The Magnolia genus has about 210 flowering plant species and is named after a French botanist Pierre Magnol. This flower is native to Asia as well as North, Central and South America and the West Indies. The colours range from pinkish white to purplish white. These beautiful flowers bloom from late Winter to early Spring.
The top two paintings above are my paintings of Magnolia flowers. The one on the left (2005) tries to capture the purplish colour and the one on the right (2014) is a minimalist free form depiction of the pale pink type of Magnolia with distinctive petal formation - similar to the photo on the right.

Below on the left is another photo showing the distinctive petal shape and colour of the Magnolia. The painting on the right is by Georgia O'Keeffe (1932) "The White Flower" showing her depiction of the Magnolia flower.
