PALE EVENING PRIMROSE
Oenothera pallida

Easy, fast growing and long blooming plant that flowers from spring to end of summer. Its flowers are white and centered with a lime green eye
and stay open all day; the blossoms have a sweet almond fragrance.
It is highly variable in its growth characteristics: It can be an annual or, more commonly, a perennial. Plants often spread from roots and can be so abundant that an area is dotted with red stems in early spring and then with numerous white flowers. Petals have noticeable yellow/green patches at their base. After pollination the flowers turn pale pink or lavender.

Lateral roots may give rise to new perennial plants.
Showy four o'clocks are perennial plants that
die back to their roots each year.
It has funnel shaped flowers that bloom from April to September, especially after rains. The fruit is a small dark seed that is often held in the papery floral cup,
long after the blossoms have faded.
This plant blooms in the late afternoon and are open throughout the night or
can open in the morning on cloudy days. The flowers release a
musky aroma several hours after opening. This attracts hawkmoths,
the primary pollinator of these flowers. In the morning, bees may linger in the
floral tube, but they have little to do with pollination.
Native Americans have used the plant for dyes or medicinal properties,
both in prehistoric times and modern day. The Navajos boiled the flowers
to make a light brown or purple color for dying wool. The Hopis used
the roots of older plants to make a blood-strengthening tea for pregnant women.
Teas were also made to treat colic, eye infections, muscle soreness,
body swellings, rheumatism and indigestion. The Acoma and
Laguna Pueblo tribes dried the leaves for smoking material,
and some say the plant has a sedative property.
