Large Hybrids

The hardy hybrids have inherited the robust constitution of their parents. Most will tolerate open sites in sun provided their root zone remains reliably moist. They are ideal for most general plantings and may be grown as specimens, as hedges or screens.

This site is purely for information purposes, so we can build up a picture of Rhododendron's people want, but can’t find. You can ask, as I hope you do so, and we will try to find. Thank you
