Campanula rotundifolia, the common harebell, Scottish bluebell, or bluebell of Scotland, is a species of flowering plant in the bellflower family Campanulaceae. [2] This herbaceous perennial is found throughout the temperate regions of the northern hemisphere. In Scotland, it is often known simply as bluebell. It is the floral emblem of Sweden where it is known as small bluebell. [3] It produces its violet-blue, bell-shaped flowers in late summer and autumn.
The Latin specific epithet rotundifolia means "round leaved". [4] However, not all leaves are round in shape. Middle stem-leaves are linear. [5] : 707
Campanula rotundifolia is a slender, prostrate to erect herbaceous perennial, spreading by seed and rhizomes. The basal leaves are long-stalked, rounded to heart-shaped, usually slightly toothed, with prominent hydathodes, and often wither early. Leaves on the flowering stems are long and narrow and the upper ones are unstemmed. [6] The inflorescence is a panicle or raceme, with 1 to many flowers borne on very slender pedicels. The flowers usually have five (occasionally 4, 6 or 7) pale to mid violet-blue petals fused together into a bell shape, about 12–30 mm (15⁄32–1+3⁄16 in) long and five long, pointed green sepals behind them. Plants with pale pink or white flowers may also occur. [6] The petal lobes are triangular and curve outwards. The seeds are produced in a capsule about 3–4 mm (1⁄8–5⁄32 in) diameter and are released by pores at the base of the capsule. Seedlings are minute, but established plants can compete with tall grass. As with many other Campanula species, all parts of the plant exude white latex when injured or broken.
The flowering period is long and varies by location. In the British Isles, harebell flowers from July to November. [6] [7] : 250 [8] In Missouri, it flowers from May to August; [9] in Minnesota, from June to October. [10] The flowers are pollinated by bees, but can self-pollinate.
Campanula rotundifolia was first formally described in 1753 by Carl Linnaeus. As of 2023 [update] , no varieties or subspecies of Campanula rotundifolia are accepted in Plants of the World Online (POWO). [11] Several species have been previously described as varieties or subspecies of C. rotundifolia:
Although POWO and World Flora Online (WFO) [22] accept these as separate species, most English language sources do not. For example both the Database of Vascular Plants of Canada (VASCAN) and the USDA Natural Resources Conservation Service PLANTS database (PLANTS) do not accept any of these species as valid or even regard them as valid subspecies. [2] [23] This is also the case with authoritative floras such as Flora of Colorado. [24]
While it is now commonly known as harebell or bluebell, it was historically known by several other names including blawort, hair-bell, lady's thimble, witch's bells, and witch's thimbles. [25] [26]
Elsewhere in Britain, "bluebell" refers to Hyacinthoides non-scripta , and in North America, "bluebell" typically refers to species in the genus Mertensia , such as Mertensia virginica (Virginia bluebells).
Campanula rotundifolia occurs from Spitzbergen, [6] extending in mainland Europe from northernmost Scandinavia to the Pyrenees and the French Mediterranean coast. [27] It also occurs on the southern coasts of Greenland, on Iceland and on southern Novaya Zemlya. [27]
Some sources and authorities like the VASCAN and PLANTS do not currently separate out different species for North America. [2] [28] [23] If using these sources it is widely distributed through North America including all of Canada and most of the United States.
It occurs as tetraploid or hexaploid populations in Britain and Ireland, but diploids occur widely in continental Europe. [29] In Britain, the tetraploid population has an easterly distribution and the hexaploid population a westerly distribution, and very little mixing occurs at the range boundaries. [6]
Harebells grow in dry, nutrient-poor grasslands and heaths. The plant often successfully colonises cracks in walls or cliff faces and stable dunes. [6]
C. rotundifolia is more inclined to occupy climates that have an average temperature below 0 °C in the cold months and above 10 °C in the summer. [30]
In Iceland, research on Campanula rotundifolia has revealed that it is a host of at least three species of pathogenic fungi, Coleosporium tussilaginis , Puccinia campanulae and Sporonema campanulae (and the teleomorph Leptotrochila radians ). [31]
The harebell is dedicated to Saint Dominic.[ citation needed ]
In 2002 Plantlife named it the county flower of Yorkshire in the United Kingdom. [32]
William Shakespeare makes a reference to 'the azured hare-bell' in Cymbeline:
Christina Rossetti (1830–1894) wrote a poem entitled 'Hope is Like A Harebell':
Emily Dickinson uses the harebell as an analogy for desire that grows cold once that which is cherished is attained:
Trillium erectum, the red trillium, also known as wake robin, purple trillium, bethroot, or stinking benjamin, is a species of flowering plant in the family Melanthiaceae. The plant takes its common name "wake robin" by analogy with the European robin, which has a red breast heralding spring. Likewise Trillium erectum is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick.
Hyacinthoides non-scripta is a bulbous perennial plant found in Atlantic areas from the north-western part of the Iberian Peninsula to the British Isles, and also frequently used as a garden plant. It is known in English as the common bluebell or simply bluebell, a name which is used in Scotland to refer to the harebell, Campanula rotundifolia. In spring, H. non-scripta produces a nodding, one-sided inflorescence of 5–12 tubular, sweet-scented violet–blue flowers, with strongly recurved tepals, and 3–6 long, linear, basal leaves.
Campanula is the type genus of the Campanulaceae family of flowering plants. Campanula are commonly known as bellflowers and take both their common and scientific names from the bell-shaped flowers—campanula is Latin for "little bell".
Campanula carpatica, the tussock bellflower or Carpathian harebell, is a species of flowering plant in the family Campanulaceae.
Heracleum sphondylium, commonly known as hogweed or common hogweed, is a herbaceous perennial plant in the carrot family Apiaceae, which includes fennel, cow parsley, ground elder and giant hogweed. It is native to most of Europe, western Asia and northern Africa, but is introduced in North America and elsewhere. Other common names include cow parsnip or eltrot. The flowers provide a great deal of nectar for pollinators.
