Question: Which one is the most cold-hardy palms in the world, Halimodendron or Rhapidophyllum?

<P0-S0> Chamaerops is a genus of flowering plants in the palm family Arecaceae. <P0-S1>  The only currently fully accepted species is Chamaerops humilis, variously called European fan palm, or the Mediterranean dwarf palm. <P0-S2>  It is one of the most cold-hardy palms used in landscaping in temperate climates. <SEP> <P1-S0>  It is native to the subtropical southeastern United States. <P1-S1>  Endemic populations can be found from coastal southeast South Carolina, southward to Florida and west across the coastal plain of Mississippi and southern Alabama. <P1-S2>  It is one of the most cold-hardy palms in the world, and can be found growing in several areas with warm temperate climates. <P1-S3> Rhapidophyllum hystrix, the needle palm, is a palm, the sole member of the genus Rhapidophyllum. <SEP> <P2-S0>  It is closely related to the genus "Caragana". <P2-S1>  It is native to Russia and southern Asia, but it can be found on other continents where it is an introduced species, and one that is often a noxious weed. <P2-S2>  This is a deciduous spiny shrub sprawling to a few meters in maximum width and up to three meters tall. <P2-S3>  Stems branch from the base and bear clusters of about four leaflets on sharp spurs. <P2-S4>  The ends of branches narrow to spines. <P2-S5> Halimodendron is a monotypic genus of legume containing the single species Halimodendron halodendron, which is known by several common names, including common salt tree and Russian salt tree. <P2-S6>  Flowers also appear at the ends of spurs in clusters of two to four pink pealike blossoms each one to two centimeters wide. <P2-S7>  The fruit is a black woody inflated pod about 2 centimeters long containing legume seeds. <P2-S8>  The plant has a deep and wide root system, with the lateral roots sending up new shoots. <P2-S9>  In this manner the plant forms extensive thickets. <P2-S10>  When introduced to an area of suitable climate, such as California where it is a known weed, it can invade cultivated land and spread relatively quickly. <P2-S11>  It is tolerant of saline soils. <SEP> <P3-S0> The Samadhi Statue is a statue situated at Mahamevnāwa Park in Anuradhapura, Sri Lanka. <P3-S1>  The Buddha is depicted in the position of the "Dhyana Mudra," the posture of meditation associated with his first Enlightenment. <P3-S2>  Whether the Buddha's Enlightenment was the experience technically called samadhi, or some other phenomenon, may depend upon the philosophical allegiance of the believer. <P3-S3>  In the Dhyana Mudra the Buddha sits cross-legged with his upturned palms placed one over the other on his lap. <P3-S4>  This position is universally known throughout the Buddhist world, and this statue is therefore one of the most typical pieces of Buddhist sculpture. <P3-S5>  It is not to be confused with the very similar "Earth-Touching Mudra," which depicts the simple action the Buddha took to fend off the illusions projected by Mara, who was desperate to prevent the Buddha from realizing that his, Mara's, projections, and with them the entire world, are an illusion. <P3-S6>  This statue is 8 feet in height and carved from granite.
