细花丁香蓼 Ludwigia perennis

細花丁香蓼 Ludwigia perennis 也被稱為細花丁香蓼，是一種水生植物，屬於柳葉菜科（Onagraceae）。這種植物常見於濕地、沼澤或水體邊緣，葉片呈長橢圓形，花朵小巧而精緻，多為黃色或淡紅色。小花水丁香因其優雅的外形和耐水性，被廣泛用於水族缸和水景造景中。

適用環境：

水草缸、草缸：非常適合用於各類水族缸中的背景或中景位置，能夠為缸體增添自然的生態氛圍。
溪流缸、雨林缸：也適合在高濕度的環境中種植，如溪流缸或雨林缸的水邊或潮濕地區。

養護要點：

光照：喜歡充足的光照環境，但也能適應半陰的條件。在水族缸中，使用強光照射能促進其顏色和生長。
水分：需要穩定的水體環境，水質要清澈，且應保持水質的弱酸性至中性（pH 6.0-7.5）。
溫度：最適合的生長溫度為20-28°C，需避免低於15°C的溫度，以防止生長受阻。
基質：在水族缸中，使用富含養分的水草泥或細砂作為基質，有助於植物根系的發展。
修剪：定期修剪過長的枝條，以保持植物的形態美觀，並促進新的側枝生長。

小提示：

小花水丁香生長迅速，需要定期修剪以防止過度擴展。
這種植物對光照要求不高，但在強光下會表現出更為鮮艷的色彩。

Ludwigia perennis, commonly known as Perennial Water Primrose, is a graceful stem plant admired for its slender leaves, neat growth pattern, and refreshing green tones. Under stronger lighting, its foliage may shift from bright light green to soft yellow-green or even display a slight reddish tint, giving aquascapes a natural yet vibrant accent. Its upright, elegant posture makes it an excellent choice for midground to background placement in nature-style aquariums.

This species thrives in soft to neutral water and grows best with moderate to high lighting. Although it can survive without CO₂ supplementation, adding CO₂ significantly enhances growth speed, coloration, and stem density. With stable conditions, mature plants may produce small, delicate white or pale pink flowers near the water surface—an attractive detail valued by aquascaping enthusiasts.

Regular trimming encourages lateral shoots and helps maintain a lush, bushy appearance, making it ideal for creating depth and layering within an aquascape. Easy to care for yet visually refined, Ludwigia perennis is suitable for both beginners and advanced hobbyists seeking a subtle but beautiful plant for their aquarium layouts.
