Well, it almost feels like summer has arrived in Norfolk - if you ignore the threat of frost earlier in the week, and the cold wind today!  I've cut my first annual bloom - a gorgeous little Lupin called 'Snow Pixie'. The buds on my annuals are just waiting to open. Once they do, I will be cutting flowers from now until the first frosts. However, it will be a week or so until the annuals are fully up to speed and appearing en-masse in my vases. In the meantime, there are plenty of flowering perennials to pick.

June flowers
June Flowers - Red Campion, Heuchera, Astrantia, Scabious, Ox-eye Daisies, Borage, Rosemary and Roses.

I've revamped my mixed borders this year to expand the number of perennials that produce cut flowers, while maximising year-round interest. When picking perennial flowers, unless you have the space for a dedicated perennial cutting bed where you can treat the plants as a flower crop (which I don't), then you will need to be picking flowers here and there from plants to ensure that you still have a good display outside.

Most perennials, like Knautia macedonica, benefit from dead-heading so the action of cutting flowers will stimulate more to appear. I have three Knautias that produce so many flowers that I can pick plenty of flowers from them without stripping them of flowers. I find that some perennials, like Astrantia, are slow to replace cut flowers. I will only snip a few flower stems on such plants so that there are still flowers for the garden. Just 3-5 stems of a few perennials, supplemented with foliage from shrubs and perhaps some herbs will create a lovely vase-full. The key is to grow more than one of each type of perennial. Planting in loose groups of 3 or 5 also looks very natural in a border and creates a sense of repetition and balance.

Astrantia 'Hadspen Blood'
Astrantia 'Ruby Wedding'

Here are a selection of my favourite perennials for June:

Astrantia, Masterwort or Hattie's Pincushion. The flowers of Astrantia are unusual in that they are formed by a group of tightly packed florets, backed by petal-like bracts. They flower from June to August and have serrated, dark green leaves. I have a pinky-red variety called 'Ruby Wedding' and 'Alba', a white form. They grow well in either full sun or partial shade. This is  a long-lasting flower once cut and also lasts well out of water so would make a good addition to the buttonholes if you are thinking of growing your own wedding flowers.

Cottage garden favourite Alchemilla mollis
Alchemilla mollis with water droplets

Alchemilla mollis, Lady's Mantle. This wonderful plant has scalloped, bright green leaves which catch droplets of rain water. From June to September, it produces a frothy haze of tiny, chartreuse yellow flowers. It is ideal edging paths. Superb for foliage and as a filler in arrangements. I have a few patches throughout the garden, in both sun and shade. The shady ones will flower later in the season which is handy to prolong the cutting period.

Leucanthemum vulgare, Ox-eye Daisy. I really should have included this in a previous article about flowers to cut in May as I have been cutting them for about a month now. They are lovely large daisy flowers and add a meadow-like, informal feel to a jug of flowers. They are our largest native species of daisy and are commonly seen on road-side verges. A campaign run by Plantlife is trying to protect rural road verges which are a vital refuge for wild flowers driven out of our farmland.

Knautia macedonica. Dark crimson, pincushion-like flowers are borne on long, wiry stems. This tall perennial is great for the back of a border and just keeps flowering all through the summer. The more you cut the flowers, the more flowers will form, making it the perfect perennial for a cutting garden.

Knautia macedonia
Knautia macedonica

Dianthus carthusianorum, Carthusian pink. Good for growing in pots. This is a tall pink with small, single, magenta flowers above narrow, grassy green foliage. Deadheading / picking flowers regularly will help encourage more flowers.

Silene dioica, Red Campion. This perennial has carmine-pink flowers and is often seen growing along roads and hedges. It's an important plant for wildlife, its nectar attracts hoverflies, butterflies and long-tongued bumble-bees. It responds well to picking and flowers abundantly and its bright flowers really liven up a flower display.

Scabiosa caucasica, Pincushion Flower. I grow annual Scabious too, but flowering before then is my lovely pale purple, perennial Scabious. The more flowers you pick, the more will come. I grow this in a pot but it would be equally good in a border.

Huechera, Alum root or Coral bells.  I love Heucheras as they come in a range of foliage colours, tolerate sun and shade and I find that they are pretty much evergreen in my garden. The leaves start to look a bit tired by February so I cut them down and they spring back up with fresh growth. They produce tall, slender flower spikes with bell-shaped flowers, hence the common name, Coral bells.

