Can you post a photo of it? Is it all yellow or does it have other colors in it? How many petals does it have? We really would need to see it to help.

By doing a quick search on HMFRoses, with the search criteria being that the name contains "love" and that the flower color is "any yellow" I have found a couple of possibilities. Since you didn't mention any color but yellow, I ignored the multicolored roses - such as yellow with pink edges.

'Always Love You' is a floribunda - officially deep yellow, but some of the photos show a medium yellow.

'Summer Love' is a hybrid tea - listed as being medium yellow and as having large flowers. There are only a couple of photos on HMF, but it does seem to be widely available.

If you could provide more information regarding the rose, or a photo, I think people on the forum could give you better guesses at its identity.

Any chance it could be one of the "Easy-To-Love" series? Fits the time frame, though all are still offered. Easy Going & Julia Child are yellow floribundas & could easily reach 5'. Of the two, Easy Going's flowers are reputed to be larger, though I'm not familiar with this rose. Julia Child is such a great favorite of many on this forum that I brought in two this year & now can be added to her fan list.

Take at look them at the link below.
