Echeveria LONGISSIMA 'AZTATLENSIS' - Long-stemmed echeveria 'Aztatlensis', Echeveria longissima 'Aztatlensis', Hen and Chicks.
Echeveria is a large genus in the stonecrop family (Crassulaceae), comprising about 150 species of succulent perennials distributed in semi-arid regions of Central America, Mexico, and northwestern South America - from Texas to Argentina. The center of species diversity is concentrated in Mexico. Most species inhabit rocky slopes, screes, dry canyons, and mountain plateaus with good drainage and intense lighting.
Echeverias are evergreen rosette succulents without a true stem or with a short leafy stem. The leaves are fleshy, with a waxy or powdery coating (farina), ranging from rounded to lanceolate, often with a colored tip or margin. In many species, lateral offsets are formed over time, earning the plants the popular common name "hen and chicks". The plants are polycarpic - blooming and fruiting repeatedly throughout their entire life.
The inflorescence is a single- or many-flowered winding cyme on an arched peduncle rising from the center or base of the rosette. The flowers are tubular, nodding, usually in shades of red, orange, or yellow, pollinated mainly by hummingbirds and insects. The fruits are small follicles, and the seeds are tiny and numerous.
Echeveria longissima is a succulent with pronounced vertical growth, forming rosettes on an elongated stem and acquiring a more "palm-like" silhouette over time. The leaves are fleshy, elongated, spatulate or narrowly spatulate, with pointed tips, arranged in a spiral, forming a relatively loose rosette. Leaf coloration is green or glaucous-green, often with a waxy coating; under bright light, margins and tips can turn pinkish or reddish. With age, the stem becomes bare at the bottom due to the natural shedding of older leaves.
Flowering occurs in spring or summer. The tall peduncle rises above the rosette and bears a raceme of bell-shaped flowers, most often orange-pink or coral, sometimes with a yellow hue inside. Flowers open sequentially, so flowering can last several weeks. After flowering, fruits with tiny seeds form.
Echeveria longissima is remarkable for combining a rosette form with a more upright, "columnar" growth habit, making it distinct from most compact echeverias. In collections, it is often kept as a plant with an expressive silhouette, and in arrangements, it is used to provide height among lower rosettes.
