Comment |
Erect Form. Pruning Group 14. "Helenium 'Indianersommer' ('Indian Summer') is a medium-sized perennial producing striking brick orange red flowers with dark brown centres all through summer. It works very well in a hot-themed border, and is an ideal choice for attracting butterflies and bees into the garden. Plant in full sun, in a moist but preferably well drained soil. Height to 70cm. For the purposes of definition, late summer flowering perennials may be described as plants that reliably produce flowers or that have as their main feature of interest (an architectural silhouette, or attractive seed heads for instance) which can positively contribute to the garden after midsummer's day on a year in year out basis. There is little doubt that the climate is changing,for whatever reason, and that seasons are not as distinct. In Britain the autumn season is lengthening and often there is relatively frost free weather up until December. The majority of gardens in Britain look at their finest in the spring and early summer, leaving many gardens looking relatively lacklustre after June has passed. The use of these late summer flowering perennials in the garden should renew inspiration in the months of the year when the shadows are lengthening." from Plants to Plant. Available from Crocus and Sampford Shrubs in the UK. |
