Agave 'Blue Glow' key facts

Growing Difficulty

Perennial; the rosette dies after flowering

Size

About 60 cm tall and 90 cm wide; leaves about 45 cm long

Watering

Light feeder; a little slow-release fertiliser in the growing season is enough

Light & Placement

Full sun to part sun; placing it where it is backlit shows off the red and yellow edging.

Watering

Drought tolerant; needs little water. Water after the mix dries.

Temperature & Winter

A US grower rates it to at least about -7°C, with reports of it unharmed around -9°C; potted plants are safest wintered away from frost.

7 things to know before growing Agave 'Blue Glow'

1. 1Give It Plenty of Sun

   Blue Glow colors up best with plenty of direct sunlight outdoors. If grown indoors, place it in the brightest spot you have rather than behind a sheer curtain.

2. 2Water Sparingly

   Thanks to its succulent leaves, Blue Glow tolerates dry conditions well — water thoroughly only after the soil has dried out. Growth slows in winter, so space out watering even further during colder months.

3. 3Use Well-Draining Soil

   Choose a cactus and succulent potting mix to prevent root rot. If planting in the ground, avoid low spots where water tends to collect.

4. 4Repot Only Every Few Years

   Because it grows slowly as a single rosette, Blue Glow doesn't need frequent repotting. Move it up to a slightly larger pot once roots start showing through the drainage holes.

5. 5Protect It in Winter

   Blue Glow has some cold tolerance, but hard frost or prolonged freezing can damage the leaves. In colder regions, bring it indoors or move the pot somewhere sheltered, such as under eaves, during winter.

6. 6Check for a Healthy Single Rosette

   Since Blue Glow rarely produces offsets, look for good red-and-yellow coloring along the leaf edges and a healthy growing point at the center when choosing a plant. Pick one with undamaged leaves and a tightly formed rosette.

7. 7Flowering Signals the End

   Like other agaves, Blue Glow dies after it flowers. Because it grows so slowly, it rarely blooms, which means most growers get to enjoy its foliage for many years.
