I finally located Golden Gate rose. The Antique Rose Emporium had it in stock. I called them on May 14th, 2018 , placed an order. It was actually there last week for 2018 season for shipping. I was lucky that I called on right time. They sold rose as own root in 2 gallon pot.
Rose arrived on May 18th, 2018 on a hot day. Healthy plant, great packaging .I Planted the rose same evening , watered well after planting.
Here is picture of 1st flower on June 4th, 2018
I have pinched remaining buds, I will keep pinching buds through this year so plant will put its energy on growth and good root system development.
