Information about Polianthes tuberosum

This question was asked by
Andrew B

Please can you advise me if these bulbs are easy to repeat flower in successive seasons or should they be regarded as annuals?
I had some several years ago but could get them to flower in the second year!
Thank you for your help.

Hi there,

Yes your Polianthes Tuberosa should come back each year like most bulbs. They just need a little care over winter.
Move your containers to a frost free location before the first frosts.
If your bulbs are planted in your borders, they need lifting before the first frosts and stored in a frost-free location.

Polianthes Tuberosa in pots

This question was asked by
Jackie M

Hello Harts. I bought 3 Polianthes Tuberosa to grow in pots. They are currently in 10cm sqare pots in a heated propagator. Can you please advise me what size pot they should ultimately be potted up into, either together or singly.
Many thanks,

HI there,

I would advise planting one polianthes tuberosa into a 10-12cm diameter pot or three tubers into a larger 15-18cm pot.

I am widowed and retired, a gardener not……Are there perennials that will appear throughout the year.

All our bulbs are perennials and they will come back each year. Depending on which bulbs you plant will depend on what time of year they will flower. Our website will tell you when each bulb’s flowering period is.


Start by looking in the Spring Planted Bulbs and Lilies Categories – these will flower this summer. Then you will need to look at the Autumn Planted Bulbs and these will flower int the Spring.

Growing tree Lilies in limestone

This question was asked by

Do you have Tree Lilies that will thrive on Portland Dorset, we are limestone based really.

Tree lilies are happy in any well-drained soil type. Alternatively, they can be planted in pots.

We have lots of tree lilies here:
