Here are some plants from the old website I think would make sense. Probably some of them are already what you find. I don't know. I cordially second everything suggested by valeria and nauta.Ashkiss
: Dusty grey and pallid, this sparse growth of lichen manages to survive on the minimal amounts of moisture in the air. Its powdery flakes look edible but utterly unappealing.
Grows in arid terrain, on rocks.Haspeth
: Much like a spineless cactus, this yellow plant has very thick skin. Thick yellow seeds can be picked off it.
Found in the Red Desert, this plant's seeds are edible.Jesstik
: They lie close to the ground, leaving barren earth between where the rounded edges join together here and there in a haphazard pattern to form a single mass which covers a broad swathe of ground. From centers of the largest rounded bumpy lumps protrude cord long crystalline spikes. On the very tip of some of these can be seen brittle, fragile looking blooms.
Grows exclusively in salty areas, and its decorative flowers and leaves bear a close resemblance to salt crystals.Jherweed
: The clump of weedy, light-brown tendrils that form this plant is spotted all over with tiny black seeds, about the size of a human's least fingernail.
Native to sandy wastelands.Joybane
: The round, woody stem of this plant is covered with small, rounded and lobed blue-green leaves dotted with oil glands which give off a strongly pungent aroma. Frilled, slipper-shaped greenish-yellow flowers blossom atop the rigid stem.
Named for the pungent oil the leaves release when handled, which causes the eyes to well up with tears, causing involunatary weeping. Used as a seasoning, this plant grows in both scrub and desert climes.Khee
: This spindly plant is over three cords in height and crowned with miniscule clusters of flat yellow flowers. The finely cut, lime green leaves are wispy-looking and deeply aromatic, with a sweet, anise-like fragrance. The bright green stalk seems to grow out of a fleshy, white bulb.
All parts of this plant are edible, and used in cooking or seasoning. The leaves are also used to make perfume. Found in a variety of terrains.Pech Grass
: Bladed in stiff, spearlike leaves, this tall grass grows a few cords high, shaded in dry browns and thin edged gold.
Good grazing, pech grass is the most common type of grass in the Known World.Marilla
: This brownish-white tree stands about five cords in height and is about as wide as a human's thigh. Its bark is smooth and hugs the tannish wood beneath as it rises from the ground, odd because of its lack of leaves.Maar
: This appears to be a maar tree, by its twisted, dark yellow appearance and stubby size. At no more than knee height its trunk divides into a tangled mess of branches, each fringed with fern-like maroon leaves.
One of the only trees not found in forests; it ekes out existence in desert-like conditions.Runebane
: Large oval leaves, crumpled and wilted a little from rough handling, are scattered with a mottling of white spots. A funnel shaped flower, purplish blue in color, is mixed in with the foliage.
Used in bandages and salves for its numbing properties, this plant is common in rocky, semi-arid regions.Sandspider
: Long and thin, this leaf looks a lot like a spider's leg. Reddish brown in color, it blends into the desert sands quite well.
Reputedly an elven aphrodisiac, this plant is found in the desert, as the name implies.Sivifi
: This wiry bush is clearly a product of the desert, its narrow, almost rectangular leaves designed to conserve their precious moisture. In color, they are grey, with only the slightest hint of green evident beneath the surface, shading to a dusty rose at the very tip. A few orange flowers grow deep within the bush, near the base, as shaded as possible by the upper foliage.
Its seeds are used to flavor one variety of cheese, and are edible themselves. Found in otherwise desolate areas, particularly in the southlands.Stingtongue
: This tiny leaf is perhaps an inch wide, perhaps a trifle less. It is perfectly circular, and a deep blue-green in color.
Named for its bitterness, this herb is useful in reducing fevers. Found in mesas and other stony areas.Tembotooth
: These leaves are long, narrow, and glossy green. Brushed, they release a warm, peppery scent with hints of anise.
Chewed for their mildly stimulating qualities, and used in cooking and seasoning, as well as in a spicy perfume.Templar's Heart
: Blossoms of a bright red, a shade resembling human blood, adorn each of the spidery crimson vine's lanky tendrils, spaced at intervals with slender, pronged thorns.
The flowers of this southern vine are used to make a rare perfume.Tenichi
: These long calyxed, purple flowers with bright yellow stamens are borne on long stalks, the leaves a glossy purplish green in color.
Growing in oases, this plant bears both vibrant blossoms and small edible figs.Thilareyn
: A sprawling tangle of vines running every which way, this plant seems to subsist on the dry climate of the desert. Tendrils depend from the vines, each one leading down into the ground, anchoring the plant. From the vines grow small, hard berries.
The berries of this desert vine are edible.Thugi
: This pepper plant thrives in rocky terrain. Its scraggly, purple-green leaves shade small, wrinkled black peppers.
This extremely hot, edible pepper grows in the southlands.
