My Slowest Growing Shrubs

Now that I've been gardening in my present location for almost twelve years, I thought I should take an inventory of my slowest growing shrubs:

Osmanthus heterophyllus 'Ogon' is probably my slowest growing shrub.  It is now over ten years old and about one foot tall by two feet wide.

Chamaecyparis obtusa 'Torulosa' is now eleven years old, and is about four feet tall.

Camellia truncata is now seven years old and about a foot and a half tall.  It reliably produces nice white flowers every winter.

Illicium henryi is nine years old and about three and a half feet tall.  It's related to the shrub that produces the spice star anise.

For the first time this year, my Illicium henryi has produced a seed pod.
