Senna Multiglandulosa

Growing Senna

Senna prefers full sun and can be sensitive to frost but is otherwise quite hardy. Our original tree has grown wild in a neglected corner of the property with poor soil, no irrigation and plenty of weed competition. In some areas it is known to be quite invasive (as many nitrogen fixers can be), however we have not observed that to be the case here.

While we predominantly grow Senna for its nitrogen fixing benefits, the seed pods are apparently edible although not that tasty – better used as stock fodder.

Using Senna

We are currently using Senna as a smaller growing alternative to Tagasaste in some areas with a view to being able to use the pods for animal feed when we add them to our system. Their growth is not particularly dense making them good for providing dappled shade for protecting sensitive plants from harsh mid-summer sun. They also seem less prone to snail attack than Tagasaste.
