1982, the Palmetum is a fascinating procession of palms. Approximately 65 species of palm are complemented by brugmansias with splendidly fragrant trumpets; flamboyant heliconias; and the gold medallion tree (Cassia leptophylla), a Brazilian native and prolific bloomer bearing long spikes covered in deep yellow flowers.

Occupying more than a half acre, the Palmetum is a wonderful place to learn about palm horticulture. Maintained by volunteers, the admirable collection includes the rare Parajubaea cocoides from Quito, Ecuador. Seek out towering Caryota urns, too, with its vaulted leaves: Fishtail palms flower over a period of six or seven years, then die.
