Most Likely Cross Between C. hildae and either C. latifolia or C. robusta.
Example of "Leaf Tip Burn" Most Likely Caused by Salt build-up in Soil or Going to dry Between Watering.
Ceratozamia hildae is arguably the most unique species of the genus Ceratozamia, and of cycads in general. It is often referred as the "bamboo cycad". Its upright stems with "multi-grouped" leaflets look very much like a bamboo plant. C. hildae originates from the San Luis Potosi and Queretaro regions of Mexico. It grows in Oak Forests, mostly in part sun and shade. Leaves grow upright to 6' feet tall (shorter in sunny locations) with multiple clusters of leaflets. Usually these clusters are in groups of three. Stems are short, usually at ground level, and eventually suckering at the base. New leaves can emerge in light green or bronze coloration. Leaf petioles have few to many spines. Cones emerge in early spring.
Ceratozamia hildae is a easy to grow cycad. It seems to grow best with partial sun and well drained soil. Be careful not to let it dry out. C. hildae also is very prone to "leaf tip burn", which usually is a result of salt build-up in the soil. Irrigating with purified water or regular deep waterings can help to minimize this effect. C. hildae can tolerate some frost, but best if planted with some cover for protection.
C. hildae is a nice small sized cycad which works well in many landscape situations. It is also makes an excellent container specimen.
