This cactus from the category is very different from others and above all the unusualness of its thorns. It is also called a grassy cactus, a paper-prickled cactus. That is what attracted my attention.

The long, flat, brown (light brown) central spine is very similar to a dried blade of grass, and on a cactus it resembles a bunch of last year's grass, especially when the plant is in winter and the stem greatly reduces its size. By the way, this is one of the adaptive features that allowed the plant to survive as a species. This cactus really grows on grassy fields and undergrowths.

Sowing seeds (Mesa Garden) was carried out 10.25.06. Out of 10, there was only one seedling, which was immediately grafted onto Pereskiopsis. Seeds have a very large unevenness of seedlings, so they are recommended to re-sow for several years and, at the same time, subjecting to stratification, stimulating germination. The essence of stratification is the alternation of freezing (wet and dry) and sowing. Our patience was enough only for one cycle of such a process, especially since we did not receive other seedlings during reseeding.

The aspiration of the grafted Tumei upward was not at all pleasing, all the cacti at peresyopsis pass the children's period of elongation and immediately take on the appearance of an adult plant, but, as it turned out, Tumeya also has a very elongated appearance as an adult, as it grows in grass.

For some reason, our plant wasn’t going to kid, but the hand didn’t rise artificially forcing it to do it. By the end of the first year of my existence, I decided to transfer it to a hidden stock. And in the collection we got another same plant, which initially began to acquire side shoots, and material for breeding appeared.

The flowering of the first plant took place in September 2008, that is, after almost 2 years from sowing, which is quite a long time for vaccinations for peresyopsis. The flower was small in size about 2 cm in diameter and 2.5 cm in height with a characteristic brown middle on the back of the petal. Flowering lasted 3 days, the flower bloomed in the late afternoon and was in the open state for 3 ... 4 hours.

Unfortunately, the stump of pereskiopsis near Tumei has decayed. This became clear from the too high mobility of the scion. I had to pull the plant out of the pot, there was virtually no stock, but a small spine appeared on Tumeya itself, which inspired hope for the transition to its roots. But it was in the winter and rooting in the wet sand and the greenhouse gave further decay of the scion itself. Had to cut and root again. However, this process was unsuccessful. Having stood all the next summer on rooting, Tumeya simply dried up, but did not give roots.

In the summer of 2008, many vaccinations were made from the second plant, including two mother liquors, one of which was at pereskiopsis. There were no problems with the content of Tumei on the vaccine.

The next flowering occurred precisely on the mother liquor with pereskiopsis. The plant was removed from the winter house for further vaccinations, but having stood warm for a week, it gave a bud.

There was no choice but to give the plant bloom. And not in vain. The flower was very attractive and very different from the first. Firstly, it was significantly larger (4 cm in height and about 4 cm in diameter), and secondly, it was cascading, and the petals were located in at least three tiers.

The pistil was much larger than the first. I tried to stimulate self-pollination and, it seems, something happened ...

Sclerocactus papyracanthus (Engelm.) N.P. Taylor

Toumeya papyracanthus Britton and Rose

Echinocactus papyracanthus Engelm,

Single or group growing plant.

Stem: Elongated up to 20 cm, in diameter up to 2 cm, dark green, without ribs, tubercles slightly elongated. Areola hairy. As a rule, they have one (two) long central paper brown spines, sometimes there are 3 ... 4 of them. The new growth of these spines is red. Radial spines (6 ... 8) white are located on the stem of the plant, 3 ... 4 mm long.

Flower: It is formed on a new growth of the current season near the top of the stem. Whitish, bell-shaped, with brownish central stripes on the outside of the petals. Diameter of a flower is up to 3 cm. Flowering since April.

Fruits: Spherical up to 2 cm, prone to cracking when ripe.

Seeds: Black oval up to 2.5 mm.

Roots: Fibrous 5-10 cm long.

USA, Arizona, New Mexico, Texas, Colorado. Mexico.

It is quite widespread, but ecology and industrial land development reduce the populations of these plants.

Open grassy area or undergrowth. At an altitude of 1500 ... 2300m. The soil is loamy and sandy, sometimes with limestone.

Moderate watering during summer growth. They are prone to decay of the root system and death with excess moisture, especially after plant transplantation. Open sun with partial shade is required. The soil is breathable with a well-drained bottom layer. It tolerates frosts up to - 12 ° C.

Seeds have a very large uniformity of germination and require reseeding with stratification. Seedlings are prone to death, so cultivation on vaccinations is recommended.

1.2.Lighting

The plant prefers bright sunlight with a slight shade on hot summer days. In autumn and winter should receive maximum light. Good lighting stimulates the formation of buds. With a lack of natural light, fluorescent lamps can be used to illuminate.

Very difficult to maintain and capricious plants that can only be experienced by experienced cactus growers. When grown on their own roots, they are especially finicky.

1.9 Soil moisture

Water until the soil is completely saturated, but dry it at least half the depth before each subsequent watering. In winter, watering is minimized, the toumea will need watering if its stem begins to wrinkle. In the natural environment, these cacti during a drought are so reduced in size that they can completely hide under the surface of the soil.
