One specimen that has taxed Bleddyn above all is one of the Snowdrop Trees
(Rehderodendron), which grows to 100ft in the jungles of Vietnam but has struggled to sprout in the polytunnels at Crug.
These are filled with delicate-looking plants--hosta (several varieties), rhododendron, star jasmine, and several Japanese snowdrop trees
(Styrax japonicus) --to soften the mass of the concrete.
Starting in early spring, there's a rich color palette: yellow Chinese witch hazel (Hamamelis mollis); white, cream, yellow, blue, and pink rhododendrons; white Japanese snowdrop trees
(Styrax japonicus); and Kousa dogwood (Cornus Kousa).
