Category: Seminum | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Aquilegia vulgaris Mix

Family: (Ranunculaceae)

(P) to 3′. Columbine. Europe. The common name Columbine is derived from the Latin word for “dove” in reference to the resemblance of the inverted flower to five doves clustered together – a most descriptive image indeed. The intricate flowers can be nodding or horizontal and consist of five sepals and five petals to 1-½ inches long and come in a wide variety of colours, often developing dorsal hooked spurs. Interesting five, fused seed follicles follow. Each follicle has a long thin beak and holds many small, shiny, black seeds and persists until fall. The bushy, clump-forming plants have branched, thinly hairy stems and pinnate leaves, with the basal leaflets trifoliate. One of the most beloved plants appearing in an array of colours, sizes and forms, thanks to natural hybridization in the garden.  In 2024 we collected from plants described below.  Perhaps you will get an even more exciting variant.  Sun to part shade.  4 & T2

Scientific Name (Genus/Species): Platycodon grandiflorus 'Perlmutterschale'

Family: (Campanulaceae)

(P) to 3′.  Mother of Pearl Balloon Flower. A lovely, delicate pale pink version of the above with spidery, dark pink veins.  Blooms from mid-summer and into the autumn when flowers are dead-headed.  Sun.  4 & T2

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Datisca cannabina

Family: (Datiscaceae)

(P) to 7′. False Hemp. An imposing herbaceous plant from India with graceful arching stems and finely divided foliage. A midsummer bloomer with ornamental tassel-like yellow flowers in racemes. This herb yields a yellow dye often used for silks. We have enjoyed it in a pot and now love it in the garden. Sun. 3 & T2

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Amsonia ciliata

Family: (Apocynaceae)

(P) to 20″. Narrow-Leaved Bluestar. This native of open sandy woodland and prairies from North Carolina to Missouri resembles a petite, more refined version of the Arkansas Bluestar (Amsonia hubrichtii) with five-petalled, starry, periwinkle-blue flowers in early summer. The narrow, almost needle-like foliage turns a brilliant golden yellow in the fall. Dry, well-drained soil. Sun. 3 & 7 for 12 weeks, then T2

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Amsonia rigida

Family: (Apocynaceae)

(P) to 2′. Stiff Bluestar. Southern Georgia and Northern Florida. A smaller Amsonia with a distinctive, dark reddish purple colouration to its emerging stems contrasting beautifully with the shiny, leathery, elliptical leaves. Loose cymes of light blue, starry flowers. The outer flower tube is flushed a darker hue giving it more pizzazz. Surprisingly hardy given its southern origin. Moist, well drained sandy soil. Sun/partial shade. 3, 7 for 4 weeks, then T2

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Angelica polymorpha

Family: (Apiaceae)

(P) to 6′. China. Exquisite, airy umbels of small, creamy white flowers and attractive lobed leaves. The flowering umbels look like a perfect firework display. A choice plant. Sun. 3 & 6

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Cephalaria gigantea

Family: (Caprifoliaceae)

(P) to 6′. Giant Yellow Scabious. Caucasus to Siberia. Magnificent clumps of distinctive foliage, divided into oblong spear-shaped leaflets producing tall, wiry branching stems ending in masses of delightful primrose-yellow pincushion blooms. Blooms July to August. Moist, well-drained soil. Sun. 3 & T2 & Δ

*Tip: If germination does not occur after 3-4 weeks, place seed pans in a cool location (about 40°) for 2-4 weeks

Category: Seminum | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Dipsacus laciniatus

Family: (Caprifoliaceae)

(B/P) to 7′. Cut-Leaved Teasel. Europe and Asia. Large, spear-shaped leaves with distinctive pinnately lobed edges, prominent white midribs and prickly stems. Pale green, oval porcupine-esque heads with intermittent rings of pale pink, individual florets. Invaluable in dried arrangements. Loves to self-sow and is perfect for the wild garden. Sun. 3 & T1

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Echinops tjanschanicus

Family: (Asteraceae)

(P) to 5′.  A tall, imposing Globe Thistle from Kazakhstan and the mountains of Central Asia.  A vigorous, erect, clump-forming, architectural perennial with spiny, deeply-divided, grey-green leaves, white beneath, and rounded, thistle-like, violet-blue flowerheads in summer.  Both Echinops make great cut flowers.  Sun.  4 & T2

Category: Rarium | Sub-Category: Perennials for Sun

Scientific Name (Genus/Species): Helianthus mollis

Family: (Asteraceae)

(P) to 4′. Ashy Sunflower. Tallgrass prairie, Michigan to Ohio. The dense, soft hairs that cover the stems and clasping, broadly ovate leaves, give the whole plant an attractive, ashen grey appearance. The large individual blooms are a rich buttercup yellow, appearing from midsummer into early autumn over open, somewhat wide and spreading clumps. A widespread and drought tolerant native for a wild garden or an informal planting. Sun. 3 & T3
