Pittosporum tobira 'Glen Compact'
Also referred to as Japanese Mock Orange
We have always been very impressed with nice deep glossy green foliage of Pittosporum, but had never found a variety with a good compact growth habit, along with increased cold hardiness that we were looking for to use in more temperate climates such as East TN. Then, we found this little gem - Glen Compact Green Pittosporum!!
This pittosporum is very tightly branched, with nodes on each branch much closer together than on other pittosporum varieties. The result is a nice, dense branching habit, with super glossy green foliage. Retains a nice rounded / mound shape with minimal trimming. Has also shown increased cold hardiness when compared to most typical pittosporum varieties ( through most zone 7 locations ), especially if given some shelter from harsh winter winds. Foliage is elongated, oval shaped, and arranged in dense whorls along each branch. In spring, this shrub will produce clusters of rather small bell shaped flowers that are creamy yellow / white in color.....and very fragrant despite their small size.
Glen Compact Pittosporum makes an excellent low hedge - can also be used as a nice evergreen foreground planting, foundation planting, and looks very nice when mass planted.

7-10 will suffer some branch / foliage damage at temps below 5 degrees. ( if unsure of your zone, please use zone finder below - or check out our Hardiness Zone Map & Information Page )
Full sun to partial shade
Average to moist & fertile - well drained with plenty of organic matter is preferred. Mulching also strongly recommended for best results.
--Foliage Color & Texture:
Evergreen Broadleaf - elongated, oval shaped leaves are very dark green, and extremely glossy with a leathery sort of texture. Newest growth is a lighter green, maturing to dark green
--Flower, Cone, Or Berry Facts:
Clusters of creamy yellow / white bell shaped flowers are formed & displayed during spring. Flowers are quite fragrant. Flowers are followed by 1/4" pear shaped seed capsules if pollinated.
--Diseases / Insects:
A very tough & durable plant....with the only reported issues being an occasional bout with leaf spot or mealy bugs. But that is extremely rare.
2 - 2 1/2 feet apart for hedge type planting - widen spacing to approx 5 ft apart for foundation or foreground plantings where distinction between individual shrubs is desired.
--Deer Resistance Rating:
Lowest Resistance [ 1 - 2 -3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 ] Highest Resistance
--Fertilization / Feeding:
For maximum health & blooming, we highly recommend POOPeas for use with all of evergreen shrubs. 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.
Additional Features & Characteristics:
--Container Gardening Selection: Glen Compact Green Pittosporum makes an excellent container or patio garden choice due to its relatively small mature size, ability to be maintained at a wide variety of sizes / shapes through trimming, and a very non-aggressive root system.
