Calystegia was grown in Victorian times in the United Kingdom and then discarded when it took over. It went by various names such as "spectablis" and "incarnata", the exact origin is not totally known but it could be Eurasia.

There are other forms of Calystegia which are rarely grown - such as Calystegia pulchra, Calystegia hederacea (pubescens) both the double and single form, I have species from Hokkaido in Japan.

There are noteworthy forms of Calystegia from California - such as Calystegia occidentalis, Calystegia macrostegia and a pink form of Calystegia purpurata - cultivator "Ancapa Pink" (from Ancapa Island)

...what is considered a weed to some people is a flower to others, mention morning glory to a farmer they cringe mention it to people like us here and we smile..

Here is a Victorian print of 'incarnata'

The one on ebay is Calystegia soldanella which grows on beaches etc...although it blooms in the UK it failed to do so even though it was growing through sand.

There are some interesting photos of inter-species hybrids of Calystegia here -

Here are a few hybrids I have created myself - very rewarding and covered in bloom as I speak - :)

The Calystegia native to California vary from prostrate to climbing lianes, very hardy to the UK outside if kept dry in the winter with full sun but prone to spider mite. I don't know why Calystegia occidentalis / macrostegia are not grown more often as they don't spread by the roots...and grow were very little else will.

Calystegia form hybrids amongst themselves very easily, out of interest Calystegia tugurium which has oak shaped leaves is the only calystegia to have orange coloured seed and is native to Lord Howe Island and New Zealand...
