The new species discovered in 2001 (Kohinoor's standard for [new] is getting lower and lower)
classification:
Subspecies of perezdelarosae, the difference between the two is as follows
Andersoni:
Central spine short straight
Radical spine neat
flower white ~ light pink body
small ball
Perezdelarosae:
Central spine long hook-shaped-end
Radical spine disarray
flower pink ~
larger and columnar
Because there is another species called Fengming , and 120% of the novices and 90% of the professional sellers will not understand the difference between the two
place of origin:
There is only one growing place in the volcanic lava zone of Zacatecas, Mexico.
Habitat is barren volcanic rock . the volcanic rock that is as big as the mountain is cracked, many small pits of several meters are accumulated in the mountain and grow in these small pits. Water will accumulate in pits during the rainy season.
Appearance: Small cute cactus, cute is justice.
Zhou stabbed white, tightly arranged around each other, presenting a pure white surface with a black thorn. Some individuals' thorns will be arranged in a prismatic shape, so beautiful that there is nothing to say.
The fruit is small, 5mm large, hidden between the tubular . After maturity, it is dried and hidden behind the spine. The fruit must be clipped by hand and the fruit will not come off naturally.
It has some of the characteristics of the cryptocarpa cactus it also hide the fruit, but not as strict as the typical cryptocarpa cactus.
Cultivation feelings:
A small cactus that grows slowly. It has a habit like M. luthy but is more resistant to exercise. It is not as easy to root-rot as a M. luthy . There are no taproot.
My research on the soil of habits seems to be quite helpful. When I mix the medium, I didn't put the red akadama soil that I usually put, but I bought the volcanic stone to mix it. This recipe works well.
Like high temperature and strong light, like the soil to be completely dry. It doesn't matter if you don't water for a few weeks in summer. When water is scarce, it will be retracted into the soil, which is easy to spot. They will be obviously green up after drinking water, I will wait until the whitening shrinks before watering.
I mixed fertilizer into the water several times when I was watering, and I didn't see any effect.
The medium formula I used was: medium-sized particles with extreme drainage, no organic matter at all, a large number of volcanic rocks and volcanic minerals.
seed:
Seeds need medium temperature above 20C to germinate, and the germination rate is miserable.
Fresh seed germination is not high.
It may sprout in a few months, and the seeds sowed in December will be issued in March and will be sent again in May.
It is recommended to keep the potted seed without germination.
the seeds will suddenly germinate again later. it may take as long as 6 month.
medium:
I recommended to use Kiryu sand, black and white volcanic rocks and other volcanic rocks. When sowing, it is necessary to sieve about 5mm of fine particles to facilitate sowing,it is difficult to germinate with coarse particles.The seedling will have hard time coming out from craters.
