Real grower update · Huertas Urbanas seeds
A real cultivation update from a professional nursery grower: healthy
Orange Guabiroba plants, identified as
Campomanesia xanthocarpa, growing from seeds originally supplied by Huertas Urbanas.
“The Campomanesia are about 5 ft tall and growing in the ground.”
— Grower update, 2026
One of the most rewarding parts of working with rare fruit seeds is hearing back years later from growers who actually planted, cared for and evaluated the material. This update comes from a professional nursery grower who purchased several native South American species from Huertas Urbanas in 2020.
Among that order were seeds of Campomanesia xanthocarpa, sold by us under the common / collector name Orange Guabiroba. The grower now reports five plants established in the ground, approximately five feet tall, healthy, and not yet fruiting.
Growing in real nursery conditions
According to the grower, the plants are growing in a low sandy area without special soil amendments. The site alternates between very dry periods and occasional short flooding, with water reaching roughly two inches for up to about three days.
He also reports minimal fertilization and no irrigation, with the plants growing cleanly and without disease problems in his conditions. This is exactly the kind of long-term, real-world feedback that helps us understand which species deserve wider trial by serious growers.
A note on cold, drought and flooding
The grower also reported that the plants came through a cold event near 22 °F / −5.6 °C with strong winds, without visible damage in his location. That is an encouraging observation, but it should be read carefully: this is one grower’s experience, in one site, with established plants and local conditions that may not match other gardens.
We do not present this as a guarantee of cold hardiness, drought tolerance, flood tolerance or general adaptability. Rare fruit plants can behave very differently depending on plant age, soil, drainage, wind exposure, humidity, nutrition, root development and duration of the stress event.
Why this update matters
Orange Guabiroba is not just a name in a seed list anymore. It is now represented by living, seed-grown plants in a real collection, growing under non-ideal nursery conditions and developing into established trees. That is the kind of practical evidence rare fruit growers need.
From seed to living collection
At Huertas Urbanas, many of the species we distribute are rare, poorly documented in cultivation, or only just beginning to circulate among collectors outside their native range. Every successful grow-out helps build a better picture of what these plants can become.
We are especially happy to see Orange Guabiroba developing into strong, attractive plants with beautiful foliage. We hope to continue documenting more real grower updates like this — including successes, partial results and failures — so that collectors and growers can make better decisions.
