Rilas Red is a finely cut lace leaf which is similar to Red Filigree Lace. Rilas Red is fairly heat and sun tolerant...so it tends to hold it's color well into the summer. The purple-crimson lace leaves darken in summer, and turn a very nice orange red in the fall. A very delicate and slow grower, this maple does best with morning sun and afternoon shade that is out of the wind placement. This maple can be difficult to grow (but well worth the effort!).
