PAEONIA
About 33 species of perennials and shrubs distributed in Asia, Europe and northwestern North America. Compound or laciniate foliage and large bowl-shaped flowers in spring and early summer. Very few species Paeonia are found in North American gardens, except Paeonia officinalis and its many hybrids. These beautiful plants can become the treasures of your garde

It is always a good idea to sow Paeonia seed as early as possible from the freshest possible seed. See all our other paeonia listings from this seasons fresh harvest under the general paeonia category.

PANAX(GINSENG)Family: ARALIACEAE
A small genus of perennials with tuberous roots native to North America and Asia. Two species are native to north eastern North America. Roots of the native Chinese species (Panax ginseng) have been used medicinally in China for centuries. As demand for ginseng roots in China began to exceed supply, export of this American species to China began to occur. American ginseng has unfortunately become endangered or extinct in the wild due to over-harvesting of its roots. American ginseng is now sometimes commercially grown for export.

PANAX quinquefolius (Moist Packed) New Early Summer2511
American Ginseng30-45cm  Zone: 4
Native to eastern North America growing in fertile, damp well-drained soils in woods. The insignificant mildly-fragrant yellowish-green flowers appear in early summer over compound leaves. These are followed by red berries in late summer.

In 1988, ginseng was officially listed as "threatened" in Canada.

Our seed comes from garden grown plants and is in very limited quantities. Order early.
Germination Instructions: Seed has been moist packed since collection and requires cold treatment.

PANICUM(SWITCH GRASS)Family: GRAMINAE
Over 600 species found worldwide. In North America these were a major constituent of the tallgrass prairie. The varied forms and the beauty of these native grasses, long a staple of the German nursery trade, have taken longer to become appreciated in North America.

PANICUM virgatumAutumn2514
Switch Grass120-240cm  Zone: 3
One of North America's contributions to the international hit list of ornamental grasses. Grey-blue leaves and feathery masses of green to pink flowers.

PAULOWNIA(PRINCESS, FOXGLOVE TREE)Family: SCROPHULARIACEA
A genus of 17 deciduous trees native to east Asia with large, dramatic leaves and foxglove-like flowers in terminal panicles.

PAULOWNIA tomentosaSpring2563
9-10m  Zone: 6
The Foxglove Tree is well known for its showy groups of fragrant, pale violet or rich purple foxglove-like flowers that appear in spring, before the leaves emerge. The tree is symbolically connected to the Phoenix because of its ability to entirely regenerate from the root, even if lost to fire or other catastrophe. Because of this ability and the fact that the leaves are large and dramatic, gardeners can stool the plant and use it as a very dramatic accent in the garden. This we do here, even though the tree is not hardy for us, and the effect is wonderful. All growth is cut to the ground in spring and kept to a single shoot. This will be a "pseudo-trunk' a bamboo-like stem reaching 10-12' in a season, bearing the huge, handsome leaves (up to 3' across).
Germination Instructions: Easy, warm germinator.
20 seeds  $4.00

The stem and mid-rib of the foliage first turn purple after about eight leaves have developed. The foliage will turn dark purple when plants are moved from the greenhouse outside into full sun.

POLYSTICHUM(HOLLY FERNS)Family: DRYOPTERIDACEAE

POLYSTICHUM acrostichoides2807
Christmas Fern30-75cm  Zone: 3
One of the first ferns to send up fiddleheads in the spring. Covered with scruffy brown scales, they arise from the clump of last year's fronds flattened by winter's snow. The glossy, dark green leaves are more erect in summer, growing in dense, asymmetrical clumps. This is one of the best ferns for the woodland garden. It has elegant evergreen fronds, a neat pattern of growth, and is tolerant of deep shade; combining well with woodland shrubs and herbaceous perennials. If planted thickly, will serve as an attractive evergreen ground cover. Spores wild collected in Ontario.
Germination Instructions: Fern spore germination instructions will be provided.

POTENTILLA(CINQUEFOIL)Family: ROSACEAE
Large group of perennials, herbs and shrubs comprising 500 species, found throughout the northern temperate and frigid zones. Strawberry shaped leaves and elegant, 5-petalled rose-like flowers in white, pink, yellow, orange or red.
Potentillas need as much sun as you can give them and do best in poor, well-drained soils. In fact some seem happiest when baked and starved – too rich a soil they become very leggy with few flowers.

POTENTILLA fragiformisSummer2823
30cm  Zone: 4
Yes, yes, we know that P. fragiformis has ceased to exist as a valid species; having been swallowed up by P. megalantha. So, why are we listing it? According to the Flora Russica, these are still two distinct species; fragiformis being native to coastal areas of Chukotka and Kamchatka, Russia (and recently discovered in Alaska, to be added to their AKNHP list of rare plants for the state). Our seed comes from plants originally grown from wild collected Kamtchatka seed. Leaves are smaller and narrower than P. megalantha. The bright yellow flowers are also smaller, but more plentiful. The two also do not seem to hybridize. And that's the answer to the question.

PRIMULA(PRIMROSE)Family: PRIMULACEAE

PRIMULA incanaSummer2897
Mealy Primrose40cm  Zone: 2
Native to parts of central and western North America growing in alkaline clay soil in floodplains and moist open meadows. A heavily farinose species with a small rosette. Clear pale pink flowers in summer. Seed wild collected with our thanks by Cohan Fulford in Alberta.

From the Flora Of North America: Primula incana is usually heavily farinose, at least when young, and has relatively tall scapes and tight umbels of homostylous flowers. As with some species of the genus, anthesis often begins before the scape is fully elongated; plants at first are quite small, but elongate throughout anthesis and typically become relatively tall and lanky in age. This has led to confusion with other arctic species, especially P. stricta, which has considerably less farina, a shorter scape, and a more maritime distribution. In fruiting stage, P. incana has been confused with P. laurentiana, which has looser umbels throughout anthesis, larger flowers, and a more eastern distribution. Primula incana generally replaces P. laurentiana to the west and south of Hudson Bay. The single octoploid count for P. incana is questionable; the species appears to be consistently hexaploid in other counts.

PRUNUS tomentosaSpring2903
Nanking Cherry1.8-3m  Zone: 2
I was first introduced to Nanking Cherry by Hugh Skinner in 1998? as we tasted our way along a long hedge of them in Zone 2 Manitoba. And as I ate the delicious small fruit, I put each pit in the pocket of my coat, determined to grow them once I got home. Nanking Cherry is a compact shrub, native to northern China and Japan, which can also be grown as a small tree. It has beautiful pinkish-white flowers in spring. The dark green leaves break dormancy early, are retained even in drought and are slow to drop after the first killing frost. Fruit is a small, short-stemmed red cherry with a wonderful sweet taste. Its hardiness, rapid growth, dense, compact form, and excellent retention of leaves makes this species a desirable shrub for the northern garden.
Germination Instructions: Cold treatment required.
