Blue Fleabane __EXCLUSIVE__
Erigeron acer is a widespread herbaceous flowering plant in the family Asteraceae. Common names include bitter fleabane and blue fleabane. The species is native to Canada, colder parts of the United States, northern, central, and southeastern Asia, and most of Europe.
Befitting a love of well-draining, often quite desolate conditions, I have encountered this species at three sites locally of late. At the first of these, multiple plants were found growing in long-abandoned planters in my local industrial estate, notably in close proximity to Fern-grass (Catapodium rigidum) and other colonisers typical of such habitats. My second encounter came at Walker Riverside where several plants were found growing in pavement cracks by the Tyne. Finally, two more clumps of fleabane were spotted at Newburn Industrial Estate this morning.
Blue Fleabane is similar in appearance to other small-flowered fleabanes in sporting small, inconspicuous flowers borne in panicles. The individual flowers appear flat-topped with ray florets only slightly longer than the disk florets. These lilac outer rays emerge from a yellow centre and from a distance, making the flower appear somewhat blue in colour. It is this feature which gives it the name, Blue Fleabane.
Canadian Fleabane (Erigeron canadensis) is a common non-native plant across much of the UK, including in the North East. This species tends to be far larger (but not always) and usually sports much more numerous flowers than Blue Fleabane. These are usually smaller too and lack attractive blue colouration.
Erigeron (Erigeron Speciosus Macranthus) - Erigeron Macranthus, also known as Aspen Fleabane, grows to approximately 28 inches tall with clear blue flowers and a slightly yellow center. Use Erigeron in the front of flower gardens, rock gardens, and containers. It is great for cutting, and it will attract lots of attention from butterflies. Erigeron is easy to grow from flower seeds, and once it is established, it is versatile and hardy. Avoid excessive watering. This flower needs a few days between one watering and the other. Watering deeply with a bucket of water every two to three weeks is plenty of water for this plant. Deadhead plants to extend blooming period. 041b061a72
