Collection: Penstemon

Penstemon are clump-forming perennials valued for their long season of tubular flowers and their usefulness as structural, repeat flowering border plants. Flower spikes rise above leafy basal growth from early or mid-summer onwards, depending on cultivar, with colours ranging from whites and soft pinks to saturated reds, purples and near blues; many have contrasting throats and neatly held buds.
