I planted a Maypop two years ago (seeding purchased from Logee's).
First year (2019), we got a handful of fruits, but they fruited late and did not ripen before frost hit. I think one had some pulp. I thought maybe it needed a polination partner (conflicting info on whether or not it's needed). So I ordered another seedling and planted it in the fall. No suckers the first year.
Second year (2020), our first plant came back after the beginning of summer. The second planting got bit by rabbit or rodent after emerging, and struggled most of the year. I think it had a few leaves on it all year. A few suckers here and there toward the end of the growing season. We ate these, because they are super tasty.
Third year (2021), a new growth appeared about 2 meters from the original planting. We got lots of rain in the spring and it really thrived. But I didn't go into the garden much because of the weather. But it's like Summer of the Triffids out there. Maypop suckers are coming up everywhere in a 3m radius from the original plant. I'm not even sure if the second planting came back or not (I think so). On the plus side we got many fruits and they taste like green-apple Jolly Ranchers with varying degrees of sweetness.
We pick and eat the suckers whenever we go in the garden, but they're really everywhere.
