Agave titanota 'Black and Blue'

Agave titanota 'Black and Blue' key facts

Growing Difficulty

Intermediate

Lifespan

Perennial; the flowering rosette dies and offsets carry on

Size

Single rosettes about 30 cm across; 30-50 cm when fully grown

Watering

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

Light & Placement

Likes strong light and airflow; in poor light the leaves stretch, so indoors use an LED grow light and a fan.

Watering

Dislikes summer humidity, so keep on the dry side; in winter water about once a month.

Temperature & Winter

Tender; about 0°C is the minimum it survives. Winter it indoors in a sunny spot.

Soil & Repotting

Free-draining mix; divide offsets to propagate.

Notes

Many plants are tissue-cultured. Leaves tend to lengthen beyond 30 cm, so give plenty of light and air to keep it compact.

About Agave titanota 'Black and Blue'

Agave titanota 'Black and Blue' (B&B) is a compact titanota with pale blue-gray leaves and near-black teeth, selected from Oaxaca-collected seed. Suited to intermediate growers, with rosettes reaching roughly 30 to 50 cm across at maturity.

7 things to know before growing Agave titanota 'Black and Blue'

1. 1Light & Airflow

   Agave titanota 'Black and Blue' thrives with strong light, so give it the sunniest spot available, whether outdoors or by a bright window. Good light brings out the contrast between the blue-gray leaves and near-black teeth. Poor air circulation can lead to rot, so avoid cramped, stagnant spots.

2. 2Water Sparingly

   The thick leaves store water, so let the soil dry out completely before watering again. Overwatering is a common cause of root rot, so stretch the intervals between waterings even further during cooler months.

3. 3Fast-Draining Soil

   Use a well-draining succulent or cactus mix. Adding drainage material at the bottom of the pot also helps prevent water from pooling around the roots.

4. 4Repot as It Grows

   Mature rosettes can reach 30 to 50 cm across, so plants need to be moved into larger pots as they grow to avoid becoming root-bound. Repot during the active growing season and handle the roots gently.

5. 5Cold-Weather Care

   If grown outdoors, move the plant under eaves or indoors when frost or sudden cold snaps are expected. Cut back on watering even further in cold weather and keep the plant on the dry side to prevent damage.

6. 6Flowering & Renewal

   This is a perennial plant, but each rosette dies once it flowers. Offsets that form around the base carry the plant forward, so the clump renews itself through its pups rather than the original rosette.

7. 7Choosing a Healthy Plant

   Look for a rosette with a clear contrast between blue-gray leaves and dark, near-black teeth, since that's the hallmark of this cultivar. Leaves free of damage or discoloration, and a base that feels firm rather than loose, are good signs of a healthy plant.

Frequently asked questions about Agave titanota 'Black and Blue'

Q.Is this agave suitable for beginners?

A.This cultivar is generally considered suited to intermediate growers. Getting the light exposure and watering right takes a bit of know-how, so it works best for someone with some prior agave experience or who's willing to research the basics as they go.

Q.How big does it eventually grow?

A.A single rosette typically stays around 30 cm across, though mature plants can reach 30 to 50 cm in diameter. It's worth factoring in that eventual size when deciding where to place it.

Q.Where does the name "Black and Blue" come from?

A.The name refers to the pale blue-gray tone of the leaves paired with the near-black teeth along their edges. It's often shortened to "B&B."

Q.Can it stay outdoors through winter?

A.It depends on your climate, but moving the plant under eaves or indoors is advisable whenever frost or hard cold is expected. Cut back on watering during cold weather and keep it on the dry side.

Q.What happens after the plant flowers?

A.Once a rosette flowers, that rosette will eventually die back. Offsets that form around the base before or after flowering carry the plant forward, so raising those pups keeps the clump going.
