Comment |
Erect Form. Pruning Group 14. "(September Ruby) Large, rich purple-red flowerheads from September into October. Very similar to ‘Lou Williams’ but a much weaker plant. 130 cm. Please note orders will not be sent out until May 2013." from Old Court Nurseries & The Picton Garden. "Also known as Fall Asters, these are terrific favorites for autumn colour in the perennial border. Plants form a bushy clump, bearing loads of small daisy flowers. This is a tall-growing selection with deep ruby-red blooms. Pinch plants before July to reduce height, or plan to give support with stakes. Excellent for cutting. Most asters will be troubled much less with powdery mildew when grown in a moist, rich soil. Divide plants every two to four years to maintain vigour." from Heritage Perennials. "You´ll almost look forward to autumn to see this splendid variety in bloom! A very vigorous plant, it bears in September and October an abundance of ruby-coloured flowers. Needless to say, flower arrangers won´t be able to wait to get their hands on them! 4 ft." from Chiltern Seeds . Available from Shoot and Old Court Nurseries & The Picton Garden in the UK with seeds from Chiltern Seeds and B & T World Seeds. |
