Milk weeds provide food and a home for the monach caterpillar.
We allow patches of milkweed to grow among our gardens to attract butterflies and give a home to the beautiful monarch. The bioshelter at Three Sisters Farm was built in 1988 with funding assistance from The Pennsylvania Energy Office. Funding ultimately originated from a federal lawsuit to recover oil overcharges from major oil companies. The partners of Three Sisters Farm contributed matching funds in cash and labor and bank loans. The bioshelter integrates many farm components into one building.
