| | |specimens of R. arboreum,
| | |barbatum, grande,
| | |Falconeri, griffithianum,
| | |and others may be seen in
| | |full vigour, but all have
| | |to receive protection from
| | |the north. Although these
| | |species cannot be grown
| | |successfully outdoors in
| | |most parts of the country,
| | |the hybridist knows their
| | |value. Through crossing

| | |growing and flowering
| | |species many beautiful
| | |hybrids have been raised.
