Corifanta - Coryphantha vivipara


GeneralitŠ°


this plant is native to North America; to the genus belongs about sixty different species. Originally this plant was listed as belonging to the genus of the Mammilarie, with a number of species that barely reached thirty. The origins of the name Coryphantha derive from the Greek: koriphe - summit, anthis - flower = plant that bears the flower on top.
Morphologically the plant is very similar to the mammilaria, it has stems that vary from globose to cylindrical, which can measure from three to 15 cm, depending on the species. On the stem there are numerous tubercles at the end of which there is the thorny areola.
In the summer period usually large flowers sprout, the color can change according to the variety, usually it is yellow or orange. The flowers are funnel-shaped and have an ovary inside them that varies from species to species.

Exposure




the plant needs mild temperatures, which is why in our area it is advisable to keep it indoors or in a greenhouse. In winter it is necessary to winter the plants in temperatures that are around 7-8 ° C, this to allow them a period of vegetative rest, to induce the plant to a new flowering.

Watering


As almost all the succulents need little water and cannot stand water stagnation, it is advisable not to wet the plant for the entire winter period.
With the vegetative restart, towards April begin to water. The administration of specific fertilizers is appropriate only from May until August, do not fertilize in the cold months. The Coryphantha is usually exposed in bright areas and with a discreet ventilation, in the hottest periods the plant can be taken outside in full sun.

Multiplication


The plants are multiplied by removing the small seedlings that grow at the base of the generating stem, this operation is performed in the warmer months, or from seed, the sowing must be carried out in the spring months.

Pests and diseases


The corifanta is a succulent plant that needs a temperate climate and needs to grow in well-drained soil. Water stagnation and excessive watering must be completely avoided because they could cause serious damage to the plants. Water stagnation is in fact the first cause of mold and root rot and is a frequent problem when plants are grown in apartments where temperatures are not very high and therefore the evapotranspiration of the soil is very limited.
First of all, we use a well-drained soil as a breeding ground and second, we do not overdo watering and water because too much water could cause serious problems in these plants.
For the rest, there are no particularly dangerous diseases or pests to report to these plants, which on the whole do not have large enemies that can undermine their development.
