The Story
Plant Bio
Agave schidigera is a slow-growing, solitary succulent that forms a tight, symmetrical rosette of narrow, dark green leaves. The leaf margins peel back to form thin, curly white threads or filaments.
The cultivar 'Shiraito no Ohi', meaning 'Queen of White Thread', is a particularly beautiful form with a distinct, wide, creamy-white to yellow margin on each leaf, creating a striking variegated appearance.
