Identifying a Large Philodendron selloum and Encouraging Blooms

A 20‑year‑old, 6‑foot plant with a scarred trunk and raised leaf veins is a Philodendron selloum. Blooms are rare indoors but possible.

Bloom Strategy

• Keep potbound—don’t repot.
• Use a bloom‑boosting fertilizer (high phosphorus).
• Provide maximum direct sun.
• Allow soil to dry between waterings (stress encourages reproduction).

Flowers resemble peace lily spathes, staying near the base. Patience is key—it may take years.
