白花穗莼水盾草綠菊 Cabomba caroliniana (Wabi-Kusa)

白花穗莼（學名：Cabomba caroliniana），又稱為卡羅琳水盾、水盾草、綠菊、綠菊花草，是一種水生易養水草，屬於莼菜科。白花穗莼以其細密柔軟的羽狀葉片和潔白的花朵而聞名，葉片呈現出深綠色或略帶紅色，在水中形成美麗的垂直植株。這種植物非常適合用於水族缸、草缸、Wabi-Kusa等多種水景造景中，不僅能增強水族缸的層次感和自然美感，還可為魚類提供良好的隱蔽場所。

適合的造景場合：

• 水族缸：白花穗莼是熱帶淡水魚缸中的理想背景植物，能創造豐富的水下景觀。
• 草缸：其細緻的葉片在草缸中增添了動感和柔和的氛圍，非常適合作為中景或背景植物。
• Wabi-Kusa：白花穗莼在Wabi-Kusa中常作為主要植株之一，能夠豐富景觀層次，並增添自然感。

養護要點：

• 光照：喜充足的光照環境，光線不足會導致葉片稀疏、顏色變淡。建議使用中高強度的水族燈具。
• 溫度：適宜的水溫範圍為20-28°C，耐溫範圍較廣，但不耐寒。
• 水質：適應中性至微酸性水質（pH值6.0-7.5），對水質的適應力較強。
• CO₂供應：提供充足的二氧化碳有助於促進生長和保持葉片的顏色鮮豔。
• 施肥：建議適量添加液態肥料，尤其是富含微量元素的肥料，以維持良好的生長狀態。
• 修剪：生長快速，需定期修剪以維持理想的造型和密度。

小貼士：白花穗莼在強光下會表現出更鮮豔的顏色，並且生長更為旺盛。定期修剪可防止過度蔓延，保持水缸清潔。
