Type 5 - Prickly Pear Cactus. Branches have round or cylindrical sections that drop off easily and become rooted.
This group of plants is characterized by a sectional
growing habit, in which each section can be round like a pancake or
cylindrical like a section of pipe. The newest sections are very
loosely attached, fall off easily, move around, and may eventually
become rooted into the ground. The older sections at the base of the
plant become ridged and act as the supporting trunk.
Names and distribution: This group of plants is the
largest in terms of numbers of species and geographical distribution.
It includes thousands of species and it's range spans most of North and
South America. It's range spans from Canada to Patagonia. Many species
have even become naturalized in other parts of the world. Most of the
species are within the Opuntia family, but there is also Maihueniopsis,
Puna, Tacinga, Tephrocactus, Tunilla, Austrocylindropuntia,
Cylindropuntia, and Grusonia.
Flowers: Many species in this group have spectacular
flower displays mostly in the spring and summer. Quite a few species
have bright yellow flowers. However, various shades of pink, red, and
orange are not uncommon. Some species have inconspicuous flowers that
are typically mixes of green and yellow or green and red. And a few
species have brightly colored fruits that follow the flowering, such as
the Christmas Cactus.
Spines: This group of plants have spines that differ
from other cacti. Some have spines that are straight, but the tip of
the spine is barbed. When it pokes an object like you clothing, it
hooks in and is tough to extract. In fact, the more you tug on it, the
deeper it goes in. The other type of spines are called glochids. They
are very small like saw dust and dry ones can float freely in the air
when the plant is moved. The glochids are grouped in small packets of a
hundred or more and when touched, the entire packet will inject itself.
These two types of spines make this group of cacti the most
uncomfortable and memorable of all cacti. There are many techniques for
removing the spines that get passed around like folklore from those
people working in the trade. For the straight barbed spine, rather than
trying to pull it straight out, try to figure which side of the tip is
barbed, then try to twist the spine and unhook it like unhooking a fish hook
from a fish. For the glochids, use a double edged shaver, and just
scrape over the area that has the packet injection. The glochids will
come out redily.
Common Names: There are many regional common names
typically derived from the shape of the plant or ones close encounters.
Some are named after animals: "Beaver Tale cactus", "Teddy Bear
Cholla", "Buckhorn Cholla", "Cow's Tongue", or "Owl Face Opuntia".
Others are named after other objects such as "Peanut Cactus", "Prickly
Pear", or "Thumb Buttons". Still others are named after people or
places: "Santa Rita Cactus", "Mini Rita Cactus", or "Indian Fig".
