Notable Flora

Found here is a short list of plants found throughout the realms. While most are notable for their healing or toxic properties, a rare few are of botanical or religious importance.

Plants as Exotic Components

The plants on this list can be used for the creation of magic items, functioning as CR 1/2 components. Additionally, unlike monstrous components, plant components can be stacked together (e.g. four CR 1/2 Winter Willow is equivalent to a CR 2 component).

Tundra

Plants found in central and northern Meridon and northern Cambria.
Winter Willow. The bark of this short, bushy willow can be chewed to invoke a deep, lasting sleep. A strip of dried bark can be burned in a censer to replicate the Sleep spell; if you cast the spell while burning a strip of this bark, you can roll d12s in place of the spell's usual d8s. In either case, the bark is consumed.
Wintercrest. This short, coiled flower can be brewed into a tea with properties similar to healing potions.

Underdark

Ubiquitous throughout the deep subterranean.
Blood Moss. This macabre plant is a deep red hue and flourishes in dark places where incantations of death and dark rituals have been uttered. Owing to this grim providence, blood moss is common in the underdark where the Nachthyr often carry out rituals to their Lord of Nightmares, Malgelirion, however blood moss can sprout in any cave or dark place and is not limited to the underdark. Unsettlingly, this moss leaves bloodstains on the fingers. The moss is a potent tool for enhancing curses.
Violet Lichen. Found far from the reaches of sunlight, tincture made from this stone-hard lichen is valued for its regenerative properties.
Spice Caps. A delightfully common mushroom that provides pleasant flavour to the otherwise bland dishes found in the underdark. While deep gnomes and druergar are adamant that spice caps not be exposed to sunlight, few know why.
Dream caps. Small, spindly mushrooms found in the shallow underdark. These mushrooms can produce hallucinations, and the the Nachthyr use them in their rituals. A character with proficiency in Alchemy Tools can use three of these caps to produceEssence of Ether with 2 hours of work, provided they have tools on-hand. Additionally, when you use a Dream Cap as a component for the Sleep spell, the cap is consumed and you roll four additional dice for the spell.

Gloomlings. Shaggy, bone-white mushrooms that dissolve themselves in pools of inky darkness. These mushrooms were introduced from the Shadowfell, but now thrive in the deeper caverns of the underdark. Smeared on iron weaponry, Gloomlings replicate the effect of the Shadow Blade spell. When consumed as a material component for Shadow Blade, the conjured weapon gains the Reach property, and the thrown range is doubled.

