Gardeners' Notes:

I had a King's Ransom for several years. I am always trying to find yellow hybrid teas that can be made to survive our NE Wisconsin winters (zone 5). This one, if buried in ground, would survive, but only the very bottom of a few of the stems would be alive when the plant was unburied int he spring.

My particular King's Ransom had a poor growth habit in that the stems were commonly not strong enough to hold the bloom up, and so the flowers would droop and not look good either on the plant or in a vase.

Nice yellow Hybrid Tea, but it won't winter over in Maine.
