Sarracenia rubra subsp. jonesii is a pitcher plant found only in a handful of Appalachian Mountain wetlands in the United States. It resembles a larger version of Sarracenia rubra, sending up slim, upright green pitchers marked with red veining, and in season it produces fragrant reddish-purple flowers. It is listed in CITES Appendix I, and in Japan any sale or transfer in principle requires a registration certificate under the Act on Conservation of Endangered Species. Plants propagated in Japan are also subject to registration, so always confirm that a registration certificate comes with the plant when buying. It's generally considered a plant for intermediate growers, and as a perennial it can be kept going for years through division.

琼斯红瓶子草的基本数据
- 养护难度
- 适合中级者
- 寿命
- 多年生植物（可通过分株长期维持）
- 体型
- 捕虫叶高度43～61厘米，口径约2.8～4.2厘米
- 浇水
- 不施肥（靠捕捉昆虫获得营养）
- 光照与放置
- 在室外光照充足的地方培养。光照不足会导致颜色着色不佳，捕虫叶也会变得柔弱。
- 浇水
- 将盆保持在深约4～6厘米的水中，始终保持浸润，决不干燥。用雨水等矿物含量少的水。
- 基质和换盆
- 基质的基本配方是泥炭与沙以1:1混合。生长良好的植株应每3～4年进行分株换盆。
- 温度与越冬
- 产自山地，耐寒性强，如果充分休眠，即使经受严重霜冻（-7℃）也不会受损。冬季必须在低温下休眠。
- 肥料
- 成熟植株的基质中不施肥。肥料会导致根茎腐烂。置于阳光充足、有昆虫的环境中就能充分生长。
- 病虫害和注意事项
- 华盛顿条约附录I的亚种，国内买卖和转让需要登记证。不要购买没有登记证的植株。
关于琼斯红瓶子草
Sarracenia rubra subsp. jonesii is a carnivorous pitcher plant native to Appalachian mountain wetlands, known for slender red-veined pitchers and raspberry-scented red flowers. A perennial suited to intermediate growers.
开始养护琼斯红瓶子草前需要了解的7件事
1Give It Full Sun
Like other Sarracenias, this plant thrives with as much direct light as possible, whether grown outdoors or on a bright windowsill. Insufficient light tends to mute the red veining on the pitchers and can cause them to grow thin and leggy.
2Keep It in a Water Tray
Because it grows naturally in wetlands, keep the pot standing in a shallow tray of water so the soil stays consistently moist. Letting it dry out, especially during active growth, can weaken the plant.
3Use a Nutrient-Free Mix
Pot it in a mix of sphagnum moss, peat moss, and perlite that contains no added fertilizer. Standard potting soil or fertilized mixes can damage the roots.
4Repot After Dormancy
The best time to repot is right as the plant is waking from dormancy. Lift the root mass with minimal disturbance and move it into fresh mix, choosing a pot roomy enough for its relatively large pitchers to keep spreading.
5Let It Go Dormant in Winter
Coming from a mountain habitat, it's cold-hardy and can overwinter outdoors, and going through a proper dormancy helps it grow well the following year. Cut back on watering somewhat over winter, but avoid letting it dry out completely.
6Enjoy the Spring Bloom
In spring it produces red flowers with a raspberry-like fragrance. Since flowering overlaps with new pitcher growth, cutting the flower stalk early lets the plant put more energy into its pitchers.
7Propagate by Division
As a perennial, it can be maintained indefinitely through division of the clump. When choosing a plant, look for one with clearly defined red veining, minimal damage, and a firm base, which makes it easier to manage going forward.
琼斯红瓶子草的常见问题
- Q.Is this a good plant for beginners?
- A.Sarracenia rubra subsp. jonesii is generally considered better suited to intermediate growers. Once you understand the basics of carnivorous plant care, such as tray watering and winter dormancy, it's manageable to keep long-term.
- Q.Can it be grown indoors?
- A.It can be grown indoors if you can provide strong light and good air circulation, but it's usually easier to give it adequate sun and a proper winter dormancy outdoors. A balcony or similarly open spot tends to work well.
- Q.Does it die back in winter?
- A.The pitchers above ground do deteriorate in winter, but that's part of entering dormancy rather than the plant dying. As a perennial, the plant itself survives and sends up new pitchers again in spring.
- Q.Do I need to feed it insects?
- A.In the wild it catches insects that fall into its pitchers, and plants kept outdoors or near open windows usually catch enough insects on their own. Manual feeding generally isn't necessary.
- Q.How large does it grow?
- A.Based on reference data, the pitchers reach roughly 43-61cm in height with an opening about 2.8-4.2cm across. As it's propagated by division, a mature clump will show multiple pitchers rising together.
