Arizona Madrone (Arizonica)

The Arizona Madrone (Arizonica) is generally described as a perennial tree. This is native to the U.S. (United States) has its most active growth period in the spring and summer and fall . The Arizona Madrone (Arizonica) has dark green foliage and inconspicuous white flowers, with a moderate amount of conspicuous red fruits or seeds. The greatest bloom is usually observed in the late spring, with fruit and seed production starting in the summer and continuing until fall. Leaves are retained year to year. The Arizona Madrone (Arizonica) has a long life span relative to most other plant species and a slow growth rate. At maturity, the typical Arizona Madrone (Arizonica) will reach up to 45 feet high, with a maximum height at 20 years of 20 feet.

The Arizona Madrone (Arizonica) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 7°F. has high tolerance to drought and restricted water conditions.
