Sago palms, known botanically as Cycas revoluta, are not palm but cycads that were growing on earth at least 200 million years ago, according to Texas A&M University. The plants are long-lived, hardy and slow-growing, making them valuable in the landscape. Sago palms are either male or female, with the female plants producing pollinated seeds in the late summer or fall. When mature for harvest in the spring, the female flower will open fully, exposing a cluster of round to ovoid red or orange seeds that fall in size between a large gumball and a ping pong ball.
Don gloves and harvest the mature sago seed from the plant by plucking them free.
Test the health and viability of the seeds by placing them in a glass of water. Those that sink are good and should be planted, while those that float should be discarded.
Remove the outer seed coat with your gloved hands to protect you from the plant toxins.
Bury the seeds in fresh potting soil or sand. Orient the seed horizontally with the pointed end facing sideways and bury an inch deep in the soil so that the top of the seed is at the soil line.
Water the seed in well and keep the soil lightly moist at all times. Place the pot out of direct sunlight and refrain from feeding the seed. Allow several months to pass, keeping the soil moist but not wet, and the seed will sprout.
