Diagnosing Brown Streaks on Variegated False Agave

Mystery Plant with Brown Streaks: Need Photo for ID

Owner has a "variegated false agave" (2–3 ft) from Lowe's clearance with brown, shriveled streaks in leaves, some sapping, holes along variegation. New pups show same streaks. In Seattle, left in snow.

Response

Cannot identify from description (could be Agave, Aloe, Yucca, etc.). Requested photo to greg8365@hotmail.com to assess damage and hardiness.
