瑞麒麟

瑞麒麟的基本資料

栽培難度

適合新手

壽命

多年生。經過漫長的年月發展成圓柱狀的大型植株

體型

高度最大2公尺・寬度30公分（原生地）

澆水

肥料需求少（換盆時施用少量緩效性肥料）

日照・擺放位置

在陽光充足的地方養護。在遮光後光線充足的半陰處養護時，植株顏色變深綠。長期放在陰暗處後突然受到強光照射會導致曬傷。

澆水

夏型種。雖然是抗根腐的強健品種，但應使用排水良好的介質，待介質乾燥後再澆水。冬季減少澆水，保持較乾的狀態。

溫度・越冬

成株可耐-4℃左右的低溫。國內資料以5℃作為耐寒目標溫度；盆栽應避免冬季凍害和霜凍。

介質・換盆

用排水良好的仙人掌專用介質種植。本種生長較大，根部長滿後需換用更大的花盆。

繁殖方法

因不能自花授粉，需通過2株以上交配的實生進行繁殖。實生株間的星點花紋和刺的生長方式各不相同。

病蟲害・注意事項

稜線上的刺堅硬且尖銳，換盆時應戴厚手套或用報紙包裹以防割傷。

關於瑞麒麟

Hannya (Astrophytum) is the largest of its genus, a beginner-friendly columnar cactus with white scales and yellow summer flowers. Get tips on light, watering, soil and repotting.

開始照料瑞麒麟前需要了解的7件事

1. 1Sun and Airflow

   Bright sun and good airflow are the basics for keeping Hannya healthy. With too little light the plant tends to stretch thin, so give it the sunniest spot you have. When moving it outdoors, introduce it to strong sun gradually to avoid sun damage.

2. 2Water When Dry

   During the growing season, water thoroughly, but only after the soil has dried out completely. Constantly damp soil can lead to root rot, so never leave water standing in the saucer. To keep the white scale patterns looking clean, water around the base rather than over the top of the plant.

3. 3Fast-Draining Soil

   A fast-draining cactus and succulent mix suits Hannya well. Adding pumice or coarse sand to a ready-made cactus soil improves drainage even further. As the column grows taller its center of gravity rises, so a sturdy, stable pot helps keep it from tipping.

4. 4Repotting Tips

   When the roots have filled the pot, repot into a container one size larger at the start of the growing season. The spines are sharp, so wrap the plant in thick gloves or folded newspaper while you work. After repotting, hold off on watering for a while so the roots can settle.

5. 5Seasonal Care

   From spring to autumn, keep it in a sunny spot, and make sure it gets good airflow in summer so the plant does not stay stuffy. In winter, water much more sparingly and keep it where it will not freeze. Steady, strong light through the year also helps you enjoy its summer blooms.

6. 6Choosing a Plant

   Look for a plant with a firm base and no discoloration or soft spots. Check that the spines and ribs are undamaged and that the white scales cover the body. Review the photos and description on the listing page to confirm the plant's size and condition.

7. 7Plan for Its Size

   Hannya is the largest plant in the Astrophytum genus, reaching up to 2 m tall and 30 cm wide in its native habitat. Growth speed varies with conditions, but as a perennial it slowly develops into a large columnar plant over many years. Think about where it will live and what pot it will need in the future before bringing one home.

瑞麒麟的常見問題

Q.Can beginners grow Hannya?

A.Yes, it is rated as beginner-friendly. Provide good sun, airflow and drainage, and avoid overwatering, and you can enjoy this perennial for many years.

Q.How big does Hannya get?

A.In its native habitat it can reach up to 2 m in height and about 30 cm in width. Growth in a pot depends on the conditions, but it slowly becomes a large columnar plant over many years.

Q.How often should I water it?

A.Rather than following a fixed schedule, water only once the soil has dried out completely. Drying speed changes with the season and location, so water especially sparingly in winter.

Q.Can I grow it indoors?

A.Yes, if you have a bright spot such as a sunny windowsill. Too little light makes the plant stretch, so ventilate the room regularly to keep the air moving.

Q.When does Hannya bloom?

A.It produces yellow flowers in summer. Weak light or a stressed plant can reduce flowering, so keep it in a sunny position throughout the year.
