Interesante pregunta...nunca he visto a la venta en España esta bella especie. ¿Tu tienes algún ejemplar?
Hola Mar 484 En su cultivo de Palmpedia dice quien la multiplico y quien la vende lee lo que sigue: "I have grown this palm for over 20 years now. I bought it years ago at a palm sale at Fairchild gardens. I distributed many seeds over the years to numerous people including Jeff Marcus. Dale Holton bought almost all of the plants from Marcus and had the plant identified. Dale has had them available for sale in the past as he has seeding plants that he keeps in his nursery cycle. The plants will continue to clump over the years getting quite large at the base. The leaves become very curly and exotic looking as they get older. I always get comments about the plants from visitors. They are difficult to tell from an arenaria when young. As they get older they become more upright than an arenaria. They typically get about 7-8 feet overall height. They seed a lot more than arenaria. Their seed pods also are larger than an arenaria. About 17 years ago I gave several one gallon plants to my sister that lives at the beach in st. Augustine Florida 9a. I live in west palm beach which is where I started growing the plants. Despite total neglect at my sisters they are growing and doing fine. They have survived many very cold winters over that time. About 15 years ago I bought a house down the street in st. Augustine. I have had five plants growing at the beach for about 15 years. The coldest temperature I am aware of is mid-20's. The plants survive that without a scratch. I mean no burn at ALL. The only damage I have had to any of the plants was when we had the very cold winter a couple of years ago I had one totally unprotected from the northwesterly wind. The winds were extremely strong with temps in the 20's. That one plant lost one of its clusters. The plant survived without any other issues. All of the other plants were unscathed. Because the plants stay short they don't get up into heavy winds. I grow them in full sun. They do not grow as good in shade of any kind. They like water but not excessive amounts. I would say average to slightly more. Fertilize normal amounts. I am also growing arenaria, leucocalyx and the other species the name of which escapes me as I type this. All in st. Augustine. I have had arenaria there for years as well. The other two species have been there about five years. They are all flowering but I don't know if the young plants have set seeds in addition to flowers. They all prefer more sun than less. They are all cold hardy so far to the high twenties. Because of their dwarf growth habit they are protected from the cold winter winds which do the most damage." (Richard Briscoe) En paginas de Internet de Viveros de Palmeras de Europa no la vi a la venta quizas la puedas conseguir en Viveros de Palmeras de USA. Yo en mi campo pegado a la costa del gigantesco Rio Parana en Provincia de Corientes tengo una coleccion de 250 especies de Palmeras y entre ellas tengo las Allagoptera Arenaria y Allagoptera Caudescens que tambien son hermosas especies y son las mas vendidas en los viveros de palmeras. aqui te muestro como crecen enmi campo las 2 especies de Allagopteras que yo tengo porque en especial la Allagoptera arenaria es muy pareciada a la Allagoptera breviccalyx : Allagoptera Arenaria formo 3 troncos este es el ambiente que la rodea de selva humeda con el suelo de arena cubierto de helechos tuve que hacerle armazon de Bambus nativos en mi campo para sostenerle las hojas muy largas y pesadas que sin el armazon se doblaban y se apoyaban sobre el suelo ahora que dieron semillas voy a tratar de germinarlas para hacer plantines y sembrar esta hermosa especie en otras zonas de mi campo. esta es foto desactualizada de varios años atras ahora en el 2020 estan mucho mas gruesos y altos los troncos . Allagoptera Caudescens antes del cambio de nombre se llamaban Polyandroccos caudescens esta es una foto de Internet de un ejemplar adulto y como se puede ver es la unica especie del genero Allagoptera que forma troncos altos A continuacion las criadas en mi campo. aqui uno de mis 3 empleados midiendoles las hojas con un metro de 2 metros de largo forman hojas de casi 4 metros de largo y de mas adultas con tronco son mas largas todavia. por abajo de las hojas toman color verde glauco plateado y por arriba de las hojas son verde fuerte aqui se observa el raro formato de los foliolos de las hojas separados 20 a 30 cm sobre el raquis de las hojas aqui el formato de las hojas cuando son plantines mas chicos Te deseo que puedas encontrar algun vivero que te venda las Allagopteras bervicalyx y te mostro las fotos de las otras 2 especies de Allagopteras que tengo en mi campo para que apobreches a comprarlas tambien porque son muy lindas y poco vistas en Jardines Saludos. Erwin.
