Itea; Ilex; Indigofera; Isopogon; Ixora:
Itea ilicifolia. Not as widely grown as it could be, this evergreen shrub has many uses - especially in a sheltered place.
Ilex – Holly: - Normally a small tree, rather than shrub. the hollies also have a few dwarf types that truly make them shrubs. The larger Holly Bushes are invaluable for their foliage and berries. they also make a good clipped hedge.
Indigofera: - Interesting shrub group with pea0like flowers and varied foliage. Can be grown as stand alone shrubs - or trained against trellis or wall.
Isopogon – Cone Brush – Drumsticks: - Typical Australian shrub, with attractive - if slightly inusual - flowers. Tender - or can be grown under glass.
Itea: - Evergreen foliage with pendulous flowers. The specimen in the picture was grown over an arch - very effectively. The evergreen foliage can suffer a little in hard frosts.
Ixora: - An evergreen group of shrubs for more tropical places, where they are often grown as hedges - full of flower for most of the time and responding to being clipped regularly. Colder countries will have to provide glasshouse protection.
