Hi all. I was talking to my mum today about the house we lived in when I was little. She mentioned the garden had loads of 'rose of Sharon' in it. I have scoured to tinterweb and decided I really really want some. Been to 4 nurseries today and they don't stock it and are unlikely to order in specially for me. Any ideas where I can get some? It looks so nice and will sit well in my tropical themed garden

It's hypericum, there are several varieties, and some can be quite invasive, but I am no expert on which ones.

One of my first ever gardening tasks was helping my mum clear a larged terraced area of garden of Rose of Sharon - it nearly put me off for life! 

Ours was a spreading, low-growing type (Hypericum calycinum, I believe, and it is definitely quite invasive!) - other types form quite large shrubs with very attractive flowers, and are probably the ones you are thinking about.

There are a few UK suppliers listed on line if you are happy to buy that way.

This is one although I have no info one way or the other about whether they are a reliable supplier or not.

more than one plant with the name, according to wiki:

Hypericum calycinum, an evergreen flowering shrub native to southeast Europe and southwest Asia, and the plant generally referred to in British and Australian English as "Rose of Sharon"; and
Hibiscus syriacus, a deciduous flowering shrub native to east Asia, the plant generally referred to in American English as "Rose of Sharon"

I'm not keen on the first type, because they look very straggly and poor after a while - think railway embankments  But the second type are very pretty

I really don't remember it in our garden but my mum says it was low growing. Took some pruning but looks lovely when in flower.

what colour were the flowers?  that will easily tell which it was 

Yellow flowers and it's hypericum pink or white and it's Hibiscus

[Rich72]

Definitely yellow flowers
