Comments:  Euphorbia milli or Crown of Thorns or Christ Plant or Siamese Lucky Plant is an attractive low-growing succulent shrub with a straight stem and small showy flowers. The stem has very dense thorns which helps the plant to climb.  In its condusive environment, these thorny stems can reach 5' tall.  Euphorbia milli is popularly grown as an indoor house plant in colder areas.  This is an interesting plant to grow.  I have the red Crown of Thorns growing in a pot and would love to add other colors,  the white and the pink to my collection.
