If you don’t prune it, it produces multiple trunks with slender stems.
It has a moderate growth rate.
The simple green leaves grow in an alternating arrangement along the stems.

The star-shaped 1″ inch wide deep red flowers with yellow stamens are held in branched clusters on 4″ inch long stalks around glossy green foliage.
Light & Temperature
Like its cousin Jatropha podagrica (buddha belly plant) Integerrima grows best in USDA hardiness zones 10 and 11.
A full sun setting will produce the most flowers.
It’s a good idea to cover the plant if cold temperatures are expected.
Integerrima performs best in full sun frost-free locations but will grow in partial shade.
Watering & Feeding
This plant’s both maintenance and drought tolerant.
Water regularly throughout the growing season and less during the dormant season.
Provide a weak dilution of general-purpose houseplant fertilizer during the growing season.
Soil & Transplanting
Firecracker Jatropha is easy to care for once it’s established.
It’s highly tolerant of a wide range of soil pH levels so long as the soil is well drained.
Plant young plants in well-draining soil, this plant is not tolerant of salt.
It’s not a good choice for the seaside or beach setting.
Grooming & Maintenance
Prune Spicy Jatropha to control its growth and guide the form it takes.
If you allow it to grow free-form, it will become an interesting, wide bush or multi-trunk tree.
How To Propagate Spicy Jatropha
Spicy Jatropha propagates from seed or cuttings.
To grow from seed:
- Prepare the seeds by soaking them in warm water for eight hours before planting.
- Plant directly into the soil outdoors in a sunny location.
- The soil should consist of equal parts of sand, garden soil, and aged manure.
- Don’t bury the seed deeply, instead press it into the surface of the amended soil.
- Water frequently (two times daily) for the first week.
- Shoots should appear within six days.
- Reduce watering to once daily until the seedlings are ready to be transplanted.
This should take a couple of months.
To plant from cuttings:
- You’ll need a mature tree producing shoots.
- Cutting should be taken from the base of the tree, be at least 18″ inches long and have a minimum of four nodes.
- Put the cutting into a container of damp sawdust, coco core or peat moss in a sheltered setting such as a planting tunnel or greenhouse.
- You must keep the cutting warm between 77° – 86° degrees Fahrenheit (25° C – 30° C) with a high level of humidity 70% to 90%.
- Keep the planting substrate moist but not saturated.
The cutting should begin developing roots within 7 – 10 days.
