The palm has become a characteristic sight along boulevards and promenades in places such as California and the Mediterranean, where its elegant silhouette often towers over the surrounding vegetation.\u003c\/p\u003e\n\u003cp\u003eThe species originates from northwestern Mexico, particularly the southern and central parts of the Baja California peninsula. Here, it grows naturally in dry and hot areas, but typically in locations with access to water, such as in canyons, near springs, and along seasonal streams. Although the palm is adapted to a dry climate, it therefore requires regular access to moisture to develop optimally.\u003c\/p\u003e\n\u003cp\u003eUnder good conditions, \u003cem\u003eWashingtonia robusta\u003c\/em\u003e can reach 20-25 meters in height or more. It develops a single, relatively narrow trunk that is often noticeably wider near the base in older specimens. The large fan leaves sit on long petioles with sharp spines along the edges. The leaves have fine, thread-like fibers along the segments, but usually fewer than in the closely related \u003ca href=\"https:\/\/www.apieceofnature.dk\/products\/washingtonia-filifera-5-stk\" title=\"California fan palm (Washingtonia filifera) | seeds\"\u003e\u003cem\u003eWashingtonia filifera\u003c\/em\u003e\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eA special feature of the Mexican fan palm is that the old, withered leaves often remain attached to the trunk, forming a dense, downward-hanging layer that can resemble a skirt. This is especially seen in palms where the old leaves are not removed and is a characteristic trait of naturally growing specimens.\u003c\/p\u003e\n\u003cp\u003eThe Mexican fan palm is closely related to the \u003ca href=\"https:\/\/www.apieceofnature.dk\/products\/washingtonia-filifera-5-stk\" title=\"California fan palm (Washingtonia filifera) | seeds\"\u003eCalifornia fan palm (\u003cem\u003eWashingtonia filifera\u003c\/em\u003e)\u003c\/a\u003e, but the two differ in several interesting ways. \u003cem\u003eWashingtonia filifera\u003c\/em\u003e normally develops a significantly thicker trunk and has more characteristic white threads along the leaf segments. \u003cem\u003eWashingtonia robusta\u003c\/em\u003e, on the other hand, is more slender and often grows taller.

Larger, established plants can, under favorable conditions, survive temperatures around -5 °C, but leaf damage can occur even at milder frost. The combination of cold and winter humidity is particularly problematic.\u003c\/p\u003e\n\u003cp\u003eIn Danish conditions, cultivation in a pot with light and frost-free overwintering is the safest solution. The palm can be kept outdoors on a sunny terrace during the summer and moved to a sheltered place before the frost sets in.
