Agave victoriae-reginae, Queen Victoria's agave
Named after Queen Victoria, Agave victoriae-reginae ruled northeastern Mexico and the Chihuahuan desert. Although the plant is on the brink of extinction in its natural habitat, it thrives in rock gardens and succulent collections.
How to recognize Agave victoriae-reginae, Queen Victoria's agave?
A succulent perennial with a bushy, rounded habit, Agave victoriae-reginae grows to no more than 50 cm in height and 40 cm in diameter.
Queen Victoria's Agave is aculeate. The plant forms a compact, regular rosette of leaves. Its rigid triangular leaves are crowned by a brown spine. The dull green blades are accented with white stripes.
Unlike swan-necked Agave (Agave attenuata), which can flower every year, Agave victoriae-reginae is monocarpic. The plant flowers just once in its life, then produces offshoots and dies. The yellow or cream flowers appear in panicles at the top of a five-metre flowering spike.
Queen Victoria Agave is toxic to animals if ingested. Its sap is also irritating if it comes into contact with the skin. Keep pets away from your fat plant, and wear gloves when repotting. They'll also protect you from the stings!
Our maintenance tips
Agave victoriae-reginae are low-maintenance plants. However, they are sensitive to cold and excess humidity. Unless you live in a region with dry, mild winters, grow your plant in a pot. You'll then be able to bring it in before the first frost.
Watering
Agave victoriae-reginae plants need copious watering when the soil is completely dry. To know if your plant is thirsty, look at it: when it lacks water, its leaves change appearance. They become hollow, wrinkled or point downwards.
Water with room-temperature water, preferably non-calcareous, until the substrate is saturated with water, then allow the plant to drain before replacing it. Don't forget to drain off any water stagnating at the bottom of the planter or saucer. It could rot the roots.
Spray
Agave victoriae-reginae grow in arid regions and do not like humidity. No need to spray them.
Repotting
Every spring, repot your Agave victoriae-reginae to give it more space.
Obtain a pot with holes deep enough to accommodate the roots of your Queen Victoria Agave. Preferably use a terracotta model to ensure even drying of the potting soil after watering.
Pour a drainage layer (clay balls, gravel, etc.) into the bottom of the pot to allow excess water to drain off, followed by potting soil. Choose a light, well-draining substrate, such as a mix for cacti and succulents, or ordinary potting soil with sand. Plant your Queen Victoria Agave in the center and add soil. Stop a few centimetres from the edge and tamp gently to remove air bubbles.
Wait a few days after repotting before watering. The potting soil is already damp and agave victoriae-reginae do not like excess humidity.
Fertilization
To promote the growth of your Agave victoriae-reginae, apply fertilizer in spring and summer.
Add cactus and succulent fertilizer to watering water.
If you're repotting every year, there's no need to add fertilizer. Your plant will find sufficient nutrients in its substrate.
Prune
To encourage the growth of your Queen Victoria Agave, prune regularly.
Cut dry leaves with clean, sharp pruning shears.
Plantation
When the risk of frost has passed, it's time to plant.
Your Agave victoriae-reginae loves light and hates humidity. Plant it in the sun and in a place where water won't stagnate after a shower, such as an embankment or the top of a slope.
Dig a hole twice the size of the root ball. Place pebbles or clay balls at the bottom to improve drainage. Plant your Agave victoriae-reginae and fill in with garden soil. You can add sand to lighten the soil. Press down to remove air bubbles.
Cutting
Cutting is carried out during the strong growth phase, generally in spring and early summer.
The mother plant produces shoots. Separate them with a clean knife. Leave to dry for 24 to 48 hours in the open air, until a wedge forms at the base.
Pour a light, well-drained substrate into a pierced pot. You can use potting soil for cacti and succulents or a mixture of ordinary potting soil and sand.
Plant your cutting, burying the first two centimetres in the soil. Place the cup in partial shade.
Wait ten to fifteen days for the cuttings to root before watering.
