Agave schidigera 'Shira ito no Ohi', also known as Agave filifera subsp. schidigera 'Shira ito no Ohi', is a slow-growing succulent with an attractive solitary rosette of dark green leaves with creamy-white margins, curly white hairs, and sharp, reddish terminal spine.

How to Grow and Care for Agave schidigera 'Shira ito no Ohi'

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 schidigera 'Shira ito no Ohi' can withstand temperatures as low as 15 to 50 °F (-9.4 to 10 °C), USDA hardiness zones 8b 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.
