Seringat des jardins

Philadelphus coronarius
Un grand arbuste caduc vigoureux à multi-tiges, cultivé avant tout pour ses fleurs d'un blanc pur intensément parfumées, qui s'ouvrent en grappes en coupe à la fin du printemps ou au début de l'été et exhalent un riche parfum très proche de la fleur d'oranger. Originaire du sud-est de l'Europe et de la région du Caucase (et non d'Amérique du Nord), il forme un monticule arqué, dense et ovale de 10-12 feet de hauteur et compte parmi les arbustes parfumés à l'ancienne les plus fiables pour le plein soleil à la mi-ombre — facile, résistant au froid et peu exigeant une fois établi, même si son spectacle est une unique et glorieuse explosion de plusieurs semaines plutôt qu'une longue saison.

Les abeilles travaillent intensément les fleurs ouvertes et accessibles pour le nectar et le pollen durant l'explosion de la fin du printemps, ce qui fait de l'arbuste un attrait fort — quoique bref — pour les pollinisateurs.

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
USDA
Published baseline for this location from 1991-2020.

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.
