I questioned whether native butterflies would lay eggs on the giant milkweed and whether the caterpillars would feed on such a large import, but the answer is yes on both counts.

Similarly, do monarchs like giant milkweed?
Yes, milkweed attracts monarch butterflies, but its story is more complicated.

- Overwinter in pots for annual zones. Be wary of overwatering.
- Mix perlite or sand into potting soil to improve drainage.
- If you don't want additional seedlings next spring, simply cut off the seed pods before they pop open or tie organza bags over them to collect milkweed tree seeds.
Additionally, do monarch caterpillars kill milkweed?
Do the monarch caterpillars harm milkweed plants — they eat it after all. I couldn't find any conclusive answer to this.

They really only eat milkweed, which is why the Monarch butterflies find the milkweed to lay their eggs on it.
