Tree Heath 'Estrella Gold' One of the best tree heaths, Erica arborea Estrella Gold is a small to medium-sized, slow-growing, though sturdy, evergreen shrub with an upright habit. New foliage is bright yellow, turning green in summer, although the tips of the leaves retain the yellow colouring. In April and May, the shrub carries long panicles of scented, white flowers. Ideal in a border with acid soil, or for making a taller punctuation point in a heather bed. Tree Heath Estrella Gold holds the RHS Award of Garden Merit.
