Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Saxifraga x apiculata

Family: (Saxifragaceae)

(P) to 4”.  The earliest plant to bloom outside at Stonecrop and a welcome sight it is, too.  Tight cushions of bright green, closely packed, narrow leaves are studded with an abundance of Primrose yellow flowers.  Sun.  4 & 7

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Campanula carpatica Mix

Family: (Campanulaceae)

(P) to 8″.  Tussock Bellflower.  Carpathian Mountains.  This seed is a lovely mix of blue, white and purple colours yielding large, solitary, five-petalled, up-facing, bell-shaped flowers.  Most welcome, as it flowers when other Campanula blooms are over.  A long bloomer but deadhead to keep the show going.  Sun.  4 & T2

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Erysimum helveticum

Family: (Brassicaceae)

(P) to 6″.  Mountain Wallflower.  C & E Europe.  Tufted clumps of linear, dark grey-green leaves are a great foil to the flat heads of purple tinted buds which open to clusters of fragrant, bright yellow, four-petalled flowers.   A beautiful alpine and extremely long-blooming, from spring well into the summer months.  Sun.  3 & T1

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Scabiosa ochroleuca

Family: (Caprifoliaceae)

(P) to 2′.  Cream Pincushion Flower.  Europe, West Asia.  Dainty, soft yellow, pincushion-like flowers.   A delightful plant whether grown alone or in the company of pastels.  Foliage is dissected and glaucous green.  Blooms from midsummer to frost.  A carefree plant preferring leaner soils and full 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: Rarium | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Edraianthus graminifolius

Family: (Campanulaceae)

(P) to 4″.  Grassybells.   Southeastern Europe.  This low-growing Campanula relative forms a cushion of narrow, grass-like foliage from which emerge short stems bearing many terminal clusters of upward facing, five-petalled, violet-blue bells. Thrives in lean gritty soil and tight rocky spaces and has proven to be reliably cold hardy for us.  Blooms May through June.  Sun.  4 & T2

This seed is either sold out or unavailable

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Geum triflorum

Family: Rosaceae

(P) to 16″.  Prairie Smoke.  North America.  A wonderful choice for the native garden or rock garden, this Geum has distinct, light red, globular, drooping flowers with styles that elongate and collectively begin to resemble a hair blowing in the wind.  Rosette-forming habit, with dissected dark green foliage.  A slow growing but fantastic groundcover. Unusual and unique.  3 & T2

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Sedum fosterianum subsp. elegans

Family: Crassulaceae

(P) to 8″. Stonecrop. NW and SW Europe. Lovely hardy sedum with blue-green, needle-like foliage. Prolific midsummer bloomer with attractive corymbs of star-shaped, yellow flowers and persisting attractive flat seedheads. Perfect for the sunny rock garden.  4 & T1

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Schivereckia doefleri (syn. Draba doerfleri)

Family: (Brassicaceae)

(P) to 6”.  Eastern Europe. A tough and attractive dwarf cushion with grey-green loose rosettes of oblanceolate, slightly toothed leaves. Four-petalled white flowers in terminal racemes of up to fifteen in late spring.  Long-lasting, buff-coloured seedheads follow.  Sun.  3 & T1

Category: Seminum | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Aethionema schistosum

Family: (Brassicaceae)

(P) to 6″.  Turkish Stonecress.  Turkey and Lebanon.  Erect, woody stems with narrow, blue-green foliage produce rounded heads of rosy lilac, four-petalled flowers in early summer.  Interesting multi-coloured, flat seed capsules follow and persist.  A welcome self-sower.  Sun.  3 & T1

Category: Rarium | Sub-Category: Alpine and Rock Garden

Scientific Name (Genus/Species): Campanula rigidipila

Family: (Campanulaceae)

(P) to 12″.  This rare plant is the world’s most southerly occurring Campanula from Ethiopia and the Kenyan highlands.  From a clump of thick, triangular, hairy, grey-green leaves, arise strong, erect stems carrying pale buds that open to lovely, clear blue bells with flared tips edged with white hairs.  Summer-blooming.  Sun.  4 & T2
