Input (English): Context_1 : Blandfordia punicea, commonly known as Tasmanian Christmas bell, is a species of flowering plant which is native to western Tasmania in Australia. Context_2 : Blandfordia is a genus of flowering plants, placed in the family Blandfordiaceae of the order Asparagales of the monocots. The genus is native to eastern Australia. Plants in this genus are commonly referred to as Christmas bells due to the shape of their flowers and the timing of their flowering season in Australia. "Blandfordia" was named by English botanist James Edward Smith in 1804 in honour of George Spencer-Churchill, 5th Duke of Marlborough, the Marquis of Blandford. Context_3 : Comfrey (also comphrey) is a common name for plants in the genus "Symphytum". Comfrey species are important herbs in organic gardening. It is used as a fertilizer and as an herbal medicine. The most commonly used species is Russian comfrey "Symphytum" × "uplandicum", which is a cross or hybrid of "Symphytum officinale" (common comfrey) and "Symphytum asperum" (rough comfrey). Context_4 : Blandfordia grandiflora is a species of flowering plant native to south-eastern Australia. "B. grandiflora" is commonly known as the large Christmas bell because it generally flowers in December and January. It is a perennial herb, and has tubular, bell-shaped flowers. It is one of only four "Blandfordia" species. Context_5 : Symphytum asperum is a flowering plant of the genus "Symphytum" in the family Boraginaceae. Common names include rough comfrey and prickly comfrey. It is native to Asia and it is known in Europe and North America as an introduced species and sometimes a weed. Context_6 : Symphytum officinale is a perennial flowering plant of the genus "Symphytum" in the family Boraginaceae. Along with thirty four other species of "Symphytum", it is known as comfrey. To differentiate it from other members of the genus "Symphytum", this species is known as common comfrey or true comfrey. Other English names include Quaker comfrey, cultivated comfrey, boneset, knitbone, consound, and slippery-root. It is native to Europe and it is known elsewhere, including North America, as an introduced species and sometimes a weed. The flowers are mostly visited by bumblebees. Context_7 : An herb farm is usually a farm where herbs are grown for market sale. There is a case for the use of a small farm being dedicated to herb farming as the smaller farm is more efficient in terms of manpower usage and value of the crops on a per acre basis. In addition, the market for herbs is not as large as the more commercial crops, providing the justification for the small-scale herb farm. Herbs may be for culinary, medicinal or aromatic use, and sold fresh-cut or dried. Herbs may also be grown for their essential oils or as raw material for making herbal products. Many businesses calling themselves an herb farm sell potted herb plants for home gardens. Some herb farms also have gift shops, classes, and sometimes offer food for sale. In the United States, some herb farms belong to trade associations. Context_8 : Symphytum caucasicum, the beinwell, blue comfrey, or Caucasian comfrey, is an ornamental plant of "Symphytum" genus in the Boraginaceae family, which is native to Caucasus. Context_9 : The Johnson Papyrus (London, Wellcome Library, MS 5753) is a fragment of an early 5th century AD herbal. It is the oldest extant manuscript illustration of a plant. The papyrus fragment shows a sphere of dark blue-green leaves supported by some small scraggly roots. Below the illustration is a fragment of Greek text. The illustrated plant has been identified as "symphyton" (modern comfrey), which was an important medicinal plant. However the illustration does not closely resemble comfrey, so that, if the identification is correct, the illustration would have had been of little use as an aid to identification. Context_10 : Symphytum tuberosum, the tuberous comfrey, is a species of "Symphytum" in the Boraginaceae family. fact_1 : Blandfordia is a genus of flowering plants, placed in the family Blandfordiaceae of the order Asparagales of the monocots. fact_2 :  Comfrey species are important herbs in organic gardening. Question: Are Blandfordia and Comfrey both herbs?
