Geranium spp. and Pelargonium spp.

Cranesbills (Geranium) are herbaceous perennials known for their palmate leaves and saucer-shaped flowers in shades of pink, purple, blue, and white. They form mounds or clumps and are valued for their long bloom time and ease of care in gardens. Pelargoniums, often mistakenly called geraniums, are tender perennials or shrubs with diverse flower shapes and colors, including red, orange, and yellow. They are popular bedding plants and container specimens, prized for their vibrant displays. Neither are naturally indoor plants and struggle to thrive indoors long-term.

Pulmonaria officinalis, commonly known as Lungwort, is a herbaceous perennial native to Europe. It's characterized by its distinctive spotted leaves, which are typically green with white or silver blotches. The plant forms a low-growing clump and produces clusters of small, bell-shaped flowers that change color from pink to blue as they mature. Lungwort is primarily grown as an ornamental plant in gardens for its attractive foliage and early spring blooms. It is NOT naturally an indoor plant and will struggle without proper conditions.

Cranesbill

Repotting Only if rootbound. Repot in spring. If aggressively spreading, consider dividing instead of repotting into a larger container.

Pruning Deadhead spent flowers regularly to encourage more blooms. Prune back leggy growth in spring.

Fertilizing Balanced liquid fertilizer (10-10-10) diluted to half strength, every 4-6 weeks during the growing season (spring and summer).

Seasonal Care Spring: Fertilize and prune. Summer: Water regularly and deadhead spent flowers. Fall: Divide established clumps. Winter: Reduce watering and provide protection from frost if outdoors; provide supplemental light if overwintering indoors.

Lungwort

Repotting Not suitable for long-term container growing indoors. If attempted, repot every 1-2 years, or more frequently if root-bound, using a slightly larger pot.

Pruning Remove dead or damaged leaves regularly. Cut back after flowering to encourage new growth.

Fertilizing Balanced liquid fertilizer diluted to half strength, applied in early spring and again in late spring.

Seasonal Care In spring, fertilize and remove dead foliage. In summer, provide shade and consistent moisture. In fall, divide plants if needed. In winter, provide a layer of mulch for protection.
