| History | Alta was discovered as a chance seedling of Hasse, the most well known columnar southern magnolia variety. This magnolia species is native to North America where it is commonly called bull bay. It's range extends across the south from North Carolina to Texas and south to Florida. It was introduced to Europe in 1734 and later classified by Linnaeus into the genus he named after Pierre Magnol, 1638-1715, a botanist of Montpelier, France. By 1863 a number of garden varieties including lanceolata and the Edgmouth magnolia had been developed but proved too frost tender for their colder winters. |
| Lore | Southern magnolia is the state flower of Louisiana and Mississippi. It grows in mixed stands of forest in areas of well drained but evenly moist soils and accessible water table. It is also considered the largest native flower in North America. |
