Rebutia (Weingartia) trollii
This is among the most vigorous
and earliest bloomers. Flowers are usually orange or red.
|
Description:
Weingartia (Rebutia) trolli is a heavy bloomer characterized by
bright orange to orange-scarlet flowers.
Stem: Usually solitary, globose to short cylindrical up to 10 cm
wide, 20 cm tall.
Ribs:16 to 18 tuberculate, often spiraling.
Central spines: 2 to 8 up to 2 cm long.
Radial spines: 16 to 24 yellowish with brown tips, about 1 cm
long.
Flowers: Usually orange or red (sometime dull yellow)
approx. 2-3 cm. long, 2.5cm in diameter, they are produced (unusually)
all over the body of the plant especially in a ring near the very tips
of the stems differing from other rebutias in that its flowers appear
very near the meristem as opposed to the lower, stem side and base
locations of those others. As well, on this and a few other ex
Weingartia species, one areole can produce up to 4 flowers.
Blooming season: The flowers are produced in early summer and
remain open for five or six days.

Note: All the 60 species of genus
Weingartia have been transferred to synonymy status under the
genus Rebutia; about 45 or so of them as synonyms of two
species, R. canigueralii and R. neocumingii.
The genus Weingatia was always considered difficult to
differentiate from Gymnocalycium, Neowerdermanniana,
and Sulcorebutia and its name has had a very eventful
history which evidently continues in controversy today.

This species blooms several times in one season.
Cultivation: Full sun to light shade, Water regularly in summer but
do not overwater. Keep dry or slightly moist in winter at a minimum
temperature of 5°C (But Hardy to -4°C or less).
It is better that they are repotted regularly. Repotting will increase
size of stems and the number of flowers produced. Repot yearly until
reaching about 100 mm in size, then every two or three years will
suffice. Repotting is best done at the end of winter but can be done at
other times. Do not water for a couple of weeks after repotting to
reduce risk of root rot via broken roots.
Propagation: Offsets (seldom available), or seeds
