I love the size of these indoor/outdoor topiaries.  I plan to put mine in planter urns outside and then do plantings of annuals and tulip bulbs around them.  For winter, these will add some evergreen elements to my garden but at the same time save me from having to trim, worry, shear or fuss with live plants.  I'll also add some stems of greenery like pine and juniper for winter interest.  The balls are big enough to be seen and make a statement yet the price is reasonable.
They do look fake on closeup but I believe when other flowers and plants are put with them they'll look much more realistic.  They have been outside 24/7 for almost a year and the greenery has maintained it's colour and has not faded.  I highly recommend these and I would absolutely buy them again.
