Rhododendron 'Capistrano'


Item # 47605

Sold Out

The sunniest yellow Rhododendron ever grown, 'Capistrano' is a colorful joy for the late spring garden! Dense, compact, and spreading up to 6 feet wide, it's the ideal size for foundation plantings, hedges, and the back of the border!

'Capistrano' blooms in the middle of Rhododendron season, its unusual golden-yellow flowers glowing in the sunny to partly-shaded garden. A nice change of pace from the familiar pink, white, and red Rhodies, this variety is very hardy and super-easy. Untroubled by pests and disease, it reaches 4 to 5 feet tall and about 5 to 6 feet wide.

Even when not blooming, 'Capistrano' is very attractive, with deep green foliage held tightly on neat plants. A splendid companion to blue-flowered perennials, 'Capistrano' is certain to become one of your all-time garden favorites! Space plants 5 to 6 feet apart. Full sun only in zones 5 and 6. Part shade in zones 7 and 8. Zones 5-8.



Spacing will depend upon ultimate height and spread of the variety or species you’ve chosen. A cool, moisture-retentive, acid soil (pH 4.5 to 6.5), particularly one that contains a high percentage of organic matter to hold moisture, is best.

The location should, in addition, be protected against drying winds and winter afternoon sun. Rhododendrons are shallow rooted and should not be planted too deep: the heavier the soil, the shallower the planting. Do not fertilize at planting time.


Keep plants well-watered, even in dry periods in the fall – a coarse mulch, 2 to 3 inches deep, to retain moisture and keep the soil temperatures cool, is beneficial. This will also keep down weeds, eliminating the need to cultivate, which could pose a danger to shallow roots. Spent flowers should be removed.

A Tradition of Distinction

Wayside Difference Since its founding in 1920, Wayside Gardens has brought the rarest and highest-quality plants to the garden market. Wayside was founded in 1920 by two acclaimed growers who came together to pursue their shared vision of marketing all high-end plants for the serious garden enthusiast. Originally located in Mentor, Ohio, Wayside Gardens swiftly grew a reputation for the highest-quality plants and the most sophisticated clientele. In 1975, Wayside was purchased by the Park Seed Company, and moved to Hodges, SC.  The company has flourished since then, growing to become an undisputed leader in rare and unique plant growing.
