🌱 Morphology
   Intergeneric succulent hybrid with a rosette growth habit, resulting from the cross between Agave and Manfreda. ‘Moonglow’ develops a low, very open rosette, with leaves extended almost horizontally from the center. It can reach approximately 20–25 cm in height and about 50 cm in diameter.

The leaves are rigid, fleshy, and narrow, approximately 2.5 cm wide, with a smooth, silvery blue-green surface. They feature large, irregular dark purple to nearly black spots, exceptionally large for a Mangave and responsible for much of its characteristic appearance.

The leaves remain straight and flat, without the marked arching of other cultivars, forming a low, spreading rosette with a very graphic look. The margins have small, soft teeth, and the apex ends in a relatively soft spine, much less aggressive than that of many Agaves. The intensity of the markings increases with high exposure to UV radiation.

🌍 Distribution, habitat, and family
Family Asphodelaceae. ×Mangave is an intergeneric hybrid nothogenus between Agave and Manfreda, so ‘Moonglow’ does not correspond to a wild species and does not have its own natural distribution or habitat.

The cultivar originates from the ‘Bloodspot’ horticultural line and was selected for its leaf rigidity, silvery-blue coloration, and, especially, the exceptional size of its dark spots.

❄️ Temperature
USDA Zone 8–10. It tolerates minimum temperatures down to −12 ºC occasionally in dry conditions, according to the commercial hardiness zone assigned to the cultivar. However, this figure should not be interpreted as a safe cultivation temperature for a potted specimen: prolonged cold and, above all, the combination of low temperatures and humidity can cause significant damage.

In winter, it is recommended to keep the substrate dry or very slightly damp and to protect the plant from persistent rain and prolonged frosts. Walters Gardens recommends keeping Mangaves dry during the winter and avoiding prolonged cold conditions.

☀️ Lighting
Target DLI PAR: 20–30 mol·m⁻²·day⁻¹.

It requires very high light levels and can be grown in full sun after progressive acclimatization. Intense solar radiation, especially the UV component, promotes the expression of the large purple spots and the contrast between them and the silvery blue-green background.

With low radiation, the spots lose intensity and the foliage may take on a greener hue. When grown indoors during winter, the coloration may temporarily decrease and recover after several weeks of direct sun exposure.

💧 Growth cycle and watering
Winter dormancy. It maintains its growth mainly during the warm season, when temperatures allow for high metabolic activity. In summer, it appreciates water when actively growing, although it retains good drought tolerance.

During the active period, it is recommended to water thoroughly and allow the substrate to dry out completely before watering again. The substrate must have excellent drainage and never remain waterlogged.

In autumn, watering should be gradually spaced out. During winter, it is recommended to keep it dry, minimizing water intake while temperatures are low. Excess humidity during this time can promote crown and root rot.

🌸 Flowering
Like other Agave hybrids, ×Mangave can produce a long terminal floral spike when it reaches maturity. Flowering consumes the rosette's reserves, and after blooming, the specimen may complete its cycle, although the plant produces basal offsets that allow the cultivar to be perpetuated.

Flowering is not the main ornamental attraction of ‘Moonglow’, whose interest lies in the horizontal architecture of the rosette and its large purple spots.

🌿 Nutrition
During the active growth period, Desert CHOICE® Succulents is recommended, with a high content of potassium and bioavailable calcium, applied after watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering. During winter dormancy, fertilization is not recommended.
