Mammillaria luethyi
|
|
Description: M. luethyi
is a very tiny plant, but by far one of the most spectacular members
of its genus, distinctive when not in flower because of the
'spination' (if it can be called that!) at the tips of the
tubercles, and even more magnificent in flower.
Growth Habits: Solitary or clustering.
Stem: 1.5 cm in diameter.
Spines: Short, soft and white, not prickly.
Root: Fleshy
tap root.
Flowers: Large, rich magenta with a white throat.. This plant had long been
known from a lone photograph by Boke, published by Bravo & Sanchez
Mejorada, of a cultivated plant of unknown origin. It was rediscovered
in habitat in 1996 by George Hinton and Jonas Luethy, and published by
Hinton in January 1996.

Cultivation:
The plant is often seen
grafted,
as most of the available stock has so far been propagated this way.
Grafted plants grow fast and are very
floriferous.
But it is relatively easy to cultivate plants on their own roots and
no special care required, at least given the same care with drainage and
watering that is afforded to other species of Mammillaria with
fleshy roots.
The luethyi needs
full sun!!!
Poorer
luminosity levels
produce a green anaesthetic plant with open, far and wide spaced
areoles.
Cuttings
root very well but plants on their own roots are quite slow.
