That is the same one I have Jacquie,
Thank you so much for sharing your beautiful pictures of beautiful flowers; yet alas and alack, this is not the true bright yellow Grandma had;...........gosh why didn't Mom or one of our other family members keep her beauties through the years??? No one loved plants more then Grandma back than, then Grandma I suppose......
It stayed in the Genes-pool in me though later on! It was just to late to save her true Yellow Beauties of this incredible plant.
