Summer Flower Shapes and Forms

Summer Flowers: Shape and Form

Summer is the time when the lovely and varied forms or shapes of the flower heads provide interest in their full bloom.   Grouping similar flower shapes together and contrasting them with different forms is a significant part of good planting design for herbaceous planting. The many choices of flower shape include include daisies, spires, umbels, buttons and globes. To keep flowering as long as possible, ‘dead-head’ the fading flowers to give the chance for many new flowers to bud and bloom and as the summer recedes leave the seedheads to preserve the flower shape well into winter.

Daisy Flowers:

 Orange Echinacea 'Arts Pride' with blue Echinops ritro.

Orange Echinacea ‘Art’s Pride’ with blue Echinops ritro.

Coneflowers – Echinacea have a daisy flower shape and are in flower from mid-summer through to October in a sheltered south facing spot. They have gorgeous cone shaped florets in the centre shown here in the orange ‘Arts Pride’. In the background, a round blue globe flower shape of Echinops ritro provides contrast of both colour and form.



Helenium 'Moerheim Beauty'

Helenium ‘Moerheim Beauty’

Heleniums – or ‘Helen’s flowers’ – are another daisy form with similarly interesting bulbous florets. This one is ‘Moerheim Beauty’. It grows tall – more than 1 metre and needs sun and water to keep it upright.




Anthemis tinctoria 'E.C. Buxton'

Anthemis tinctoria ‘E.C. Buxton’

Camomiles – A great small daisy is Anthemis tinctoria E.C. Buxton.  It grows to about 50 cm with loads of yellow flowers and sparkles in pots or borders.  It too needs lots of sun.  Cut the flowers for flower arrangements with salvias and other summer perennials.




Flower Spires:

Agastache 'Blackadder' in front of pink Rosa 'American Pillar'

Agastache ‘Blackadder’

Agastache or Hyssop – ‘Agasta’ means ‘with great charm’ – and these smoky violet spire flower shapes of Agastache ‘Blackadder’ are particularly charming with the pink American Pillar rose behind it. 

It grows more than a metre tall and its spires grow like bottlebrushes crammed with tiny flowers and needs sun and shelter.  Many salvias have similar slimmer spires in blues, lilac, lavender and pinks and enjoy the same conditions

Flower Umbels:

Achillea 'Walther Funcke'

Achillea ‘Walther Funcke’

Achillea or Yarrow has lovely flat umbel or umbrella  flower shaped heads in reds, oranges, yellows, pinks and whites.  The plant is named after the greek warrior Achilles who stopped the flow of blood from his soldiers wounds with a concoction made from yarrow.  This one is ‘Walther Funcke’ and is rather funky with its changing colours of terracotta to ochre.

Other umbels include phlox, angelica and sedum and they all provide good contrast with upright spires of other plants

Button and Globe Flowers:

Astrantia 'Roma'

Pink pincushions of Astrantia ‘Roma’

As well as the blue globe thistles, maroon Knautia macedonica, and the palest pink to rich maroon Astrantias have the small tightly packed clusters of flowers that make a button or globe flower shape. Astrantias need a cooler spot with partial shade and combine well with Alchemilla mollis or ‘Lady’s Mantle’.  



All these flowers are attractive to bees and butterflies and by choosing different flower shapes and hence different species, a wider range of butterflies will enjoy your garden too.
