Gardeners' Notes:

Positive Opoetree On Jun 4, 2011, Opoetree from Oak View, CA wrote:

Yucca grows very well in inland southern California. The blooms are very exciting to watch as the stem develops...grows taller...and taller...and taller! The coloring of the spike is breathtaking and the blooms are absolutely magnificent!

Positive melody On Feb 2, 2005, melody from Benton, KY (Zone 7a) wrote:

This is a very showy yucca, especially if seen in masses on a hillside while in full bloom.

The shame is, the plants die after flowering.

Most often found on stoney slopes in chaparral in Southern CA and in Baja CA.

Neutral palmbob On Mar 8, 2004, palmbob from Acton, CA (Zone 8b) wrote:

Local Yucca to Southern California and Baja. Has thin, flat, stiff leaves that end in nasty spine. Flowers huge and up to 15' above plant. Stemless Yucca. Kind of a messy looking plant sometimes, but if groomed (ouch!) can be a nice specimen.
