The Q&A Archives: What is on my cannon flower

Question: I planted my cannon this year and many of them are flowering. On some of them the flowering part looks like an acorn-what is it? Is that seeds and do cannons only have seeds every other year?

Answer: What you are seeing is the developing fruit, or rusty cannonball, as it is commonly called. As it matures it will contain seeds. The flowers are pollinated by bees and if properly pollenated, you'll see lots of cannonballs, filled with seeds. If the flowers are not pollenated, they won't develop cannonballs.

Enjoy your cannonball tree!
