About Zantedeschia 'Hot Chocolate'

Zantedeschia 'Hot Chocolate' · also called Hot Chocolate calla lily, chocolate-maroon calla · flowering

Zantedeschia 'Hot Chocolate' is a hybrid calla lily with rich brown to maroon spathes flushed ruby, set against dark green foliage. This tender tuberous perennial wants warmth, bright light and fertile, moist, free-draining soil. Lift and store the rhizome dry in frost-prone areas. A bold container and border plant reaching roughly 50-75 cm.

Mature size: Roughly 50-75 cm tall with a 30-45 cm spread.

Indoor size vs how big it gets in the wild

Zantedeschia 'Hot Chocolate' stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect roughly 50-75 cm tall with a 30-45 cm spread.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Zantedeschia 'Hot Chocolate' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced to potassium-rich liquid feed every 2-3 weeks through active growth to fuel flowering. limit nitrogen to avoid lush foliage at the expense of blooms, and stop feeding as dormancy approaches.

Want this turned into the right next pot at the right moment? The pot size calculator and the zantedeschia 'hot chocolate' repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast zantedeschia 'hot chocolate' grows.

How to keep zantedeschia 'hot chocolate' smaller

You are not stuck with the maximum size. For zantedeschia 'hot chocolate' specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting zantedeschia 'hot chocolate' is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide zantedeschia 'hot chocolate' out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow zantedeschia 'hot chocolate' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for zantedeschia 'hot chocolate' the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The zantedeschia 'hot chocolate' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When zantedeschia 'hot chocolate' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for zantedeschia 'hot chocolate':

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the zantedeschia 'hot chocolate' repotting guide. If you want more of this plant instead of a bigger one, the zantedeschia 'hot chocolate' propagation guide turns prunings into new plants.
