About Double-Flowered Bloodroot

Sanguinaria canadensis 'Multiplex' · also called Double-flowered bloodroot, Double bloodroot · flowering

Double-flowered bloodroot is a prized spring-ephemeral wildflower native to rich, moist deciduous woodlands of eastern North America; 'Multiplex' is a sterile double-flowered cultivar whose stamens are converted into extra petals, producing a dense white pompom-like flower that persists for up to two weeks — far longer than the single-flowered species. After flowering in early spring the distinctive grey-green, lobed leaves persist until late summer before the plant goes fully dormant. Plant in partial to deep shade in humus-rich, well-drained soil and do not disturb the fleshy rhizomes once established. All parts of this plant are toxic to cats and dogs.

The reasons double-flowered bloodroot isn't blooming

Almost every non-blooming double-flowered bloodroot traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding double-flowered bloodroot a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get double-flowered bloodroot to flower

Maximise sun. Give double-flowered bloodroot the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for double-flowered bloodroot and get the feeding right with the double-flowered bloodroot fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Double-Flowered Bloodroot flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full double-flowered bloodroot care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Double-Flowered Bloodroot blooming — frequently asked questions

Why won't my double-flowered bloodroot flower?

Double-Flowered Bloodroot blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make double-flowered bloodroot bloom?
