This is a hardy shrub in a genus that is known for being decidedly tender. A fantastic black leaved evergreen shrub from New Zealand which is an exciting hybrid. Small, glossy green leaves stained with black on handsomely patterned branches. Full sun to light shade. Spreading habit is low when young eventually it grows upright to 4′ tall and 5′ wide with a distinctive and beautiful tiered branching pattern. Insignificant small white flowers- they look like little translucent white worms- way more unobtrusive than it sounds. This shrub has shocked us with its hardiness to cold. It survived temperatures in the single digits in a container and didn’t flinch. This is a wonderful foliage shrub that should be more popular. Excellent appearance year round. Drought tolerant. ‘Black Cloud’ Mirror Plant. Use as a small scale ground cover or first rate landscape plant. Very easy to grow.
Famous for its hardiness to cold, this shrub eventually becomes very big with very large double, powerfully fragrant flowers. This fabulous Gardenia gains cold hardiness with age. Rich, moisture retentive soil that drains- see- LOTS OF COMPOST and regular summer water. That will not only speed growth an establishment it will encourage a constant supply of blooms from on average early July to September. To 4′ x 6′ in 7 years. Best in a protected location- especially from east winds. Full sun to full shade. Excellent with some overhead protection- tree branches , eaves, or a pergola. This slight protection provides the plant with less dramatic swings in temperatures which helps it harden off to cold. REGULAR irrigation is crucial for the first few years. Never let a Gardenia dry out entirely- no like. All the leaves from the interior out will turn yellow and drop. Not pretty. But a well grown shrub is gorgeous with large, deep green glossy foliage ensconcing the 3″ wide flowers. The fragrance will waft in warm summer conditions. Lovely. Excellent in containers – pay attention to irrigation and move the containerized Gardenia to an unheated garage or porch. Lucious and very tropical looking.
What was once a separate species has been lumped into the general name for this popular shrub. We’ve grown many “hardy” gardenias and many failed but this one is a bona fide success. Easy to grow shrub that blooms and thrives with correct care and its perfectly hardy to cold. To 3′ x 3′ in 5 years in rich, well drained, moisture retentive soil. Fully double 3″ wide powerfully fragrant sweetly scented flowers appear in PDX from July to October. Slow but steady growing shrub. Never let newly installed plants dry out completely. Once established it requires the same water and care as a Kerume Azalea. Add a handful of organic fertilizer or cottonseed meal in early June prior to flowering. Perfectly hardy to cold in our climate and has naturally low heat requirements to bloom. Handsome evergreen shrub. We recommend ‘Frostproof’ for part shade as its flowers will last longer when not fried by hot sun.
