an impact on the landscape or even dish gardens.
Growing Cactus That is Blue
Feeling blue? Then try growing blue cacti. The sharp hue of
these plants creates drama in the garden. There are many blue cactus types that
offer some interesting difference of color combined with diverse forms and
brilliant flowers.
Why are some cactus blue? The thought is that it is some
sort of adaptation the plant has developed. Cactus
plants are among the most adaptive plants known and have evolved all sorts
of interesting coping mechanisms to survive in harsh environments. Blue tones
may have evolved to protect the plant from sun or help deter certain pests. No
one knows for sure exactly, but the color is not often found in nature and
provides the gardener an opportunity for some astounding color combinations.
Blue Varieties of Cactus
If you want to try growing blue cacti, the challenge is to
find one that suits your needs. There are big blue cactus types for the garden
and smaller species that are better suited to indoor containers. Most blue
cactus are desert varieties, meaning they should be outdoors only in southern
regions or used as indoor plants for northern gardeners.
Some large types include:
- Pachycereus Elephant cactus – The ribs of many Pachycerus cacti are blue-green in color.
- Cholla cactus – Cholla cactus, like the chain fruit cholla, is grown in the south and southwest United States, and is a fuzzy blue.
- Opuntia – Some varieties of Opuntia cactus have distinctly blue skin leaning to a purple blue.
- Cereus Column cactus – Column cactus has an upright growth and definite blue skin.
- Pilosocereus – A Brazilian species, Pilosocereus, also known as tree cactus, is really powder blue!
If you want to grow an indoor cactus that is blue, you could
choose from these options:
- Agave – A classic that comes in various sizes, agave is noted for its rosette form.
- Bishop’s Cap – Bishop’s cap is a small chunky cactus with no discernible stems in a five-point star form.
Since indoor cacti are bred with numerous interesting traits
to draw in consumers, blue varieties in smaller plants are not as rare and are
actually too numerous to mention. Go to your nearest home improvement or garden
store and you will find many standard and grafted
types from which to choose.
Notes on Blue Cacti
Many of the bluest varieties come from Brazil. They are
among the most cold sensitive varieties. They love extreme heat and full,
blazing sun. Always make sure the soil they are planted in is a bit gritty and
drains well.
These cacti types don’t need excessive nutrients in the soil
and are easy to manage, with minimal water requirements. The blue notes really
stand out among your regular green plants and draw the eye to such colorful
specimens.
