Frangipani Hardiness

Our Experience

We have spent years observing which varieties grow well in which conditions.

We stock around 5000 frangipani plants, around 500 of which are over 1 metre tall. We consider these, our tallest 10% of frangipanis in pots and bags, “our trees”.

Our frangipanis are spread around about three acres. Some get morning shade, some get afternoon shade, some have Northern protection and get little sun in winter and some are in full sun. Some get watered often and some get little more than rain.

Our Knowledge

Here are four points we consider basic but the most important.

  • All frangipanis need to get moisture from the soil to replace moisture lost through leaves but they also need soil to drain quickly.
  • All varieties of frangipanis can be damaged by the sun if moved from a shady position to full strong sun and all frangipanis build resistance each year and are less resistant to strong sun while they are small.
  • All frangipanis grow better in nutrient rich slightly acidic soil.
  • All advanced frangipani trees can handle full sun but small frangipanis prefer heat more than direct sunlight.

Our Disclaimer

Even though we have extensive knowledge about frangipanis growing on our property, we are unable to predict accurately how a frangipani will grow in distant locations or even nearby locations due to microclimate variations.

Our Definition of Hardiness

Since frost and winter climates can do the most damage to frangipanis, the ability to withstand cold weather is the most important criterion.
The second criterion is the ability to withstand adverse conditions generally be it too much or not enough water, too much or not enough nutrients or too much or not enough sunlight.

Our Frangipani Hardiness Ratings

Plumeria rubras with bright flower colours including white, light and dark pink, light orange, most yellow are the hardiest.
Plumeria pudica white is quite hardy but cannot handle weed spray at all.
Plumeria rubras with dark flowers such as red and Kimberley Sunset also grow better in hot microclimates but prefer shade more than direct sunlight until they become established.
Plumeria pudica pink do not like any adverse conditions.
Plumeria obtusa requires hot microclimates and can handle full sun.
Plumeria obtusa pink do not like any adverse conditions.
Plumeria stenophylla do not like any adverse conditions.
