    • The airy white umbels of viburnums (mostly Viburnum dilatatum – linden viburnum & some Viburnum dentatum – arrowwood viburnum) are found throughout the Gardens and Estate this week.
    • The yellow, green & orange flowers of tulip poplars (Liriodendron tulipifera) can be seen on the trees & also on the ground.  Look up or down to see them.
    • The tiny white-to-pale-pink daisies of fleabane (Erigeron annuus) are blooming throughout the Estate. 
    • The purple, lavender, and white flowers of Dame’s rocket (Hesperis matronalis) are present in lesser or greater abundance in the gardens and fields.
    • White clover (Trifolium repens) in the fields and lawns is providing nectar and pollen for the pollinators and nitrogen for the soil.


  • Peonies are all the rage in the Lower Peonie Garden. Breathtaking!
