What Makes Potentilla So Special?

Potentilla is special for its long bloom time, often flowering from late spring through fall, and its cheerful, five-petaled flowers that resemble small, wild roses. They are generally tough, adaptable plants that are easy to grow and require little maintenance. The sheer abundance of flowers over a long period, combined with their ease of care, makes them a popular choice for many gardens. Different species offer a variety of growth habits, from low-growing groundcovers to shrubby forms.

Description

• Growth Habit: Varies depending on the species. Some are low-growing and spreading, forming mats or clumps, while others are upright and shrubby.
• Height: Ranges from a few inches to several feet tall, depending on the species.
• Foliage: Leaves are usually palmately compound (divided into leaflets radiating from a central point, like a hand), often with 3-7 leaflets. The foliage is usually green, but some species have silvery or gray-green foliage.
• Flowers: Five-petaled flowers that resemble small, single roses. Colors range from yellow, white, and pink to orange and red.

Details Gardeners Care About

• Sunlight: Full sun is best for most species, although some can tolerate a little bit of light shade.
• Soil: Well-drained soil is essential. They tolerate a wide range of soil types, including poor, dry, sandy, or rocky soils.
• Water: Drought-tolerant once established. Water regularly when young but then reduce watering.
• Hardiness: Varies depending on the species. Many are hardy in USDA zones 3-8, but some are more cold-sensitive.
• Deer Resistance: Generally considered deer-resistant.
• Attracts Pollinators: The flowers attract bees, butterflies, and other pollinators.

Native Habitat Potentilla species are found worldwide, primarily in:

• Temperate and subarctic regions of the Northern Hemisphere

They are often found in:

• Meadows
• Grasslands
• Open woodlands
• Rocky slopes
• Alpine areas

Landscaping Design Tips

• Borders: Suitable for the front or middle of the border, depending on the species.
• Rock Gardens: The low-growing, spreading species are excellent for rock gardens.
• Groundcover: Some species can be used as a groundcover.
• Cottage Gardens: Their cheerful flowers and informal habit make them a good fit for cottage gardens.
• Shrub Borders: Shrubby species can be used in shrub borders or as informal hedges.
• Containers: Some of the smaller species can be grown in containers.
• Mass Planting: Works well

Planting and Care

• Planting Time: Spring or fall.
• Spacing: Space plants according to their expected mature size.
• Planting Depth: Plant at the same depth they were growing in their nursery pots.
• Watering: Water thoroughly after planting and keep the soil moderately moist until established. Then, reduce watering.
• Mulching: Mulch can help retain moisture and suppress weeds, but it is not essential.
• Fertilizing: Generally, does not need much fertilizer. A light application of compost or a balanced fertilizer in spring can be beneficial.
• Deadheading: Deadheading (removing spent flowers) can encourage continued blooming and prevent self-seeding (if desired).
• Pruning: Prune shrubby species in late winter or early spring to maintain shape and encourage bushier growth. Low-growing species can be sheared back after flowering.
• Division: Perennial species can be divided in spring or fall.

Potentilla neumanniana 'Nana' (also sometimes still sold under its older name, Potentilla verna 'Nana'), which is a dwarf cultivar of Spring Cinquefoil.

What Makes Potentilla neumanniana 'Nana' So Special?

'Nana' takes the best qualities of Spring Cinquefoil – its cheerful yellow flowers, long bloom time, and ease of care – and packs them into a tiny, compact package. It is special for being an exceptionally low-growing, mat-forming groundcover that is perfect for small spaces, rock gardens, and edging. It is a tough little plant that provides a bright splash of color in spring and early summer, with attractive foliage the rest of the year.

Description

• Growth Habit: Very low-growing, mat-forming, spreading perennial. Forms a dense carpet of foliage.
• Height: Only 2-4 inches tall, spreading to about 12 inches wide (or more over time).
• Foliage: Small, palmately compound leaves with 3-5 leaflets (sometimes more). The leaflets are toothed and a medium green color. The foliage is semi-evergreen to evergreen in milder climates.
• Flowers: Bright yellow, five-petaled flowers, about ½ inch across, that appear in spring and early summer. They are held just above the foliage.

Details Gardeners Care About

• Sunlight: Full sun is best for optimal flowering. It can tolerate a little bit of light shade, but flowering will be reduced.
• Soil: Well-drained soil is essential. It tolerates a wide range of soil types, including poor, dry, sandy, or rocky soils. It does not like wet, soggy soil.
• Water: Drought-tolerant once established. Water regularly when young but then reduce watering.
• Hardiness: Hardy in USDA zones 4-8.
• Deer Resistance: Generally considered deer-resistant.
• Attracts Pollinators: The flowers attract small bees and other pollinators.

Native Habitat

Potentilla neumanniana is native to:

• Europe

It is typically found in:

• Dry grasslands
• Rocky slopes
• Alpine meadows

Landscaping Design Tips

• Rock Gardens: An ideal choice for rock gardens, where it can spill over rocks and fill in crevices.
• Edging: Perfect for edging paths, walkways, or borders.
• Groundcover: A great groundcover for small, sunny, well-drained areas.
• Between Stepping Stones: Plant it between stepping stones for a charming effect.

Planting and Care

• Planting Time: Spring or fall.
• Spacing: Space plants 8-12 inches apart.
• Planting Depth: Plant at the same depth they were growing in their nursery pots.
• Watering: Water thoroughly after planting and keep the soil moderately moist until established. Then, reduce watering significantly.
• Mulching: Mulch can help retain moisture and suppress weeds, but it is not essential. Avoid burying the crown of the plant.
• Fertilizing: Generally, does not need fertilizer.
• Shearing: Shear back the plants lightly after flowering to encourage denser growth and remove spent flowers. This is optional, but it helps maintain a tidy appearance.
• Division: Can be divided in spring or fall if desired, but it is not usually necessary.

Taxonomy (Simplified)

• Genus: Potentilla
• Species: neumanniana
• Cultivar: 'Nana'
• Family: Rosaceae (Rose family)

Morphology (Simplified)

• Stems: Creeping, prostrate stems that root where they touch the soil.
• Leaves: Small, palmately compound, with 3-5 (or more) toothed leaflets.
