The tulips must have been prechilled? Looks like Tulipa 'Orange Emperor'..just maybe. Very pretty combination the blue For-Get -Me-Nots and the orange tulips. It sure is a wonderful place to be...I envy you ;-) I 'm wondering what is planted in the bed after all this beauty is gone.
They change it a lot. I have a picture from August 2008 of the same area. This picture is from standing just by those beds in the tulip picture but instead of North to South, it is West to East. As you can see orange zinnias rule this day.
Oh BTW, they are Perestroyka tulips. And they do keep them in cold storage for awhile before planting them in pots and in beds. Sadly, though they buy close to 100,000 bulbs per year, many are tossed after they flower.
Per the Filoli site talking of the 2007 season
"Filoli has planted approximately 88,000 bulbs in the garden this spring. In particular, the Sunken Garden will have an amazing display of 4,100 salmon colored ‘Perestroyka’ tulips," noted Jim Salyards, Greenhouse Manager at Filoli. Salyards also noted that, "In total, 70 varieties of tulips and 27 varieties of Narcissus will be on display, as well as a mixture of annuals such as pansies and violas."
Here is another picture of same area but taken standing South of original photo area and looking North. You can see the wild area in back of the estate house which to me is even more beautiful than the formal gardens. In fact as I wonder aorund there I am forever reminding myself to look up and out beyond the gardens for the true beauty of the area.
