1. Baptisia collection expands at the OPGC

    Jul 1, 2015

    Baptisia is one of the genera maintained at the OPGC.  This native North American genus consists of approximately 30 species distribued mainly in the Eastern and Southeaster USA.  The collection had originally been developed at the North Central Regional Plant Introduction Station in Ames, Iowa, but has since be transferred to the OPGC.  Recently, the last shipment of seeds were received and curation of the collection moves forward.

  2. Juliana Espindola joins OPGC as a visiting scholar

    Jul 1, 2015

    Juliana Espindola from the Universidade Federal de Lavras in Brazil has joined the OPGC as a visiting scholar for 9 months to study seed development in Phlox. Juliana is a PhD candidate in Brazil and is pursuing studies on seed quality and germination. Her work at the OPGC will focus on documenting the development of seeds from flower formation to seed maturation. Phlox seed production is a challenge and availability of high-quality seed is very limited.  Juliana will help define the key parameters involved in seed production and maturation.

  3. The OPGC at Cultivate'14

    Jul 31, 2014

    Every July, the OPGC participates in the largest horticultural trade show and educational event, Cultivate'14 (formerly the OFA Short Course and Trade Show).  Our presence at the trade show and in educational sessions provides us with a forum to promote our activities and maintain connections with our stakeholders.  Our small booth highlighted Phlox as our theme genus for this year.  We also contributed presentations on the opportunities and challenges in Phlox as garden plants as well as on the contributions the OPGC makes to the floriculture and nursery industry.

  4. Lilies in Bloom

    Jul 31, 2014

    The genus Lilium is one of our priorities for conservation and study.  Last year (2013) we initiated a collaborative study with Prof. William Miller of Cornell University to assess the garden performance of selected lily cultivars that have previously shown some potential as perennial garden plants in different parts of the USA.

  5. Chadwick Arboretum Green Roof Offers Great View of the OPGC!

    Jul 31, 2014

    The OPGC's backyard offers a colorful and enticing view from the beautiful new green roof installed on Howlett Hall as part of the Chadwick Arboretum and Learning Gardens' programs.  The view from this roof includes our high tunnel and the many raised beds that this year, 2014, are teeming with phlox of many types.  The phlox collection includes plants derived from material collected in the wild, as well as representative cultivars.

  6. Butterflies Thrive at the OPGC

    Jul 31, 2014

    Controlled pollination of our acessions is critical for the production of seeds consistent with the genetic charateristics of the original population.  Bumblebees are our principal pollinators, but unfortunately they do not typically pollinate flowers of Phlox, one of our priority genera.  In the wild, phlox are generally pollinated by members of the Lepidoptera, the moths and butterflies. The reason for this is that phlox flowers have a very narrow corolla tube.

  7. Phlox chosen as the theme genus for 2014

    May 25, 2014

    Continuing our tradition of designating one of our priority genera as a theme for the year, we have chosen Phlox for 2014. This genus has been the subject of intensive research and development at the OPGC for the past 4 years and our germplasm collection has expanded from an initial set of 2 accessions 5 years ago, to over 400 accessions of both wild-collected material and cultivars in our current, and expanding collection.

  8. The OPGC booth at OFA Trade Show features Coreopsis

    Jul 19, 2013

    In keeping with our focus on Coreopsis for 2013, we chose to showcase flowers of this genus in our informational trade show booth during the OFA Trade Show, 14-16 July.  The booth provides us an opportunity to tell our story to industry stakeholders and to make contacts with visitors from around the world who attend the show.  The booth was manned by OPGC staff and students who serve as ambassadors for our mission to provide genetic resources that benefit the industry and scientific research.

  9. Coreopsis story in OFA Bulletin

    Jul 19, 2013

    The OPGC's focus on Coreopsis for 2013 was featured in an article about this genus that appeared in the March/April 2013 issue of the OFA Bulletin, the official publication of the Association of Horticulture Professionals.  The article describes the diversity found in Coreopsis, focusing on the development of the many new colorful cultivars developed by interspecific hybridization.  This native North American genus has seen a rapid expansion of new cultivars over the last 10 years highlighting the genetic diversity that can be exploited to develop new products.

  10. Coreopsis chosen as signature genus for 2013

    Jan 11, 2013

    Following the selection of Begonia as the first signature genus for the OPGC in 2012, Coreopsis has now been chosen as the focus for 2013.  This means that throughout the year various activities will emphasize the attributes and potential of this widespread North American genus.  The activities will include presentations to growers and gardeners, articles in the popular media, enhanced content in this website, estensive plantings of the species in the OPGC nursery and general landscape, and increased characterization and evaluation of germplasm.
