Cold Hardy Heliconias and Gingers
Heliconias and Gingers for Sydney, Coastal NSW and a few for Melbourne
In this article you will find information on Growing Cold Hardy Heliconias and Gingers
Picture a lush tropical garden and I bet the image you conjure up will include heliconias and gingers. In coastal Queensland, they are easy to grow if you can keep the water up and have a good microclimate. Some areas like parts of Brisbane can be a challenge and we have written an article for Brisbane and novice Queensland Heliconia growers here. In this article, we are covering more challenging areas. Growing heliconias and gingers in Sydney and Melbourne and cooler coastal areas in between.
Ones of the most important things to understand is that there are other factors that will influence your success rate besides temperature and water. Microclimate is the mini climate created in an area that can increase humidity, protect from wind/frost and increase temperature. Urban Island Heat is another concept that allows some tropical to grow better in cities because of the microclimate buildings create. Amending your soil so it is light fluffy and has lots of organic matter is extremely important in cool climate tropical gardens. Winter rain can also be problematic in cooler climates as most tropical become dormant in cooler temperatures and their roots will rot if drainage is insufficient. Excellent drainage is a MUST for heliconias and gingers in Sydney and Melbourne. You’ll find more information on these concepts here.
Heliconias and Gingers will need more protection from the sun and wind in cooler climates. That means you will need morning sun, part shade or a canopy. Heliconias and Gingers will most likely look scrappy in full sun in your climate.
Now armed with a reasonable amount of knowledge you can get into the meat and potatoes of the subject. Which of the heliconias and gingers here will grow best in cooler climates?
First off, I need to say unless you are growing in a hothouse STAY AWAY FROM TORCH GINGERS ANYWHERE BELOW BRISBANE. Yes, they are gorgeous and I know you want them but they’ll be dead long before they flower. They have no cold hardiness.
The good news is, in Sydney and on the Central Coast of New South Wales there are a surprising number of heliconias and gingers that will grow well.
