Hippeastrum pardinum

Native range
Hippeastrum pardinum is native to Bolivia and Peru.

Description

Hippeastrum pardinum is a mudium species. A 5~6 CM mature bulb has the ability of blooming. It is
The flower stem is about 30CM long. There are red spots on the petals. The substrate of the petals is totally white or very little green according to climate or individual difference.

It stops growing but the old leaves do not fade. The new leaves start to grow after the flower blooms.

Florescence
During early spring to late spring in Taiwan.

Cultivation hint

The plants prefer a sunny to half-shady situation on moderately moist soil. The substrate should be sandy-loamy or gritty-loamy soil.
I plant it alfresco. The leaves were burned by violent sunshine. I do not move it inside the house when it rains. The growing state is good.

The arrangement of the stamens is interesting.

Hippeastrum iguazanum seedlings

I bought from Hippeastrum iguazanum seeds a foreign friend in gardening. They are very expensive. I wish they can grow up successfully.
 

Hippeastrum mandonii rots

We should take much care of planting a H. mandonii. The main soil requirement is excellent drainage. And it is not good to give too much fertilizer.
I gave almost the same quantity of fertilizer to many species of native Hippeastrum plants. But only this species bulb split as the picture. If the temperature is too high in summer, bacteria attack the splitting part and then cause rot. Finally some insects grow and eat the rotting part. The situation becomes worse and worse.
Therefor there are some points in planting this species
a.Keep the soil dry
b.Do not give too much fertilizer
c.Put the pot in cool place in summer


When you find that the bulb stops growing in growth period or something abnormal for leaves, for example, some leaves dry up or hang down, it means something happens. You should dig the bulb out and check if it is OK. I saw these symptoms for some days but I am busy and do not check the bulb. Finally the situation gets worse.
I am trying to save it. Maybe I should do notch breeding.

Hippeastrum mandonii creeping stem

Hippeastrums  have two usual ways to propagate. They propagate themselves by seeds and offsets.Some primitive species has creeping stem to propagate themselves. It is different from Griffina espiritensis. Griffina espiritensis grows small bulbs from a random point of a root. Hippeastrum mandonii grows a creeping stem which looks like a root from the bottom of the bulb. And then the creeping stem develops a small bulb at the end. When the small bulb forms well, the bulb starts to leaf. The bulb will root when it detects humidity and it can absorb water and nutrition. Finally, it becames an indivual plant..

primitive Hippeastrum seeds

I got some primitive Hippeastrum seeds from a friend in South America. There are only 2~3 seeds each species and the situation is not very good. I wish then can germinate successfully.

Hippeastrum angustifolium
Hippeastrum breviflorum
Hippeastrum neopardinum
Hippeastrum pardinum
Hippeastrum stylosum

Hippeastrum puniceum

他以前也叫做H. equestere。成熟植株高度大約30公分，種球3-4公分即可開花。是小型品種。
It is identified by an earlier name, H. equestere. A ripe plant is about 30CM high and a bulb can flower when it reach 3-4CM in diameter. It is a little species.

栽培重點 Cultivation hint
該品種在原生地分布頗廣，其中在西印度群島屬於熱帶季風氣候，最熱月均高溫可達30度以上，最高月均雨量也達200MM，氣候環境和台灣差不多，所以在台灣可容易栽培。
This species distributes over the central America. In the West Indies, for example, the average high temperature in the hottest month is up to 30°C, and the highest rainfall is about 200MM in July or August in summer. The climate is similar to Taiwan, then it is easy to cultivate in Taiwan.

特別的是在花心。綠色和橘色涇渭分明啊...
The boundry between the green and the red in the center of the flower is very clear.

網路上資料意外的少。他真的是原生孤嗎??
To my surprise, the data is very scarce on web. Is it really a primitive species?

Hippeastrum nelsonii

原生地 Native range
Hippeastrum nelsonii原生地在南美洲波利維亞拉巴斯的熱帶山地。拉巴斯海拔3660公尺，靠近赤道氣候穩定。最熱月均高溫約14度C，最冷低月均低溫約-2度C。最高雨量在1月，約100多公厘。
Hippeastrum nelsonii is native to La Paz, Bolivia, in South America. It likes to grow in tropical mountain. La Paz is located at an elevation of 3,660 meters above sea level, and the climate is stable. The average high temperature in the hottest month is 14°C, and the average low temperature in the coldest month is -2°C. The highest rainfall is about 100mm in January.

株高約40~50公分，花梗大約高30~40公分。在原生地全年生長不休眠。在台灣嚴冬時停止生長一至兩個月。嚴冬過後初春通常開始生長伴隨著抽出花梗。
The plant is around 40~50CM tall, and the peduncle is around 30~40CM tall. It is evergreen in the habitat, and takes no rest period. But in Taiwan it takes rest for 1~2 months in the severe winter. After the severe winter comes the early spring. It starts to leaf out and then grow the flower stalk soon.
花期  Florescence
台灣約農曆年後初春
Early spring in Taiwan.
栽培重點  Cultivation hint
需要極通氣的介質。在台灣栽培最熱月均高溫可達32度C，最冷月均低溫13度C。最高雨量7月約300公釐。
我都放置戶外全日照，颱風來時才會收入室內。所以這品種是耐熱耐濕的品種，很適合在台灣栽培。

It requires highly aerated soil.

Hippeastrum stylosum

非常難照顧的原生孤挺Hippeastrum stylosum。用培養土混合其他介質種植得到水傷，之後便住在3吋方盆用赤玉土種植已經半年，才開始長葉。這品種在台灣可能很不適應悶熱環境。

Hippeastrum blumenavium

超小型原生孤挺花。
以前曾被歸類於Eithea blumenavia和Griffiniopsis blumenavium，後來歸於Hippeastrum屬。
