Glasnevin is a semi-evergreen climber. It's foliage is a lovely mid green and leaves are long and pointed at the tips. In the summer months is when this plant really comes alive, clusters of tiny purple flowers, with bright yellow centres cover this climber. The ideal position for this would be  climbing up a trellis or over a pergola near a garden seating area as the flowers have a lovely scent.