Other perennials flowering in June: Lupins, Osteospermum, Peonies and Valerian.

A taster of which plants you could be cutting this month from your garden. It is possible to design your beds and borders to include a plethora of flowers for cutting without affecting the display in the garden. All the plants make great garden plants in their own right. Just a few flowers of each type make a lovely arrangement and many of the plants are also brilliant for wildlife.

Tulips
I have Tulips scattered throughout my garden beds but just pick a few stems here and there (in addition to a dedicated raised bed which I treat as a crop). Plant double what you need in the border and you will have extra flowers to cut for indoors as well as a great display in your beds.
If you choose a mix of early, mid and late flowering forms, you can harvest flowers from March to May. Tulips flower best in their first year but you can select varieties that are better at repeat-flowering than others. I've grown Purissima, a white form which flowers in mid-Spring which is just starting to go over, Queen of Night (very dark purple) which started to flower towards the end of April and is looking great in May, 'Negrita' a lighter purple looking good in early April and Black parrot with it's dark colour and lovely frilly edge flowering in late Spring which is still looking good. All of these are supposed to be good repeat flowerers, although as this is their first year, I will have to report back next Spring.

Alliums
We planted over a hundred Allium bulbs the Autumn before last and it has really transformed our beds in May and June before most of the perennials come into flower and after most of the Tulips have done their thing . As there are so many, I can pick a few at a time for cutting without much impact on the garden. I have a mix of A. 'Purple Sensation' with its large, rounded purple pom-pom head, A. 'Cristophii' which has large, fire-work heads of star-shaped, purple flowers, A. Nigrum - a lovely white form and lots of the smaller, round-headed A. sphaerocephalon which flower later in July.

Forget me nots
These started flowering in early April but are still popping up and looking good, especially on the shady side of the garden when flowers appear slightly later. They are wonderful flowers for mixed Spring posies.

Aquilegias
Lovely Spring flowers which come in range of colours and forms. I have a mix of dark purples and pinks dug up from my mother-in-law's garden. They self-seed and you will find lots of little seedlings throughout the garden which are easy to either weed out or transplant to where you'd like them.

Euphorbia
A great foliage plant and a lovely zingy, acid green which looks good with dark Tulips and with colourful Spring flowers. There are many different forms of Euphorbia, both annual and perennial. I grow Euphorbia amygdaloides v. robbiae which is an evergreen perennial. It looks great in my border year-round and is invaluable as it thrives in partial and full shade.

Bluebells
A classic native British flower which thrives in shade. I inherited a small clump growing around the base of a Silver birch in my garden. A few flower spikes cut just as the bottom flowers are emerging adds a lovely dimension to a Spring flower display. You should never cut Bluebells growing in the wild but do go and visit a bluebell wood in May for a spectacular display. If you do add Bluebells to your garden, ensure you plant our native Bluebell rather than the Spanishone as our native species is under threat.

Viburnum lantana (Wayfaring tree) and Viburnum opulus (Guelder Rose)
These both flower this month and are useful shrubs with wonderful creamy-white flowers. I have both growing as part of a mixed native hedge.  A hedge is a great source of both foliage and flowers for arrangements if you don't have much room to grow shrubs in your beds. Both species will produce red berries in Autumn which are useful for adding colour to Christmas wreaths or Winter vases.

Guelder Rose
Viburnum oplus (Guelder Rose) with its gorgeous flat clusters of flowers.


Erysimum 'Bowle's Mauve'

We have this perennial wallflower in a raised bed near the house and it flowers off and on all year round with perfumed mid-purple flower spikes which swarm with bees and butterflies in the Summer. They are one of the very best nectar supplies for insects as they have such a long flowering period so everyone should grow one for the bees and snip a few flowers for yourself too. Just 3-5 stems in a vase will add a pop of vivid colour.

Erysimum and Alliums

Lemon balm
This is a wonderful perennial herb. It smells divine, makes a yummy herbal tea and it has lovely fresh green foliage in May. The new growth is a bit soft and sappy at this time of year but if you sear the stems it will last quite nicely.

May garden flowers
Euphorbia, V. opulus, Hesperis, Alliums & Irises

Sweet rocket (Hesperis matronalis)
A biennial which, if you sow seed in late Summer and plant out in September, will be flowering now. Comes in purple or white forms and flowers profusely. It will self-seed which is great if you want a lot of it, otherwise, keep cutting the flowers and it won't ever get to the seed stage.
