About Daylily 'Bumble Bee'

Hemerocallis 'Bumble Bee' · also called Bumble Bee daylily, bicolor miniature daylily · flowering

Hemerocallis 'Bumble Bee' is a charming miniature daylily bearing bright yellow flowers with a contrasting dark burgundy-red eye zone in mid-summer. The compact habit makes it ideal for edging and pots. Toxic to cats — the entire plant including pollen can cause acute kidney failure — keep away from cats entirely.

Mature size: 30-45 cm tall in bloom; clumps 35-45 cm wide

Indoor size vs how big it gets in the wild

Daylily 'Bumble Bee' 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 30-45 cm tall in bloom. In the ground with no restriction it is a completely different plant — clumps 35-45 cm wide — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

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 'Bumble Bee' 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: topdress with a balanced slow-release fertiliser in spring. a single liquid feed with a high-potassium formula in early summer promotes bud set and intensifies the eye colouring. avoid high-nitrogen feeds which promote foliage over flowers.

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

How to keep daylily 'bumble bee' smaller

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

Divide the clump every year or two — splitting daylily 'bumble bee' 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 'bumble bee' 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 'bumble bee' bigger or faster

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

When daylily 'bumble bee' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for daylily 'bumble bee':

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