(COBRA LILY) This is one of the easier of this genus to grow…an herbaceous perennial that emerges as late as May or even June. Erect 12-18” stems bordered on both sides by thrice-lobed wonga (18-24”) leaves and topped with summer pink pitchers with dramatic silver striping, later maturing to striking red seed pods. Does this sound like an alien? It looks like one! Very weird and cool…just give it a spot in rich garden soil and the same culture as hostas and epimedium (light shade, regular moisture) and amaze your friends! USDA Z5-7
Sweet Flag is not a true grass, but plants have a distinctive, grassy appearance. This selection forms a very low mound of narrow golden sword-shaped leaves, beautiful in a moist rock garden or beside a pool or stream. Flowers are green and insignificant. Spreads very slowly. Foliage remains evergreen in mild regions.
Many folks insist that there is a fragrance emanating for the unusual and only pink flowered Arisaema, but I've never detected any. Very large leaves on a 12" - 24" plant. As with all of the Arisaemas, full shade to part sun, good rich soil produce the best plants.
One of the most unique and largest-leafed cobra lilies, yet easy to grow. The flowers are pink with white stripes, the 3-lobed leaves can reach over in 2' diameter. Grows into sizable clumps over time and can be divided for sharing. Emerges very late; late May into June, but once it emerges, things go fast and the plant goes into leaf and bloom at the same time. Grows well in shade where summers are hot (90s +) but takes quite a bit of sun in cooler climates. Needs well drained soil and don't give extra water until they sprout. Medium-sized corms, 1"+ in diameter, suitable for a 4"/quart pot. They'll most likely bloom next year.
This pink-flowered cobra lily is one of the most desirable for ornamental purposes because of the unique colour of the spathe in a genus that consists mainly of variations of green, burgundy and white. Here the light pink spathe is striped with white. A. candidissimum is later to emerge than other species and is often not seen until May when the flowers emerge as the beautiful and sub-tropical tripartite foliage is unfurling. A beautiful species worth collecting!
Not so much like a cobra, the white "flowers" inspire more than their fair share of exclamations even though the floral display is a bit peek-a-boo among the leaves. The foliage is large and three-part, tolerant of more direct sun than other species but still requiring moist soil.
Blooms: spring-summer, white w/pink,brown,green/ large trifoliate, glossy foliage Zone 5-9. 24', China, part shade-shade, moist, well drained
A cobra lily that does well in sun to light shade, this from China sends up flowers stalks in late spring/early summer topped with a pink pitcher flower, sweetly fragrant and beautifully striped with white veins. Two huge, three-lobed leaves, up to 2 ft across, follow to open beside the exotic flowers. A must have plant! Easy in sun to light or dappled shade where soil is well-drained, even rocky, and somewhat dry. Offsets quickly when happy. Frost hardy in USDA zone 5.
Usually our last Arisaema to bloom which protects it from late frosts. Dreamy pink flowers with wide white stripes on 16 inch stems. Clump forming.
One of the most sought-after Jack-in-the-Pulpits with simple large leaves and the flowers of sweetly scented virginal white (which is in total contraposition with the suggestive floral appendages so espoused in the genus but lends further credence to the notion that good girls like bad boys).
The latest of the jack in the pulpits to emerge. The lovely pink flowers are borne in June followed by large glossy leaves.
