Polianthes 'Pink Sapphire'

Polianthes 'Pink Sapphire' 

Polianthes tuberosa, the tuberose, must have been one of the earliest plants to be introduced to Europe from the then newly discovered Mexico. It was growing in European gardens in the seventeenth century. It's not known as a wild plant, and until very recently tuberoses came as two sorts: single and double, both with white flowers.
Now a small range of tuberoses in colors is being marketed. Here's one of them, Polianthes 'Pink Sapphire'. It seems to be a vigorous grower, but the scent is light and the pink color fades quickly to a whitish color. The real test will come in future years: will it bloom reliably?
