Bishop's Children Dahlia Tuber Collection

Certified Organic Tubers

Dahlia variabilis

Coming Soon!

Single-petaled blooms in red, pink, and yellow adorn burgundy foliage.

All that's left of the Bishop of Llandaff's Palace in Wales is an iron-gated arch entrance flanked by crumbling stone towers. But his gardens live on in the progeny of his dahlia mix. Because dahlias are octoploids, meaning they have four times as many chromosomes as most other flowers, tubers grown from seed produce a spectacular diversity of architectural leaves and blooms in a myriad of forms and colors.

This year we're sharing some of this diversity with you through tubers as well as seed! These tuber sets are a mix of some of our favorite colors and forms that have appeared in the mix during our farm grow-outs.

Bloom colors are a mix of red, burgundy, magenta and the occasional yellow flower on foliage that ranges from purple tinged to deep burgundy.

Because these tube can be produced by us efficiently, we're offering them in larger, value-oriented sizes. These packs represent an excellent value for money, and with their stunning colors set against dark foliage, are an excellent way to fill up your beds and borders with eye-popping beauty.


This lot was produced and processed in the Hudson Valley of New York State on our own certified organic seed farm, Four Fold Farm.

Plant dahlia tubers in late spring when soil temperatures have reached 60 degrees. Frost will kill the plants, so plan to plant around your last frost date. In the Northeast, the window for planting is from around mid-May to mid-June. Dahlias thrive in sunny locations with well drained, fertile, slightly acidic soil. Dig a hole that will accommodate the entire tuber clump, about 6" deep and 6" wide. Plant tuber clump with the "crown" up, just at the surface so all the tubers are beneath. If planting multiple tubers, space at least 12-18" apart. Do not begin watering until the plants emerge. After that, make sure they are watered well 1-2 times per week. In Northern zones with shorter seasons, you can get a jump start by starting dahlias indoors in large pots 4-6 weeks before your last spring frost. Transplant after threat of frost has passed to spacing indicated above. Transplants will need to be watered in. Dahlias reach up to 42" high and might need staking to keep the blooms upright. Dahlias will not overwinter in zones below 8. After the first killing frost, gently dig up tubers and store in peat moss in a cool, frost-free place (40-50 degrees is ideal) until the next planting season.
