The Rhododendron Garden began in 1988 with 750 plants of 150 varieties. More were added and the total is now over 1,000 plants, and counting. The rhododendrons are planted on a forested north-facing slope of mature deciduous trees with gentle sloping walkways gracing the hillside. Blossoms appear in April and flower into June. Colors vary with many shades of pink, red, white, purple and lavender.
