Alan Gray recommends the early-flowering climber Tropaeolum tuberosum ‘Ken Aslet’ for adding late-season interest to shrubs, noting its distinctive orange flowers and advising gardeners to lift and overwinter its edible tubers before frost. He also describes Tropaeolum smithii, a self-seeding climber with unusual leaves and yellow-and-red flowers, and suggests experimenting with sowing its seeds in sheltered outdoor trays.
