Indian paintbrushes are parasitic plants.
Indian paintbrushes can still photosynthesize just like any other plant, but they are better able to survive poor weather conditions by stealing from their neighbors.
Paintbrushes parasitize other plants using structures called haustoria. Haustoria attach to the roots of host plants, creating a connection that allows the paintbrush to steal nutrients and water.
Indian paintbrushes vary in color.
Paintbrushes can be found in shades of red, pink, and yellow. In California, they bloom from February to May, allowing you to witness their different colors.
The top “brush” of the plant isn’t a flower.
The top “brush” of the indian paintbrush deceptively looks like a flower. This showy top is actually composed of modified leaves, which house the flowers. The flowers themselves look like small tubes.

Indian paintbrushes don’t make very good garden plants.
Because they are parasitic and require a host plant, it is very difficult to grow indian paintbrushes in your garden. While I’ve never tried it myself, gardeners have found success in growing paintbrushes in the same pot as a good host plant.
