What is significant about Grandma's Yellow Rose is that it does not incur black spot so you do not have to spray it as much as regular roses. It takes root very well and performs well in alkaline clay soils. Another wonderful aspect of the rose is that it blooms from Spring 'til Frost! Now that would be a nice little gift for the garden during the scorching summer days.
I need to find out where to purchase Grandma's Yellow Rose for farmer-man and my's next Valentine. We buy a rose bush each Valentine's. Then we'll know how many years we have been together. Ha! Interesting enough, the article says it is also a great "Valentine's Rose" because of Grandma's long stem and flower design. Very fitting if you ask me!
There's Grandma Tillie!
