USDA Plant Hardiness Zone Map

Close

The most sought-after of all asarum species, from Aristolochiaceae family - related to Dutchman's pipe. This clumping species from China has large, 6", glossy, rounded arrowhead-shaped, green leaves. It is certainly best-known for its stunning flowers (often the subject of fine paintings). The 2" flower is velvet-black outside with a stunning white interior. This easy-to-grow species really responds well to rich humus-laden soils and high fertility. A well-grown 10" tall x 18" wide clump of Asarum maximum 'Green Panda' is simply stunning.

Green Panda is a perennial groundcover that has evergreen leaves. A great landscape plant for tucking into corners or planted in mass in the shade. It is a perfect container plant, great for indoor culture thanks to its shade tolerance.

The plant is cold tolerant.

Asarum splendens

Asarum splendens forms a clump of arrowhead-shaped leaves, dark green with handsome silver markings, similar to a Cyclamen.Deep purple-brown flowers hide among the leaves in spring. Evergreen in mild winter regions.

Pararistolochia goldieana

Pararistolochia goldieana is an unusual and eye-catching, fast-growing perennial vine or creeper native to Equatorial Africa, specifically Sierra Leone, Nigeria, Fernando Po and Cameroun. It is an evergreen, woody climber and can grow up to 30 ft high, climbing tall trees and adding an extra layer of vibrancy to the forest. With its glossy, heart-shaped leaves, it is a sight to behold. What is most remarkable, however, is its oversized, trumpet-like flowers which can reach up to 12 inches across, featuring mottled purple to red petals with a distinctive purplish striped throat. Pollinated by flies, their bizarre shape gives the plant its name of African Corpse Flower.

When it comes to cultivation, Pararistolochia goldieana prefers a sheltered, semi-shaded spot of the garden but can thrive in full sun if well-watered. Regular watering is key for this species to bloom abundantly and bless its admirers with its spectacular foliage and always surprising flower displays. It is important to note that while this plant thrives in temperatures above 55F, it won't tolerate frost and must be kept at least above freezing to ensure healthy growth. Grown in USDA Zone 10-11, this plant is perfect to be used as a climber to cover sun-drenched walls, espalier trees and cover sheds.

For those residing in colder regions, the plant can still be enjoyed by growing Pararistolochia goldieana in a large pot and protecting it with layers of straw during late autumn and winter. This way, it can be moved to a sheltered spot during colder months and be brought back to a sunny spot in the garden when temperatures rise. The same watering principles apply when grown in a pot and the additional care of wrapping the pot in bubble wrap during winter time is recommended.
