These Crown of Thorn spurges come in quite a range of colors. This one is Yellow.
Euphorbia milii “Dwarf Yellow”
We have a lot of new vigorous growth right now since we have had a very mild winter. It’s sunny and warm most days. There’s been no cloudy rainy days at all. It’s like an early spring! And the plants are going nutso for the sunshine. Maybe they’ll be caught in mid growth if winter ever does come and then that would be a bad thing for the plants. They could get damaged.
And just for the fun of it, a Salmon colored one too!
(I like the yellow one better. Less showy.)
