Echeveria coccinea forma
cristata (San Bartolo Co.
Hidalgo, Mexico)
Great succulent with attractive very fuzzy leaves that feel to
the touch like a cross between felt and velvet.
|
|
Easy to grow and perfect for pots, it forms fun shaped silvery,
leaf rosettes at the ends of reddish-brow velvety branches and seems to
to change in and out of its crested mode during the years. |

Description (of standard form): Succulent
rosette forming shrub, up to 60 cm tall or more that tends to branch at
base. Upright at first, its stems become prostrate and root into the
soil to form a spreading mound. The plant is soft-pubescent except for
the inside of the flowers. The species is somehow variable in habitat
and in cultivation too, comparable plants labelled E. coccinea
vary considerably in stem and leaf shape depending on clone and growing
condition.
Stems: Sparsely branching, 0.5-2 cm in diameter greyish or
reddish brown, finely grey-pubescent like the rest of the plant.
Aerial roots: This species produces lots of thin hair-like aerial
roots from the older part of the stem.
Leaves: 3-12 long,2-4 cm wide, in rosettes, and alternate and
scattered on the flowering stems, oblanceolate to obovate-spatulate,
narrow, tapered, upper face concave, soft dark green often redden
velvety with a covered in fine silvery fuzz giving the leaves a
blue-green colour.
Rosettes: Open, 5-20 cm in diameter.
Flowers: Abundant, in axillary long leafy simple spike
inflorescence about 35-70 cm tall. Scarlet or reddish/yellow outside,
yellow within. The flowers have a 5-parted corolla not longer than the
spreading calyx. Sepals ascending to widely spreading, 13-15 mm long,
calyx scarlet, sharply pentagonal 9-15 mm long, 8-9 mm in diameter at
the base and 7-10 mm in diameter at the mouth.
Pedicel 2 mm long They last well when cut.
Blooming season: Flowers in spring.

Family:
Crassulaceae
Scientific Name:
Echeveria coccinea forma cristata
Scientific name:
Echeveria coccinea (Cavanilles) De
Candolle
In: Prodromus S.R.V. 3:401, 1828 [Mar 1828]
(Rose, J.N. Sep 1903. Bull. New York Bot. Gard. 3: 5. )
De Candolle introduced the genus Echeveria by
naming Echeveria coccinea as the
type species.
Type :
Lectotype: E. coccinea (Cavanilles) A. P. de Candolle (Cotyledon
coccinea Cavanilles)
Origin: Mexico (Hidalgo)
Etymology: The genus Echeveria is named after the 18th
century Spanish botanist Atanasio Echeverria Codoy.
The species name “coccinea” comes from “coccineus” =
“red” refering to the petals that are yellowish-white at the base
and red (coccineus) at the tips.
Synonyms:
- Cotyledon coccinea Cavanilles
1793 (Basionym )A
- Echeveria pubescens Schlechterndal 1893
- Cotyledon pubescens (Schlechterndal) Backer 1869
- Echeveria longifolia

Crested form: The rare crested form produces magnificent, fun
shaped silvery, leaf rosettes at the ends of its reddish-brow velvety
branches and seems to to change in and out of its crested mode during
the years. |
Normal shoots may be removed.
Cultivation: Echeveria are
easily grown succulents that can tolerate sun, shade, moist soils, dry
soils, but look their best only when given adequate light levels and
water, and ideally should be grown outdoors in full sun. Generally
speaking, the more light a plant gets the better it will display its
colours and shape. Bright light is required to prevent "stretching" of
Echeverias ("stretching" occurs when a moderately fast growing plant
such as an Echeveria, is grown in dim light or over-fertilized, which
causes overly lush growth that contributes to weak, pallid plants).
However, when moving plants from lower light conditions into full sun,
be wary of sun scorch resulting from too rapid a transition into intense
summer sunlight, most easily avoided by ensuring plants are well-watered
before moving them on a cloudy day. Echeveria are able to tolerate
extended dry periods and survive drought without the need for watering,
but they will grow stronger if they receive adequate moisture during
their growing season, but never allowing the plant to remain waterlogged
(root rot sensitive). For this reason, it is essential in cultivation to
use a very porous soil, which will allow quick drainage. Avoid overhead
watering under humid conditions, especially during winter. Echeveria are
shallow rooted plants, and therefore benefit from good levels of organic
matter in the soil. Give it enough root space for optimum growth. Slow
release fertilisers with a low to moderate nitrogen content incorporated
into the potting mix are usually adequate for the spring and summer
growing seasons of Echeveria, and additional fertiliser applications
would not normally be required until spring. Good air movement is
important for minimising pest and disease risks, and avoiding excessive
humidity in cool winter conditions is important to successfully growing
Echeveria in the nursery environment. Can tolerate light frosts.
however, the ideal temperature range during the summer growing season is
5-25°C, with the cooler autumn temperatures tending to make their
foliage colours become more intense than those of the active summer
growing season. Aphids like this plant (and all flowering Echeverias).
Propagation: It is easily propagated by cuttings in the spring.
When the stem becomes too tall, just cut the top
rosette with a piece of stem and plant it. It will soon take root, while
the plant left with just the stem will soon grow new buds that can be in
turn used for propagation. Time to take cuttings: April to July. It may
also propagated by
leaf propagation. If the plant is
repotted some of the bottom
leaves can be removed, in order to attempt propagation.. However some of the
cuttings will dry out without producing a
plantlet.
Echeveria coccinea also forms a good stock for dwarf-growing
species.
