葫蘆豬籠草

葫蘆豬籠草（學名：Nepenthes ventricosa）是菲律賓特有的熱帶食蟲植物。其生長於海拔1000米至2000米的山地森林中。其存在於呂宋島、班乃島和辛布亞島。
其捕蟲籠眾多，可高達20釐米，為白色至紅色。在野外，其捕蟲籠存在硬質平口和軟質斜口兩種類型。硬質平口的捕蟲籠更持久，而具軟質斜口捕蟲籠的植株更耐熱。
葫蘆豬籠草與伯克豬籠草（N. burkei ）和辛布亞島豬籠草（N. sibuyanensis ）之間存在著密切的近緣關係。

**種下類群**
Nepenthes ventricosa f. luteoviridis Y.Fukatsu (1999) nom.nud.

**自然雜交種**
N. alata × N. ventricosa=N. × ventrata

**栽培方法**
葫蘆豬籠草屬於容易栽培的中高地豬籠草，這種豬籠草以其成年植株極為優越的耐寒和耐低空氣溼度性能而被視作是最為耐寒的豬籠草之一，甚至可以抵抗住短期的霜凍。就連許多比它更耐寒的園藝雜交種都是該物種的後代。
略微害怕炎熱環境，在過於炎熱的夏季最好對其進行遮陰。
葫蘆豬籠草的雜交種對環境常常具有卓越的適應力，因此也經常被應用於園藝育種。
