Just look at how many different palms there are in this one picture!
Mixed planting of fan palms
Our native Texas Sabal, Sabal texana, with Mediterranean Fan Palms, Chamerops humilis, in the front. The two in the middle front look to be something different but I can't tell from my picture - possibly a Windmill Palm, Trachycarpus fortunii.
Feather palms look like a feather. They have pinnate leaf which is formed by many small individual leaflets coming off the petiole. Below is an example of a feather palm. This is a Silver Date, Phoenix sylvestris. Feather palms tend to be very billowy. I think it gives them a very exotic look. The number of fronds (or branches) on this variety sure makes it look lush! Did you notice how the leaf margins have remained on the trunk? Palm people will say, "This variety keeps its boots".
Mixed planting of feather palms.
The tall ones are Foxtails, Wodyetia bifurcata and the short ones are Pygmy Date Palms, Phoenix roebelinii. New palm enthusiast almost always prefer feather palms over fan palms. But I love to mix both leaf shapes. In the combination above, the uprightness of the Chinese Fans, Livinstonia chinesis, contrasts wonderfully with the short Pygmy Dates in the front and right and mid-sized Pindo Palm, Butia capitata in the middle.
If you hear the word, inflourescence, they are referring to the bloom stem. This green one is on a Pygmy Date.
Count up the number of different palms pictured in this short post. There are hundreds of different types with wonderfully unique characteristics. I hope that you will take a closer look at the palms around you.
