General Seeds N-O

​​

Narthecium californicum   7€/20seeds

Nemesia fruticans, wild form 3€/20seeds  SOLD OUT

Much simpler and smaller than your typical hangingbasket Nemesias, but this one will live forever by reseeding itself regularly in your gravel garden and it blends perfectly in a more natural garden. Requires summer water and will flower pretty much all year long.

​​

Nemophila maculata   3€/50seeds

​

Nemophila menziesii    3€/50seeds

Baby-blue eyes is a small but beautiful annual from western USA, forming a carpet of sky blue and white flowers in spring after sown in situ in autumn. It will self sow the following year after growing it. 

Nepeta amethystina 4€/20seeds   SOLD OUT

A drought tolerant small Nepeta, with attractive leaves with serrated margins creating small mounds that are topped with short spikes of light blue flowers in spring. Very drought tolerant.

Nepeta argolica 4€/20seeds

This Greek native herbaceous perennial species gets its name from Argos, but it can be found in a wide range mainly in the southern part of the country. In time, its stems will reach 1m high and are covered with greyish scented leaves and spikes of white flowers speckled with pink dots.

Nepeta curviflora 4€/20seeds.

Tough, xeric, early flowering, this amazing nepeta has upright stems (in full sun) up to 2 meters high. My substitute for Perovskia in my tough climate. 

Nepeta mussinii 3.50€/20seeds

This goes around but various names but it is an excellent low nepeta, suitable for groundcovering and with a weekly watering will look excellent even during prolonged droughts. 

Nepeta nepetella ssp. aragonensis 4€/20seeds

I’ve only grown this for a year but I’m in love already. Shiny silver leaves and pure white flowers all summer long, aromatic foliage, but most importantly it will produce all of this without summer water. 

Nepeta nuda 4€/20seeds

From higher altitudes in the Balkans, another herbaceous perennial Nepeta that flowers prolifically in summer with white to dark purple flowers.

​

Nepeta spruneri   4€/20seeds

Nepeta trachonitica 4€/20seeds  SOLD OUT

Very distinctive species from Spain, having few upright stems and fat spikes with magenta flowers. Even the seeds are extra fat.

​

Nepeta tuberosa  4€/20seeds  SOLD OUT

An Iberian species and quite different looking from most Nepetas you've come across. Upright stems clothed in tight leaves and a terminal inflorescence with purple flowers. 

Very striking. Will go into summer dormancy after it has finished flowering.

Nicotiana solanifolia 5€/20seeds

A big and bold perennial Nicotiana, obviously not very hardy as it grows in coastal situations in Chile but it should be ok in a Mediterranean climate. Big leaves and hanginginflorescences of green/yellow flowers. 

Nicotiana sp. From Brazil 3.50€/100seeds

An annual or short-lived perennial that gets up to 1m high and flowers continuously summer and autumn with long tubed flowers loved by moths as they will stay open up until the first morning hours (or longer if it is a cloudy day)

Nigella damascena 3€/50seeds

The perfect addition for a Mediterranean meadow. A winter growing annual with blue flowers and the typical inflated seed pods. 

​

Nigella gallica   4€/20seeds

​​

Nivenia corymbosa 8€/20seeds

No one argues the beauty of this very peculiar woody iris relatives from South Africa. Not the easiest thing to grow, so more for the 'adventurous' gardener. This will eventually form a 1 meter tall bush. Start in autumn.

​

Nivenia stenosiphon 8€/20seeds

Similar to the above but with a more compact habit and bigger flowers. Regardless, there's practically no Nivenia that is ugly.

​

Nolina bigelovii   4.50€/20seeds

​

Nolina microcarpa 3€/10seeds

You can't beat beargrasses for the grass like effect in the dry garden, but of course they are not related to grasses at all. With tough evergreen leaves and upright stems on mature plants with hundeds of cream flowers, they are as easy to grow as your neighborhood Agave amaerican (to which they are related). It takes a few years from seed, but we don't really have a wide variety of them in the Mediterranean so worth the effort. Sow seeds in late spring, in a sandy, well drained medium and do not overwater them during the first year. They germinate quite erratically, for me at least.

