Catalogues and guides list the plant size at maturity, which is critical for proper spacing on your plan and in your yard. You should also know the time of year when the flower or shrub is in bloom, especially if you're trying to maintain color throughout the entire growing season. You need to decide what sizes to buy your shrubs and trees at. They're sold at several stages of growth in 1 to 7-gallon containers. But you can get larger ones balled and burlapped.
Small plants are cheaper but they take longer to reach maturity.
So it's really a question of budget versus patience. You can read a short description of the tape and find out how to order it by linking here to its section in the Hometime Store .
