Virtues: We love ‘Chumbyi’ silky rock jasmine (Androsace sarmentosa ‘Chumbyi’) for its fuzzy foliage and fragrant pink flowers. This semi-evergreen miniature perennial is perfect for a rock garden, stone-wall planting or year-round containers dedicated to other alpine plants, such as a hypertufa trough. Recommended by Colorado’s Plant Select Petites program in 2015.
