Whale's Tongue Agave

Agave ovatifolia will grow into a rather large, solitary plant with broad, lightly keeled, almost unreal, powdery grayish white leaves in a dense rosette. In cultivation it is well adapted to temperate climates. Best of all is that not only it can take drought and very severe freezes without damage, it will also hold up well in cold and damp winters if excellent drainage is provided, outperforming most other Agave in this respect.
