Just a quick line about Albucas. I currently grow three species all of which have proved hardy here. Albuca humilis is a dwarf form, up to 8 inches, with white flowers striped green. Albuca shawii is taller at 15 inches plus with yellow flowers striped green and Albuca nykensis has not yet flowered with me but size wise it is a little taller than A. shawii. Regards. Ian.
