Oan Flora

Many plants common in this realm are known to Oa as well.  Plants The Ladies' Hiking Club have encountered that would not be familiar are as follows:
Amberwood: A deciduous tree with ribbed oval leaves, unremarkable in appearance but favoured by chefs for the flavour profile of its sweet and savoury smoke. Hickory and sugar root.
Arteritis Molunaria: An enticing mushroom similar in appearance to an oyster with an especially wide cap. Poisonous.
Black Ash: A species of ash tree known for its tar-black bark and wood. Otherwise indistinguishable from other species of ash.
Blechnum Fern: An almost "hairy" fern given the thinness of the fringes of its leaves. Small enough to serve as an only somewhat attractive houseplant. When its sap is mixed with dried reishi mushroom, the result is a herbal remedy for the Barrow Pox and certain other viral infections. Bitter and dry.
Fox Elm: Towering elm trees distinguishable from the generic only in their height (up to 90 feet tall) and the vivid orange hue of the wood inside its bark.
Healroot: A large succulent with deep green leaves and bluish veins, whose abundant clear sap is an effective and antiseptic coagulant. The sap can be dried and rehydrated through a process that preserves it for travel and actually improves its efficacy. Healroot powder is a common apothecarial ingredient. Notes of mint and endive.
Heartwood: A great, thick tree commonly 40 feet or more in diameter at maturity. Tends to grow branches early in development and to expand upon them over time rather than growing new branches closer to the root, with the result being 10 feet or more between the ground and the lowest branch on a mature tree. Named for the rapidly moving, flammable sap within that can be detected by touch. Contrary to the old wives' tales, the wood is not actually discernibly warmer to the touch than other woods at the same ambient temperature. Similar to mahogany in colour.
Hearthwood (or Weepwood): A cousin of the heartwood, growing thinner but still exhibiting similar characteristics. So named for the tendency of the sap to drip out in ugly black beads, coating the bark and making for ideal emergency firewood. Burns when wet.
Lime-Pitcher (or Seagrape): A plant in the shape of an overgrown calla lily, but comprised almost entirely of a fibrous, thick, celery-like material. Its "bucket" holds rainwater and entices birds to bathe and eat the small green berries sprouting in runners from the top (inedible to humans). A very effective waterproof roofing or rafting material in the hands of an Elven craftsman. The berries are sour to the point of being inedible but can be diluted with sugar into a popular taffy.
Parlroot: A woody-stemmed tubor with an appearance similar to mature, thick thyme shoots. Its pale brown roots, similar to radishes in size and shape, can be dried and crushed into an effective antifungal agent. Notes of sweet potato and pecan.
Reishi Mushroom: Similar to the fungus of the same name in our world. When dried, crushed and mixed with the sap of a blechnum fern, the result is a herbal remedy for the Barrow Pox and certain other viral infections. Woody, smoky and very chewy.
Sparkweed/Sparkroot: An orange thistle plant whose roots contain an oil that, when extracted, can be crafted into an incendiary. Repulsive battery-acid flavour.
