Positive KatG On May 12, 2009, KatG from Port Charlotte, FL (Zone 10a) wrote:

This is the largest of the Crown of Thorn plants with 1" orchid red blooms and large stiff canes that create a somewhat more upright mature specimen. A native of Madagascar, it is a succulent, with thick, fleshy stems adapted for water storage. The stems are 5-7 sided, greyish-brown, branched & up to 2-3' in height, with many prominent, grey 1" spines. The leaves tend to be obovate (wider near the tip), up to 6". They are spirally arranged, have smooth margins, & vary from bright green to grey-green. Foliage is present only on new growth. This is a lovely plant that blooms all year round.
