3 x Grandma's white perennial flower SNOW IN SUMMER flowering ground cover

You get three live plants as shown in pictures 3 and 4 they come to you as long burritos with roots and dirt under the newspaper and live plant on top ... Easy to plant plugs you put right into the ground. Super easy to grow and very forgiving .... does NOT need rich soil or enriched soil. Native to the alps ....zones 2-7. These are the direct descendants of my grandmother's plants so they've been in my family for total of nearly 80 years .. 57 seven of those years we're at the house I grew up in. Stick them in the ground and keep them moist ...watered .... until they have had several weeks to spread out roots and adjust to transplanting. Loves rocks and rock gardens ....spreads outward from the center. We had this in large patches between trees. Thick carpet of silvery blue leaves that never disappear .... plant stays silvery green all winter long under the snow ! Carpets of sweet smelling white flowers from approx. May 15th to June 25th ish.... My favorite perennial !
