Sago palms, native to southern Japan, are not actually true palms but are referred to as such due to their similar look. They produce stiff, dark green, glossy fronds that grow from its short, shaggy trunk. The trunk is very low in young plants, possible even subterranean, but the trunk could grow up to 20 feet tall. This may seem like a poor choice of palm for a small houseplant, but they’re incredibly slow growing and could take up to 100 years to achieve that height. The sago palm is toxic if ingested so this plant may not be ideal if you have pets who might like to nibble on your greens.
