Remarks: Do not confuse

The glaucous (blue grey-green) appearance of this barrel with the nice
light orangish areoles makes it very easy to identify.
Cultivation: Plants are
slow growing to start but are easy to grow and require little care once
they have reached a nice flowering size. F. glaucescens is suited for
any rich, well drained soil in full sun throughout the year. Pot culture:
grow best in a fairly roomy, well-drained container filled with a porous
cactus soil mixture that doesn't contain too much humus. To
robust plants water and fertilize during the aestival growth cycle, this
plant need plenty of water (indicatively: about once a week) But
it is necessary to avoid wetting the bodies of these plants while they are in
sunlight. A wet cactus in the sun light can cause sun burning, which can
lead to scars or even fungal infections and death. In winter keep
completely dry at 10°C. This usually aids in maintaining a healthier
plant, but it can tolerate sporadic light frost.
Propagation: Seeds are the typical way
of reproducing. These cacti will easily grow from seeds and some from
