Gina Parkinson and her plants are beginning to wilt in the summer sun.

THE July weather has certainly sorted out the sun lovers in the garden, with many plants really suffering in the dry heat. Hydrangeas that usually do so well in our damp summers have wilted and have needed watering for the first time since they were planted, while bedding such as lobelia looks as though it won't make it to the end of the season.

Other plants, however, are thriving in the sun. Achillea and fennel are tall and strong and herbs such as rosemary, marjoram, lavender and thyme have filled their bed with aromatic leaves and blooms. The erigerons have also done well this year, enjoying the rays and the warm soil.

Erigeron or fleabane is an old-fashioned cottage garden plant that has been grown for hundreds of years. There are low-growing species and taller, border ones, but they all like the same conditions of well-drained soil and sun and will also tolerate the salty air of a seaside garden.

The dwarf fleabanes include Erigeron aureus with dense tufts of grey leaves and large golden flowers that grow up to 5cm/2ins tall and E.leiomerus with a mat of shiny foliage topped with small lavender blue flowers 8cm/3ins tall. These plants can be hard to find and in the case of E.aureus hard to grow.

Much easier is Erigeron karvinskianus, sometimes called Profusion' or Erigeron mucronatus, with masses of single white daisies from June to October. Growing 15-20cm/5-8ins high, it is easy to grow from seed and often used as a bedding plant, although I have found mine to be hardy enough to survive in the garden for several years.

The daisies fade to pink and then purple as they age, giving more interest to the plant, which usually carries blooms in each stage at once. Self seeding can be a problem, especially if grown as a rockery plant, but a position at the front of a border in competition with other plants will help to keep this to a minimum.

Taller varieties include plants in shades of pink and blue from the light pink single-flowered Charity' to the deep violet Schwarzes Meer'. I have a lilac blue variety, possibly Azure Beauty', growing with a michaelmas daisy, Aster frikartii Monch', which is almost exactly the same colour with a similar yellow centre.

This pairing is probably a mistake since they are so similar and also flower at the same time, but they do make a good clump of blooms in July and August.
