Planting on thin Chalk Soils

Planting thieving on poor soils.

For most gardeners, the soil is the thing that gets us all most worked up, and thin chalky soil for most would seem a real challenge and perhaps a hurdle to far; but do not despair, because in fact there is a huge variety of plants that love thin poor well draining chalky soils. Think of all the billowing scents and colours of the southern Mediterranean and you already have a plant palette to build on. Here are just a few to whet your appetite.

 Thymus vulgaris 'Sliver Posie'

Thymus vulgaris ‘Sliver Posie’

Thymus vulgaris ‘Sliver Posie’: this is one of my favourite thymes, it grows to  about 15cm high and produces a compact habit. With soft evergreen silvery leaves with cream variegation and light mauve flowers in the mid summer. It will do well in a sun baked spot.

 Iris 'Brathwaite'

Iris ‘Brathwaite’

Iris ‘Braithwaite’: Breaded Irises do very well on poor soils with good sharp drainage. This tall variety up to 75cm, wants full sun. it has grey leaves and stunning flowers with regal purple velvet uppers and soft mauve falls and an orange throat, flowers produced in May. It will flower well, where its rhizomes can be baked.

 Lavendula angustifolia 'Munstead'

Lavendula angustifolia ‘Munstead’

Lavendulea angustifolia ‘Munstaed’: This small compact variety has all the traditional traits of the common ‘English lavender’ but without the size, so is more suitable for a small garden growing to 40/50cm tall. With good evergreen aromatic sliver foliage and the light mauve of traditional lavender flowers produced freely in midsummer.

Salvia officinalis 'Purpurascens'

Salvia officinalis ‘Purpurascens’

Salvia offcinalis ‘Purpurascens’: Herbs are not just for the herb garden of the cooking pot and this is one of them. This beautiful evergreen purple sage, makes a good low growing ground cover plant, with soft grey/purple foliage and spikes of  small purple flowers in the summer, it likes a good sunny spot.

 Helianthemum nummularium 'Wisley Primrose'

Helianthemum nummularium ‘Wisley Primrose’

Helianthemum ‘Wisley Primrose’: is one of the best ‘rock roses’ there is, it thrives in dry poor spots  in full sun and it will happily grow on the tops of walls or the edge of dry Rockies. Reaching the dizzying height of about 10cm, with soft evergreen sliver foliage  and a succession of  round open clear yellow flowers from midsummer onwards.

Ulex europaeus 'Flore Pleno'

Ulex europaeus ‘Flore Pleno’

Ulex europaeus ‘Flore Pleno’:  There is nothing quite as tough as old boots, than gorse, it will grow on the very poorest and thinnest of soils and in the south of England has an unbelievably long flowering time, starting from late February through to midsummer and even a flush in the autumn. This variety has a compact habit with dense spiky evergreen foliage and  brilliant yellow pea like flowers, which bees love.

I hope I have inspired you to think more positively about your chalky poor garden soil and realise that there is a large variety of plants that can be grown and even thrive  on your garden soil type. All of the plants I have chosen happen to be sun worshippers but there are also shade lovers that will do well.
