Pros:
- Massive quantities of flowers for about 3 months
- Bees love the blooms
- The plant doesn't need any care to thrive
- We've transplanted a few of the seedlings. They're true to their parent in terms of color, but the parents seems like a double bloom and the children seem like single bloom
- If you want a hedge, this seems like a good option
Cons:
- Seeds! So many seeds. Each of its hundreds (thousands?) of flowers will produce 10+ seeds. They all don't germinate, but it's a numbers game. If you want to avoid pulling volunteers up you're best off pulling the seed pods off the plant before they open on their own
I pulled ~2 gallons of seed pods off a week prior to this picture. My wife dumped them in the compost, so no epic 5+ gallon photo ๐ญ
That's a very nice looking area. Your Roe of Sharon is much better pruned than ours - we more or less let it to wild and trim the sides if it's getting unruley. I also suspect yours is more mature based on the size of the trunk towards the top. Ours is still flexible enough that I can grab an offshoot and pull the whole branch it's connected to down.
Looking at yours, and thinking about our 3' tall one we grew from seed, I think our original plant is really a collection of a bunch of individual plants that were grown in a common pot.
