  • Posted by zuzu (Northern California - Zone 9a) on Dec 17, 2019 12:52 AM concerning plant:
    Even with the most diligent pruning, Yves Piaget usually has an ungainly and asymmetrical habit. The thick branches persist in jutting out horizontally, so the bush is almost always wider than it is tall. In addition, it has a cloying anise scent, which is a fragrance I don't particularly like. In spite of these negative features, however, I'm happy to grow it just for the blooms. They are extra-large cupped blooms with about 80 beautifully ruffled petals.
