Euphorbia

I find E. cyparassias to be a very attractive plant... so colourful in spring - as your picture shows - burgundy with a splash of yellow flowers, then turning to a feathery-textured green later on.
Mine would be starting to bloom now... if I hadn't dug them out last weekend!  :-[  (Unfortunately, it is quite invasive here, and was starting to scare me with its 10' diameter spread, and fine roots!  It seems to love to come up in the crowns of other plants.)  I don't fool myself that I actually got it all in one effort... it will be coming up for years, and I may put some in a pot to continue to enjoy.  It is not so spready there, though, I think?

1, 2) Euphorbia cyparassias

Here's another beautiful euphorbia, E. griffithii 'Fireglow'.  Right now, the fiery-red shoots are just poking out of the ground, so these photos are from later in the season - wonderful fall colour!

3, 4, 5) Euphorbia griffithii 'Fireglow'

Trond, you must be able to grow a lot of the more tender ones that I always wish I could grow here!

Lori,
I have to admit E. cyparassias is rather invasive so I have put it between the road and some shrubs hoping to contain it there.
I grow the 'Fireglow' too and a few others but I have not tried all I wish - it is so many plants waiting to be tested in my garden!

I have what is suppose to be cyparassias but mine is plain green from the start..not that attractive burgundy...and it runs like crazy...I have torn out most of it.

Here are a couple of forms of the justifiably popular Euphorbia polychroma, a very well-behaved species, only seeding around a bit...  This will be a fairly common sight in gardens around here soon, although they are just emerging now.
1) Euphorbia polychroma
2, 3) And an attractive dark-foliaged cultivar, Euphorbia polychroma 'Bonfire'

Here is Euphorbia capitulata, definitely a rock garden-sized species, that is native to Albania, the former Yugoslavia and Greece.
(PS   I don't claim to be growing it terribly well, though I am impressed that it's been hardy over a few years now.  I'll try to remember to post a better photo later (to help you all forget this one!))

I believe this to be a most interesting thread because it is useful to discuss genera like Euphorbia, one containing many attractive species, but some of the most notoriously aggressive ones too.  So, I am taking notes here, for the ones that seem well behaved compared to others.  I do not have any Euphorbia in the garden currently, but polychroma 'Bonfire' and E. griffithii 'Fireglow' are now on my list. :D

I can recommend both! (Not flowering yet here.) The 'Fireglow' runs a little and the runners are deep in the soil and tough to cut.
