Phyteuma spp.
rampion
Overview
Phyteuma spp. is a genus of about two dozen perennial herbs in the bellflower family Campanulaceae, native mainly to the mountains and meadows of Europe and adjacent western Asia. Plants grow from a fleshy rootstock as a basal rosette of long-stalked, toothed leaves, sending up unbranched stems 4-32 inches (10-80 cm) tall depending on species. The small flowers are crowded into dense rounded heads or cylindrical spikes; each flower is narrowly tubular and strongly curved before opening, splitting into slender lobes that give the heads a bristly outline. Flower color ranges from deep blue and violet in Phyteuma orbiculare and P. scheuchzeri to creamy white in P. spicatum. Bloom comes in late spring and summer, followed by small capsules releasing many seeds. The genus grows in alpine and subalpine grassland, rocky slopes, and open woodland on moist but well-drained soils. Phyteuma spp. needs cool conditions and resents hot, humid summers and waterlogged winter soils, which shorten its life in lowland gardens and confine it mainly to rock gardens and cool borders.
Native Range
Phyteuma spp. is native to Europe and parts of western Asia, with its greatest diversity in the Alps, Pyrenees, and other European mountain ranges. It grows in mountain meadows, grassy slopes, rocky ground, and open woodland.Suggested Uses
Used in rock gardens, alpine troughs, gravel beds, and cool mixed borders. Combines with other mountain perennials and grasses in naturalistic and wildlife plantings for pollinating insects.How to Identify

Bloom Information
Flowering occurs from late spring into summer, roughly May through July, with each dense head lasting one to two weeks and rosettes producing one to several stems. Cooler mountain sites flower later in the season. Dry capsules follow and shed many small seeds.

Care & Maintenance
Care Guide
Grow Phyteuma spp. in full sun to light shade on moist, gritty, well-drained soil in a cool position that matches its mountain origins. It needs steady moisture during growth but sharp drainage in winter, as standing wet kills the fleshy roots. Plants resent prolonged heat and humidity, growing most strongly in cool-summer climates or on north and east aspects. Propagation is by seed or careful division of the crown in spring. A gritty mulch keeps the root zone cool and conserves moisture, and feeding is rarely needed on reasonable soils. Slugs can damage the young rosettes in spring.Pruning
Remove spent flower stems after bloom to tidy the plant and limit self-seeding, or leave some to ripen seed. Cut back dying foliage in autumn as the plant enters dormancy. No other pruning is needed.Container Growing
