About Miss Jekyll love-in-a-mist

Nigella damascena 'Miss Jekyll' · also called Miss Jekyll love-in-a-mist, love-in-a-mist · flowering

Miss Jekyll is an heirloom cultivar of love-in-a-mist producing semi-double sky-blue flowers nestled in feathery, fennel-like foliage, followed by ornamental seed pods. Direct-sow in situ in full sun on free-draining soil. Self-seeds prolifically. A cottage garden classic valued for cut and dried flowers.

Mature size: 45–50 cm tall (18–20 in), spread 15–23 cm (6–9 in)

Watch for — Poor germination after transplanting: Nigella has a taproot and resents root disturbance. Always direct-sow in final position; transplanted seedlings often bolt or fail. Sow where they are to grow.

How to tell miss jekyll love-in-a-mist needs repotting

Repotting on a calendar is less reliable than reading the plant. For miss jekyll love-in-a-mist, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot miss jekyll love-in-a-mist on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot miss jekyll love-in-a-mist

Pot on seedlings as they grow; not a perennial repot. Miss Jekyll love-in-a-mistis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Upright, branching annual with finely dissected, thread-like foliage. Produces flowers on slender stems 45–50 cm (18–20 in) tall, followed by attractive inflated seed pods..

What size pot to step miss jekyll love-in-a-mist up to

Pot miss jekyll love-in-a-mist on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot miss jekyll love-in-a-mist

Pot miss jekyll love-in-a-mist on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting miss jekyll love-in-a-mist

Pot on before it is root-bound. Check miss jekyll love-in-a-mist regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh light, well-drained, poor to moderately fertile at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water miss jekyll love-in-a-mist in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for miss jekyll love-in-a-mist

Miss Jekyll love-in-a-mist wants light, well-drained, poor to moderately fertile. Thrives in sandy or chalky, well-drained soils with a pH of 6.5–7.5. Rich, fertile soils produce excessive foliage at the expense of flowers. Does not require amendment beyond basic drainage improvement. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting miss jekyll love-in-a-mist — frequently asked questions

How often should you repot miss jekyll love-in-a-mist?

Pot on seedlings as they grow; not a perennial repot for miss jekyll love-in-a-mist. Miss Jekyll love-in-a-mist is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into light, well-drained, poor to moderately fertile so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does miss jekyll love-in-a-mist need?

When is the best time of year to repot miss jekyll love-in-a-mist?

Can you put miss jekyll love-in-a-mist straight into a much bigger pot?

No. Even a fast-growing miss jekyll love-in-a-mist should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise miss jekyll love-in-a-mist after repotting?

Not immediately. Wait about 1 week after repotting miss jekyll love-in-a-mist. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
