[IBC] Adventitious Roots
In a message dated 8/26/05 12:03:06 AM, Steve writes:
They are referred to strangler fig I believe. Not correct. Roots coming from the upper part of a plant are called adventitious. A ficus with a number of extra trunks formed by adventitious roots is called a banyan. In bonsai they are usually considered very desirable. Strangler fig, Ficus aurea, is a particular species found in Florida. It is a sort of parasite. Its seeds sprout on the forest floor. Then the seedling finds the nearest tree and climbs up it as a vine, to reach the light. As it gets to the top, it grows more stems and branches around the host tree, eventually smothering it and becoming a free-standing tree. Ficus aurea can be grown as a bonsai. I presume they stake it to the desired height until it stands on its own, or grow it on a sacrifice tree to get the multiple trunks.

Dear All
Strangler fig, Ficus aurea, is a particular species found in Florida. It is a sort of parasite. Its seeds sprout on the forest floor. Then the seedling Also not so true... In my experience with the South African stranglers they are not parasitic at all. A parasite is "a plant or animal living in or on another and drawing nutriment from it" (ancient, 1942, Pocket Oxford!). Parasitic plants have specialized structures that tap into the host plant and steal water and or nutrients from the host plant's vessel system. A plant that is just using another for support and not sustenance is not parasitic. finds the nearest tree and climbs up it as a vine, to reach the light.

Ficus aurea can be grown as Our strangles start off as seedlings in forks of branches and their roots grow down to the soil. A net of roots is created, surrounding the support plant, which effectively ring barks the tree and eventually kills it. own, or grow it on a sacrifice tree to get the multiple trunks. You don't need to use a living tree. You can develop a strangler over a stump of one of you failed bonsai attempts. Design wise you want to create a more tropical feel rather than a exposed mountain tree that is often achieved with phoenix grafting. I have grown a root-over-tree (as opposed to root-over-rock) using a dead Olive stump and a living Natal Wild Fig (Ficus natalensis). The roots have bonded well and the canopy is now being developed.

A plant that is just using another for support and not sustenance is not parasitic. According to Nelson's "Trees of Florida," Strangler Fig (Ficus aurea) often begins in the upper parts of a tree as an epiphyte -- it gets its water and nutrients from the air -- though it can grow by seed from the ground as well. It is NOT a parasite, but then, Iris said it is "sort of" a parasite. If an epiphyte, it grows in both directions, sending roots down and branches up, wrapping itself around trees. When the tree eventually dies -- "choked," some say, by the "strangling" roots -- it rots away in tropical humidity, leaving the roots standing upright around a hollow. Or, it may just outlive its host, with the same results. F. aurea is relatively common in the lower third of Florida.
