Always a drama queen, Pride of Madeira sends out sublime giant lilac flower spikes. Foliage color and texture play a large part in this design. Here, the chartreuse blossoms of the Euphorbia characias play against the black rosettes of Aeonium arboretum 'Zwartkop', the spear-like leaves of the Echium candicans and the fleshy blue spikes of Senecio mandraliscae.
