Harold Greer rhododendron
$36
Harold hybridized this rhododendron as a cross between Very Berry and Horizon Monarch and loved the outcome so much he named it after himself! It has pinkish blooms and reaches around 5' tall at maturity. It will grow best in well-draining soil with full sun to partial shade. A cold hardiness factor is not established but this plant is thought to be good in zones 6-9.
