Pennisetum alopecuroides ‘JS Jommenik’ Lumen Gold®

Golden highlights in airy foliage ☀️

Family: Poaceae · Pot diameter: 19cm (3 litres) · Height: 20cm

Gold to lime foliage
25–35cm foliage
Warm-season growth
ISU Award 2018

Pennisetum alopecuroides ‘JS Jommenik’ Lumen Gold® is a compact golden fountain-grass selection that brightens the foreground without weighing it down. Its rounded basal tussock opens almost lemon-yellow in spring, softens to fresh lime through summer and lifts fine bottlebrush panicles above the foliage into autumn. The narrow blades bend together instead of collapsing untidily, creating a calm ripple with a crisp outline that makes neighbouring purple, pink or white flowers appear even richer.

Its colour follows a genuine seasonal sequence: gold at emergence, fresh lime in summer heat, then yellow-orange to straw later in the year. This is a warm-season grass, not a permanently yellow evergreen ball; frost may collapse the leaves, while a mild site can preserve some standing foliage.

In current taxonomy, Pennisetum alopecuroides is treated as Cenchrus alopecuroides. The selection ‘JS Jommenik’ Lumen Gold® received an ISU Award in 2018.

What makes it special

A low luminous tussock that changes colour through the season and adds slender panicles without screening neighbouring plants.

Luminous low base

The semi-globular tussock emerges golden-yellow and remains lower than its parent ‘Gelbstiel’.

Three seasons of colour

Foliage moves from gold through lime to yellow-orange or straw.

Fine floating panicles

Narrow bristly panicles rise above the leaves from summer into autumn.

Why you will love it: it provides a long colour sequence, movement and a crisp outline at a scale that fits the very front of a border.

In the garden & on the balconyPlacement & plant combinationsLuminous foreground · full sun · mature spread 30–45cm

Planting position

Golden low foreground

Place at the sunny front of a border, in repeated groups or in a broad pot with free winter drainage. Allow about 40–50cm between mature tussocks so the rounded outline remains distinct.

Colour & compatibility

Gold with violet

Yellow and lime blades gain depth beside violet flowers, flat heads and the quiet pinks of autumn.

Salvia nemorosa — upright violet spires above the low golden base.
Achillea millefolium — flat flower heads sharing its preference for sun and drainage.
Hylotelephium ‘Herbstfreude’ — pink to dusky heads that accompany the autumn colour.

Care at a glance

Light

Full sun for the strongest gold and most panicles; light shade makes the foliage greener.

Watering

Water regularly until rooted, then deeply and less often, never leaving water around the crown.

Climate & hardiness

Warm-season and not reliably evergreen; winter response varies with frost, moisture and exposure.

Safety

Not intended for consumption; wear gloves when handling dry leaves and mature panicles.

Detailed careComplete care guideEight practical points: Position, Watering, Soil, Feeding, Seasonal behaviour, Division, Safety, Seed control.

Position

Give it the sunniest practical position for golden foliage and compact growth.

Watering

Water through the first growing season; established tussocks tolerate only short dry spells.

Soil

Light to moderately fertile and freely drained, with the crown slightly above final soil level.

Feeding

Feed lightly in spring; excess nitrogen produces softer, greener growth.

Seasonal behaviour

Leave dry structure only where seeding is not a concern, then cut dead growth to 8–15cm before new shoots.

Division

Divide congested tussocks in late spring or early summer when the centre becomes overly dense or new growth weakens.

Safety

Wear gloves when handling the narrow blades and dry panicles; do not treat the plant as edible or specifically pet-safe.

Seed control

Sterility is unproven; remove mature panicles and check nearby soil where seedlings would be unwanted.

Development over timeHow the golden tussock lights upThree stages from golden spring emergence to panicles and a straw-coloured winter structure.

Golden emergence

New blades rise bright yellow as warm-season growth begins.

Lime with panicles

Foliage settles to lime and narrow bristly panicles rise above the tussock.

Straw dormancy

Cold turns the blades yellow-orange or dry until spring renewal.

Mature habit & dimensions

established mature plant

Foliage 25–35cmPanicles to about 60cmSpread 30–45cm

Mature Cenchrus alopecuroides ‘JS Jommenik’ Lumen Gold® rises from a dense basal tussock and carries fine panicles without losing its low outline. It works as a luminous repetition in a border or as a moving specimen in a pot.

Form through time

two real states

Genuine seasonal cycleGold, lime and straw

Golden emergenceNew growth opens yellow from the base.

Panicles and ripeningLime leaves carry panicles before turning straw.

The drawings connect basal emergence with the summer-to-autumn display of panicles.

What to expect after planting: Once rooted, each warm season rebuilds the low tussock from its base. Golden emergence becomes a lime background for the panicles, then closes in warm straw tones.

History & originCultivar originJan Spruyt · Buggenhout, Belgium · shoot sport found 2007

In summer 2007, Belgian nurseryman Jan Spruyt noticed a differently coloured shoot on an unpatented Pennisetum alopecuroides ‘Gelbstiel’ at his nursery in Buggenhout. He retained this spontaneous sport for its lower, bushier habit and yellow-green foliage.

The selection was increased asexually by division and later through tissue culture. Successive generations remained stable, preserving the luminous colour and low, compact form of the original sport.

The Community Plant Variety Rights application was filed on 9 September 2014 and title 44184 was granted in 2016. The US application followed on 11 December 2015, and US Plant Patent 27,435 was granted on 29 November 2016 under the denomination ‘JS Jommenik’.

Because ‘JS Jommenik’ was awkward as a retail name in North America, Plantipp created the selling name Lumen Gold, referring to its almost luminous colour in sun. The selection received an ISU Award in 2018.

Greenleaf for Plant NerdsScience nobody asked forBotanical details for anyone curious about what lies behind the plant’s appearance

Narrow luminous blades

The narrow blades can reach about 23 × 0.4cm, with sparse soft hairs and parallel venation.

Basal architecture

Leaves and culms emerge from a compact crown and form a semi-globular tussock, not a woody shrub.

Panicles, not one flower

Each bottlebrush head is a narrow panicle containing many small spikelets surrounded by bristles.

Frequently asked questions

Six specific answers about identity, size, the seasonal cycle, light and management of the tussock.

01Is Lumen Gold the cultivar name?

No. Lumen Gold is the selling name; ‘JS Jommenik’ is the registered cultivar denomination.

02How large does it become?

Foliage usually forms a tussock about 25–35cm high, flowering stems reach up to about 60cm and the spread is roughly 30–45cm.

03Is it evergreen?

Not reliably. It may retain foliage in a mild winter but commonly bronzes or dies back after frost.

04How hardy is it?

Winter performance depends strongly on drainage, winter moisture and exposure; free drainage and crown protection are safer guides than an absolute temperature promise.

05Sun or shade?

Full sun gives the strongest gold and most panicles; light shade produces greener foliage.

06Is it sterile?

Sterility has not been demonstrated. Remove mature panicles and monitor for unwanted seedlings near sensitive places.
