Buying Guide
What to consider when buying Oxalis Iron Cross bulbs
- Light requirements: Most oxalis prefer bright, indirect light. Indoors, place near windows; outdoor spots should get partial sun to avoid leaf scorch.
- Temperature and timing: Warm temperatures help bulbs sprout quickly. If planting outdoors, wait until night temperatures stay above 50°F.
- Growth habit: Some sets are compact and suited for desks; others are larger or suited for borders and containers. Choose based on space.
- Water and soil: Use well‑draining soil. Water when the top inch of soil is dry to prevent bulb rot.
- Flowering and foliage: Pink blooms often accompany the decorative foliage. Bloom duration can vary with light and temperature.
- Planting strategy: For a year‑round display, mix Iron Cross with Purple Shamrocks or similar varieties for contrast.
