One of the commonly confused pairs of Echeverias are Echeveria Chihuahuaensis and Echeveria Colorata.
Echeveria Chihuahuaensis Leaves
The Echeveria Chihuahuaensis leaves would be described as acuminate. This means that it is tapering with a point or it can mucronate, which means that its abruptly ending in a new crow or a pointed tip.
In addition, the Echeveria Chihuahuaensis also features a huge number of leaves given the small area that it occupies and it does not get too big. The most is about 20 or 25 centimeters (roughly 7-10 inches in diameter). For a mature Echeveria Chihuahuaensis, the markings on the tip look like it has balance or claws and this leads the nickname Cat’s Claw.
Echeveria Colorata Leaves
The Echeveria Colorata has bigger leaves, which makes the rosette look crowded. In terms of leaf shape, it can be acute which means it’s tapering or acuminate to be acute with a pointy protrusion of the tip.
As a side note, you’ll find this labeled as Echeverria Colorata fa Colorata or Echeveria Colorata “Lindsayana”. They are essentially the same plant as far as classification is concerned. There may be some differences, very subtle differences in terms of leaf shape and color. However, not enough variation to justify a separate sub species or variety.
Mexican Giant and Echeveria Colorata fa brandtii
There are other forms and varieties of the Echeveria Colorata. Firstly, there is “Mexican Giant“. It is the largest of the Echeveria Colorata bunch. It has a very thick farina and tends to be pale white and shifts to orange when it’s stressed.
Another type is the Echeveria Colorata fa brandtii. For both “Mexican Giant” and Echeveria Colorata fa brandtii, all of their leaves have the same basic shape. The leaves are acute so they go pretty much straight then taper off gradually. Unlike Echeveria Chihuahuaensis, which tends to be more mucronate than acuminate. The leaves go wide then abruptly ends.
The differences between the two would be a lot like the Black Knight and the black grapes. The key to recognizing the differences between these two species is knowing the difference between mucronate and acuminate.
