Mystery Plant, or Weed? Cypress spurge, Euphorbia cyparissias


Hi! I am hoping someone there can tell me what the attached plant or weed is. It grows around my parents’ headstone in a southern Ontario cemetery, part sun part shade. I don’t see it elsewhere in the cemetery which kind of makes me think it was planted and is therefore not a weed. It’s about 10-12″ high, is slowly spreading, and is a perennial. It has tiny flowers, 1/4″ to 1/2″ across, in kind of a mix of pink, pale green tending to pale yellow. The leaves are soft and needle-shaped, although they look like an evergreen needle they’re soft. I would be very grateful if you’re able to tell me what this is, and any information about it. Thank you very much in advance, and also thank you to whoever replied with such great, detailled information to my earlier question about a vine to grow up a Toronto Hydro pole. Master Gardeners ROCK!!


Thank you for contacting Toronto Master Gardeners with your challenging question.

You’re right the plant on the picture is a perennial. Euphorbia cyparissias, commonly called cypress spurge grows best in dry, well-drained soils in full sun. For more information on caring for your Cypress spruge, please visit the following site:
