耐寒分區 11a 的溫度範圍是多少?
耐寒分區 11a 的定義是年平均極端最低氣溫為 40 °F 至 45 °F (4.4 °C 至 7.2 °C)。 這是 11 區較冷的一半,總體範圍從 40 °F 到 50 °F。
該數值是 2023 年美國農業部地圖根據 1991–2020 年氣象記錄計算出的每個冬季最冷夜晚的 30 年平均值。個別冬季的氣溫通常會低幾度,因此耐寒等級剛好在 11a 區的植物,若能使用覆蓋物並種植在避風處將會受益。尚未了解自己所在分區的園丁,可以在比較植物前 透過郵政編碼查詢您的美國農業部耐寒分區。
哪些州屬於 11a 耐寒分區?
11a 區出現在美國本土的 2 個州。根據官方 2023 年 USDA 郵遞區號表,Florida 和 California 擁有最多屬於 11a 區的郵遞區號。
- Florida · 169 個郵遞區號
- California · 28 個郵遞區號
耐寒分區遵循海拔和水域,而非州界,因此大多數州跨越了多個分區。
Zone 11a 適合種植哪些植物?
PlantoScan 目錄中有 321 種植物在 11a 分區中可生長,這意味著 11a 分區位於它們的耐寒範圍內。 它們包括 62 種樹木, 66 種灌木, 27 種多年生植物、草本植物與花卉, 78 種藤本與攀緣植物。

你如何在 11a 耐寒分區成功進行園藝?
成功的 11a 區花園依賴於耐寒等級為 11 或更低區的多年生植物、灌木和樹木。耐寒等級剛好為 11a 區的植物可以度過典型的冬天,但如果能覆蓋護根物、設置防風林並種植在溫暖的牆邊,效果會更好。
耐寒分區僅描述冬季寒冷程度。種植日期取決於你當地的春季最後霜凍日和秋季首次霜凍日,即使在同一個 11a 分區內,這些日期也可能相差數週——按郵政編碼計算的最後霜凍日計算器可提供你花園的具體日期。夏季高溫、降雨量和土壤排水情況決定了耐寒植物能否茁壯成長。微氣候同樣重要:高架花床、斜坡和鋪砌區域升溫較快,而低窪地帶在無風的夜晚會聚集冷空氣。
分區溫度與郵遞區號:2023 年 USDA 耐寒分區地圖,由 USDA 農業研究局與俄勒岡州立大學 PRISM 氣候小組提供。植物耐寒範圍來自 PlantoScan 的植物資料庫,僅供參考 — 當地環境、栽培品種及冬季保護措施會影響植物的存活率。
