Geum rivale 'Lemon Drops'

Water Avens

10365771514167|Geum rivale 'Lemon Drops'|Water Avens|

A yellow-flowered selection of water avens with nodding bell-shaped blooms. The lemon-yellow colour provides cheerful spring interest. Prefers moisture-retentive soil like other water avens. The nodding habit gives it graceful character.

Thrives in moist sites including stream banks and bog gardens. The yellow flowers combine well with blue spring bulbs and early perennials. More tolerant of wet conditions than most geums. The common name water avens indicates its moisture preferences. Suitable for moist woodland gardens.

Geum rivale 'Leonard's Variety'

Geum rivale 'Leonard's Variety'

Water Avens

10365771546935|Geum rivale 'Leonard's Variety'|Water Avens|

With so many yellows and blues around early in the year, this pink-red selection is a real pleaser, making lovely combinations without being brash. As a bonus, one can often expect a second flowering in August or September, especially after shears take it down to ground in mid-June.

Prefers moisture-retentive soil. The soft pink-red colour provides gentle tones for spring borders. The potential for rebloom extends the season significantly. Combines well with early bulbs and emerging perennials. The nodding flowers are characteristic of water avens species.

Geum triflorum

Geum triflorum

Prairie Smoke

10365771579703|Geum triflorum|Prairie Smoke|

Some know this native species by the name prairie smoke, referring to the superb long-plumed seed heads that appear shortly after inconspicuous flowers fade. En masse, these create a silver haze across meadows. The seed heads are the main ornamental feature.

Best situated in well-draining soil. Native across North America in prairies and dry meadows. The common name perfectly describes the misty seed head effect. The flowers themselves are modest but the seed display is exceptional. Suitable for rock gardens, prairie plantings, and well-drained borders.
