Oxeye Daisy (Chrysanthemum leucanthemum syn. Leucanthemum vulgare) Provincial Designation: Noxious Overview: Identification: Introduced from Europe in the early 1800’s Stems: Multiple, un-branched stems grow up primarily as a grass seed contaminant, and to 1 m tall and are smooth, frequently grooved subsequently spread as an ornamental, and generally hairless. Oxeye daisy has become a serious invader Leaves: Basal and lower leaves are lance- of pastures and natural areas throughout shaped with “toothed” margins and petioles North America.

The population 12 and range declines of a suite of North American bumblebees, a group of important pollinators, 13 have been linked to emergent infection with the microsporidian Nosema bombi.

We investigated whether a root-feeding moth found closely associated with oxeye daisy in Europe could be used as a biological control agent for the plant when weedy. We found that the moth could develop on 11 out of 74 plant species that we tested in laboratory conditions when it was given no choice of plants. When the Citation: Stutz, S.; De Clerck-Floate, moths were given a choice of food plants outdoors, we found its larvae only on the ornamentals R.; Hinz, H.L.; McClay, A.; Shasta daisy and creeping daisy.

Florian Wagner iv Abstract Plant systematics, the study of taxonomy, phylogeny and evolutionary processes in plants has undergone considerable progress in the last decades. The application of modern molecular approaches and DNA-sequencing techniques in the field has led to an improved inventory of biodiversity and a better understanding of evolutionary processes shaping the biological diversity on our planet. The increased availability of molecular and genomic data has particularly facilitated the investigation of shallowly diverged and taxonomically complex taxon-groups, which is challenging due to minor morphological differences, low genetic differentiation and/or hybridization among taxa. The present thesis investigates species delimitation, hybridization and polyploidization in the recently diverged genera Leucanthemum Mill. and Rhodanthemum B.H.

Plant Species to AVOID for Landscaping, Revegetation, and Restoration Colorado Native Plant Society Revised by the Horticulture and Restoration Committee, May, 2002
Plant Species to AVOID for Landscaping, Revegetation, and Restoration Colorado Native Plant Society Revised by the Horticulture and Restoration Committee, May, 2002 The plants listed below are invasive exotic species which threaten or potentially threaten natural areas, agricultural lands, and gardens. This is a working list of species which have escaped from landscaping, reclamation projects, and agricultural activity. All problem plants may not be included; contact the Colorado Dept. of Agriculture for more information (see references below). Some drought resistent, well adapted exotic plants suggested for landscaping survive successfully outside cultivation. If you are unsure about introducing a new plant into your garden or reclamation/restoration plans, maintain a conservative approach. Try to research a new plant thoroughly before using it, or omit it from your plans. While there are thousands of introduced plants which pose no threats, there are some that become invasive, displacing and outcompeting native vegetation, and cost land managers time and money to deal with. If you introduce a plant and notice it becoming aggressive and invasive, remove it and report your experience to us, your county extension agent, and the grower. If you see a plant for sale that is listed on the Colorado Noxious Weed List, please report it to the CO Dept. of Ag. (Jerry Cochran, Nursery Specialist; 303.239.4153). This list will be updated periodically as new information is received.

Improving the Quality of Wildflower Seeds for Commercial Users©
Improving the Quality of Wildflower Seeds for Commercial Users 179 Improving the Quality of Wildflower Seeds for Commercial Users© Natasha Ryan Scotia Seeds, Mavisbank, Farnell, Brechin, Angus, DD9 6TR Email: [email protected] INTRODUCTION Over the past 25 years or so there has been a great increase in the use of seeds of native wildflower species in the United Kingdom, as in other European countries and North America. Wildflowers have been increasingly sown in urban regenera- tion and civil engineering projects for their attractive appearance and low mainte- nance requirements. Wildflowers also attract wildlife so are used in habitat restora- tion, community biodiversity projects and individual gardens and estates. The use of wildflower species in agri-environment schemes is also popular. The increased use of wildflowers has been followed by an increase in commercial production and trade of approximately 200 species of plants, most of which are new to commercial trading. In many cases seeds are not sold directly to the end users but may be sold to commercial growers to be raised as plants before being sold on. “Traditional” agricultural and ornamental crop seeds are subject to quality regu- lations. Seed lots are sampled and subject to germination testing, purity analysis, and varietal testing. However, in the U.K., regulation does not extend to wildflower species. Some species are coincidentally covered by agricultural seed legislation, in the form of the Fodder Seeds Regulations. This legislation covers some species which are also traded as “wild” material such as Lotus corniculatus. However, the requirement for registered cultivars means that natural populations cannot possi- bly conform to varietal standards. -
Ox-Eye Daisy, Leucanthemum Vulgare
A Horticulture Information article from the Wisconsin Master Gardener website, posted 5 June 2009 Ox-Eye Daisy, Leucanthemum vulgare From late spring into summer, pretty white daisies dance on the ends of long stems in gardens, meadows, dry fi elds, roadsides and railroad right- of-ways and even waste areas. Ox-eye daisy, Leucanthemum vulgare (= Chrysanthemum leucanthemum), is an attractive, but somewhat weedy, short-lived herbaceous perennial from the British Isles, Europe and north- ern Asia. Hardy in zones 3-9, it is now naturalized throughout the US and southern Canada. The showy fl owers make this a popular garden plant. The young leaves can be used in salads and a tea made from the whole plant has been used as a home remedy to treat asthma and whooping cough. It is often confused with the ornamental Shasta daisy (L. x super- bum or C. maximum), but that plant is more robust and has larger fl owers that bloom later on heavier stems. Scentless chamomile (Matricaria ma- ritima) is another similar plant, but it is an annual that has smaller fl owers and much more fi nely dissected leaves. A large patch of ox-eye daisy. Also known as marguerite, fi eld daisy, white daisy, moon daisy, moon-penny, dog daisy, and many other common names, this plant in the family Asteraceae (Com- positae) was introduced to North America a long time ago and has become naturalized in a variety of plant communities, displacing native plant species in some areas. It is not a threat to intact prairies and savannas, but readily invades disturbed ground. -
