Buy Eryngium bourgatii 'Picos Amethyst' sea holly: New variety with deep blue flowers

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun
  • Soil: dry, well-drained, poor to moderately fertile soil
  • Rate of growth: average
  • Flowering period: July and August
  • Hardiness: fully hardy

    Easily recognised by their ruff of spiky bracts surrounding a prominent, cone-like centre of tiny flowers, sea hollies make a bold statement in a sunny border or gravel garden. This variety has deeply cut, deep blue bracts held on stiff, blue stems in July and August. The attractive, dark green, marbled foliage, which appears before the flowers, is shown off to best effect planted in gravel. Or try it in bold clumps among grasses. Eryngiums are also perfect for use in dried flower arrangements.

  • Garden care: Lift and divide large colonies in spring. Avoid the temptation to cut back the flower-heads in autumn as they provide interest in the winter garden.

Long lasting, very pretty


Lovely plant, but requires some staking.

Beautiful colour and will be buying more


Well packaged and healthy plant, delivered in good time. Planted out as soon as it arrived and, despite recent very hot weather, plant has survived the heat well. Will be buying more of these Eryngiums for my borders.




I would like to see other versions of this plant


This is difficult because I am still waiting for this plant to flower so I cannot comment at the moment.

Hi. I love sea holly and would like to use live plants in decorative pots as centrepieces on the tables at my ceilidh party in mid-October. After the event they will be planted in our garden (dry sunny site). If I buy 9cm pots from you now and care for them through summer, are their foliage/flowers likely to look attractive in mid-October? Thank you

Ceilidh dancer

Hello, The foliage of these plants tends to die back in autumn, so they wont be looking their best in mid-October. The flowers however tend to dry well, so they could be used in that way.


I have just received my Eryngium bourgatii Picos in a pot. I note that this is hardy but as it is so small, when should I plant it out into the garden. Or should I keep it potted until next Spring? Thanks Helen


Hello, This plant will be around a year old in a 9cm pot, so provided you are planting into freely draining soil, you can pop it straight in the border. If however you have a particularly exposed garden, or are worried about it getting trampled on or damaged in some way, then you can pot it up and plant it out when it is a little older.


Hi I have just moved to a seafront property and am going to buy sea holl and grasses for the garden. Can you suggest anything else. The area is 1 meter wide by 4 meters long at the side of the drive way. Full sun in the morning until about 1 pm. Thank you.


Hello there I have attached a link below to plants that will tolerate a coastal garden. You can then refine the search to match your requirements.

How big does this plant grow and how tall? Would it be ok in a gravel garden on clay?


Hello, These plants have an eventual height of 55cm and spread of 50cm, but it prefers a freely draining poorer soil. I have however seen them growing happily on clay-based soils provided they are do not retain too much water.


Sea Holly going dark brown? Hi, I was so pleased with the beautiful 'Sea Holly' recently purchased from your web-site. I am not at all familiar with sea hollies, but I planted it in a very sunny position into my clay soil. It seemed very happy there for a few weeks, but is now looking unhealthy with some brown leaves. I think it may be due to the heavy rain of late. I would appreciate some advice regarding same. Kind Regards, Linda

Linda Payne

I agree eryngiums need well drained soil and sun. if you want to give them another go try improving your soil with manure and then adding grit to the planting hole.


Hello Linda, Eryngiums love well drained, poor soils with lots of sun, so if it is not flourishing, it is possible that your soil is too heavy and wet for it - especially after all this rain we have had. The best thing you can do then is to move it to a soil that has better drainage (or even a pot) and it should pick up.

Eryngium bourgatii' Picos Amethyst' Hello I bought 2 Eryngium bourgatii 'Picos Amethyst' from you in April. One of them has flowered beautifully (amazing colour) and the other one has just sat there sprouting more leaves. They are close to each other - could that be the problem, the flowering one taking all the nutrients from the other one - or is there something else wrong? Any advice, gratefully received. Many Thanks, Edel

Edel Erickson

Hello again Edel, Do give it a feed, but I would not expect to see instant results - it may be that the plant won't flower until next year. Best regards, Helen Plant Doctor

Crocus Helpdesk

Hi Helen That's great. Thanks a lot. I'll give it a feed and see what happens - such a brilliant plant. Thanks Edel

Edel Erickson

Hello Edel, There may not necessarily be anything wrong, but one may be putting most of its energies into producing leaves rather than flowers. Unfortunately plants do not always grow in the same way, but given the right conditions there is no reason why it won't eventually flower. All you need to do is make sure it gets well fed and watered and gets plenty of sun. If you want to give it a bit of a push you can feed it with Tomorite. I hope this helps. Helen Plant Doctor
