Is hyssop the same as anise hyssop?

No — completely different plants, different families. Hyssop (Hyssopus officinalis): the herb on this page — semi-shrubby Mediterranean perennial, narrow leaves, blue spike flowers, strong minty-bitter flavour. Anise hyssop (Agastache foeniculum): a North American perennial in the mint family, broader leaves, lavender flower spires, sweet aniseed-mint flavour, used for tea. Both are good bee plants but genuinely different. Buy by Latin name to be sure. See separate anise-hyssop slug.

Will hyssop survive a UK winter?

Yes — hardy in most UK gardens (RHS H5), staying semi-evergreen through normal winters. Main failure mode: cold WET winters on heavy soils rot the crown. Prevention: plant on well-drained or gritty soil; on clay, plant on a raised mound or grow in a pot. Established plants survive temperatures down to about -15°C in dry conditions. The above-ground growth may lose some leaves in a hard winter but the plant returns from the woody base in spring.

What does hyssop taste like?

Strong, minty, slightly bitter, with eucalyptus and camphor edges. It's a polarising flavour — wonderful in small quantities in stuffings, game dishes, and herbal liqueurs (Chartreuse, Bénédictine); overpowering in most modern cooking. Most UK home cooks find hyssop too strong for everyday use. Try it once in a stuffing for roast lamb or game bird before deciding whether to grow it for the kitchen. As a bee plant and ornamental it earns its place even if you never use it culinarily.

When does hyssop flower?

July to September, with peak flowering in late July and August. The deep blue (or pink/white) spike flowers attract enormous numbers of bees, hoverflies, and butterflies — hyssop is one of the top UK garden plants for pollinator diversity in high summer. Each spike produces flowers for 4–6 weeks; the whole plant flowers continuously for 2 months. For maximum flowering: hard-prune in April, don't feed, and don't deadhead during the flowering period (it slows production).

Can I grow hyssop in a pot?

Yes — and on heavy soils, it's the better option. A 25 cm pot of peat-free compost mixed 30% with horticultural grit, in full sun. The pot advantage: perfect drainage protects against winter crown rot. Don't feed. Water only when the surface is bone dry. Refresh top compost annually. Pot hyssop lives 4–5 years and works well as a patio bee plant. A 30 cm pot with three young plants of mixed colours makes a striking ornamental container.

Is hyssop good for bees?

Outstanding — one of the top 10 UK garden plants for pollinator diversity. The small two-lipped flowers are accessible to bumblebees, honeybees, solitary bees, hoverflies, and butterflies. The dense spike form means each plant has hundreds of small flowers open at once during July–August. Beekeepers sometimes plant hyssop near hives for the strong nectar flow. A hyssop bed in flower is a constant buzz of bee activity. The plant's traditional medicinal reputation pales next to its modern wildlife garden value.

Hyssopus officinalis

Plant hyssop from a young plant in spring, in full sun in well-drained gritty soil — it's a hardy Mediterranean semi-shrubby perennial that gives narrow grey-green leaves and dense spires of small two-lipped flowers in deep blue (or pink/white) from July to September. Hyssop is hardy (RHS H5) and stays semi-evergreen through normal UK winters; the dense low (40–60 cm) habit makes it useful as a low formal hedge in traditional knot gardens. Outstanding for bees — one of the top UK garden plants for honey-bee and bumblebee diversity, working the flowers constantly through high summer. The strong minty-bitter flavour is too pungent for most modern UK kitchens but historically used in stuffings, monastic liqueurs (Chartreuse), and herbal medicine. Cut hard back in spring (April) to keep compact. Replace every 4–5 years.
