Chylismia claviformis is a species of wildflower known as browneyes or brown-eyed primrose. It is an annual plant growing from a basal rosette of long oval leaves and producing stems often exceeding half a meter in height. Atop the stem is an inflorescence of one to many primrose blooms, each with four white or yellow petals. The pistil may be quite long and has a bulbous stigma at the tip. The stamens are somewhat shorter and they bear long hairy anthers containing white or yellow pollen. The floral axis at the junction of male and female parts is bright red to maroon or brown. This species is found across western North America from the Pacific Northwest to northern Mexico. There are many subspecies: C. c. ssp. aurantiaca – found in desert regions C. c. ssp. claviformis – native to the Mojave Desert and nearby C. c. ssp. cruciformis – native to the Great Basin region C. c. ssp. funerea – native to the Mojave Desert C. c. ssp. integrior C. c. ssp. lancifolia – (lanceleaf browneyes) – California east of the Sierra Nevada C. c. ssp. peeblesii – (Peebles' browneyes) – found in Arizona and New Mexico C. c. ssp. peirsonii – (Peirson's browneyes) – native to Southern California and northern Baja California C. c. ssp. rubescens – native to Arizona C. c. ssp. wigginsii C. c. ssp. yumae – (Yuma browneyes) – found in the Sonoran Desert
Brown-eyed evening primrose has good resistance to disease and is generally not prone to illness. Still, it can be affected by pests and diseases present in its environment. These outbreaks are typically not severe. For care, this plant requires a moderate level of attention. It should be pruned regularly to keep a neat appearance and encourage healthy growth. Fertilizing can also aid in boosting flower production. Brown-eyed evening primrose is suitable for anyone with outdoor space, like a garden or patio, and does not demand extensive gardening experience. It may need extra attention when grown indoors.
How to keep Chylismia Claviformis.
Light
Brown-eyed evening primrose comes from bright, open habitats and performs best in full sun. It can tolerate partial shade but favors direct sunlight for optimal growth. This plant, which may be annual or biennial, is known for its sun-loving habit.
Temperature
Brown-eyed evening primrose can tolerate a broad range of temperatures, but its distribution may still be constrained by various combinations of moisture and heat. It performs best in warm summers with sufficient rainfall or irrigation. Extended spells of cloudy, rainy weather or prolonged high temperatures increase the chance that the plant will die. In winter, suitable protection from cold can boost the plant's survival rate.
Fertilizer
When most of the Brown-eyed evening primrose's blooms have opened to full size, resume fertilizing. During the period of peak bloom, apply fertilizer every three to four weeks, as the weather allows. Then, once the plant begins producing fewer new blooms, stop fertilizing; there's no need to fertilize when it can no longer produce more flowers.
