Sempervivum 'Cornelia'

Description Sempervivum 'Cornelia' Care Guide FAQ/Common Issues   Sempervivum 'Cornelia' is a frost hardy houseleek succulent from the alpine plant family, native to the mountainous regions of Europe where it grows in rocky, harsh conditions. It grows where other plants struggle, making it suitable for beginners and experienced growers alike.   Cornelia forms tight rosettes of thick, fleshy leaves with burgundy-red edges that contrast against green centers. The leaves have pointed tips and smooth texture, with each rosette reaching 3–4 inches across at maturity. It develops a clustering growth habit, creating colonies of offsets around the mother plant as it matures.   In summer, star-shaped flowers in shades of pink or white emerge on tall stalks above the rosettes. Cornelia handles dry heated air without stress and tolerates balcony wind and rain exceptionally well.   Cornelia works well in rock gardens, containers, and outdoor succulent displays. It needs rotating occasionally for even growth and handles drafty locations that challenge other houseplants. The plant is pet friendly, safe around cats and dogs. It grows outdoors in autumn and throughout winter in most climates.   Sempervivum 'Cornelia' grows well in partial sun to full sun, needing at least 4–6 hours of direct sunlight daily.   Water it deeply every 7–10 days during spring and summer, reducing to monthly watering in winter, allowing soil to dry completely between waterings.   Cornelia does best in well-draining soil with added perlite, sand, or pumice for optimal drainage.   It handles temperatures from 20°F to 80°F and survives harsh frosts down to -30°F.   Cornelia grows slowly and rarely needs fertilizer, producing offsets naturally throughout the growing season.   It is hardy in USDA zones 3–9 and tolerates temperatures down to -30°F. It grows outdoors year-round across Alaska, Maine, Vermont, New Hampshire, Montana, North Dakota, Minnesota, Wisconsin, Michigan, New York, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Missouri, Nebraska, Colorado, Wyoming, Idaho, Washington, and Oregon.
