I found another exotic mysterious plant in my pond – yes, in the pond and we have been here four years. I realised that since the water has almost dried out this spring, it has given the Jacobean or Aztec lily a chance to grow and flower.

Searching on the internet and asking friends about the beautiful red flower, I found this website with the information – mystery solved. Below is what they said:

As there is no need to say much about this beautiful lily apart from the fact that we have found them extremely easy to grow. Jacobean lilies grow very well in full sun.
In Queensland, they tend to flower at all times of the year (in fact, there is very rarely a month without some flowering somewhere in the garden).
Jacobean lilies do less well under trees but do survive and multiply and lastly they prefer to be in soil that drains freely.
The Aztec lily is an absolute joy to have in the garden or in pots and are very companionable with other plants.

After the flowering, I have transferred the Jacobean lily to a nice dry sunny spot, hoping for more gorgeous flowers in the future.
