Christmas Palm tree is magnificent, adding a luxurious, vacay vibe to any brightly lit room.This adorable palm looks like a miniature of the Royal Palm -- the stately giants you see lining boulevards in South Florida and California.It grows from a single trunk, which supports a crown of arched, pinnate leaves. At the base of the crown, clusters of creamy white flowers emerge. In fall, these flowers are replaced with 1 in (2.5 cm) green fruits that ripen to bright red around the end of December. They look like red Christmas lights, giving this stunning tree its common name.This Southeastern Asia native is surprisingly tolerant of growing in a pot and will thrive indoors as long as it gets plenty of sunshine throughout the year.You can move this palm outdoors to the patio for the summer, but bring it back inside if the temperature drops near 40°F. This tropical palm doesn't like the cold at all.
