Cedrus libani 'Katere' is a dwarf, spreading selection of Cedar of Lebanon with attractive medium-long blue-green needles and layered branching. Older plants will often look ancient and weathered, a natural Bonsai in the garden. After 10 years of growth, a mature specimen will measure 12 inches (30 cm tall and 18 inches (45 cm) wide, an annual growth rate of 1 to 2 inches (2.5 - 5 cm).
This cultivar originated as a seedling selected in the early 2000s by Cedar Lodge Nursery, New Plymouth, New Zealand. 'Katere' is one of seven selections made in 2019 for the popular ACS Collectors' Conifer of the Year Program.

Can the cedar of lebanon handle zone 6 and there seems to be some discrepancy over the mature size of this plant.
yes, this species should be hardy to Zone 6 and has evolved to thrive in a Mediterranean climate. Since it has only been around for 20 years, there's probably not enough data to establish a mature size. Conifers typically take 50 years to reach reasonable maturity. Remember, they never actually stop growing.
