Euphorbia obesa<\/em><\/h2>\nIf you\u2019re a succulent fan, you\u2019ll want to get to know the baseball plant, Euphorbia obesa<\/em>.<\/p>\nAs the common name suggests, this plant resembles the signature object of America\u2019s favorite pastime \u2013 the baseball, with a few botanical embellishments.<\/p>\n
Also called sea urchin plant for its resemblance to the marine creature, this species is native to the Cape Province region of South Africa, particularly the Great Karoo semi-arid desert basin.<\/p>\n

But Mother Nature didn\u2019t just endow the smooth, green globe with function.<\/p>\n
The vertical ridges resemble stitches, intersecting horizontal pinkish-purple markings that show best in full sun, for a tartan-like appearance. And it\u2019s topped off with a crown of tiny greenish-yellow springtime blossoms.<\/p>\n
The flowers are nondescript but unique because they may be male, with pollen-coated anthers, or female, with stigmas.<\/p>\n
And while rare, a single plant may have both male and female flowers, and the gender may change over the years.<\/p>\n
Our guide to growing euphorbia<\/a><\/strong> provides an overview of the genus. This article focuses on the unique characteristics of E. obesa<\/em>.<\/p>\nHere\u2019s what we\u2019ll cover:<\/p>\n
The baseball plant has a taproot and grows a single globe. As it ages, the stem elongates into an egg-shaped or cylindrical column.<\/p>\n
Mature dimensions are six to eight inches tall with a spread of three to four inches. Brown, bark-like \u201ccork\u201d at the base is a natural part of the maturation process.<\/p>\n
