The Areca Palm, or Dypsis lutescens (formerly Chrysalidocarpus lutescens), is a great palm for a tropical splash in the summertime on home patios and building entrances in northern climates.  It can also thrive indoors, but it takes a lot of light for that to happen, and it’s highly rated for cleaning indoor air.  Also known as the Butterfly Palm, because of its arching yellowish-green fronds, and the Party Palm, because it’s widely rented for weddings and parties, this less-expensive cousin of the Kentia Palm is a great choice for a long-term relationship if you can give it great light and keep it warm; otherwise, it’s a cheap date you can flirt with all summer and try another one next year.
