The deepest burgundy flowers of any Rhododendron can be found on Dark Lord. The large bundles of trumpet flowers set off the equally dark green foliage perfectly. This Rhododendron would make a great single specimen shrub in a Cottage Garden or part of a larger “collection” of Rhododendrons in an established  woodland garden. The mid-May blooming puts Dark Lord in the middle of the Rhododendron blooming season. 

Rhododendrons for the  most part are self-cleaning. Their large blooms fall off when they are ready exposing the buds that will grow for next year. Deadheading makes them look more tidy, but it needs to be done carefully so the new buds are not disturbed. Beneficial pollinators flock to Rhododendrons not only because they are early bloomers, but the shape and giant size of the blooms make it easy for bees as well as hummingbirds to collect nectar.

Dark Lord Rhododendron Care

Rhododendrons need almost no care to look their best after they have been established. Plant them in average, well drained soil that is on the acidic side. Regular waiting the first couple years will be needed to get a nice strong root base. Longer watering less often will encourage their notoriously shallow growing roots to seek water deeper. Using drip irrigation or a soaker hose will help to keep the trunk and leaves dry. Rhododendrons do not like to have wet leaves. 

Rhododendrons like to be in a shadier spot the higher the hardiness zone. Especially beneficial would be late afternoon shade in the hotter climates to give the evergreen shrubs a chance to rest from the heat of the day. Protection from winter winds in the lower hardiness zones may be needed. Planting in a protected spot that gets plenty of sun will be best for the colder climates.

Dark Lord Rhododendron Spacing

Dark Lord is a medium sized Rhododendron and is useful either at the back of a smaller garden planting or in groups in the middle of a larger woodland setting. The overall size is a height of 5-8 feet with a width of 5-8 feet. Spacing is recommended at 6 feet on center.  Container growing Rhododendrons will help to keep them smaller, if that is the goal. A deep pot that has at least a 24 inch diameter is needed.

    Received plant in beautiful condition, pot soil very nice & mixed well with my soil. Cannot give full review until I see how plant makes it through my NE Illinois zone 5b winters & another season. Still looks beautiful after being in the ground about 2 months. Looking forward to Spring & results.

    I must admit I was initially drawn to these rhodos due to their name. That is simply great branding. I haven't even seen the color of the flowers in person yet, but I know I will love it. The plants arrived promptly, excellently packaged, with new growth on each of them; since being planted they have continued to grow and thrive. I had not had any experience with ordering plants in the mail before, so I had some trepidation about it, but I hadn't seen this particular variety of rhodos in local nurseries so mail order was the way to go. The price was very reasonable and shipping was FREE!! This has been a very, very positive experience, and I would definitely buy from Plant Addicts again in the future.

    Healthy plants. Roots weren’t close to size of...

    Posted by Brady Neal on Jun 04, 2023

    Plants showed up healthy and happy. However, rootball was not quite half the size of 2gal pot once we took them out to plant in the ground. Again, happy healthy plants. Roots just not quite as developed as expected in a two gallon pot.

    The leaf color, size and the flower quality, color and size indicates that it will become a rewarding bush. If the roots had been coming out of bottom of the container and the height had been equally higher it would have been a full 2” pot. What do you feed your plants. Do you change as it gets older or does the condition of the plant dictate.

    Posted by Daniel Guthner on Jun 01, 2023

    The plant was picked up two days after order but then took 8 days for UPS to deliver. It was highly distressed. It will survive but arrived in worse shape than any other plant I have ordered online from other companies. Not the company's fault but UPS took more than a week to deliver and it spent too many days in a hot truck. In the future I will only order from companies who ship FedEx or shippers other than UPS.
