Hawaiian Plant Textures

The images below link to PNG files for the texture maps which contain alpha channels (transparency). The width and height below indicate the real-life aspect ratio and size (in meters) for constructing the billboard; the textures themselves have been resized to convenient powers of 2.
I am placing these texture maps into the public domain; if you want higher resolutions or have any other questions or feedback, please contact me.

Plant: Coffee
Width: 1.6 m
Height: 1.8 m
Notes: A mature plantation specimen. Younger coffee plants have a single main trunk. This one has been pruned back multiple times. Photo taken in Holualoa.

Plant: Coffee (leaf)
Notes: 128x256 PNG with alpha

Plant: Fountain grass
Width: 1.0 m
Height: 0.8 m
Notes: Taken in a dry area. When more moisture is present, the plant is greener and may have many more flowering tassels.

Plant: Hapu‘u (tree fern)
Width: 3.2 m
Height: 3.2 m
Notes: A manicured plant from a landscaped yard, note the absence of any dead branches.

Plant: Hapu‘u (tree fern)
Width: 3.0 m
Height: 3.0 m
Notes: A wild specimen from a badly-taken photograph, color accuracy is poor and trunk is obscured.

Plant: Kiawe (mesquite)
Width: 5.0 m
Height: 4.0 m
Notes: A very difficult plant to create a texture for! The leaves are tiny, making the digitization blurry and edge following impossible. The result is a fairly bad texture.

Plant: Kiawe (mesquite)
Width: 3.0 m
Height: 3.5 m
Notes: Same problems as other kiawe texture. It's made more difficult by the fact that this desert plant's thin branches "silhouette" against the bright sky.

Plant: Koa
Width: 4.0 m
Height: 5.0 m
Notes: Taken from a young tree in my driveway, a good quality texture, well lit and decent color balance.

Plant: Koa Haole
Width: 2.0 m
Height: 2.0 m
Notes: A desert tree similar to kiawe, but smaller. Shares the same problems as kiawe (small leaves, hard to photograph and extract.)

Plant: Mamane
Width: 3.0 m
Height: 3.0 m
Notes: The beautiful yellow blossoms aren't very visible here, but it's a lovely endangered tree.

Plant: Ohi‘a
Width: 1.5 m
Height: 2.0 m
Notes: Young ohi‘a found growing on fairly new lava flow on the dry side of the island.

Plant: Ohi‘a
Width: 2.0 m
Height: 3.0 m
Notes: Young Ohi‘a found growing on fairly new lava flow on the dry side of the island.

Plant: Ohi‘a
Width: 4.5 m
Height: 9.0 m
Notes: Mature ohi‘a tree growing near Kilauea lookout on dry, dusty soil, mostly cinder. Many of the smaller branches got lost in the extraction process, but it's still a fairly good texture.

Plant: Ohi‘a
Width: 5.0 m
Height: 7.5 m
Notes: Another ohi‘a from the dry side of the Kilauea area. I didn't manage to fully remove the sky background color despite hours of pixel-by-pixel editing, but it looks OK on a billboard.

Plant: Olapa
Width: 1.0 m
Height: 2.0 m
Notes: Reportedly a "common shrub", but i haven't actually identified one in the wild; this was extracted from a found photo.

Plant: Papaya
Width: 2.0 m
Height: 4.0 m
Notes: I extracted this one before i developed any technique, so it's pretty rough and ugly. Hopefully it'll get replaced at some point.

Plant: Papaya (leaf)
Width: around 30 cm
Height: around 30 cm
Notes: This is the largest leaf from an adult tree; the smaller leaves are highly similar, just scaled down.

Plant: Papaya (bark)
Notes: 128x256 PNG, made to be wrapped once around the trunk, tileable in both directions

Plant: Strawberry Guava
Width: 0.75 m
Height: 3.0 m
Notes: Grows in clumps, almost never in isolation. I had to cut this specimen down and photograph it in sections. The plant is thin and tall because it was competing with all the other plants around it for sunlight.
