寿命

多年生

体型

野生环境中最高可达5米（盆栽约30～60厘米）

浇水

浇水控制

光照和摆放位置

在阳光充足到半荫处生长。白化型白幽灵对直射日光敏感，应放在明亮的半荫处。

浇水

夏型植物。不喜湿润土壤，需保证排水良好。夏季定期浇水，使土壤不完全干透；冬季减少浇水。

温度和越冬

不耐霜冻。日本园艺图鉴建议耐寒温度约5℃，冬季应在室内明亮处管理。

土壤和换盆

使用排水良好的土壤种植。植株易长高易倒伏，应选择稳定的花盆。

繁殖方法

剪枝扦插繁殖。剪口处流出的乳液需停止后充分干燥再扦插。缀化型和白化型通常通过嫁接到砧木上繁殖。

病虫害和注意事项

剪口处的白色乳液有毒，接触皮肤会引起过敏，进入眼睛会引起严重炎症。修剪和换盆时应戴手套和护目镜，并放置在儿童和宠物无法接触的地方。

关于斑叶麒麟

Euphorbia lactea (mottled spurge) is a cactus-like columnar succulent with paired short spines and white-striped stems. Beginner-friendly at about 30-60 cm in a pot, with forms like White Ghost.

开始养护斑叶麒麟前需要了解的7件事

1. 1Give it plenty of light

   Choose a spot with good sunlight and airflow. From spring to autumn, growing it in a sunny spot outdoors keeps the stems firm and the white striping crisp. Indoors, use a bright window, and rethink the placement if the stems start to stretch thin for lack of light.

2. 2Don't let it dry out fully in summer

   It is a summer grower: in summer, water regularly so the soil never dries out completely, and cut back in winter. It still dislikes soggy soil, so use a fast-draining mix and empty any water that collects in the saucer.

3. 3Fast-draining soil and pot

   A commercial cactus and succulent mix, or akadama blended with pumice or perlite, drains well and suits this plant. As it grows taller it can tip over, so choose a pot with some weight that keeps it stable. Always use a pot with a drainage hole.

4. 4Repot in warm weather

   Repot into a slightly larger pot in spring to early summer, when the roots have filled the current one. After repotting, hold off watering for a few days while root damage settles, then return to normal watering gradually.

5. 5Rainy spells and winter

   It grows in warm weather and can live outdoors from spring to autumn. Long wet spells can cause root rot, so move it under the eaves or another spot out of the rain during the rainy season and autumn downpours. It dislikes cold, so bring it into a bright indoor spot as autumn deepens and keep it on the dry side, watering very sparingly, through winter.

6. 6Mind the white sap

   Cuts or wounds release a milky white sap. It can irritate skin, so wear gloves when handling the plant and rinse thoroughly with water if it touches you. Keep the plant out of reach of pets and small children who might put it in their mouths.

7. 7Choosing a healthy plant

   Look for firm stems with clearly defined white striping, no soft, discolored patches or sunken areas, and a base that does not wobble. A brown, hardened base is often just a sign of age. Crested forms such as Shunpo are sometimes grafted, so it is worth asking the seller.

斑叶麒麟的常见问题

Q.Is Euphorbia lactea a cactus?

A.No. It belongs to the spurge family (genus Euphorbia), and its columnar shape and spines make it easy to mistake for a cactus. Care is similar in that it needs bright light and good drainage, but it differs in that the stems release a white sap.

Q.Can I grow it indoors?

A.Yes, if you have a bright spot such as a sunny window. Too little light makes the stems stretch thin, so avoid keeping it in a dim place, and put it out in the sun on fine days if you can.

Q.Can I cut it back if it gets too big?

A.Yes, and cutting back during the warm growing season helps it recover. Let a cut stem sit for a few days until the sap stops and the cut end dries, then insert it into dry, well-drained soil to root it as a cutting. Wear gloves and keep the sap away from your skin and eyes.

Q.What are White Ghost and Shunpo?

A.White Ghost is a garden form with whitened stems, and Shunpo is a garden form whose stems have crested into a fan shape. Both are enjoyed as forms of Euphorbia lactea, but whitened tissue tends to sunburn easily, so acclimate the plant gradually to strong direct sun.

Q.Why are the stems turning soft?

A.Soft stems often point to root rot from overwatering, poor drainage, or winter cold. Stop watering and watch the plant in a well-ventilated spot, and if the damage keeps spreading, you can cut back to healthy tissue and root it as a cutting.
