This Kiełki icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The bottom of the icon is a single line creating the illusion of a rocky or dirt packed ground, with a plant growing up through the loose sediment. The plant has three simple leaves growing ladder-like, one on each side not rooted in.
