Welsh gardens differ from English gardens more as a consequence of climate than of the Celtic design tradition. Because the country is more upland and more westerly it is wetter and windier than England. This favours the growth of rhododendrons and ericaceous plants.
Independent travellers can visit many gardens, but by no means all, using public transport. Car hire is also easy. One of the difficulties for the independent traveller is that many gardens are open only on a few days per week and only in the afternoon. This makes it difficult to visit as many gardens in a day as might appear possible from their geographical proximity. The advantage of visiting gardens with an organised tour is that many gardens are happy to open especially for groups.
