Long Description:
Moreton Bay Fig
Ficus macrophylla
The remarkable large tree to the north of the museum is a Moreton
Bay Fig tree, which—like most of the other large trees in the Prado
area of Balboa Park—was planted in preparation for the 1915
exposition. The 1914 planting list for the exposition shows a
five-gallon fig tree planted at this location. Since it was a few
years old at the time it was planted, its age should probably be
computed from about 1910, making over 90 years old in 2002. While
many people would like to attribute its planting to Kate Sessions,
San Diego's pioneer horticulturist and street tree planter, there
is no documentation to verify this claim.
This tree is listed in the California Registry of Big Trees as one
of the champion trees of the state. According to the registry, the
tree measured in 1996 about 78 feet (24 meters) high, with a crown
width of 123 feet (37 m) and a trunk girth of 486 inches (12.3 m).
It shares the title for this species with the famous Moreton Bay
Fig tree of Santa Barbara, California, which has a broader canopy
but is not as high.
Many people who grew up in San Diego remember climbing around the
roots of this tree as children, while their families enjoyed
picnics in the cool shade. Unfortunately, heavy foot traffic caused
soil compaction and damage to the delicate surface-feeding roots of
the tree, preventing it from obtaining nutrients and water, and the
tree began to decline. It was trimmed and fenced off in 1989, mulch
was allowed to accumulate, and the tree has recovered and once
again shows thick, glossy foliage. As it has recovered it has begun
to show the aerial roots that are characteristic of fig trees. In
the wild, these roots would have been growing since the early youth
of the tree, and would have reached the ground and developed into
stout, woody props to help support the heavy branches.
The small dry fruits of the Moreton Bay Fig--like those of other
figs--are actually composed of hundreds of tiny flowers completely
enclosed within the inverted fleshy tissue of the receptacle upon
which they rest. A tiny hole (called an ostiole) in the tip of the
fruit allows minute symbiotic wasps, which pollinate and lay their
eggs within the flowers, to enter and leave the structure.
Ficus macrophylla is a native of east Australia. When it is grown
in an open area where it can spread, the Moreton Bay Fig may become
as much as 150 feet wide; but crowded in its natural forest
habitat--or near buildings in an urban setting--it tends to grow
tall and narrow.
