This palm has produced seed for me in San Antonio, Tx. They have been on the plants for two years and the seed coat is still greenish grey and has a bit of fleshiness. I plan to harvest and plant a few soon.

The seeds of this palm have been very difficult for me (and everyone else I've talked with) to germinate. I'm happy with the 10% I've been able to get. My oldest are now about 18 months old, and still have green strap leaves. I'm actually pretty surprised how quickly they've grown, producing about 7 or 8 leaves in this time and filling a 1 gallon container with roots.

Very sought after specimen palm for small, open gardens. This pricey little palm has recumbent trunks and suckers so it doesn't take up much room. It's most striking feature are it's nearly white leaves making it really stand out in the landscape. There are small teeth along the petioles. It is a very slow growing palm and specimens worth showing are often decades old or older. As a seedling, it is nothing to look at as the leaves are still greenish grey for many years before developing the silvery coloration. It is extremely drought and wind hardy.

So far no plants in cultivation have produced any seed, so if seed it to be had, it's from the native plants in Mexico... another reason this plant is so rare in cultivation
