Rosa hemisphaerica

Rosa hemisphaerica, also known as the sulphur rose,[3] is a rose species with pale yellow flowers native to western Asia.[4] The wild form, known as Rosa raphinii, has single flowers with five petals. A double-flowered form was one of the first yellow roses introduced to European gardens; John Bellenden Ker Gawler stated in 1815 that the species had been cultivated in England for nearly 200 years.[5] The scent of the flowers has been described as unpleasant.[6]

gollark: <@288568024498438145> It's less horribly resource intensive and has a built in mods API.
gollark: Bedrock Edition is waaay better for that, but also wrecks moddability and has many other antifeatures.
gollark: It seems to be the case that Java Edition is just horribly technically unsound.
gollark: I mostly agree. Not sure whether it's just being used to Minecraft, not having any of the various available UI enhancement or whatever mods, or just it being badly designed, but it does seem worse somehow.
gollark: Anyone interested in Mine*test*, an open-source Minecraftish game? I could probably host a server for that. I have to admit it's definitely not as polished, but there seem to be some good mods around for it.https://www.minetest.net/
