Our perennials will be 6 to 9 months old. Our shrubs will be 12 to 18 months old. The plants will be fully rooted and leafed out. The plant tops will vary in height by variety, but if they are taller than 6-8" above the pot we may have to cut them back to fit in our boxes. This does not harm the plant in any way, and actually helps to promote a bushier, fuller plant.
