Re: [SHADEGARDENS] Questions on Species--Euphorbia and Euonymus

Sombreros,

Hinkley wrote about Euphorbias last year for Martha Stewart's Magazine. It
is the only time my wife has ever purchased it. Of Euphorbia dulcis
'Chamaeleon' he says, " Zone 5 Eagerly self-sows with seedlings coming true
but best to shear to the ground after blossoming ceases for a renewal of
foliage without the hassle of excess seeding. A plant that is here for good
(whether you like it or not.)" My wife considers this plant a weed as it
seems to spring up everywhere, including our front garden, even though we
planted it in one spot in the back garden. Even more of a weed but far more
shade tolerant (it grows in the darkest spot in my garden with Arisaema
ringens, Hosta minors and some ferns is Euphorbia amygdaloides var. robbiae
(zone 6 according to Hinkley). It also grows under my Thuja plicata.
According to Hinkley is the only plant that put in a combative position with
a Thuja would come out on top. It is very definitely drought tolerant.

My favourite weed (and it will grow almost anywhere ) is the tall and
stately (!) Macleaya microcarpa  (zone 5, 6ft). I simply take out the plants
I don't want when they grow in the spring and give to friends and enemies.
If you want to get even with a neighbor sow seed from this plant in their
garden. They will think they have been invaded by plants from Mars. Although
they won't die when transplanted in the summer they will die back ( I tried
it.) This is the plant for back of the border height with Aconitum in shade
and part shade.

Alex Zone 7/8 but sometimes 6.
