Although not mentioned in any of my three Loire Valley guide books, this excellent 'Jardin Botanique' is well worth visiting. The animals housed within the gardens will even keep the children interested.
Unfortunately, the glasshouses at the Northern end of the gardens were closed at the time of my visit.

Zurich Botanic Garden Poncirus group
There is a lovely group of Poncirus trifoliata plants either side of the path through the south-facing, dry rock garden. All carried fruit when photographed in  August 2005.
This winter photo of an old, single-stemmed specimen was sent to me by Frédéric Tournay, curator of the gardens.
Taken January, 2009, a few remaining fruits are just visible.

There are two specimens in the gardens. This is the better one, in the small lake-side area reached by a passage under the road from the main garden. Multi-stemmed and plenty of fruit in November 2005.
