Helenium autumnale is a flowering perennial plant for sun. It generally blooms in September & October. The common name is common sneezeweed & it is commonly available at most nurseries during the later part of summer. It is also called Helen's flower. The name genus name Helenium comes from the Greek word for another plant named for Helen of Troy & autumnale means 'pertaining to autumn'. Helenium autumnale is native to North America where it is widespread across the US & Canada. The only state where it has not been found to grow is New Hampshire. I'm not sure they have looked hard enough in that state. The flowers are yellow, orange, brick red, or a combination of those colors. Helenium autumnale grows to about 3 feet tall & requires a moderate amount of water. It also tolerates wetness. It is not the most beautiful of plants, but the flowers are pretty & the colors bold. It blooms at a time when there is little else.
This blog was started in 2008 as Metropolitan Gardens to provide information about gardening in Seattle & the Pacific Northwest. It was later expanded to include information about parks, community gardens & public gardens in the US, Canada, Europe & South Africa. These can be found by clicking on Parks P-Patches Public Gardens. Natural areas in the US & South Africa can be found by clicking on Nature. The primary focus has always been on Seattle. However, many posts are based on photos taken while traveling. Please feel free to use the basic gardening information & plant lists found by clicking on Gardening in Cascadia. There are also posts on Urban Landscape, which is primarily architecture. Comments are welcome. Posts are scheduled on the 1st Friday of each month October-March & twice a month April-September. If you have any questions, please contact Jordan at firstname.lastname@example.org
The city of Seattle rests between 2 bodies of water: Puget Sound & Lake Washington. Puget Sound is a substantial part of the Salish Sea & a very small part of the Pacific Ocean. The Salish Sea is set apart from the Pacific by the Olympic Peninsula in the state of Washington & Vancouver Island in the province of British Columbia. The dense, wet clouds of the Pacific Ocean travel as far as the Cascade Mountains, near the Salish Sea & not very far from the ocean. East of the Cascades lies the desert of the Columbia Basin. The moist, temperate climate of Seattle extends south to northern California & north to southeastern Alaska. The Pacific Northwest Coast from San Francisco Bay to Cook Inlet shares a flora dominated by evergreen coniferous forest. The central portion, west of the Cascade Mountains, is called Cascadia. The climate is cool & wet from fall to spring, warm & dry in summer. The Olympic Mountains block Seattle from much of the Pacific rainfall. Seattle is drier than the Atlantic coast of North America & northern Europe, cooler in summer & warmer in winter. It lies near the latitude of Paris & Quebec City.
