The star turn in the Mamaroneck garden right now are these blue Irises. They are in the border at the front of the house so they are a cool welcoming sight as you enter the driveway. The color looks particularly good combined with the lime buds of the hydrangeas that they are planted with.
I've no idea what kind they are, Heidi tells me she got them as a gift from a neighbour and she planted them about four years ago but this is definitely their best year- there are a lot of them. Coincidentally Blue Iris just happens to be Pantone's Color of the Year so this is not just a cool color for right now while the temperatures are soaring into the nineties, its a cool color for 2008.
