Lessons from a Conservatory Gardener: Stephanie Johnson‑Toliver’s Indoor Plant Wisdom

A Gardening Legacy

Seattle’s Volunteer Park Conservatory senior gardener Stephanie Johnson‑Toliver traces her passion to great‑grandmother Leata Gordon (born 1876) and mentor Toshio Kiyonaga, former head gardener. Since joining Seattle Parks in 1978, she’s revitalized the 1912 conservatory’s five distinct houses, added a gift shop, and launched outreach programs—all while dreaming of a contemporary expansion.

Her Philosophy: “Stick with Tried‑and‑True Plants”

Johnson‑Toliver cautions against trying to replicate conservatory conditions at home. Her top picks for reliable houseplants:

• Aglaonema (Chinese evergreen) – ornamental leaves, calla‑like flowers, tolerates low light.
• Aspidistra (cast‑iron plant) – thrives in low light, even a northeast window.
• Sansevieria (snake plant) – drought‑tolerant; strong light encourages blooms.
• Spathiphyllum – leafy, forgiving in low to moderate light.

Indoor Plant Care Tips

• Light: Match plant to window exposure; avoid direct sun that can scorch.
• Soil: Use commercial potting mix; fertilize monthly at full strength spring/summer, half strength (or none) in winter.
• Water: Keep evenly moist in long days, slightly dry in short days.
• Humidity: Mist weekly to deter spider mites.
