Wildflowers
are in full bloom all over the countryside and more so this year than
in the past because of the recent rains. I took this photo on February
4, 2005 near the old Gillespie Dam on the Arlington Valley birding
trip.
The
Scorpionweed is also known as Common phacelia, caterpillar weed and
scalloped phacelia. The name Scorpionweed refers to the curling
flowerhead that resembles a scorpion’s erect tail. This plant is from
the Waterleaf Family and there are 38 species of Phacelia in Arizona.
The weed normally is around 18” high, but can grow to 3 feet. This
particular plant was almost that tall. The flowers are violet-purple,
bell-shaped, with 5 rounded, united petals about ¼” wide in
finely haired terminal coils. The stalk is branched, dark green and
covered with hairs. The leaves are elliptical. Caution – the
gland-tipped hairs can cause a severe rash to some people. The flowers
bloom from February-May below 4,000 feet. It’s an annual that grows on
roadsides, sandy washes, desert flats and small hills.
When
you are out and about, take the time to look at the beautiful panorama
of flowers that are currently blooming. It’s a treat for the eyes.
