Autumn flowering pansies are in store now, ideal for replacing summer bedding as it starts to run out of steam. Plant Pansies in a sunny spot in well drained soil. Don’t let them dry out and they should flower well into late Autumn and if they dont get frozen solid they should flower again in Spring. Deadhead them to prolong flowering. Violas have smaller flowers than their pansy relatives but some of the are scented.

Dwarf Miracle cyclamen are becoming increasingly popular as Autumn bedding. They can flower for months and in mild weather they can last in flower till near Christmas. They will take a bit of cold, but it is best to cover them with fleece in cold weather or bring containers in. Keep them moist but not too wet and avoid watering the flowers if you can. They look great in pots and window boxes.

We usually have Special offers on Cyclamen in early Sepember.

7. Pot Mums

Masses of daisy flowers in many colours, flowering from late August to November or even December. Ideal for containers, pots and window boxes for late season colour

The smaller flowered 'Rostrevor' is hardier than the more spectular 'x Nymansay. Glendoick offer a compact free flowering form called 'George Graham' which is an excellent plant. You can see a fine 'Rostrevor' in our display garden at Glendoick.
