Our dahlias:

  • are first class, healthy tubers – the largest and best you can buy.
  • come with full planting, spacing and cultivating instructions for beginner gardeners
  • tubers should be potted up when they arrive and be kept in a light, frost-free place until the frosts are over and then be planted into the garden.

Genus Dahlia
Group/Species Decorative Group
Variety Sam Hopkins
Type Tender Perennial Tuber
Border Position Middle
Bulb Size I
Soil Type Acid, Chalky, Fertile, Neutral
Scent Unscented
Site Full Sun
Moisture Moist but Well-drained
Height 1m (39in)
Spacing Plant just under the soil surface, 75cm (30in) apart.
Sowing, Seeds, Planting Pot them up undercover March or early April in a generous pot (at least 2 litre) filled with multi-purpose potting compost. Place them in a light, frost-free place and keep the compost moist. Pinch out their growing tips when they have reached about 8" tall. They will have formed bushy plants by the time the frosts have ended and will be in flower by the beginning of July. If you don’t have anywhere to grow the potted tubers, you can put them straight into the ground when the frosts are nearly over, mulching them or protecting with a cloche or protective horticultural fleece if the foliage appears before the frosts are over, but this will delay flowering.
Care Tips Support with a stout stick, tie in every couple of weeks. In the south you can mulch deeply and overwinter them in the ground, alternatively, lift and overwinter your dahlias frost free undercover.
Flowering July - November
Vase Life Only pick dahlias in full flower. Recut the hollow stem ends under water to avoid airlocks.
Cooking Notes All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings.

Stunningly beautiful

Reviewed 20th June 2018 by Louise johnson

I grew Sam Hopkins last year from the Venetian collection, I started with a large and healthy tuber. From this grew the most stunning plant I could have imagined. The flowers were so beautiful that I couldn’t stop looking at it and admiring it. So much so that this year instead of growing just 1 Sam Hopkins, I have 4 planted. My original one (dug up and overwintered - it was huge in the autumn when I dug it up) and 3 new tubers which I couldn’t resist ordering. The tubers from Sarah raven are substantial - I even managed to take some cuttings too. Try this dahlia you won’t be disappointed!

I bought this from Sarah years ago and wouldn't be without it. It's been in pots, in the ground, it's moved countries and paired with my favourite salvia, Amistad, it gives me the most enormous pleasure. A sublime dahlia.

Velvety Delight!

This dahlia came as part of the Venetian Collection that I ordered a couple of years ago, I overwinter it and replant each year and it just gets better and better. It is a stunning colour, clear and velvety at the same time if that's possible, with a really dark rich centre and fresh zingy green foliage - just delightful.
