Hibiscus flowers have been released at Arctic Greenhouse. These feature a fully sculpted stamen (center piece), and are one of the most detailed prim flowers I've released yet. Also one low-prim version is available weighing in at only 4 prims. They can be found at planter pictured below on the east side of the store.
You can also get all the low prim and high prim pieces and color textures together in a full perm kit, also available now.
