'J.P. Connell' rose Reviews & Comments
HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

Difficult to imagine from the parentage stated in Modern Roses 10, isn't it? However, if we modify the pollen parent from 'Von Scharnhorst' to 'open-pollinated seedling of Von Scharnhorst' (as stated in the note) then it is quite possible that a very hardy nearby rose in the Experimantal Station played a role.

In Denver Colorado, JP Connell blooms are pale yellow and will have 2-3 flushes during the season. It appears to tolerate some shade and grows in a difficult location, next to the street and under a locust tree. It does suffer some winter die-back. This is a great rose for difficult conditions.

I have had J.P. Connell in my garden for 7 years - no winter protection - disease free. It was suffering from 4 years of neglect and was rescued late last fall and relocated. This summer she put out numerous sturdy new canes, grew to 4 feet and bloomed well until hard frost. Hopefully next year she'll do even better.
