Tout jardinier sait que l&#8217;exposition (soleil, mi-ombre ou ombre) est un des crit\u00e8res \u00e0 prendre en compte pour l&#8217;emplacement des plantes. Ce crit\u00e8re est particuli\u00e8rement important pour le vaste genre des heuch\u00e8res, qui comptent des centaines de cultivars. Tr\u00e8s peu d&#8217;heuch\u00e8res supportent une exposition en plein soleil, surtout si les temp\u00e9ratures sont \u00e9lev\u00e9es en \u00e9t\u00e9. La plupart pr\u00e9f\u00e8rent la mi-ombre. Pour plus de d\u00e9tails je vous renvoie \u00e0 une excellente \u00e9tude conduite en <span id=\"scientific-name\" class=\"subheading\">2012-2014<\/span> par le Mt. Cuba Center aux \u00c9tats-Unis d&#8217;Am\u00e9rique. Voir le rapport ici : <a href=\"https:\/\/mtcubacenter.org\/trials\/heuchera\/\">https:\/\/mtcubacenter.org\/trials\/heuchera\/<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dans ce rapport, 83 cultivars d&#8217;heuch\u00e8res ont \u00e9t\u00e9 \u00e9tudi\u00e9s, et leurs caract\u00e9ristiques soigneusement not\u00e9es, parmi lesquelles la tol\u00e9rance \u00e0 l&#8217;exposition du soleil. On y remarque que les cultivars aux couleurs claires (jaune, vert chartreuse) ne supportent pas du tout le soleil, tandis que d&#8217;autres ne supportent pas plus que quelques heures de soleil par jour. Les feuillages les plus fonc\u00e9s sont les plus tol\u00e9rants.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft\"><a href=\"http:\/\/www.rezeau.org\/wp-garden\/wp-content\/uploads\/Heuchera-Chocolate-Ruffles-06-05-2020.jpg\" rel=\"lightbox[14168]\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"200\" src=\"http:\/\/www.rezeau.org\/wp-garden\/wp-content\/uploads\/Heuchera-Chocolate-Ruffles-06-05-2020-300x200.jpg\" alt=\"Boutures (ombre) \u00e0 gauche et pleine terre (soleil) \u00e0 droite !\" class=\"wp-image-14170\" srcset=\"https:\/\/www.rezeau.org\/wp-garden\/wp-content\/uploads\/Heuchera-Chocolate-Ruffles-06-05-2020-300x200.jpg 300w, https:\/\/www.rezeau.org\/wp-garden\/wp-content\/uploads\/Heuchera-Chocolate-Ruffles-06-05-2020-768x512.jpg 768w, https:\/\/www.rezeau.org\/wp-garden\/wp-content\/uploads\/Heuchera-Chocolate-Ruffles-06-05-2020.jpg 800w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption><em>Heuchera<\/em> &#8216;Chocolate Ruffles&#8217;<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Un exemple int\u00e9ressant de l&#8217;influence de l&#8217;exposition s&#8217;est produit au jardin.
