Rhododendron × ‘Capistrano’ is a compact, evergreen hybrid rhododendron known for its soft, buttery yellow flower clusters that bloom in mid to late spring. Growing 3 to 5 feet tall and wide, this dense, mound-forming shrub features leathery dark green leaves and an elegant flowering habit. It prefers partial shade and acidic, well-drained soils rich in organic matter. Though visually stunning, this hybrid is not native and offers limited ecological value compared to native rhododendron species.

Why choose ‘Capistrano’ Rhododendron:

• Unique bloom color: Pale yellow flowers brighten spring borders and woodland edges

• Evergreen foliage: Glossy, deep green leaves provide year-round structure

• Compact form: Fits well in foundation plantings or shaded garden beds

Cultivating tips:

• Sun exposure: Thrives in part shade; protect from harsh afternoon sun

• Soil needs: Requires acidic, well-drained, moisture-retentive soil

• Maintenance: Mulch to keep roots cool and moist; prune lightly after flowering

Designs for your garden:

• Foundation plantings: Adds soft color and evergreen structure to shaded entries

• Woodland gardens: Pairs well with ferns, hostas, and other shade-loving plants

• Mixed borders: Offers mid-spring bloom in partially shaded spots

Ecological considerations:

• Non-native hybrid: Offers limited wildlife and pollinator support

• Root sensitivity: Requires careful site selection and consistent moisture

• Visual appeal: High ornamental value in cultivated or designed garden spaces
