How To Grow
Good pest and disease resistance
Generally unaffected by pests, but may rarely be affected by leaf and bud eelworms. These stunt the plant's growth and make yellow/brown/black blotches on the leaves. To treat, remove dead leaves and soak the plant in hot water while it is dormant - this will kill the worms. To prevent downy mildew, space the plants adequately to prevent overcrowding and tight, humid conditions. Water at the base into the soil, not on the leaves, and try to prevent the water splashing off the soil and onto the leaves.
Water regularly in summer
This plant needs nothing more than rain water throughout most of the year. During hot, prolonged dry periods in summer however, you may have to give the plant a good watering several times a week. If the plant starts to look distressed and the soil around it is very dry, then give the plant some more water and check up on it the next day.
Full sun
Eryngium needs a sunny spot with around 6-8 hours of sunlight per day
Any fertile, well-drained soil
Plant in any fertile, well-drained soil. If your soil is particularly poor or clay heavy, add some garden compost with perlite to improve drainage.
Feeding not required
This is a low maintenance plant which gets all the nutrients it needs from the soil. ?v=1613300718

Best plants you will ever get online
I have ordered plants from them twice this year. They arrived well packaged, on time and looked strong and healthy. I feel the staff from Roots plants deal with their plants and customers with passion and care. I can’t wait to order again, price is good as well.

Delivered quickly, perfectly packaged and the tree was in excellent condition. Really healthy and taken to the garden with no problems. Can't recommend highly enough. 5 stars isn't enough!
John Harris
Satisfied customer
Unlike other online sellers, this company are well ahead in the quality stakes. My plant arrived promptly as per their promise and the plant was much more established and healthy than I had expected. It’s the second time I have ordered from them and I have faith in their promise. Excellent service.

A really good quality tree, delivered on time and very well packaged. But the emailed planting advice and supporting information was what really impressed me. Thoroughly recommended.
