Ilex x attenuata aurea and Ilex vomitoria...two lovely native hollies















Strictly speaking the gold fruited selection is a hybrid between two native hollies, Ilex cassine and Ilex opaca. The red berries belong to Ilex vomitoria, or Yaupon. Yaupon is a southern holly as is Ilex cassine. Neither is widely distributed this far north, but both are hardy here. As climate changes bring warmer winters farther north, these two SE taxa may be reasonable choices as far north as coastal New England.

Ilex macrocarpa...I bet you've never seen this plant before!

Hey, I know I never have. Its an Asian deciduous holly, and though the scale isn't obvious from the the picture, the fruits are large, right around a half inch in diameter. One of the nice things about working at the National Arboretum is the regular opportunities I am afforded to see plants I have never seen before. I guess its a bit embarrassing to admit that I have been driving past this particular plant for the last 4 years without noticing it, but in my own defense, it is a bit nondescript until the fruit appear and this is the first year it has fruited. I would love to add information about it but, while it is not ungoogleable (bad word, sorry), I found nothing other than the fact that it is on some lists and planted in a few other gardens. Well, it seems happy in an exposed position in the warm part of USDA Zone 7 and it has cool fruit~
