Agave 'Royal Spine'
Agave 'Green Steel'
This hybrid is probably a cross between Agave macroacantha and Agave victorae-reginae 'Compacta'.
Agave 'Royal Spine', also known as Agave 'Green Steel', is an attractive small Agave with rosettes of narrow, steely-green leaves with dark, spineless margins and a dark terminal spine. The rosettes grow up to 18 inches (45 cm) tall and up to 2 feet (60 cm) in diameter. It may be the same plant sold as Agave 'Little Shark'.
How to Grow and Care
Light: These plants require full sun to part shade. If you are growing Agaves indoors, choose a bright, sunny window with as much sun possible. Agave plants love going outside from spring to fall.
Soil: Agaves will tolerate most soils as long as they have good drainage, but their preference is sandy or rocky soil.
Hardiness: Agave 'Royal Spine' can tolerate temperatures as low as 20 to 50 °F (-6.7 to 10 °C), USDA hardiness zones 9a to 11b.
Watering: Mature plants are very drought tolerant. From spring to fall, water thoroughly your Agave when the soil mix becomes dry. In winter, water sparingly about once a month. Plants in containers require more frequent watering than those in the ground.
Fertilizing: Give your Agaves a small amount of fertilizer in the spring during the first two years.
Repotting: When the pot becomes full of roots, it has become pot-bound. If you notice you Agave becoming pot-bound, repot it with new soil in a new pot that is just slightly larger than the old one.
Propagation: Since it can take years to produce seeds, Agaves are usually propagated by offsets.
Toxicity: Agave 'Royal Spine' is not listed as a toxic plant, but it may be mildly poisonous to children and pets.
