The appeal of Alchemilla or Lady's Mantle lies in the join of the leaf to petiole. Raindrops or dew collect there and look almost like a drop of mercury. Add its shade tolerance, moist soil tolerant and the pleasant shade of green with the cloud of yellow flowers and you have a perennial that has been in gardens for many years. Since the plant breeders keep working to find better plants, 'Thriller' is a little sturdier than the species. Plant may reach 24"/60cm tall.
Please note: This picture shows what the plant may look like when more mature. At this time our plants may not look like this.
