The lefthand side border is flanked by a pergola, covered with wisteria, planted by the previous owners of the house. Unfortunately these wisteria get too much food from the borders and therefore produce a copious amount of leaves, which tend to mask the flowers in June. It also has to be pruned 3 times a year – not a job for the faint hearted!

A garden develops through the years and our perennial borders are just a little bit different every year.   

We also have a few surprizes in the middle of the perennial borders, for example 

  • Poncirus trifoliatia, the only winter hard citrus tree, with small white flowers in spring and small orange fruits in October. Poncirus trifoliata also stays green throughout the winter, but beware of its thorns.
  • There are also 3 eye-catching hydrangeas, 
    • Hydrangea macrophylla Zorro
      Hydrangea macrophylla “Zorro”Blauw

      Hydrangea macrophylla “Zorro” Blauw, with jet black stems and blue flowers, 

    • Hydrangea macrophylla “Zorro” Rose , also with jet black stems but pink flowers and
    • Hydrangea aspera “Hot Chocolate”, a unique hydrangea with red-brown velvety leaves and lovely purple-pink flowers in summer.
