    When I spied this plant at a local garden center, I knew I had to have it. Not only were the blooms beautiful, but being married to my soulmate, it was fitting to be planted in my garden.

    I didn't give it the spot where it should have been, with lots of water and after I planted it and it bloomed in 2006; it started to decline.

    I keep thinking that if I find 'Soulmate' again, that I'd make it the perfect spot to keep growing and blooming for years. Maybe I'll put those 'water crystals' into the soil and add extra peat in the hole and top it with wood mulch for sure.
