06 · Flower or harvest
Flowering and seasonal interest
365–800 days to the first expected harvest, bloom, or established display; perennials may need additional seasons to settle. Flowering shifts with planting date, temperature, day length, and cultivar. Deadhead or cut blooms when that practice suits the plant and your goal.
07 · Safety
Know the cautions before you place or use it.
- Plant parts can cause gastrointestinal illness if ingested by people or pets.
