Why does my milk bush (euphorbia tirucalli) never turn orange or colorful even in full sun as long as I can remember when I planted it 6 years ago? I live in sunny San Diego CA. I see other plants in my area turning into beautiful orange-y color but mine is always deep green. I've researched if there is another variety that never change color, but haven't found one. Anyone? Please let me know, if anyone else has the same non-changing green milk bush like me then I will not wish it to turn a different color anymore. It is planted outside in full sun. Thank you!

I'm not sure but I think Milk Bush (Euphorbia tirucalli) stays mostly green year-round.

Whereas, Pencil Cactus (Euphorbia tirucalli 'Firesticks') is one that has the vivid orange-red color.

Lin is right. Your plant is probably the green form.

Yes, the green plant also gets much bigger than the orange plant. Given time and space and good care, it will grow into a proper tree. Here's an example on the smaller side (they grow 2-3x this big) from the neighborhood.

If and when you prune or propagate this plant, handle with caution. The sap is a potent irritant. Avoid contact with your bare skin (use gloves) and eyes (eyewear) and be aware it comes out under pressure.

Hello All!
Thank you for your answers about my evergreen Euphorbia Tirucalli. So now I know that there is a really a distinction between the milk bush and fire stick euphorbia. I just thought that maybe I water mine more, hah! or I need to put some plant food to make it more colorful. Now I know better. Thanks guys!
