About Leopard Plant 'The Rocket'

Ligularia stenocephala · also called The Rocket Ligularia, Narrow-Spiked Ligularia · flowering

Leopard Plant 'The Rocket' is a dramatic moisture-loving perennial with deeply toothed, triangular leaves on dark stems and tall, narrow spikes of vivid yellow flowers in mid-summer. The upright flower spikes make it among the most architectural of all ligularias. Best in moist to wet, shaded conditions. Treat as mildly toxic with pets.

Plant type: flowering

Watch for — Aphids on flower spikes: Aphid colonies may colonise stems; blast with water or apply insecticidal soap.

The reasons leopard plant 'the rocket' isn't blooming

Almost every non-blooming leopard plant 'the rocket' 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 leopard plant 'the rocket' 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 leopard plant 'the rocket' to flower

Maximise sun. Give leopard plant 'the rocket' 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 leopard plant 'the rocket' and get the feeding right with the leopard plant 'the rocket' 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

Leopard Plant 'The Rocket' 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.
