Gardeners' Notes:

Neutral Mandrew968 On Jan 14, 2011, Mandrew968 from Miami, FL wrote:

It turns out that Roystonea Violacea is indeed an actual species. The crownshaft is not purple, however. The characteristic features of this palm are violet flowers and the trunk(not crownshaft) is also violet.

Positive cfkingfish On Nov 7, 2005, cfkingfish from Venice, FL (Zone 10a) wrote:

Another fast growing member of the Roystonea genus. Coming from rural Eastern Cuba, seeds, and plants therefore, are hard to come by. There has been speculation that this species may actually be a tad cold hardier than the common regia, but this is unconfirmed. It is hard to tell the difference between this and another royals until near maturity.

Nice looking but, to me, ordinary Royal palm. As a young palm trunk has some purplish hues to dark chocolate look, but I haven't seen that myself. Flowers are violet which explains the name. From southern Cuba. Has a nice 6' long crownshaft and grows up to 50' tall. To me this one looks like a Roystonea regia. Relatively rare in cultivation, but has been doing well in some areas of southern California (not mine, though).
