The north-central area of the garden is the site of the Necklace of Ponds, a network of waterfalls and ponds with a recirculating water system. Many beautiful stone and wooden bridges span the water and provide interesting perspectives of the garden. The Kubota Gardens Foundation holds plant sales in May and September which are open to the public. Basic bonsai care lectures are offered the second Saturday of the month at 1pm, June-September. Tours are Sunday at noon or by appointment.
Admission is free.
The Rhododendron Species Foundation's plantings encompass the largest, most comprehensive collection of rhododendron species and hybrids in the world. This is as much a preserve as a garden - more than 60 of the over 500 species growing here are endangered in the wild. Ferns, an ideal companion plant, are well represented, and the foundation hopes that in time this collection, too, will rank among the world's most complete. The foundation has assembled a collection of gardens on its 22 acres, including a wonderful Alpine Garden with many representative plantings. The garden has a gift shop and plant sale pavilion.
