Gloriosa Lily 'Rothschildiana' (Gloriosa superba 'Rothschildiana'): Climbing Flame Lilies

Gloriosa lily 'Rothschildiana' (Gloriosa superba 'Rothschildiana') is a stunning, tuberous climber with reflexed, crimson and yellow petals that resemble flames. The flowers nod gracefully from the tips of tendril-tipped leaves that cling to supports.

Growth

This deciduous perennial grows 4–6 feet tall from underground tubers. It blooms in summer. The tubers are brittle and must be handled carefully. All parts are highly toxic (contain colchicine). In zones 8–10, tubers can overwinter in ground with mulch; elsewhere, lift and store dry.

Culture

Full sun to part shade; rich, well-drained soil. Provide a trellis or netting. Water regularly during growth; keep dry during dormancy. Plant tubers horizontally 2–3 inches deep in spring.
