it provides a source of calcium for plants; it improves water penetration for acidic soils; it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils. [2] Other forms of lime have common applications in agriculture and gardening, including dolomitic lime and hydrated lime.
Chalk heath is a rare habitat, in the temperate grasslands, savannas, and shrublands biome, formed of a paradoxical mixture of shallow-rooted calcifuge ("calcium-hating") and deeper-rooted calcicole ("calcium-loving") plants, growing on a thin layer of acidic soil over an alkaline substrate.

Dudleya pulverulenta exhibits a pollination syndrome uniquely adapted to hummingbirds.The flowers have long red petal tubes (corollas) and are unscented. The flowers hang downward (), achieved by a twist at the base of the terminal inflorescence branches, known as the cincinni, which inverts the flowers from the typically erect or ascending position seen in other Dudleya.
