耐寒分區 11b 的溫度定義為何?
耐寒分區 11b 的定義為年平均極端最低氣溫為 45 °F 到 50 °F (7.2 °C 到 10 °C)。 這是 11 區較溫暖的一半,總範圍從 40 °F 到 50 °F。
該數值是 1991–2020 年氣象紀錄中,每個冬季最冷夜晚的 30 年平均值,用於 2023 年美國農業部地圖。個別冬季的氣溫通常會低幾度,因此耐寒等級剛好為 11b 區的植物,若使用覆蓋物並放置在避風處將會受益。尚未了解自己所在分區的園藝愛好者,可以在比較植物前 透過郵遞區號查詢您的 USDA 耐寒分區。
哪些州屬於 11b 耐寒分區?
11b 區出現在美國本土的 1 個州。根據 2023 年 USDA 官方郵遞區號表,Florida 擁有最多 11b 區的郵遞區號。
- Florida · 11 個郵遞區號
耐寒分區依據海拔和水域劃分,而非州界,因此大多數州跨越了多個分區。
11b 分區適合種植哪些植物?
PlantoScan 目錄中有 348 種植物在 11b 分區具耐寒性,這意味著 11b 分區落在它們的耐寒範圍內。 它們包括 63 種喬木, 71 種灌木, 31 種多年生植物、香草與花卉, 92 種藤本與攀緣植物。

如何在 11b 耐寒分區成功進行園藝?
成功的 11b 區花園依賴於耐寒分區為 11 或更低等級的多年生植物、灌木和樹木。耐寒分區剛好為 11b 的植物通常能度過一般的冬天,但若能覆蓋護根、設置防風林並種植在溫暖牆邊,對其生長更有利。
耐寒分區僅描述冬季寒冷程度。種植日期取決於您當地的春季最後霜日與秋季首次霜日,即使在同一個 11b 分區內,這些日期也可能相差數週——依郵遞區號查詢最後霜日計算器可提供您花園的確切日期。夏季高溫、降雨量和土壤排水性決定了耐寒植物是否能茁壯成長。微氣候也很重要:高架花圃、坡地和鋪面區域升溫較快,而低窪地在無風的夜晚則會聚集冷空氣。
分區溫度與郵遞區號:2023 年 USDA 植物耐寒分區圖,由 USDA 農業研究局與奧勒岡州立大學 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、栽培品種與冬季防護措施會影響植物的存活率。
