If you find blue flowers especially fascinating, you are not alone. Many of us consider them highly desirable, but they are always rare. If each spring you want to enjoy the beauty of a blue rhododendron, then here it is – the Blue Diamond Rhododendron. Sparkling, showy, and really, really blue, you simply can’t top this plant for blue beauty. It forms an unusual upright small bush, with small leaves, and blooms early in the season, as soon as April in warmer zones. The large flowers are a pure, clean, un-spotted blue-purple, and make a stunning spring display. This plant also is unusual because it loves to grow in full sun, opening up new spots in your garden for rhododendron growing. 3 feet tall and wide after 10 years, ultimately growing larger, but always rounded and bushy. This is ‘the one’.

  • The best blue rhododendron in existence
  • Unusual form, with smaller leaves on an bushy, multi-branched plant
  • Early blooming, often in April
  • Enjoys and benefits from full sun, if the soil is moist
  • Grow in acidic soil for the best results

The Blue Diamond Rhododendron is unusual in enjoying full sun, but remember the soil must still be moist – it isn’t drought or dryness tolerant. Plant also in areas with morning sun and afternoon shade. The soil must be acidic, with a pH value of less than 6.5, and preferably 5.0 to 5.5. Well-drained, moist, and very rich in organic material, prepare the soil well with lime-free materials like rotted leaves, and use these as mulch each spring too, to conserve moisture and provide nutrients. Generally free of deer or rabbit problems, and with no serious pests or diseases, if the location is right, it will grow happily with little attention. Dead-head young plants by removing the entire flower truss, but no foliage. No need to ever prune or trim, and best left to grow naturally.
