Asthma sufferers often complain that it is the scented garden plants that bring out the condition. Generally it is the heavily fragranced flowers but sometimes it is a single plant such as Honeysuckle.  Lilies like the Lilium Regale are one of the best scented flowers but the worst culprits for allergies.  Carnations, Sweet Williams and Pinks with a spicy scent are known to bring on hay fever.

Aromatic plants which smell due to essential oils are less likely to cause some allergies but if you are very sensitive it is best to avoid Herbs, Lavender and Eucalyptus. Or at least do not inhale bruised leaves.

Although generally unscented, many flowers from the Asteraceae or Daisy family seem to be allergenically toxic to some people. If you suffer then it is best to exclude members of this large family including Asters, Chrysanthemems, Marigolds and other similar looking flowers.

Top 5 Low Allergy Flowers

• Winter heather Erica Carnea in white and pink can look stunning from Autumn through winter.
• Geraniums such as the perennial cranesbill, Johnsons Blue is my favourite.
• Climbing roses can be a problem but Iceberg has a low level of scent and I have seen Handel and Rambling Rector also recommended.
• Fuchsia magellanica are available in many varieties
• Hydrangea macrophylla including cultivars  Ayesha, and Madame Emille Mouillere plus Lacecap varieties give you a wide choice of large flowerheads.
