More Details

Euphorbia oblongata is the all round best-looking, longest-flowering foliage plant you can find anywhere in the world. It forms the base of 95% of my floral arrangements, and lines most of the beds in my garden at Perch Hill.

You never tire of their brilliant acid-green flowers and bold, strong shapes. It is really a short-lived perennial, but it flowers best in its first year, so we treat it as a hardy annual.

Please note: This is toxic if eaten. It is a skin and eye irritant.

Genus Euphorbia oblongata
Type Short-lived Perennial (Grown as a Hardy Annual)
Common Name Eggleaf spurge, Oblong spurge
Border Position Front, Middle
Soil Type Neutral
Scent Unscented

Sowing, Seeds, Planting Sow under cover in Feb-April and September. Sow direct or plant out in April and August.
Care Tips Cut stems back as they brown to allow room for new growth. Can withstand a touch of frost and can be sown/planted straight into the ground in the autumn and will keep through the winter without protection. In colder areas you may wish to cover seedlings or keep in a cold frame/unheated greenhouse.
Flowering April - December, 16 weeks from spring sowing of seed.
Vase Life 7-10 days. Soak overnight and sear the stems for 30 seconds to stop the sap leaking out. Take care when picking, wear gloves and avoid white sap which can burn.
Harvesting Flower production: 9 months.

Brilliant planted along the border

I bought 10 plants two years ago and they are still going strong after the cold winter lasted year. I left the top foliage on over winter and in March, there were shoots emerging from the base of the plant. So it was easy to prune out the old stems. The plants are all up to full height within a couple of months and blooming beautifully. I’ve ordered more plants to line another border now:)

I bought 5 seedlings last year out of curiosity really as I'd never heard of this plant, although I have other perennial euphorbias in my garden. Last summer the seedlings all did really well and filled out wonderfully, and to my astonishment, as I thought they should be treated as annuals, went through our Yorkshire winter ! Now they're looking fabulous so earlier this year I sent for another five which are doing well too. I am so pleased with them and being shorter than some euphorbias they're great for providing foliage colour in a vase of summer flowers. Plus I think lime green in a garden is always a bonus. Definitely recommended.

easy to grow outdoors

To begin with, I was a bit disappointed at how slow/patchy the germination was: I was starting them off indoors (just a few), and it wasn't a success. So I took the couple that had germinated, and then also sowed other seed direct into the ground in May. We are in Scotland so maybe this is April elsewhere ;) Completely delighted to find that pretty much all the seed I sowed direct outdoors has now sprouted into pretty lime green plants along my borders.

this is the first year I have grown this and will definitely do so again. It looks great in a vase complementing other cut flowers and lasts really well. It also looks good at the front of perennial beds. It has been a little slow to get going so start early!

Love It!

I did order these rather late in the season as seedlings, so they have taken a while to establish & flower, but now they have got going I am so pleased. Lime green is such a great colour anywhere in the garden. I'll be ordering more next year. PS - I've grown mine in pots. They would probably be even better in the ground.
