种植与播种要点
📅 播种终霜后直接播于土壤或播于穴盘；幼苗长到 10-15 cm 时移栽
🌱 深度2-3 cm
📏 间距30-60 cm（依品种而定）
🌞 光照全日照
💧 浇水中等；保持根区略微湿润，避免淋湿叶片
🧺 收获花盘完全开放且茎秆成熟时（通常60-90天）剪下
🪴 土壤中等肥力、排水良好；过于肥沃的土壤会增加茎高但减少花的数量
⭐ 难度容易
🗓️ 季节春季 / 夏季
📅 日历以北半球为准；南半球请将播种时间推移约6个月。
💡 关键要点: 为了最好地支持有益昆虫的多样性，请选择有花粉（带粉）的品种：无花粉的观赏品种虽能以花蜜吸引蜜蜂，却无法提供蜜蜂所需的蛋白质/花粉来源。定期摘除残花（deadheading）只有在多分枝品种上才能促进再次开花；对单茎品种无效。若想留给鸟类和收种子，可保留花盘。
🤝 伴生逻辑: 与南瓜和玉米（三姊妹种植法中的‘第四个姐妹’）相宜；能吸引传粉者和有益的捕食性昆虫，为黄瓜和番茄提供活的支架和临时遮阴。让它远离马铃薯、蔓生/搭架豆类和大黄：向日葵的根系分泌物（化感作用）会抑制其发芽和生长，而对大黄来说它还是一种害虫（大黄象甲，rhubarb curculio）的替代寄主。与敏感植物之间留出 60-90 厘米的距离。
