How to grow Alchemilla mollis common name Lady's mantle

Dark red Cotinus with brigth green Alchemilla mollis

Alchemilla mollis, common name Lady's mantle, is an easy to grow herbaceous perennial, fully hardy which will grow successfully in many different conditions. Alchemilla prefers damp soil with some sun; it is vigorous plant which will survive most conditions.  This means it will tolerate semi shade, any aspect, exposed and sheltered spots which makes it a useful plant for awkward areas.  It will also grow in damp areas as long as they are not boggy. The most common variety on sale is A.mollis, a good variety with the RHS award of garden merit so always a safe bet when choosing a plant.

When it first comes into leaf and flower Alchemilla makes a love a mound of lime green foliage and which looks lovely with raindrops on it as seen in the mage. The leaves are almost downy in appearance and hold the water well.  Alchemilla mollis is one of those plants which does look good in the rain in common with Hosta.  

The flowers are formed on sprays, with multiple flower heads, and they start off when first emerging a strong lime green colour  which become a mass of tiny yellow flowers from early summer onwards. This variety grows to around 60cmc and makes good at the front of borders and as a fill in plant. 

Alchemilla mollis looks good with many plants,  especially good with Allium cristophii and the  lime green foliage looks good with purples and blues. One advantage of growing Alchemilla with Alliums, and why it's such a good companion plant for Alliums, is that often the leaves around the base of Allium look tatty even before the plant has flowered, it's one of it's shortcomings. Plant Alchemilla around the Alliums and it will cover the base leaves of the Allium.

Alchemilla also looks good as a contrast growing around the base of a Cotinus "Royal Purple", the strong lime green contrasts with the purple. The contrast is good but be aware a Cotinus is potentially a large shrub, 3 meters plus, although it can be kept in check by pruning.   Alchemilla also look good combined with the soft blue of Nepeta (Cat Mint) a nice mix of blues with lime green/yellow and both flowering in June.

 I have also seen Alchemilla planted to good effect growing at the base of a copper beech hedge and Alchemilla looks good along a path.

Down side to growing Alchemilla Mollis

One of the  down sides to growing Alchemilla is that it is a big self seeder which some gardeners may find a problem, and it can be a chore to weed out where you don't want itAlchemilla comes into leaf early in the year and so can look tired by July, with brown spots and fawn areas marring the foliage, as in the images below.

An easy solution is to take the shears to it; either a complete haircut, cut it partially in stages and new clean foliage will be up and sprouting within a couple of weeks maximum and look good for the rest of the growing season.  It will not flower again but it will produce fresh looking foliage. 

Just to illustrate how quickly it grows back and encourage the bold gardener in you. In the images below, the first shows the Alchemilla  if full bloom looking really good, and then some weeks later when the foliage and flowers are looking sad, a bit tired and brown.  I then cut it back and within a short period of time, about 2.5-3 weeks,  it had re grown some new fresh foliage as in the third image. 

Alchemilla mollis is a simple plant, which is why there is not much to say about it. It is easy to grow, unfussy about it's conditions and although a number are listed in the RHS Encyclopedia of plants, you really only see A. mollis for sale.