Temperate

Plants found predominantly in Cambria, Nuriliath highlands and southern Meridon.
Angelica. A tall, stout stalk topped with an umbrella of white flowers. Burning the dry flowerheads in a censer for 1 minute is akin to a casting of the Remove Curse spell, and is occasionally a necessary component (alongside a supplementary casting of the spell itself) to rid oneself of more potent curses.
Apostolos (Nystulian) Rose. Deep green leaves and slender white thorns. A rare plant found only in elven territory and far inland, yet this flower blooms only when fed saltwater. Large flowers of shifting hues can be used as a true panacea, capable of curing virtually any illness or curse. A Nystulian Rose grows can be plucked only by one of good intent, and never more than one at a time.
Basilisk's Breath. A broad flower found in montane regions. A decoction brewed from the flower head delivers near-instant paralysis.
Black Garlic. Mundane as ingredients come, but a head of garlic properly blackened has minor restorative properties and grants a weak, but notable resistance to poisonous effects.
Bleeding Tooth Fungus. Decoctions of this fungal sap warm the body and provide protection against low temperatures. A character proficient with Alchemy Tools can use five Bleeding Tooth Fungus to create a Potion of Resistance (cold only) with 2 hours of work, provided they have access to the requisite materials.
Bloodwood Petals. The bone white petals of Bloodwood tree flowers can be used to make holy oils, waters and ointments. A functional replacement for powdered silver for divine magic. When used as a component for Bless, the spell's strength is heightened.
Burnt Bloodwood Tinder. The fallen boughs of a Bloodwood tree, once charred over a holy flame, can protect one from the influence of dark magic.
Devil's Bloodleaf. Distinct leaves of a deep-read colour found in hills, swamps and rarely in the shallow underdark. Long-term distillates of this plant can ease the effects of most poisons and diseases. Some such distillates have been known to induce phantasms, as well. A common ingredient for Potions of Poison Resistance (Uncommon), Potions of Disease Resistance (Uncommon).
Eyebright. A rare herb of white and purple-streaked flowers found in swamps and other wet climates. The crushed flower petals can be distilled with healing elixirs to improve vision and cure blindness.
Honeysuckle. Effects unknown.
Ironwood Bark. The bark of the ironwood tree is, unsurprisingly, extremely rigid. It's valued by alchemists for its use in Stoneskin potions and potions of Stone Giant Strength. Chewed raw (if one can manage it), it grants effects similar to the Barkskin spell and, if used as a component for Barkskin by a competent druid, the bark extends the spells duration eight-fold.
Kingsfoil. A plant largely ignored by modern healers who have long forgotten its uses. In days of old, a salve made from Kingsfoil leaves was said to ease the touch of dark magic. Ancient lore tells of greater potency when this salve is prepared by king's hand.
Lavender. Bushels of dried lavender flower-spikes can be stewed into an alchemical brew to dampen magical effects, or ground and powdered over a conjuring circle to strengthen the bond between spellcaster and minion. Beware, large quantities are harmful to spellcasters.
Quicksilver Lichen. A reduced, silvery lichen. Alone, this lichen provides no alchemical value, yet its addition is known to improve the potency of most other poisons.
Stranglevine Seeds. An unusual seed the size of a thumbnail and protected by tiny thorns. Adult stranglevine plants are very rarely found in elf-lands, yet these seeds inevitably find their way into the hands of elven warriors or their allies when elven territory is threatened. When used as a component for Entangle, the roots conjured by the spell crush and strangle their victims, dealing 1d6 damage per level of the spell when a creature starts its turn entangled.
Valerian. A tall, stiff grass-like stalk bearing a cluster of white and pink flowers. The smell of valerian is ever calming. Dried valerian flower burned in a censer can replicate the effects of a Calm emotions spell. If you burn these flowers while casting the spell yourself, the spell can affect beasts and monstrosities in addition to humanoids.
Vervain. Effects unknown.
Wisp's Stalks. Tall, pale and nearly invisible stalks found in deep forests or the shallow underdark. The faint magic that grants these stalks their semi-transparency can be used to brew potions of invisibility. When crushed, they replicate the Invisibility spell. When expended as a component of the Invisibility spell, targets of the spell gain +10 to Stealth checks made while the spell lasts.
Witch Hazel. Effects unknown.
White Cap. The caps of this mushroom rehydrated in a boiling decoction of king's water are common in any school of magic for their restorative properties on spell reserves, though such decoctions often cause an unnatural chilling as a side-effect.

Warm Arid

Plants found in Bharazad and parts of Nuriliath and Redcliffe.
Beryl's Breath. Long white trumpet flowers hanging from a low tree. Expert alchemists have used Beryl's breath to concoct truth serums.
Spineflower. Tall stalks bearing long, thine spines and small flowers. Found predominantly in deserts and the Plane of Fire. Similar to *Quicksilver Lichen*, the flowers of this plant are ineffective on their own, but potent amplifiers of other poisons.
Ephedra. A rare and useful find for the wandering alchemist, the succulent stalks of this leafless plant are a potent amplifier in other healing elixirs, but useless on their own.
Torchwood Gum. The dried gum of the torchwood tree has effective divine properties, and has been used to make holy oils, waters and ointments. A functional replacement for powdered silver for divine magic.

Sub-tropical

Plants found in Anderim, Melorn, Bedegar, Dumont, Redcliffe, Nuriliath lowlands and parts of Bharazad.
Fennel Silk. A tall, long-stalked plant resembling fennel. The plants fibers can be boiled and partly dissolved with alchemical solvents to stabilize body heat against particularly cold or wet weather for a short time.
Willowherb. A tall stalk crowded by small, pink flowers in high summer. Fields of willowherb grow rapidly after wildfires. The flower petals can be used to brew a tincture for pain relief; beware however, this tincture does not cure wounds, only allow the imbiber to ignore them longer.

Extraplanar

Plane of Fire

Cinderbell. A long vine with hanging, bell-shaped flowers filled with cinder-like pollen. A sacred herb of Juno, daughter of Artoš. Cinderbell pollen holds useful fire-resistant properties while the seeds bear potent regenerative properties to druids of Artoš.
Desert Rose.
Serpent Tree. A black, leafless plant that feeds on heat rather than sunlight. Wizards prize the dark wood of this tree for making Wands of Fireball, after appropriate magical treatment.
Tergamit. A bumpy, round orange fruit considered a delicacy by the Efreet native to the plane of fire and dangerously poisonous to others. To Fateborn, the fruit function as a Goodberry on their own (restoring 1 hit point), and if the fruit are used as a material component for casting Goodberry each fruit instead restores 1d8 hit points.
