Hyssop

Hyssopus officinalis
A compact, semi-woody aromatic herb of the mint family with narrow, dark-green leaves and dense spikes of deep-blue (occasionally pink or white) flowers from midsummer onward. A classic cottage- and knot-garden plant, hyssop is one of the very best bee and butterfly plants in the herb border, drawing honey bees, solitary bees, and nectaring butterflies to its blue flower spikes. It is also a traditional culinary and medicinal herb: the leaves and flowers carry a strong, bitter, minty-camphor flavour used sparingly in cooking and as a flavouring in liqueurs (it is one of the herbs in Chartreuse). Long grown as Hyssopus officinalis, its accepted botanical name is now Dracocephalum officinale, though it remains universally known and sold under the familiar Hyssopus name. It is native to southern Europe and the Mediterranean across to central Asia (POWO, Kew), and carries that origin into the garden: it is easy, drought-tolerant, and sun-loving, asking only full sun and sharp drainage, and it gets woody and straggly unless clipped after flowering to keep it neat.

Breeding compatibility is not the gardener's concern for this aromatic ornamental herb; it is grown for its foliage, flowers, and pollinator value, not for fruit or seed-set.

Catnip (Nepeta cataria) - dense terminal spikes of small white flowers with purple/pink-spotted lower lips, toothed, downy grey-green mint-like (scalloped, heart-shaped) leaves, upright bushy aromatic herbaceous habit with multiple flowering shoots.
Nepeta cataria
Catnip
The true catnip: a bushy, aromatic, grey-green herbaceous perennial herb with toothed, downy, mint-like leaves and summer spikes of small white, purple-spotted flowers. POWO (Kew) gives its native range as across Europe and Asia, and it has naturalised worldwide. Its leaves carry nepetalactone, a powerful euphoric attractant for cats - roughly two-thirds of cats respond by rolling, rubbing, and chewing - so expect neighbourhood cats to flatten it; the same compound has documented repellent activity against mosquitoes and some insect pests. It is a tough, drought-tolerant, easy herb that self-seeds and can spread and flop, so cut it back hard after flowering for a fresh, tidier flush. It is hardy across USDA zones 3a-9b. RHS lists Nepeta cataria as a hardy aromatic herb for bees and culinary/herbal use and rates it fully hardy (H7). It is a traditional human herb too - catnip tea is a mild, calming infusion and the young leaves have culinary use - and a good bee and pollinator plant. Note this is the species catnip (Nepeta cataria), distinct from the sterile ornamental catmint hybrid Nepeta x faassenii.

Calendula officinalis
Calendula (pot marigold)
An Old World cottage-garden annual grown for daisy- to chrysanthemum-like flowerheads (3 to 4 inches across) in bright yellow through deep orange, often with a contrasting darker center disk. In cool climates it blooms over a long summer-to-fall window; in hot summers it tends to languish and may need a midseason cutback to rebloom. The somewhat bitter flowers and lance-shaped aromatic leaves are edible, and the petals lend color to soups, rice, and baked goods.

Greek mountain tea (Sideritis syriaca) - woolly, felted silver-grey foliage forming basal rosettes and clothing the stiff upright stems, erect, unbranched flowering stems characteristic of the plant's habit, developing woolly flower spikes (felted bracts) at the stem tips, growing in a dry rocky mediterranean setting.
Sideritis syriaca
Greek mountain tea
A low, drought-loving Mediterranean herb grown for its woolly silver-grey rosettes of soft, felted leaves and its stiff summer spikes of small, soft-yellow flowers cupped in densely woolly bracts - the plant known as Greek mountain tea or ironwort. It is a tough alpine and rock-garden subject that wants hot, dry, very sharply drained ground and full sun, and rots in wet or rich soil; it is only borderline hardy. POWO (Kew) records Sideritis syriaca as native to the eastern Mediterranean - Crete, the Levant, and Türkiye. The dried leaves and flower spikes make the traditional caffeine-free Greek herbal infusion long valued as a folk remedy for colds and coughs, so it is parts-edible as a tea but is grown as a herb rather than a food crop. The soft-yellow summer spikes are a good bee plant.
