Euphorbia xanti

#1

Post by Geoff »

love/hate this species... makes a very attractive bush when in flower, but is incredibly invasive (this is the 'mother of thousands of the Euphorbia genus)... though here in Acton I would love if it were invasive... sadly not very cold hardy (down to about 25F is all). This is a twiggy, offsetting, and fairly rapid growing plant that is very adept at shooting its seed dozens of feet from the mother plant. Any garden with this growing well will soon be in need of 'weeding' of this plant

not so ornamental when not in full flower... and can get messy-weedy, like here in the Huntington Gardens

Yes, very self-seeding here in LA. Nice plant though, the flowers are really colorful. Not too hard to pull seedlings, though gloves are advisable.

Agree on the love/hate sentiment. I grow it here in Mesa and I like the plant especially when in flower. Surprisingly drought tolerant - just drops its leaves - is on the same watering regime as the Agaves, Aloes, and Cacti. The weeding has started for me, trying to keep it from crowding out a Tacoma stans 'Fireballs' and keep it from spreading among the Agaves, Aloes, and Cacti - that is where the dislike comes from, grows tall and dense enough to form a hedge if you let it.

As Viegener writes: Easy to weed, and also takes pruning without issue, but beware the sap, it has been pretty much harmless to me, but it affects everyone differently.
It is what it is!

Plant foliage in late fall/early winter making it harder to realize it's a Euphorbia

The minute you break a stem & see the white sap you know it's a euphorbia. I'm slowly clearing all of them from my yard. They end up looking too scrappy.
