Espirea japonesa

Spiraea japonica
Un arbusto caducifolio denso y redondeado originario de Japón y China, cultivado por sus corimbos planos de diminutas flores rosas que cubren el follaje de junio a julio sobre hojas ovaladas y finamente dentadas. Fácil y de bajo mantenimiento a pleno sol, tolera la arcilla, los ciervos, la erosión y las condiciones urbanas. También es un autosiembrador agresivo que ha escapado de los jardines y se ha naturalizado por el este de los EE. UU., donde varios estados la catalogan como invasora.

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.
Now
Zone 6b

Well-suited
2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Well-suited
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.
Well-suited today and still thriving 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.
