Centaurea montana; The perennial cornflower actually is not an Icelandic species. I saw individual plants growing along a creek near Mosfellsbær, near Reykjavik in the mild climate region of Iceland. It probably somehow germinated from seed from a garden plant and settled in a semi-wild habitat. It is closely related to the common annual European cornflower.
It is a member of the Asteraceae family (= Compositae ), the daisy family. The Icelandic name of this species is Fjallakornblóm. See more: http://www.iceland-nh.net/plants/data...

Fjallakornblóm ( Centaurea montana ) er næst-algengasta kornblómið hjá okkur. Það er fjölært, grjótharðgert og getur orðið eldgamalt. Fjallakornblóm eru til blá, bleik eða hvít og eru bleiku fjallakornblómin sennilega skemmtilegasta garðplantan. Blóm bleiku fjallakornblómanna virðast fylltari en blóm hinna og því meira áberandi. Plönturnar verða 50­70 cm háar og er til bóta að binda þær upp, annars vilja stönglarnir leggjast út af í roki. Helsti ókostur fjallakornblóma er sá að þau eru ansi skriðul og nauðsynlegt að hafa auga með þeim eigi þau ekki að leggja allan garðinn undir sig. Á móti kemur að það er ekki erfitt að uppræta þau af stöðum þar sem þau eru óvelkomin. Blómgunartími fjallakornblóma er yfirleitt snemma í júlí og standa þau yfirleitt í 3­5 vikur.

‘Lavender Mist’ carries on fragrantly flowering and reflowering from early spring into late summer—a longer, more lingering bloom time in the garden. habit. See more: https://www.burpee.com/perennials/per...

Since the plant is evergreen it can use the light in winter and early spring when deciduous trees and shrubs have no leaves. It tolerates deciduous shade better than evergreen shade and prepares to flower while deciduous plant are bare. Therefore, it can flower reasonably well in light deciduous shade. If the plant is dug up, a new plant can eventually regenerate from small pieces of root left in the soil. Centaurea montana grows well in soils varying from light sand to heavy clay. The plant also grows well in acid, neutral or very alkaline soils. It tolerates drought but cannot tolerate waterlogged conditions. See more: https://en.wikipedia.org/wiki/Centaur...

Centaurea are copious nectar producers, especially on high-lime soils. The high nectar yield of the genus makes it very attractive to insects such as butterflies – including the endangered Karner blue (Lycaeides melissa samuelis) which visits introduced spotted knapweed – and day-flying moths – typically Zygaenidae, such as Zygaena loti or the six-spot burnet (Z. filipendulae). The larvae of some other Lepidoptera species use Centaurea species as food plants; see List of Lepidoptera that feed on Centaurea. Several of these are used in biological control of invasive knapweeds and starthistles. Larvae of several true weevils (Curculionidae) of the subfamily Lixinae also feed on Centaurea. Some genera – such as Larinus whose larval food is flowerheads – have many species especially adapted to particular knapweeds or starthistle and are used in biological control too. These include the yellow starthistle flower weevil (L. curtus) for yellow starthistle, lesser knapweed flower weevil (L. minutus) for diffuse knapweed and blunt knapweed flower weevil (L. obtusus) for spotted knapweed. Broad-nosed seedhead weevil (Bangasternus fausti) larvae eat diffuse, spotted and squarrose knapweed (C. virgata ssp. squarrosa), while those of the yellow starthistle bud weevil (B. orientalis) do not seem to live on anything other than yellow starthistle and occasionally purple starthistle (C. calcitrapa). But perhaps most efficient in destroying developing yellow starthistle seedheads is the larva of the yellow starthistle hairy weevil (Eustenopus villosus). Knapweed root weevil (Cyphocleonus achates) larvae bore into the roots of spotted and to a lesser extentely diffuse knapweed, sometimes killing off the entire plant.
