    This is the crested version of Euphorbia flanaganii. It does well in full sun or partial shade but can burn in very intense sun. It is a fairly fast grower when in favorable conditions.

    One of two different crested forms of this species, and orders of magnitude more common in cultivation than a head crest. This form is a crested version of one of the narrow branches of this species (propagated easily from cuttings). A head crest is a crested version of the much wider main stem (and a very rare chance occurrence among seedlings).

    Mature plants resemble a sort of green coral, and may grow to 8 inches or wider. Reversions to the normal (uncrested) version may appear intermittently and these may sprout new heads with their own radiating arms (easily removed and rooted for propagation), so maintaining an entirely crested plant may require semi regular pruning.
