About Golden Jubilee Anise Hyssop

Agastache foeniculum 'Golden Jubilee' · also called Golden Jubilee Anise Hyssop, Golden Anise Hyssop · herb

Golden Jubilee Anise Hyssop is a 2003 All-America Selections winner grown for its luminous gold-green foliage and lavender-blue flower spikes. The leaves carry a strong anise-liquorice fragrance and are used as a culinary herb and in teas. An excellent pollinator plant, it attracts bees, butterflies, and hummingbirds through summer and into autumn.

Mature size: 60–90 cm tall, 45–60 cm wide

Watch for — Powdery mildew: White powdery coating appears on foliage late in the season, particularly in humid conditions or crowded plantings. Improve air circulation by thinning nearby plants; cut back affected growth. Resistant to severe damage.

Indoor size vs how big it gets in the wild

Golden Jubilee Anise Hyssop reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 60–90 cm tall, 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.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Golden Jubilee Anise Hyssop is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: apply a balanced slow-release fertiliser in spring. avoid excess nitrogen, which causes lush green growth at the expense of the golden leaf colour and flower production. a low-nitrogen formula (e.g. 5-10-10) is preferred.

How to keep golden jubilee anise hyssop smaller

You are not stuck with the maximum size. For golden jubilee anise hyssop specifically, these are the levers, in order of impact:

Choose a compact or dwarf variety of golden jubilee anise hyssop from the start — that is the most reliable size control for an annual.
Grow it in a smaller container to naturally limit how large it gets.
For some crops, pinching or pruning the growing tips keeps the plant shorter and bushier.
Sow a little later or space plants closer if you specifically want smaller individual plants.

How to grow golden jubilee anise hyssop bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for golden jubilee anise hyssop the accelerators are:

Full sun, warm soil and steady water are what drive a crop to full size fastest.
Sow at the right time for your zone so it gets the whole season to size up.
Feed appropriately for the crop and never let it check (stall) from drought or cold.

Light is almost always the ceiling. The golden jubilee anise hyssop light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When golden jubilee anise hyssop outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for golden jubilee anise hyssop:

It sprawls beyond its bed or container before harvest — usually a spacing or support issue.
It flops or needs staking once it hits full height.
Once it has fruited or bolted, it is at its final size for good — the next plant is a new sowing.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the golden jubilee anise hyssop repotting guide. If you want more of this plant instead of a bigger one, the golden jubilee anise hyssop propagation guide turns prunings into new plants.
