By Billy Aiken

 

Why jet off to foreign places when you can escape to a tropical location this summer by bravely walking into your garden. There are a huge number of incredibly luscious tropical plants that can be easily grown in Auckland.

 

Hover over the interactive image below for details of how you can create this look in your own garden.

 

Here are 10 of our favourite tropical treasures:

 

Hibiscus

 

 

Whether it’s deciduous or evergreen, large or small, any hibiscus in flower will undoubtedly catch your eye with its gloriously stunning display.

There are loads of different varieties of tropical hibiscus, but they all fall into three main types, and knowing a bit about each will help when you make your choice.

 

Fijian

Cold-hardy shrubs that normally retain their leaves through winter. The flowers are slightly smaller than the other types of hibiscus and the shrubs tend to be relatively large.

 

Hawaiian 

Smaller-growing, cold-tender shrubs with huge flowers.
Like to be grown in a warm, sheltered, sunny site. 

 

Clarke's Hybrid

New Zealand-bred varieties by Jack Clarke that are ideally suited to Auckland conditions. They are a cross between Fijian and Hawaiian hibiscus.

Growing Tips

These plants have fairly delicate roots, and they hate to sit in wet soil. To avoid problems:

  • Leave in the original container for a year, though you can place it where you would eventually like it.
  • When you do plant it out, either plant into a container or in spot that is very free-draining.
  • Over summer frangipani like the soil to be kept moist but not damp. In winter they require practically no watering. If in a container, many people will bring them inside over the winter to help protect them.
  • Make sure that it is kept in a frost-free place over winter.
  • Feed every 4-6 weeks through spring and summer with half-strength mix of Kings Ocean Grow to keep them well fed and healthy.

Growing Tips

 

Position

Part shade-shade. Plant in free-draining soil rich in organic matter.

Planting

Mix in compost before planting. Or in poor-draining areas use Living Earth Garden Mix to create a raised bed.

Care

Feed with Kings Ocean Grow.

 

Mandevilla

 

AKA Rocket Trumpets

Although their common name in the USA sounds like they’re a 70s jazz fusion band with pretensions, Mandevillas are actually a genus of delightful sub-tropical and tropical vines. Vines that in New Zealand regularly erupt each summer with vibrant eye-catching flowers in a variety of colours, including whites, pinks and reds.

 

 

Growing Tips

Position

Best planted in bright, indirect light. They can get burned if they get too much direct sunlight. 

Soil

Prefer free-draining soil rich in organic matter.

Care

As Mandevillas are vines they will need some support, use trellis or some other form of support for them to grow up.

Water and feed regularly.

Gardenia

 

 

Producing an abundance of exquisitely scented blooms, these delightful tropical plants are well suited to Auckland's climate. There are many different cultivars available, from groundcovers to small shrubs. Most produce pure white blooms, though a few yellow flowering varieties are often available.

 

 

Growing Tips

Position

Best grown in part shade. Gardenias require bright light to flourish and can often deal with full sun. However, they may get sunburnt over summer if they aren't in some shade from the midday sun. 

Prefer free-draining, slightly acidic soils rich in organic matter. Add compost and sheep pellets to the soil before planting and avoid using lime. To help soil structure in heavier soils use Gypsum as it won't effect the acidity of the soil.

Care

Water regularly through summer and keep the soil moist but not damp.

Feed with Kings Slow Release Acidic Fertiliser or, for a natural option, use Aquaticus Organic Garden Booster.

If the leaves of  your gardenia start getting yellow apply Sequestron or Epsom salts

 

Vireya

 

 

Before flowering, tropical vireya rhododendrons don’t particularly catch the eye, despite their relatively attractive, dark green foliage. But as soon as their flower buds burst they become truly stunning, as they provide a bright and incredibly opulent display that is staggering to behold.

Smaller than other rhododendron, most vireyas grow around 1-1.8m.

 

Growing Tips

Position

Vireyas prefer dappled shade, though they will cope with anything from moderate sun to fairly dense shade.

Prefer free-draining, slightly acidic soils.
