|I am trying to find a columnar bush or small tree that would not grow wide than 3-4'. This would be in the front of a one story house so I don't want something extremely tall growing. Preferably an evergreen of some sort. Thank you.|
Those space dimensions make for a short list of plants. Here are some possibilities and comments.
Nandina - standard types reach to about 6 feet tall. However they can spread slowly so you will need to dig sucker plants on occasion.
Dwarf Burford Holly - Slow grower to 4 to 6 feet tall and wide. Can be kept to about 4 feet wide with prunining.
Wichita Blue Juniper - Moderate grower to 10 to 15 feet tall, 4 to 6 feet wide. Larger with age so you would probably need to remove it down the line.
Weeping Yaupon - These have an upright trunk and then arching/weeping branches.
One of the many topiary types of juniper sold by Monrovia. These are some work to maintain the nice shape and form, but are very attractive.
Thanks for the question. Please stop in again soon!
