Aegopodium podagraria ‘Variegatum’ – I’ll be the first to admit that this is probably one of the most invasive plants in cultivation, but for contained areas in part to full shade it definitely fills in fast. Snow-on-the-Mountain or Bishop’s Weed has attractive compound foliage edged in cream and airy white flower umbels. Tolerates dry shade. Grows 12-18″ high by 2-3′ wide. Z2.
Lysimachia congestiflora ‘Midnight Sun’ – This newer compact cultivar of Moneywort is one of the Proven Winner Selections. It features deep bronze-purple foliage (with green veining showing through) and larger bright yellow flowers borne from May to August. Prefers part to full sun and is also useful as a trailer in containers. Grows 4-6″ high by 12-14″ wide. Hardy to zone 6.
Cymbalaria muralis (syn. Linaria cymbalaria) – Commonly known as Kenilworth Ivy, this evergreen perennial (semi-evergreen in colder climates) does not like foot traffic, but is useful for filling the cracks of natural rock walls. It bears rounded, lobed green leaves and intricate violet-blue snapdragon-like flowers. Part to full shade. Grows 2″ tall by 18″ wide. Hardy to zone 5.
Soleirolia soleirolii ‘Aurea’ (syn. Helxine soleirolii ‘Aurea’) – This bright gold cultivar of Baby Tears is useful in evenly moist soils in shaded rockeries. It bears small insignificant white flowers from May to June and is evergreen where hardy, but may go herbaceous in colder temperatures. A good choice for Fairy Gardens, as it can be grown indoors. Grows 1-2″ high by 6″. Z8.
Ajuga reptans ‘Purple Torch’ – A versatile evergreen perennial which forms a dense mat of rounded glossy deep green leaves that shift to bronze in winter. It produces showy lavender-pink flower spikes (up to 12″ tall) from April to June. Tolerant of moist soils and prefers a part to full sun exposure. Dislikes competition from tree roots. Grows 3-5″ high by 8-20″ wide. Hardy to zone 3.
