"Penrose" is the study name given to a climbing Hybrid Tea rose found by Penny Hooper when she and her family bought their home, 'Penrose', near the Swan River in Guildford, Western Australia. "Penrose" matches the detailed description in Frederick H. Howard's patent application for 'Indian Summer'. After Hillary Merrifield suggested 'Indian Summer' as a possible identity for "Penrose", it was discovered that there are named plants of 'Indian Summer' extant in Perth and when compared, the two roses were found to be identical.
