體型

在原生地高度可達8公尺、幹徑可達30公分。盆栽可保持小型

澆水

生育期間適度給肥

光照和放置位置

不需要強烈日照。在明亮的半陰環境中管理。

澆水

如果用土排水良好，生育期間可以充分澆水。澆至盆底流出為止，之後等土壤稍微乾燥後再澆。

溫度和越冬

冬季落葉。冬季澆水減少至約一月一次，氣溫降至約10℃時停止澆水。

用土和換盆

關於奇異葉下珠

Phyllanthus mirabilis is a Thai caudiciform plant with twisting branches and glossy pinnate leaves that fold shut each evening. An intermediate-level species whose caudex thickens gradually over many years.

開始照料奇異葉下珠前需要了解的7件事

1. 1Bright Partial Shade

   Phyllanthus mirabilis doesn't need strong sun; keep it in bright partial shade. Crowded foliage traps moisture, so space plants apart for good airflow.

2. 2Water With Clear Wet-Dry Cycles

   During active growth, water thoroughly once the soil surface dries out, letting the caudex store moisture. As the plant slows down and enters dormancy, cut back on watering to keep the roots on the drier side and avoid rot.

3. 3Choose a Fast-Draining Mix

   A caudiciform-specific potting mix, or a blend of akadama and pumice, works well for good drainage. Since excess moisture can damage the caudex, make sure the pot itself drains freely too.

4. 4Repot During Active Growth

   Once roots fill the pot, move up to a slightly larger container during a period of active growth. Handle the roots gently, and plant shallowly so the caudex isn't buried too deep in the soil.

5. 5Bring It Indoors in Winter

   As a native of tropical Thailand, this plant is sensitive to cold. When temperatures drop, move it to a bright spot indoors, keep it warm, and water more sparingly while it rests.

6. 6Watch the Leaves Open and Close

   Each evening, the leaflets fold together in pairs like a butterfly closing its wings, then reopen in the morning. This daily rhythm is one of the plant's most distinctive features and can also hint at how much light and warmth it's getting.

7. 7Picking a Healthy Plant

   Look for a specimen with a firm, unblemished caudex at the base. Since this species is considered suited to intermediate growers, first-time caudiciform keepers may want to research its care before bringing one home.

奇異葉下珠的常見問題

Q.How long does it take for the caudex to swell?

A.Caudex growth is a slow process — a base more than 10cm across usually belongs to a plant that's been growing for several decades. It's a plant to enjoy patiently over the long term rather than rush.

Q.Is this a good plant for beginners?

A.This species is generally considered suited to intermediate growers rather than complete beginners. Some prior experience with watering and placement for caudiciform plants will make it easier to care for.

Q.Why do the leaves close in the evening?

A.It's a natural trait of this species — the paired leaflets fold together each evening, much like a butterfly closing its wings, and reopen again the next morning. It's simply part of the plant's daily rhythm and one of its most charming characteristics.

Q.How large does this plant get?

A.In its native habitat it can grow into a tree up to 8 meters tall with a trunk around 30cm across. In a pot, however, its size can be kept much more compact.

Q.How often should it be repotted?

A.Repot when the roots have filled the current pot, choosing a time during active growth. It doesn't need frequent repotting — just check root growth periodically and repot as needed.
