(Paniculate hydrangea) A deciduous and potentially large upright shrub with slightly glossy mid-green leaves. In mid-summer Hydrangea paniculata 'Kyushu' produces upright pyramidal panicles of creamy-white flowers and is noticeably earlier into flower than other varieties..

Botanically speaking, the flower heads mainly comprise the larger and more showy sterile florets that surround the small fertile flowers. There is good evidence to suppose that these large sterile flowers act as 'honey guides' to attract pollinating insects.

Generally speaking the more mature and larger the plant, the larger the flower panicles. Hence, hard pruning, in spring, will tend to produce a more compact plant with smaller flower heads, whilst light or no pruning will result in not only a larger plant overall but one proportionately large flower heads. As a guide, an established plant could be cut back to about three feet in height, just above the pairs of buds you will find on each stem, some time during March.

Hydrangea paniculata grows wild in Japan, where it has been seen growing as a quite substantial tree, as well as Sakhalin, and eastern and southern China. It was introduced into the UK in 1861. The variety 'Kyushu' was collected on Kyushu Island in 1926.

Hydrangea paniculata 'Kyushu', in common with other hydrangeas will appreciate quite cool and shady conditions, so plant in soil that is rich in organic matter, which does not get aggressively dry in summer, and in a position which offers some shade from the full heat of the mid-day sun. If you are planting in full sun you will tend to get a more compact plant, and you may need to water the plant during a mid-summer heat wave - otherwise, full sun will be tolerated.

Probable height in the UK will be in the region of 2 to 3m, depending on the pruning regime. Hydrangea paniculata 'Kyushu' can be confidently considered fully hardy, but the young spring growth may be prone to damage from cold winter winds or a sharp frost. Consequently plant in a slightly sheltered part of the garden and avoid a frost pocket, such as the bottom of the slope where cold air cannot flow away.

We are a small and very busy working nursery and we do not have the capacity to continually update pot size information on our web shop as we are continually propagating and potting plants up.  Therefore any one plant type may be in different pot sizes at different times of year.  However, we hope the following notes will be useful

1.  We do not sell any plants in 'plug' sizes - all our plants are of a size that is appropriate for planting out in the garden.

2.  Early in the year herbaceous perennials may be in 9cm (1/2 litre) or one litre pots.  As we enter summer a lot of herbaceous perennials move on to 2 litre, 3 litre and occasionally 4 or even 5 litre pots.

3.  Shrubs are generally in 2 litre pots at minimum, moving up to 3, 4 and 5 litres as appropriate, occasionally 7.5 litres or even 10 litres

4. Our smallest trees may be in 3 litre pots but are generally in 7.5 to 10 litre pots, some moving on to 15 litres and occasionally 20 litres

5.  Flowering dogwoods, one of our specialities, are in pots ranging from 7.5 litres to 15 or occasionally 20 litre pots.

If you want to know the specific pots size of a plant please use the 'contact us' feature on the web shop, or call us on 01953 488163, although as we spend so much time on the guessed it... propagating and potting up plants you may need to leave a message which we will endeavour to answer the same day.

Our minimum charge for sending plants by overnight courier is £9.95 which will cover the cost of up to 10 small plants, for example herbaceous perennials.  This is an overnight service from when your plants leave the nursery which is normally Thursday, to arrive Friday - all ready for a great weekend in the garden.

The amount charged is calculated on the notional weight of plants, and you will find that a number of small plants, for example herbaceous perennials in 9cm, one litre or even two litre pots, can be bought for the same £9.95 shipping charge. 

Adding additional plants to your order will progressively, but moderately,  increase the shipping charge, but this is made entirely explicit in your shopping basket, where you can add or remove items and watch how the shipping charge alters accordingly.  The maximum charge for delivery is £18.95 which would cover an unlimited number of plants.

Due to the fact that, including the cost of the boxes and so on, we pay considerably more than £9.95 for each shipment, our delivery charges are in effect subsidised by us.  For that reason we have to ask for a minimum purchase of £25 before delivery in order minimise our losses.

For shipping to remoter addresses, for examples Highlands and Islands, Northern Ireland and so on, please contact  us and we will be able to provide you with a quotation.

We try to run Walnut Tree Garden Nursery in the most environmentally friendly manner possible.  These are some of the steps we have taken:

1. We only use peat free compost although occasionally young plants and propagation stock arrives in peat-based composts.  The balance of composts on the nursery is at least 90% peat free compared to peat.

2. We clean and re-use long life plastic pots where possible.

3. Customers can return the pots that came from us for re-use.

4. No single-use pots or trays (e.g. polystyrene bedding trays) are ever used.

5. We always hand water and do not use overhead sprinklers in order to minimise water waste.

6. We use biological control of pests where possible (e.g. parasitic nematodes against vine weevil)

7. We only use the bare minimum use of pesticides and fungicides – strictly on an 'as needed’ basis –after dusk and only on foliage to protect pollen and nectar seeking insects.

8. Mains electricity is 100% renewable, purchased from Bulb

9. Electricity is also supplied by on-site photovoltaic panels during daylight hours

10. Since May 2020 we donate to carbon-offset projects in order to compensate for carbon emissions relating to all aspect of our business (pot and compost production, deliveries, mail order couriers, leaflet printing and so on) .  As of November 2020 we have purchased 28 tonnes of carbon offsets.

11. We propagate as much of our stock on-site as possible, which reduces carbon miles.  Propagation material that we buy in is at as small a growth stage as possible to minimise carbon miles.  We often propagate from seeds: for example, a batch of seeds arriving by post might weight no more than 50-100 grams but which we will grow on to produce to 2-3,000 plants, in peat free compost, often in pre-used pots.

12.  In addition to all the herbaceous perennials and woody shrubs that we sell, we also sell approximately 500 trees annually.  Therefore, since we started the business in 1998  we have sold some 21,000 trees, hopefully leading to a cascade of environmental benefits in our customer's gardens.
