A gardener?s first tendency when you mention Euphorbias might evoke visions of Poinsettias, Crown of Thorns or an old favorite, Cushion Spurge. The family of Euphorbias I'm passionate about is commonly known as 'Shrubby Spurges'. With recent developments in breeding efforts, these plants have attained new heights and all I can say is WOW! The new palette of colors and textures now available offers enticing selections to lure you in?and I?m hooked!

Shrubby Spurges are members of the vast family of Euphorbiaceae and received their common name from the fact that their poisonous sap was once used for its purgative qualities. The milky, white sap that bleeds from the plant when the stems are cut or wounded may cause a serious rash for those with sensitive skin or latex allergies, so always use caution when handling these plants.
These Spurges are outstanding choices for the landscape. Their only requirement is excellent drainage. They even tolerate dry, poor soils. Light requirements vary, most will perform admirably in full sun or partial shade. There are a few Euphorbias such as wood spurge, (Euphorbia amygdaloides) which actually prefer deep shade and create excellent groundcovers. Little, if any, maintenance is necessary with Euphorbias. If the plants become 'leggy', a hard pruning (cutting to within 3 to 6 inches from the ground) will result in a much denser, tightly branched, symmetrical plant and can be done any time of the year.
We’ve had several hardy Euphorbias in our gardens over the years and I've always been fond of those with a 'shrubby' form and especially impressed with their vigorous habit. New cultivars now provide more choices for our gardens and I am rapidly developing an uncontrollable desire to plant more!
I wasn't disappointed; by late spring I was rewarded with a stunning display of handsome foliage.
The arrival of their unique floral display of peculiar 'blooms' in spring and continuing through early summer created yet another attractive highlight in the gardens.
But wait there's more!! As the season progressed, the arrival of frosty temperatures sets the stage for their final performance of the season as their evergreen foliage develops dramatic changes. With each passing day the colors continue to intensify and by December they absolutely glow in the garden! These plants will surely provide never-ending gratification for me in the garden over the long winter.
I'm a satisfied gardener - Euphorbias were an outstanding choice for this garden!
Another member of the Euphorbia family I've found difficult to resist is Euphorbia cotinifolia (Zone 9). This species isn't hardy for our Zone 6 gardens, however it makes a fantastic container plant! I've been successful for three years, bringing the plant inside when the temperatures begin to fall below freezing. Its tremendous growth demanded a larger pot this year, and the shrubby habit was begging for a disguise to conceal its "bare legs." I couldn't refrain from using 'Helena's Blush' once again - the striking variegated foliage was a perfect companion to complement the glowing burgundy color of this Euphorbia.
What more could this crazed Euphorbia enthusiast ask for? What else? More Euphorbias! If my "untamed passion" has persuaded you to add Euphorbias to your garden, take a look at a few of the exciting new selections I'll be considering for planting in the gardens in 2008!
