Eventual height & spread

Hoping they bulk up soon


Tiny plants arrived. Seemed a bit expensive for the size. All healthy though so hoping they put on some growth this year.



I would buy this again


Geranium Rozanne copes very well with our exposed garden in the Pennines and gives a long season of colour.


Yorkshire Dales


Highly recommended


The plant quickly established when repotted immediately after receipt. Lovely blue flowers throughout the summer until November, 2016. Looking forward to seeing it next summer. Will probably buy another.

Stunning colour


Geraniums are a must for sunny borders. I believe these very pretty flowers spread over time. They flowered well into November.

A winner...


This geranium was recommended to me by a professional gardener acquaintance and it hasn't disappointed. Long flowering and bigger than average flowers, it is fiiiling a gap at the front of a herbaceous border

I confidently recommend this plant.


Extremely versatile, reliable plant. I've grown Geranium Rozanne since it first appeared on the market and now have several clumps in various areas of my garden: herbaceous borders and even trailing down a dry stone wall. It's most prolific in part shade and where the soil is slightly damp. Once trimmed, after its first flush, the regrowth often flowers for many months. It sprawls but I like that. My recent purchase from Crocus was a birthday gift for a friend who had admired it several times in my garden.

Good ground cover


Grew well flourishing in my garden

Super Geranium


Planted near patio. Already formed an attractive plant in its first season and had many flowers throughout the summer. Would definitely recommend.




What a fantastic little plant this is!


I currently have three of these spread around different parts of my garden. I have come back today to order more. At the moment my plants are in the earth, but I also think this little plant would be terrific in a planter - time will tell. One of the greatest things for me, is that this is not understimated in its praise. I planted my plants early last year, they were still in full bloom into November, indeed, some of the last colour in my garden - I've fallen in love with this plant. I see it as a good all round plant. You are in for a treat if you buy these - it is no wonder it has an award of the centenery.

I planted geranium rozanne last year and they were wonderfully floriforous, masses of flowers for months. This year, though, they are mostly foliage and very few flowers. What am I doing wrong?


Hello, My 'Rozannes' are not doing as well this year either, but I put this down to the fact that I did not apply any organic matter around them in spring, and they have often had to make do without water for long periods (and it has been dry!). The other reason your geranium may not be flowering as well is if the plants overhead have grown and are casting more shade as the geraniums will flower best in a sunny spot.


Plant advice for 2 new beds please Hello, I need some help to decide which plants to put into two new areas please:- 1: A semi-circle flash bed at the front of the house, size approx 2m x 0.80m and 0.80m deep. I thought about the 3 following options for a small tree/bush in the middle:- a) Magnolia soulangeana, but I was worried about the size that it could grow to and possible problems with roots etc . Will it stay small if the size of the container is used to restrict it? b) Witch Hazel (Hamamelis intermediana 'Diane'). Will it spread too much? I think this is very pretty. c) Corylus avellana 'contorta' Then I also need to think about ground cover plants to help suppress weeds. I am only interested in fully hardy, easy to look after plants, could be with some flowers or coloured leaves. 2:- A thin path between neighbours (approx 2m x 0.40). My idea is to plant bamboo. I would love a modern thin run of bamboo with ground cover. My worry is which bamboos to use. I love the yellow, like Phyllostychys aureocaulis (Golden Grove) but not sure if it is strong enough as it could be exposed to some wind. I bought from you a couple of years ago the Phyllostychys aureosulcata 'Spectabilis' which I planted in pots but it died this year. I see on your website some other bamboos but I don't like them as much as their canes seems less exposed and have a lot more foliage. But possibly these would be a better alternative... ...? For the ground cover I as thinking of Ophiopogen nigrescen. Do you think these plants will be suitable, or have you any other suggestions? Thank you for your help, Galia

Hello Galia, All of the taller shrubs you mentioned for the semi-circular bed will get quite large, but their growth will be restricted (both in height and spread) if they are kept in a pot where their roots are restricted. For groundcover you could opt for any of the following:- Bergenia Helleborus Heuchera Epimedium Geranium Erica As for the bamboos, even the most well behaved one (Fargesia murieliae) will spread to around 1.5m across so you should keep this in mind when planting it in such a confined space. Perhaps a better option would be one of our hedging plants, which can be cut back hard against the wall. Taxus or Ligustrum would be good options. I hope this helps. Helen Plant Doctor

Crocus Helpdesk

Is it still ok to be cutting back herbaceous perennials, Lavender and Caryopteris late in the year? Dear Crocus, I didn't have time to cut back to ground level all my herbaceous perennial plants and some shrubs in the autumn, due to work and family commitments. It's difficult to get out into the garden just now as I only have a little time at the weekend. Would it be too late for me to cut everything back still between now in December and the end of February e.g hardy Geraniums, Hostas,etc. and shrubs like Lavenders and Caryopteris? I really would appreciate your advice. Many thanks Pamela

Pamela Spiers

Hi Helen, Thank you for your helpful information. The snow made the decision for me, it has lain for 4 weeks now. Kind Regards Pamela

Pamela Spiers

Hello Pamela, You can do the herbaceous perennials anytime between now and spring, but the Caryopteris and Lavenders should be tackled in spring. I hope this helps. Helen Plant Doctor

Planting companions for roses

Early flowering roses tend to come in shades of white, pink or purple-pink and most forms of the biennial foxglove, Digitalis purpurea, have toning flowers in similar colours. These appear in rose time, but carry on after the first rose flush has finished
