This larch stands out for its \u201cfour-season conifer\u201d behavior: soft foliage in spring, a light green mass in summer, then a luminous yellow late-season display. It is well suited to cold conditions and sites that remain moderately moist. In climates that are too hot and humid in summer, it performs much less satisfactorily.<\/p>\n
Spring\u2013summer<\/strong> : bright green needles (in clusters on short shoots).<\/p>\n<\/li>\n Autumn<\/strong> : yellow (sometimes yellow-orange) before needles fall.<\/p>\n<\/li>\n Winter<\/strong> : bare silhouette, graphic twigs and persistent cones.<\/p>\n<\/li>\n<\/ul>\n When young, a conical habit with rather horizontal branches; with age, the tree can become broader and more \u201csculptural\u201d. Moderate to good vigor under suitable conditions (moist soil, non-scorching summers). Young shoots are often described as tawny-brown and hairy, and cones as slightly larger than in the typical form.<\/p>\n Indicative ranges cited for cultivation:<\/p>\n about 12 to 27 m tall<\/p>\n<\/li>\n 4.5 to 9 m spread<\/p>\n<\/li>\n in the wild, some larches in the gmelinii group can exceed these figures depending on site. gmelinii<\/em> peuvent d\u00e9passer ces valeurs selon station.<\/p>\n<\/li>\n<\/ul>\n Full sun (tolerates light partial shade, but avoid dense shade). Choose an open, airy position, without excessive summer heat.<\/p>\n A Northeast Asian taxon, native notably to Russia (Primorye \/ Russian Far East), North Korea, and parts of Northeast China (Manchuria; provinces vary by source). It is sometimes treated not as a variety but as a distinct species: Larix olgensis. Larix gmelinii var. olgensis (Olga larch \/ \u201cOlga Bay larch\u201d) is a deciduous conifer: it carries green needles in spring and summer, then turns a beautiful yellow in autumn before shedding. Very hardy, it thrives especially in climates with cool summers and cold winters. Its young conical shape becomes broader and more expressive with age, making it an excellent architectural tree for large gardens and parks, in soil that stays moist but well-drained.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"Larix gmelinii var. olgensis (Larix olgensis) | M\u00e9l\u00e8ze caduc tr\u00e8s rustique, automne jaune","_seopress_titles_desc":"Larix gmelinii var. olgensis (syn.
