Dinnerplate Dahlias

Planning your summer borders in January is a constant battle between excitement and impulse, and careful planning. Yes, you might see all the summer-blooming tubers and bulbs coming out on the market around this time – and you might feel tempted to buy now and deal with the fallout later – but just hold your horses for one second, and don’t buy anything until you’ve read about these huge (and I mean HUGE – 12” in diameter, in fact) Dinnerplate Dahlias.

What are Dinnerplate Dahlias?

These extra large dahlias have enormous blossoms ranging from 10” to 12” across, making them the largest dahlias available. First introduced to the market by Belgium in the early 1800s, Dinnerplate Dahlias are just as fashionable now as they were back then.

Because Dinnerplate Dahlias are so big, they’ll fill your borders with vivid colour for less! Once you’ve got your tubers in place, you can fill around them with other plants such as crocosmia, calendula and rudbeckia, and you won’t need as many plants to make an impact.

Things you should know

Dinnerplate Dahlias must always be staked in the garden. These dahlias aren’t just heavy-blossomed; they’re also tall, with fragile stems that will bend and snap in the wind (but not in a fun, Legally Blonde kind of way). Stake your dahlias for a low cost using bamboo cane and twine. Push four bamboo canes into the ground around each flower, then wrap the twine around the stem and the canes to keep it upright as it grows.

Can Dinnerplate Dahlias be used as cut flowers?

Absolutely! Dinnerplate Dahlias look incredible in a vase – although they may outshine other flowers in the bouquet, so instead of including lots of other competing blooms, try using a few filler-style plants, such as Lady’s Mantle, ferns and ivy stems.

Why not try a minimalist one-flower vase instead?

Also included is a 100g pack of Thompson & Morgan’s Incredibloom, a complete plant fertiliser that will feed your dahlias the right nutrients as and when they need them. With a complete balance of NPK, all you need is one application to get the best out of your blooms.
