Kumquat redondo
Fortunella japonica
Un pequeño árbol o arbusto cítrico perennifolio, denso y redondeado (8-15 feet), cultivado por sus diminutos frutos anaranjados de forma oval a redonda que se comen enteros, con piel y todo — la cáscara dulce y fragante contrasta con la pulpa interior ácida, y ahí está toda la gracia del fruto. Entre los más resistentes al frío de los parientes de los cítricos, soporta el frío breve mejor que la mayoría de los cítricos (aproximadamente hasta la zona USDA 8b), pero aun así es sensible a las heladas y se cultiva mucho en macetones e invernaderos allí donde los inviernos son fríos. Originario del sur de China, no de Norteamérica. Tenga en cuenta que el nombre botánico aceptado es ahora Citrus japonica; Fortunella japonica es el sinónimo de uso extendido.

Cold hardiness
Future
These values are location-based: this location's current hardiness is the baseline, and the 2050 value is a projected future climate for this same location.

Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Won't grow here
In plain terms: This location is in Zone 6b today. Its hardiness profile is cold winters, and coldest nights are typically around -3°F. By 2050, the projected hardiness zone is Zone 7a based on SSP3-7.0 (regional rivalry). That is a +0.5-zone shift from Zone 6b to Zone 7a by 2050.
✕
Out of range today and still out of range in 2050.
Heat tolerance
Future
Heat tolerance values are location-based too: heat days today are observed at this site, and the 2050 value projects this same location under a future climate.
