List 1

1.Astilboides tabularis

(http://www.whiteflowerfarm.com/24395-product.html)

Common name: shieldleaf rodgersia

family name: Saxifragaceae

Useful cultivars and selections:

USDA Hardiness Zone: 5-7

Mature height and spread:

height: 3-4feet

spread: 2-3feet

Form: low spread

Water use: medium

Soil requirements: Prefers moist, humusy, organically rich soils

Leaf arrangement: huge palm-like

Flower/Cone/Fruit description:Astilboides tabularis is noted for having large leaves somewhat resembling those ofRodgersia and upright flower spikes resembling those of Astilbe. It is valued by gardeners more for its unique foliage and architectural interest that for its flowers. Large, rounded, lobed, peltate leaves (to 2-3’ in diameter) on 2-3 foot tall petioles rising from the ground. Leaves have a shield-like appearance as reflected in the sometimes used common name of shield leaf. Leaves also have table-like surfaces, hence the species name. Tiny, astilbe-like white flowers form in panicles atop flowering stems that gracefully arch above the foliage in late spring.

Limitations:Watch for slugs. Foliage decline (leaves brown up) may occur in hot summers and/or periods of drought if soils are not kept moist or if plants are grown in too much sun.

suitable uses:Effective on pond or stream banks or landscape areas with consistently moist soils. May also be effective in woodland gardens and other moist but shaded areas.

 

2.Campanula latifolia

(http://www.bing.com/images/results.aspx?q=Campanula%20latifolia&FORM=BIRE&fdr=lc)

Mature height and spread:

height: 3-4 feet

spread: 1.5-2 feet

Form: cone

Water use: medium

Soil requirements: average, medium, well-drained soil

Flower/Cone/Fruit description:It is a clump-forming perennial that typically grows 3-4’ (less frequently to 5’) tall. Large, tubular, bell-like, purplish-blue flowers (to 2.5” long) appear in the upper leaf axils and in short terminal clusters (racemes) in early summer. Unbranched, hairy stems rise up from basal rosettes of ovate-oblong, toothed, stalked, hairy, medium green leaves (to 6” long). Leaves become smaller, narrower, pointed and eventually sessile as they go up the stems.

Limitations:Taller plants may need staking or other support. Can spread somewhat aggressively in the garden.

suitable uses:Best naturalized in open woodland areas, wild areas, cottage gardens or at the rear of borders. Group or mass for best effect. Considered somewhat coarse for a prominent location in the border.

List 2

1.Anchusa azurea

(https://anentangledbank.wordpress.com/2012/05/31/the-blues-anchusa-azurea-italian-bugloss/)

Common name: alkanet

family name: Boraginaceae

USDA Hardiness Zone: 3-8

Mature height and spread:

height: 1-3 m

spread: 1-1.5 m

Form: clump-forming

Water use: medium

Soil requirements: average, medium, well-drained soil

Leaf arrangement: opposite

Flower/Cone/Fruit description:a coarse, hairy, spring-blooming, clump-forming, short-lived perennial of the borage family that typically grows to 3-5’ tall. It is native to the Mediterranean but has been introduced in North America where it has escaped gardens and naturalized in British Columbia plus a number of States in the U.S. Alternate, entire, hispid, linear-elliptic to lanceolate leaves (to 6” long) are sessile or clasping at the base. Deep blue to violet flowers (to 3/4” diameter) are reminiscent of forget-me-nots (Myosotis). Flowers bloom in loose terminal spikes (scorpioid cymes) rising above the foliage in late spring to early summer.

Limitations:Crown rot can be a significant problem, particularly in wet, poorly drained soils. Taller plants usually need some kind of unobtrusive staking or support. Plant stems tend to open up and flop and foliage tends to depreciate in summer after bloom, particularly in hot and humid summer climates such as the St. Louis area.

suitable uses:Borders. Specimen or small groups. Naturalized areas.

 

2.Cephalaria gigantea

(http://www.esveld.nl/htmldiaen/c/cegiga.htm)

Common name: giant scabious

family name: Caprifoliaceae

USDA Hardiness Zone: 3-7

Mature height and spread:

height: 4-6 m

spread: 2-4 m

Form: clump-forming

Water use: medium

Soil requirements: average, medium, well-drained soil

Flower/Cone/Fruit description: It is an erect, clump-forming perennial that typically grows 4- 6’ (infrequently to 8’) tall. Scabiosa-like primrose yellow flowers (to 2.5” diameter) bloom in summer. Flowers appear singly atop stiff, wiry, branched, sparsely-leaved stems rising well above the foliage mound to 6’ tall. Pinnately-divided, dark green, basal leaves (to 16” long) with oblong to lance-shaped segments.

Limitations:Taller plants may need some staking or support.

suitable uses:This plant needs a large space. Border rears or cottage gardens. Naturalize in wildflower meadows or wild areas.

3.Lychnis coronaria

spread: 1-1.5 m

Form: clump-forming

Water use: medium

Soil requirements: average, medium, well-drained soil

Flower/Cone/Fruit description: Rose campion is a clump-forming perennial which is perhaps grown as much for its basal clumps of ovate, densely woolly, silver-gray leaves (to 5″ long) as for its 5-petaled, vivid rose magenta flowers (to 1″ diameter). Flowers bloom profusely on smaller-leafed, gray stems rising 2-3′ tall. Lengthy late spring to early summer bloom period.

suitable uses:Leaves and flowers provide excellent color and contrast to perennial borders, wild gardens, cottage gardens or meadows. May be used as an accent or specimen plant.

4.Lathyrus latifolius

Common name: perennial pea

family name: Fabaceae