​

Nolina parryi   4.50€/20seeds

​

Nolina hibernica 'La Siberica' 4.50€/20seeds   SOLD OUT 

Much bigger and longer leaved compared to the one above, this beargrass will slowly develop in trunk. La Siberica is an area in Mexico from which it was collected by Cistus Nursery in case you were thinking Siberia...  Sow as N.microcarpa above.

 

Oenothera albicaulis   3.50€/20seeds

​

Oenothera argillicola 4€/20seeds

A species from the Appalachian mountains in the estern US. A biennial species that shoul be started in early spring to flower the next year.

​

Oenothera caespitosa 4€/20seeds

The desert evening primrose forms tight rosettes and big white flowers when it wakes up from its summer dormancy. 

Oenothera macrocarpa 3.50€/20seeds  SOLD OUT

I’m usually not a fan of Oenothera as many are way too weedy for my taste but this one is special. I will form tight clumps from its fat roots and provides low green/grey foliage and huge lemon-yellow flowers all summer long. Do not overwater.

​

Olneya tesota 4€/10seeds

Funnily, when I first encountered this desert tree I was in San Pedro de Atacama instead of its native land,the souther US and northen Mexico deserts. I was fascinated by its beautiful trunk, light shade and dangling silvery leaves. When I later saw it in full pink bloom in California I was just overwhelmed. The desert ironwood, can gradually become a big tree but it is attractive at all ages. Takes  drought but grows faster when its roots have established and reached some underground moisture, hence their preferance to washes and dry rivers in nature. Very easy from seed, just soak in warm water overnight and plant the next day. Within a week you'll have seedlings that most likely will leave longer than any of us.

​

Onobrychis ebenoides 3.50€/20seeds

A small subshrub with grey leaves and orange/pinkish flowers in late spring. Good for the gravel garden.

Ononis natrix 3.50€/20seeds

A small spiny shrub with yellow flowers in summer, without needing summer water – few plants can claim that. 

Onopordum illyricum 4€/10seeds

One of the giants in the thistle family, with huge cardoon like flowers on very upright stems. All parts of it are covered in spines.

Onosma frutescens  4€/10seeds

A small subshrub with pendant yellow and orange flowers. I can live more only with sharp drainage and no summer water.

Onosma graecum 4€/10seeds

An annual species, which should be started in the fall to flower in spring. Spiny like most Onosmas.

​

Opopanax hispidus   3€/20seeds

Origanum acutidens     5€/20seeds  

From Turkey, an Origanum in the O.dictamnus group, with glabrous leaves and big white bracts surrounding the flowers. For a well-drained spot, no summer water needed.

Origanum libanoticum 5€/20seeds  

Another on in the O.dictamnus group, with very peculiar downward pointing inflorescences, with a good pink color on the bracts. Very drought tolerant as well.

Origanum microphyllum 4€/20seeds

My favorite scent of all Origanum foliage, this tiny leaved beauty forms airy little shrublets with dangling purple flowers in the summer. In its homeland Crete, it is used as an infusion. 

​​

Origanum onites  3.50€/20seeds 

One of the origanum species used in cooking, this tough woody based perennial is also very attractive for its mounding habit, spicy scent and flat flowerheads with white flowers. Widespread in southern Italy, Greece and coastal Turkey. Very drought tolerant. Sow in spring or autumn.​

​

Origanum sipyleum 5€/20seeds  

A beautiful origano from the east Aegean coasts and Turkey, this has upright stems covered in hundreds of dangling flowers in summer.  The growth habit is similar to O.laevigatum. Can take exreme drought once established. Sown in spring or autumn without pretreatment.

 

Origanum virens  5€/20seeds

Origanum vulgare subsp. hirtum 3.50€/20seeds  SOLD OUT

Supposedly the best oregano for cooking (and Greek salads!) and I may be biased as a Greek but I agree. Grow it on the dry side with no added irrigation for the strongest of scents. Best collected and dried in full flower.

​

Oxytropis sericea 3.5€/20seeds

Related and similar looking to the herbaceous perennial Astragalus species, this perennial produces a profusion or white flowers in summer. It comes from high elevations of western US mountains, so your best chances are in a rock garden in the Mediterranean where its roots can enjoy cooler temperatures. Soak seeds in warm water overnight before sowingor mechanically scarify them.
