Albizzia julibrissin ‘Fan Silk’ (syn. FLAME) – This cultivar of Mimosa or Silk Tree features fluffy, incredibly bright rose-pink flowers in summer. It is deciduous with very fine fern-like green compound foliage that shifts to gold in the fall. Drought tolerant once established. Attracts both bees and butterflies. Grows 20′ high by 12 to 20′ wide. Hardy to zone 6-7.
Yucca aloifolia ‘Purpurea’ (syn. ‘Blue Boy’) – The main attraction of this evergreen shrub are the arching grey-green leaf blades distinctly overlaid with a dusky purple (very prominent in summer). It bears spikes of white flowers (sometimes purple-tinted) from summer into autumn. Prefers full sun with good soil drainage. Grows 2-6′ high by 3′ wide. Hardy to zone 6.
Hedychium gardnerianum – Kahili Ginger is a common sight at tropical destinations across the globe but it also finds its way into local exotic gardens. It is best grown in large containers (overwintered in a cool greenhouse) where the fragrant racemes of lemon yellow (with red stamens) can be appreciated. Flowers late summer into early autumn. Grows 4-6′ high by 3′ wide. Zone 9.
Poncirus trifoliata ‘Flying Dragon’ (syn. Citrus trifoliata) – The Japanese Hardy Orange is a beautiful container specimen and often used as a rootstock for citrus plants. It is deciduous, forming a large shrub or small tree with green leaflets, twisted stems and prominent thorns. Fragrant white flowers are borne in late spring followed by orange golf-balled sized fruit. Grows 5-10′ high. Z5.
Eucomis ALOHA LILY ‘Leia’ – A hybrid Pineapple Lily (possibly a E. zambesiaca x E. vandermerwei cross) with spikes of fragrant rosy-purple flowers in late summer (topped with green bracts). These are nicely contrasted by lightly mottled green foliage with wavy margins. Easily overwintered by growing in containers and storing in a cool greenhouse. Grows 15″ high. Hardy to zone 7.
