Bob’s Blue Rhododendron: “Compact Elegance in Alpine Blooms”

Enter the world of Bob’s Blue Rhododendron, a charming shrub adorned with petite blue flowers, an epitome of grace in its upright stature. Sporting small leaves, this resilient beauty thrives even in full sun—a rare trait among rhododendrons. At our nursery, it dazzles with its blossoms in the first week of September, boasting flowers the size of a thumbnail.

This alpine variety is a frost-resistant gem, standing strong against cold weather. Witness its winter foliage don a delightful bronze hue, swiftly transitioning to lush green as temperatures rise—a mesmerising transformation.

With leaves no larger than your small fingernail, this plant retains a compact nature. It attains a minimum height of 1.5 meters after a decade, a testament to its steady growth.

For an in-depth visual experience, check out our attached YouTube clip, offering a closer look at this captivating beauty.

When you purchase a rhododendron, you will receive a well-established four-year-old plant grown in a 6L pot, with a strong root system and often developing flower buds, ready to settle in and thrive in your garden.

To help you plan for the plant’s eventual scale, the mature heights listed in the Product Information are estimated 10-year sizes from the time of planting. For more detail, please refer to our Size Guide in the FAQs.

All our rhododendrons are grown in pots, so you can plant them anytime, though autumn is ideal for encouraging strong root growth. Find the right spot based on your chosen rhodo, improve the soil generously with organic matter, gently tease out the roots, and plant shallow at or just below the original soil level. Finally, mulch well and water thoroughly to help your plant establish.
