White Supreme Sweet Pea

The best white sweet pea at the moment, White Supreme has a restrained ruffled look that is elegant and sassy while harking back to its grandiflora origins. A pure, but not blindingly white flower can reach up to 6 cm across and you may get several on each long, sturdy stem. As a Spencer sweet pea the fragrance is not quite as strong as some of the old-fashioned varieties but the size of the flower and the fact that its stems will be straight more than make up for this! It has slightly grey-green foliage which looks pretty with the flowers. It can happily reach 2 m tall indicating its stamina and the number of flowers that you will proudly grow. One of the best sweetpeas you can buy.

It may appear obvious, but a white sweet pea 'goes with' all the other coloured sweet peas and is particularly effective against some of the flakes like America or Raspberry Ripple. Its excellent cutting flowers last well in a vase so for anyone thinking of growing sweet peas for a summer celebration of any sort, White Supreme should be on your short list at the very least. Growing sweet peas with Runner beans in a potager is a win-win for both plants because the scent of the sweet peas attracts many pollinators which will result in many more beans. Be prepared for a glut! Choose white flowering beans like White Lady or Czar for maximum effect.

RHS AGM

From White to Supreme

White Supreme was raised by Bernard Jones and was introduced to the market by Boltons. It received its RHS AGM in 1994.

White Supreme Sweet Peas do best in well worked, moisture retentive soil. Adding organic matter really makes a difference and is best done the autumn before. But on the day is very much better than not at all. Your plants will do best in open ground, but you can get good results planting Sweet Peas in window boxes and pots of sufficient size - allow at least 3 litres per plant and remember that these are quite deep-rooted plants. In containers, the ideal planting mix is 50% compost, 40% topsoil and 10% well-rotted manure. Ordinary potting compost is OK, but you will get fewer flowers.

A range of supports can be used from twiggy branches to willow wigwams to posts with netting stretched between. Whatever you use, do the construction work before planting. Think about the position - Sweet Peas can cope with a little shade but flower better in full sun.

Space plants about 30 cm apart and about 5 cm from their supports. The hole should be deep enough to plant the full length of the rootball and allow enough so the soil finishes level with the lowest pair of leaves. Check to make sure they are climbing well every week or so, as they grow quickly. Tie into their supports if not.

Sweet Peas biggest need is for water - they are incredibly thirsty plants. So water well after planting and make sure they never completely dry out. They are greedy too so you will lengthen their flowering period if you give them a high potash and phosphate fertiliser every 7-10 days once buds begin to form. Home-made comfrey liquid is perfect or Tomorite will do - especially if you are on a sandy soil.

Cut the flowers as they develop pick them, otherwise they run to seed and stop flowering.

We will email you the day before your plants are due to arrive.

*Surcharges to the Highlands and Islands still apply.

Payment: We do not charge your card until we begin to prepare your order for packing.

Guarantee: If any plants die within a year, we will replace them. We only ask that you follow our planting & growing instructions and sent us clear photographs of the dead plants in situ, so we can help to make sure that the replacement plants succeed. You only pay for the delivery of the replacements.

Please note that our guarantee is void if there is a hosepipe ban in your area: your newly planted hedging must be watered in dry weather while it is establishing. The best way to water is very thoroughly every few days: at least once a week if there is no heavy rain.

Our nursery has been supplying container grown and bareroot hedging plants to gardeners, farmers and town planners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying hedging plants online. If any of your plants are damaged when they arrive or if you are otherwise not satisfied with your order after you inspect it, please repackage it and contact us. We will give you a refund or send replacements and send a courier to come and collect the unwanted plants.
