Flowering Period

Eliminate the wait for your plants to mature with our XXL Bare Root Plant range. Planting these XXL clumps offers numerous advantages, particularly for achieving a quicker, more impactful and vibrant display, especially with varieties like Agapanthus, Geraniums or Peonies. These larger clumps, of established plants, provide immediate visual impact by having a well-developed robust root system and multiple green buds, all of which are individual plants which will spring to life once you plant them and work together to provide you with a stunning display from the first year of planting. They are also a great way to overcome the chance of losing younger plants to drought conditions as they are more mature and therefore drought-tolerant once planted.

Growing Information

Iris pseudacorus plants thrive in damp, acid or neutral soil in a sunny or semi-shaded position. These moisture loving Iris require a rich, fertile soil which has had plenty of well rotted organic matter added into the soil prior to planting. Grow Iris pseudacorus in moist, boggy soils or submerged in the shallow margins of ponds with the crown to a maximum depth of up to 20cm (8") below water level. Choose a position in sun or semi shade.

Live Plants

Suttons strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.

Non Standard Deliveries

Unfortunately like many companies in our industry we are currently only able to supply orders to UK based customers, excluding those in Northern Ireland. We are committed to finding a way that we can resume or normal services again as soon as possible. Please accept our apologies for any inconvience caused.

Prices include VAT where applicable.

We reserve the right to contact you and advise an additional charge where necessary and are happy to quote for carriage of specific products to more remote areas. Some items may not be available to all areas.

We reserve the right to revise any carriage charges in the event of carrier price increase or other unforeseen circumstances. We will always advise of the carriage charge before payment is taken.

All Suttons products should reach you in perfect condition, just as they left us. If you are dissatisfied in any way with their condition on arrival, please let us know within 14 days. We are only liable for the cost of the goods as quoted on the website plus the cost of delivery if the goods are faulty.

Why Not Try This Instead

What our customers say

"Very impressed with the quality of leek and broad bean seeds you sent. Excellent germination and look forward to a bumper crop. Will certainly be back."

E. Smyth

“I bought all my seeds, potatoes, etc. from your catalogue last year for my new ‘larger’ vegetable garden. I have to say I have never had such success in the garden. The germination was excellent; the quality of plant stock and produce is superb."

Sadie

“I am compelled to write to you and your staff for the exemplary service provided by your company, in an age where the word and term ‘service’ has lost its meaning.”
