Dear Rose Enthusiasts,
Jeekin Lau, Ellen Young, Zainab Mansur, Stella Kang, and I participated in the American Society of Horticultural Sciences annual meeting in Washington DC this past week. We were quite busy as among us we presented 7 talks and 12 posters. It was a great meeting with about 1,000 attendees from all areas or Horticulture.
Dear Rose Enthusiasts,
I was looking through the rose seedlings in the greenhouse and noticed this micro mini rose seedling derived from a cross with ‘Little Chief’ as a grandparent. The flower is about 1/4″ across. I wonder if it would survive in the field? We have been potting up the seedlings still left in the flats into pots to grow them a bit. Hopefully they will be big enough to plant into the field this fall and then we can see if they do well with black spot, cercospora, and plenty of heat.
Dear Rose Enthusiasts,
Here is the group of people dedicated to keeping our roses as free as virus as possible. This NCPN (National Clean Plant Network) group includes people representing the rose propagators, rose nurseries, rose breeders, rose research and extension, public gardens and rosarians throughout the country.

Dear Rose Enthusiasts,
We had a wonderful meeting of the National Clean Plant Network at the beautiful Los Angeles Arboretum. The staff and the facilities were excellent and the free roaming peacocks made for quite a colorful background.
As a group we have made tremendous progress in the 3 years we have been active. Among the tasks we have accomplished are the renovation of the clean rose collection at the Foundation Plant Services in Davis, California, the definition of the important viral threats to the industry and the updating of the protocols to detect them, the expansion of the collection to include the commercially important and non patented modern and old rose garden varieties, and the development of an outreach program to spread the word of how important this program is to the health of the industry.
Mosaic caused by a coinfection of two viruses – Apple Mosaic Virus (ApMV) and Prunus Necrotic ringspot Virus (PNRSV). Although the visual symptom is mild, the viruses generally decrease the plant growth as well as lower flower production.
Dear Rose Enthusiasts,
Ellen Young and Jeekin Lau went to Tennessee to plant some roses..well perhaps a lot of roses – at the station in Crossville, Tennessee where they have great Rose Rosette Disease. Hopefully the results of this trial will lead us to the genes that condition resistance to RRD. Mark Windham and his crew did a great job. They are always a delight to work with!
