Yes, helleborus, I've found eryngium x olivieranum to be the bluest of the lot - one visitor to our garden described them as looking as though they'd been dipped in ink. Some people find the intensity of colour makes them look artificial, but I love them and they've rooted well from root-cuttings taken in summer.
I also like Eryngiums but have only managed with purchased plants. I have tried several time sto grow from seed - including putting the seed in the freezer, and all the other 'tricks' that I have read about. Where have I gone wrong?
HI, FOR THE FIRST TIME I HAVE PUT GLADIOLI IN MY GAREN BUT THE Y HAVE NOT FLOWERD, DO THEY NOT FLOWER INTHE FIRST YEAR , HAS IT BEN TO WET, THEY HAVE PLENTY OF SUN AND I HAVE BEEN WATERING AND FEEDING THEM AS RECAMENDED, WHAT IS HAPPENING I HOPED THAT I WOULD HAVE SOME FABULOUS GLADIES ... HELP PLEASE!;>(
I have 3 Eryngiums not sure of the variety but all are fab this year, as for stakeing them I found the best thing is the wire rings that are pushed over canes, they can be added one by one as the spikes of flowers come up and are better than trying to tie them to sticks that never seem to let the plants look natuaral. I have notice they dont set seeds easy as Ive only found one one seedling in 4 years and I do leave the heads on.
I have four Eryngiums in the garden three tall ones and one small they are great for bees and hover flys as mine are covered in them all the time i bought them new this year as i lost all of them last year hope they will be alright this year.
Ive always liked the look of Eryngiums but ive never grown them in my garden. Ive only got a small garden and they look as if they grow quite big, my front flower bed is quite narrow so i think they my look a little over powering. The colours of them are just beautiful though especially the blue.
while i have never suceeded in germinating eryngium indoors they do self sow in the garden particularly a virulently green and fleshy descendant of oliverium, if someone can tell how to germinate giganteum-which for me is a resolute non performer-i would be in your debt if not forever at least until i want to know something else
