About Daylily 'Midnight Magic'

Hemerocallis 'Midnight Magic' · also called Midnight Magic daylily · flowering

Hemerocallis 'Midnight Magic' is a dramatic mid-season daylily producing near-black, deep burgundy-purple flowers with a yellow-green throat. It is prized for its intense, velvety colour in sunny borders. Toxic to cats — all daylily parts can cause fatal kidney failure in felines. Not safe for cat-owning households.

Mature size: 60-70 cm tall in flower, clumps spreading to 45-60 cm wide

Watch for — Aphids: Found on tender new growth in spring; blast off with water or apply insecticidal soap. Check regularly as daylilies in active growth are attractive to aphid colonies.

Indoor size vs how big it gets in the wild

Daylily 'Midnight Magic' 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 60-70 cm tall in flower, clumps spreading to 45-60 cm wide. 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

Daylily 'Midnight Magic' 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 slow-release granular feed in early spring. supplement with a liquid high-potassium feed when scapes begin to emerge to support flower development. avoid high-nitrogen feeds that encourage leafy growth over blooms.

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

How to keep daylily 'midnight magic' smaller

You are not stuck with the maximum size. For daylily 'midnight magic' specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting daylily 'midnight magic' 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 daylily 'midnight magic' 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 daylily 'midnight magic' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for daylily 'midnight magic' 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 daylily 'midnight magic' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When daylily 'midnight magic' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for daylily 'midnight magic':

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 daylily 'midnight magic' repotting guide. If you want more of this plant instead of a bigger one, the daylily 'midnight magic' propagation guide turns prunings into new plants.
