Ceratozamia hildae, from Mexico, is probably the best cycad in this genus for landscape purposes. It prefers to be in partial shade, but can grow in deep shade. If grown in full sun, it will grow well but will get a little washed out looking. During a freeze with a low of 14F, these plants were not damaged. They react very well to fertilizer applications, and I have had these mature as early as 41/2 years from seed. This is my favorite cycad in my collection.
