Iris ensata ‘Rose Queen’
The Japanese water iris, which is still sometimes called Iris kaempferi, grows best in shallow water but likes it dry when it’s not in bloom. In its home country of Japan, where it comes from, pond levels are often changed throughout the year to make it happy.
That being said, it doesn’t have to be grown in water as long as the soil can hold water, and it looks best when it is growing near water. ‘Rose Queen’, with its distinctive flower colour, has smaller, more delicate flowers than many other ensatas.
AGM. Height 75-90cm. Origin Garden origin (species from Japan and the Far East). Conditions Rich, moist soil; full sun. Hardiness RHS H6, USDA 5a-8b. Season of interest Early summer.
The distinctive stripy pink spathes of this exotic-looking aroid make it one of the best arisaemas for flowering. It emerges from the ground as late as early June, and quickly produces flowers before the leaves appear. Once it has settled down, these three-leafed leaves can grow up to 45 cm across. At that point, it’s a very pretty late-summer foliage plant.
After the first frost in the fall, this show will be over. For the next seven or eight months, it will be below ground as round and flattened, fleshy tubers, so make sure you mark its spot well and cover it with a thick layer of mulch.
AGM. Height 30cm. Origin China. Conditions Warm spot in part shade. Hardiness RHS H4, USDA 5a-7b. Season of interest All summer.
This is a climbing rose with shiny green leaves and clusters of red flowers with a white center that bloom all summer and into fall. The flowers are followed by pretty orange hips.
Without using any chemicals, this rose has always given us clean leaves and lots of flowers for 40 years. It grows in a part of the country that gets a lot of rain, where most roses won’t last more than a year or two without being sprayed regularly. It’s painful to clean up and tie it in every year because it has thorns, but it’s so worth it.
AGM. Height 3m. Origin Garden origin. Conditions Moist but well-drained soil; full sun. Hardiness RHS H5, USDA 4a-10b. Season of interest All summer.
This Kniphofia is very different to most people’s vision of a red hot poker. Instead of a spike of flowers close together, this species has soft orange flowers that are spread out and curve down gracefully, more like an aloe. The way it grows is also different. Like the flowers, it doesn’t form a big clump. Instead, it spreads out slowly, making a colony of rosettes, each with a few leaves lying down.
Repeat flowering through the summer. One thing that might be bad about it is that it’s not quite as hardy as some
Height 60-90cm. Origin East Africa. Conditions Well-drained soil; full sun to light shade. Hardiness RHS H3, USDA 7a-10b. Season of interest Summer.
A bindweed that I actually love. It’s been more than 25 years since I first got a tiny root to live and grow. It was first seen on the island of Crete, where it covered tilled ground between olive groves and large, steep, sunny roadside verges. It was not until I managed to replicate those conditions did it deign to settle in and spread.
Now it grows underground and spreads its pretty silver leaves and clean pink flowers through a soft purple-blue catmint. It’s a beautiful sight that lasts for weeks.
Height Scrambling to 60cm. Origin Mediterranean. Conditions Well-drained soil; full sun. Hardiness RHS H3-4, USDA 6a-8b. Season of interest All summer.
Because some species of Eryngium grow naturally near the water, they are often called sea hollies. This is because their leaves are very sharp. But in a garden, all they need is a sunny, well-drained spot. For many weeks in the summer, they will grow their shocking, cone-shaped flowerheads surrounded by what look like poisonous bracts.
There are several cultivars of this hybrid, and the blue in the flowerheads and stems varies slightly between them. All of them are good, though. Easily propagated by root cuttings in late winter.
Height 60-90cm. Origin Garden origin. Conditions Well-drained soil; full sun. Hardiness RHS H5, USDA 6a-9b. Season of interest Summer.
Wand flowers, or more romantically angel’s fishing rods, are one of my favourite perennials. With their wiry, evergreen, grassy leaves, many visitors ask us what the flowering grasses are. Dieramas are actually bulbs that come from South Africa. Most of the species grow high up, which means they can survive in most of the UK.
This species flowers later than most, usually from June to July. The bell-shaped flowers can be pink, purple, white, or pale amethyst. The silvery seedheads that follow are also attractive, moving in the slightest breeze.
Height 1-2m. Origin South Africa. Conditions Well-drained soil; full sun. Hardiness RHS H3-4, USDA 8a-10b. Season of interest Late summer for flowers.
June flowers: the best blooms for June
A dark-pink seedling we raised from Rodgersia pinnata ‘Superba’ while at the Garden House. In the wild, rodgersias often grow on stream banks and like a moisture-retentive soil, without being waterlogged. When this cultivar flowers, the flowerheads turn a dark red color. They look great in dried flower arrangements. The pretty wavy leaves don’t show up until late spring. The flowering stems come up first, so they are more likely to be damaged by late spring frosts at this point. This late leafing means it is possible to grow early spring bulbs among the roots.
AGM. Height 1m. Origin Garden origin, species from China. Conditions Moist but well-drained soil in full sun/part shade. Hardiness RHS H4, USDA 3a-8b. Season of interest All summer.
The Chilean evening primrose in a pale yellow color. This is a short-lived perennial or biennial that I hope I never lose. Since it will spread its own seeds, there should be no reason to lose it as long as there is empty space for the seedlings to grow.
The fragrant flowers open a pale yellow color in the late afternoon, as their name suggests. By morning, each one has turned a beautiful apricot color for its last few hours before falling off. It looks even better because the buds and stems are flushed with purple-red color.
Height 60-90cm. Origin Garden origin (species from Chile). Conditions Any well-drained soil; full sun. Hardiness RHS H5, USDA 6a-10b. Season of interest All summer.
Another plant we raised while we were at the Garden House. A seedling from the pure-white Campanula latifolia var. There is a purple eye and a faint flush of that color in the white that makes this a more elegant-looking perennial. I have never had to stake this plant because it grows straight up, and the clump doesn’t take up much ground space, so it can be used to add height to lower-growing perennials.
After flowering the skeletal seedheads are also attractive for a short period before they are best cut back.
Height 1m. Origin Garden origin (species from Europe and western Asia). Conditions Any soil; full sun to part shade. Hardiness RHS H5, USDA 4a-9b. Season of interest Summer.
