Usually, the yerba mansa, scientific name Anemopsis californica, is depicted as a perennially growing herb. Native to the United States, this herb grows most actively during the spring and summer.

The foliage of this plant is green and it produces unremarkable white blooms along with plenty of prominent brownish fruits or seeds. The yerba mansa produces maximum blooms at the onset of spring, while the fruits and seeds are produced from the beginning of spring to the end of the season.

The yerba mansa is found growing in stands in marshes and boggy swamps, along river banks. For instance, this herb is found growing naturally along the Colorado River and downstream into some places in Mexico like Chihuahua and Sonora.

This plant does not grow very tall and bears smoothed and slightly juicy leaves whose length may vary from 3 inches to 6 inches. The leaves grow right from the base of the plant. The blooms of yerba mansa bear resemblance to coneflowers.

However, unlike coneflowers, the blooms of yerba mansa have white spikes and bracts at their base. Like eucalyptus, this plant is very aromatic. The green foliage of the plant changes to brick red during fall.

The leaves of yerba mansa have a shade of blue and they bear resemblance to those of spinach. However, unlike the spinach, yerba mansa leaves are heavier as well as thicker, while they feel cool and smooth when touched. During the fall, the leaves of this herb develop reddish and black spots and usually they die completely or wither away in winter.

Yerba mansa blooms have snow-white hue with yellow stamens and pistils that are concealed in white bracts (petal-like modified leaves). These flowers appear in conical one-inch clusters.

The flowers of this low-growing plant usually bloom in spring or the middle of summer. The blooms easily become desiccated producing reddish-brown spiky seedpods that remain on the plants for many months.

Yerba mansa plants readily propagate through an asexual method, as their runners give rise to new plants, each having one or several nodes that produce new leaves as well as roots. The white roots of this plant are long and threadlike. When young the roots are brittle and become corky and develop bark that covers them when they mature.

The clean spicy aroma of yerba mansa is the most characteristic attribute of this herb. This fragrance is always in the air when near the plants and is emitted more potently when their leaves are squashed.

The aroma released by yerba mansa leaves is somewhat similar to a blend of eucalyptus and wild ginger. In fact, many aromatic elements present in eucalyptus and wild ginger are also found in the yerba mansa leaves.

After the seedlings have grown reasonably big and good enough to be handled, prick them out carefully and plant them in individual pots. Continue to grow the young plants in the greenhouse during their first winter.
