Thuja koraiensis 'Glauca Prostrata'
A truly interesting form of Korean Arborvitae - virtually impossible to find in the landscape / nursery industry. As the name would indicate ( Prostrata ), this is a fairly low growing plant with a somewhat prostrate growth habit when compared to many arborvitae. It's spreading, globose growth habit, makes it a good choice for foreground plantings as well as lower accent or group plantings. Foliage color is a very attractive silvery blue color - one of the only Thuja varieties with this foliage color!! Really have to see this plant in person to appreciate the unique coloration of the foliage.
This is also one of the few Thuja varieties that we have seen thrive very well in fairly semi shaded areas - although foliage color is best in planting locations with good sun exposure ( 5-6 hrs full sun per day ).

Diseases / Insects: The usual occasional bagworm, or spider mite infestation is possible - as with most all Thuja varieties. Appears to be very resistant to most other pests / problems though.
Fertilization / Feeding: For maximum health & color, we highly recommend POOPeas Organic Fertilizer & Soil Conditioner.
However, either water soluble ( Miracle Gro, or equivalent ), or
granular fertilizers ( Holly Tone is excellent ) are also good options. Most any granular fertilizers with a 6-12-12, or
10-10-10 ratio are also acceptable. Best to fertilize in early spring,
and again in mid fall - avoid feeding standard chemical fertilizers
during hot summer months, and directly after transplanting. POOPeas may be used at anytime.Recommended Spacing: 3 ft apart recommended for hedge / mass plantings
Deer Resistance Rating: 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 [ 1 - least resistant........10 highly resistant ]
