IMPORTANT READ BEFORE Make your Grafting Request Order

Spring Grafted Trees should be ready the following Fall. Deadline is May 01

Late Summer & Fall Grafted Trees should be ready the following Spring. Deadline is October 01


A Pre-Order Grafting Request is an order for us to produce the specific tree that we don't currently have available in stock. We must graft the tree and then it must go through a multi-month process to heal and grow. Only Once the small tree has completed two flushes of growth since it was grafted do we consider it ready to leave our nursery.

Zill O-15 was a seedling of Jakarta from the breeding program of Gary Zill in Boynton Beach, FL.

It is a medium-sized mango, ovately shaped and turning yellow at maturity. The flesh is fiberless, yellow, and firm. The flavor excellent,though can be  highly resinous, reminiscent of Jakarta but probably sweeter, belonging in the Indian/West Indian flavor class.

The original tree is productive, but the fruit tend to ripen in a very short span, only a couple weeks.

We topworked a tree into O-15 in 2017 for evaluation. In 2019 this tree flowered and set fruit well, but did not retain any of its fruit to maturity. It finally fruited well in 2020 and had multiple crops. The tree has fruited each year since. Fruit quality has been inconsistent, with some specimens being outstanding and some being washed out. O-15 tends to have physiological issues with stem end rots and large anthracnose spots on the top of the fruit being a problem. We are hoping this will be less of an issue as the tree gets older.


Flavor: Indian/West Indian

Country: Florida - USA
