'American Pillar' rose Description

My HMF:

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.

Notes:

Arena Rose Co.'s Catalog 2000 says: Beloved throughout France and making a comeback here in the U.S., American Pillar explodes each spring with a profusion of carmine-pink single blooms in huge clusters. A brushing of white at the base of the petals offsets a large eye of golden stamens...
For clarification of parentage, see References. Recent references citiing 'Red Letter Day' as the pollen parent are probably mistaken. Red Letter Day was introduced in 1914, 16 years after Van Fleet bred this rose on a different continent.
