Hi Busybee! I have searched all of my resources for roses, and have only come up with three roses that meet your criteria. Not knowing what type of rose it was, or anything more about it, it will difficult to search much further. I reviewed the site on the 2006 Chelsea Flower Show and did not find reference to anything resembling what you describe. Here are the three I have found:
- "AUSfather" - a shrub rose also known as "Charles Austin" (father of rose breeder David Austin). It was bred in 1973 in the UK. It is an apricot blend, with strong fruity fragrance, and flowers that are up to four inches with 70 petals. It can grow to a height of 5-10 feet, and a width of 4-6 feet.
- "Our Daughter" - a floribunda patio rose bred in 2001 in the UK by breeder W.E. Bossum. It is a medium pink, with small fragrant blooms with 41 petals. It can grow to a height of 2 feet.
- "Father David's Rose" - a species rose also known as "rosa Davidii", discovered in 1908. It has small light pink flowers and can grow up to six fee tall and twelve feet around.
If you can remember what part of the Chelsea Flower Show you saw it in, or any other details, I would be able to look further.
If you are not able to find the right one, may I suggest seeing if there is a rose with your father's name? There are also several roses with names like "In Memory", etc.
Let me know what you think, and we can look further. Not to worry, we will find something. I know how it is to want to plant something in someone's memory. I planted an entire rose garden in memory of my grandfather (he was a rosarian and taught me much of what I know). I know there are others on the forum who have done similar.
Hope to hear back from you.
