The Rhod odendron Species Botanical Garden invites you to our next webinar on < /span>

\n

November 19\, 2026\, at 5 p.m. PST with Joe Br uso\, hybridizer\, propagator\, and grower of rhododendron species and hybrids.

\n

 Join us for a look at mor e than two decades of hybridizing efforts focused on expressing what J oe calls the “Red Max Effect” in hybrids between Rhododendron maximum and other species and hybrids.

\n

Many rhododendron enthusiasts are familiar with forms of Rhododendron m aximum that exhibit unusual amounts of reddish pigment in their f lowers\, foliage\, stems\, and/or sap. Known as “red maximum” or “Red Max\,” these plants have a fascinating history dating back to the 1930 s\, when an unusual plant was discovered by an engineer working on con struction of the Blue Ridge Parkway.

\n

During this webinar\, Joe will share the results of more than 25 years of hybridizing using a < em>R. maximum seedling known as “maximum RP\,” which he obtained from the Rhododendron Species Botanical Garden. The plant originated f rom the Garden’s accession 75/137\, described as a R. maximum ‘Mt. Mitchell’ form\, selfed\, with erratic marbling and red pigment in the leaves and flowers.

\n

Joe has made hundreds of crosses us ing maximum RP as the seed parent\, with pollen from hardy an d tender species as well as numerous hybrids. A small percentage of th e resulting seedlings have exhibited the Red Max Effect\, with conside rable variation in how the red pigmentation appears and how intensely it is expressed.

\n

Joe will discuss his observations from these crosses\, including examples where the effect appears in flowers\, fol iage\, stems\, sap\, and other parts of the plant. He will also explor e the variability and unpredictability of the trait\, including why so me seedlings express the effect while others do not and why its expres sion can change over time.

\n

One particularly notable cross\, ma ximum RP × Rhododendron elegantulum\, produced the Red Max Ef fect in all seven plants Joe retained through flowering. The resulting plants show considerable variation\, ranging from plants with predomi nantly red trusses to others with a mixture of red\, bicolor\, and pin k flowers.

\n

The presentation follows Joe’s article\, “T he Red Maximum Effect\,” published in the most recent Jou rnal of the American Rhododendron Society.
