Podocarpus macrophylla Pringles 1-gal
The Pringles podocarpus in its small 1-gallon container is a great choice as a thriller for a larger pot because it doesn't grow that fast. You might get 3-5 years of life before the Pringles is too big for the pot and needs to be transplanted elsewhere.
And, who came up with such a cute name ... Pringles. Seriously, you want to buy this plant just so you can tell your friends you have a Pringles Podocarpus in your pot.
