Tender Perennials in the Garden


AMONGST THE LOVELIEST and most desirable of summer flowers are those which will not withstand frost. Less-hardy plants make excellent subjects for pots and containers. Grouped together on a terrace or beside a door they can form an attractive feature.

Lobelia syphilitica – These elegant blue spires would enhance most situations. Soil should be kept moist. 1.2m x 30cm/4 x 1ft

Lobelia tupa – Spectacular in flower, this lobelia requires really good drainage and protection from winter wet. 1.2m x 30cm/1 x 1ft

Gladiolus hybrid – Possibly these tall, rather stiff flower spikes are at their best in a formal bedding scheme. 1.2m x 30cm/4 x 1ft

Salvia discolor -Absolutely outstanding. Indigo-black flowers above white-felled leaves. Keep frost free. 60 x 30cm/2 x 1 ft


Many of these tender perennials will survive the winter provided they are given a frost-free place.

Grow them in pots throughout the colder months and then transfer to the open ground for the gardening season. Repot as the temperature falls.

Gazania South African daisies, available in a whole range of colours, make for an intense show. 30x20cm/1ft x 8in

Lobelia cardinalis ‘Queen Victoria’ – Deep wine red leaves and stems and intense red flowers dominate this striking plant. 90 x 30cm/3 x 1ft ♦ Surprisingly this foliage and flower looks superb when set against orange.



A LATE SHOW – As SUMMER DRAWS TO A CLOSE the autumn flowers come into their own.

Exciting kniphofias, fiery crocosmias and late-flowering salvias ensure an interesting and continuous display.

Crocosmia ‘Lucifer’, Dahlia ‘Bishop of Llandaff’ – Placed together these two late flowering plants bring excitement to the border.

Kniphofia caulescens – This striking poker has interesting grey-green, serrated leaves. 1m x 60cm/3 x 2ft

Dahlia ‘Grenadier’- Tuberous dahlias dress up an end of season border. 60 x 60cm/2 x 2ft.


GLOWING COLOURS typify the time of year. A last rose (’Just Joey’), the flat yellow heads of achillea and generous clumps of crocosmias and dahlias maintain interest throughout the garden. For added interest, you could add in the foreground the crimson tassels of amaranthus (Love-lies-bleeding) which would elegantly sweep to the ground.

Macleaya microcarpa – Allow plenty of space for iliis dramatic perennial. 2 x 1m/6x 3ft.

Fuchsia magellanica ‘Gracilis Variegata’ – A graceful shrub with slender crimson-purple flowers. 75 x 75cm/2½ft x 2½ft

Anemone hybrida – Japanese anemones have a long flowering period. 1.5m/5ft.

Liriope muscari – Tiny spikes of violet flowers are sometimes masked by the leaves. 30 x 45cm/1 x 1½ft

Crinum powellii – These beautiful, fragrant flowers are effective against a sunny wall. 1m x 60cm/3 x 2ft. ♦ Crinums are not difficult to grow but they do like a rich, well drained soil.

Crocosmia ‘Mount Usher’ – No garden should be without a selection of these perennials. 60 x 30cm/ 2 x 1ft.

Kirengeshoma palmata – A plant for moist ground close to water. 1m x 75cm/3 x 2½ft

Agapanthus ‘Loch Hope’ – Amongst the most magnificent of dark blue forms of African lily. 1.2m x 75cm/4 x 2½ft

Aconitum carmichaelii – Roots of Monkshood, or Wolf’s bane, are poisonous. 1.5m x 30cm/5 x 1ft
