Native wildflowers are plant species that naturally occur in a specific region and
have evolved over time alongside local wildlife, soil, and climate.

Native plants are better adapted to local conditions, and more importantly they support much more native wildlife and pollinators.

Yes, once established. They are naturally suited to local soils and weather, so they generally need less watering, fertiliser, and pest control.

Native wildflowers are one of the best ways to support bees, butterflies, and other beneficial insects. These in turn attract insectivorous birds, reptiles, amphibians and small mammals.

The best choices depend on your soil type, sunlight, and location. We recommend selecting plants that naturally grow in conditions similar to your garden. You can search by habitat or soil type on our website. E.g. if you are looking for plants that can tolerate shade, just type in ‘Shade’ in the search bar.

Yes, we offer wildflowers for a range of environments, including full sun, shade, dry soils, and damp areas. You can search by habitat or soil type on our website. E.g. if you are looking for bog plants, just type in ‘Bog’ in the search bar.

Start by assessing your site (sunlight, soil, moisture). From there, choose a mix
suited to those conditions. Work with your soil type and not against it.

Yes, all our native plants are grown at our nursery in Penllergare to ensure they are well adapted to the British climate.

Yes! We have always been a 100% peat free nursery using professional grade peat free compost.

No. We grow or hold seed of over 400 native species with assured British provenance. All the seed we use to grow our plants is hand collected by ourselves, processed and stored on site. We then sow this seed to grow our local provenance wildflowers. Note, we do not sell this seed, though we do buy in some seed upon request for specific projects.

Spring and autumn are ideal. Autumn planting produces stronger plants, as the roots have a longer period over the winter to harden off and establish.

This is variable, but typically clearing existing vegetation, remove undesirable weedy species, and lightly cultivate the soil will produce good results. Wildflowers prefer low-nutrient soils, so avoid adding fertiliser. If you are planting into grass, we recommend you sow Yellow Rattle seed in the Autumn. This seed likes to stratify over the winter.

If it is dry for a period after planting, watering during the establishment phase. Thereafter, most native wildflowers require little additional watering.

Annuals are as the same suggest, plants that survive one season. Through they will deposit seed and if suitable, will grow next year. Biennials grow the first year, flower the second year and then they die. Perennials return each year and form the majority of the plants we grow. Appropriate management is important for maintaining and developing flower rich habitats, in many cases a late summer cut, removing the arisings, is all that may be required.

Annuals may bloom within a few months. Perennials take longer, sometimes even one to two years to fully establish.

No, wildflowers generally thrive in poorer soils. Fertiliser can encourage grasses and ‘weedy’ species to become overly dominant.

There is a wide range of native species attract pollinators, in fact every native flowering species has a suite of associated invertebrates that will utilise a plants flowers fruits or foliage, providing biodiversity. Our pollinator mixes are specifically designed to provide nectar throughout the growing season. You can search our website by typing in ‘Pollinators’ or ‘bees’ in the search bar on our website.

Yes, planting native wildflowers is the easiest way to create habitats and food sources for the multitude of insects, birds, and other wildlife found in Britain.

Most native wildflowers are safe, but some species can be toxic. We recommend checking individual plant details if you have concerns.

Not typically. A healthy wildflower area encourages beneficial insects that help keep pests in balance.

We offer British provenance seed for our seed packets that we buy in, as we cannot financially sell on our local provenance hand collected seed. ALL of our plants are grown from OUR own locally collected seed to grow and sell plugs, 9cm pots, 1L and 2L pots etc.

Seeds are more economical and ideal for larger areas. Plug plants are young plants that establish more quickly and give more reliable results.

We normally suggest planting 10-15 plants per square metre for impact planting, such as in small garden beds or planters. For large areas, we suggest cluster planting in groups of 5 in areas from which plants can set seed and spread naturally.

Yes, we offer discounts for larger orders, please contact us for details.

Yes, we deliver across the UK but not overseas.

Please read our full Shipping Policy here.

Delivery times vary but are usually within 3-10 days. We ship plants on a Monday, Tuesday and Wednesday.

Plants are carefully packed to protect them in transit and ensure they arrive in good condition. You may sometimes see bubble wrap or plastic fillers. We do not buy this in, but we do re-use wrap that has been donated to us.

Yes, local collection is available by arrangement.

Plugs, bare-rooted plants, pots and bulbs are deemed as perishable items and a refund will not usually be granted.

Regarding seed, there will be a 14-day calendar window in which the seed can be returned.

Please read our full Refund Policy here.

We have a help sheet on our website that you can use as a guide to help you.

Yes, we grow many native species at home and at the nursery in pots and window boxes. The calcareous plant section provides a huge list of suitable species to choose from. Get in touch if you need advice.

We do not provide a design service but we do have an ecological consultation service. Email us for details: sales@celticwildflowers.co.uk

Initial growth appears in the first year, but full establishment typically takes 2 - 3 years.

Yes, we avoid harmful pesticides to protect wildlife and soil health.

Yes, we are 100% committed to using peat-free growing media.

Sustainability is at the core of what we do, from sourcing to growing and packaging.

Common reasons include poor soil preparation, incorrect sowing time, lack of moisture, or competition from weeds.

Weeds are natural in early stages. Proper preparation and ongoing management will help wildflowers establish dominance.

Check watering, soil conditions, and sunlight. If problems persist, feel free to contact us for advice.
