Ilex 'Sparkleberry' for winter interest indoors and out

Horticulture magazine just posted an article on their website highlighting Ilex verticillata 'Sparkleberry', a lovely addition to brighten up the winter landscape or to bring branches indoors for decoration.  This prompted me to do a little more research since I am familiar with the evergreen hollies for our area but haven't delved into the deciduous varieties as much.  Since 'Sparkleberry' is a deciduous shrub, the red berries that persist through the winter really stand out adding a lovely red sparkle to the landscape.


There is disagreement as to which zone it grows best in.  I've seen it listed as growing in zones 3 - 8 but most of the listings show it as zones 5 - 9.  It is widely adaptable to varying soil conditions but since it is an Asian cross it prefers more moisture.  For best fruiting plant it in full sun and since this is a female variety, it needs to be paired with a male for pollination.  Ilex 'Apollo' has been bred to be used as the best male pollinator but other male hollies will work as well.

Sparkleberry may get up to 8 feet tall (it's listed as 12 but that is "valley speak", plants in Central Oregon never grow as big as listed on the tags) and wide and is a nice dark green turning yellow in autumn.

As with most hollies, the berries are a great food source for birds and will bring in a large variety of birds to feed on the shrub.  Another delightful addition to the landscape!

  1. Would the berries, when eaten and digested by the birds, produce Japanese or American native hollies? Is there a chance of introducing yet another invasive plant or disease this way?
