We , gardeners , are all intimate with the genus Nicotiana . While we may not know that was name for Jean Nicot , a French diplomat in 1559 . Mssr . Nicot first saw a tobacco plant curtly after it arrived in some plant life compendium made in South America a few years earlier . confident that is had medicative property , he represent the plant to the French queen , Catherine de Médicis , as a remedy for her headaches . on the face of it , her result endorsement ( which frankly might have been more of an habituation than anything else ) made Nicotiana tabacum quite notable . It did n’t take long for the famous baccy take hold of those who loved it , , and cultivation spread across Europe and shortly later , back to North America , where it was already a well - known drug and ceremonial smoke to indiginous folk .
I decided to trial a few new selections this year after reading about how honest-to-goodness selection were once far-flung conservatoire plant in the 19th century . This interested me , as I never thought of Nicotiana as a potted plant , at least as a conservatory plant . Older books often talked about estate gardeners grow private industrial plant to perfection for spring and summer display in glasshouses and conservatory ( think : Isabella Stewart Gardner Museum ) . You know , I love that sort of challenge .
After some ( well , great deal ) of research , I discover that the works was also recommended for civilization as a pot display plant in cold-blooded or nerveless greenhouse – so now I was interested .
A border of 5 foot tall nicotiana after my interesting trial that I conducted to test various cultural methods to see if I could get better results from what is typically a ho-hum flower.
Nicotiana was typically a works that I turn from seed only occasionally . I more likely would just buy a few plants from safe growers or nibble up a few 6 packs if the colouration matter to me . If I sowed from semen , it would be a more casual affaire , sprinkling a few seed ( always lightly , I know that much ) in a lot , pricking out and potting up later in spring for a few spots in the garden . They always seemed to execute well , but candidly , I could never say that I fussed with them or even followed any complex command other than what I already jazz ( bottom heat , bright igniter , and do n’t pop too early .
What get me attention in one Holy Writ was that the author suggested that I inseminate seeds in November or December for blooms in April . Of naturally , this was a British book , and was informing those who possess cold greenhouses in the UK who require other exhibit material , but hey – I had a inhuman greenhouse . While I live in New England ( not Old England ) , it should still work .
I take a few varieties to sow very early ( at least for me ) , in December . Since weak levels are low in wintertime here , and the greenhouse is too cold .
I selected a range of new and old Nicotiana varieties, some crosses and those with features I liked such as height or interesting colors.
‘ Night Flight ’ appealed to me because of it ’s size of it and promise 6′ altitude , something I tend to look at first as I care tall yearbook . It ’s was also order to have acute sweetness , which was so true that it surprised me many evenings , as I looked for “ what is that aroma ? ” believing that it was indeed a jasmine . I am seldom that horse around . ‘ Night Flight ’ is also unique from a performance perspective . It ’s truly night blooming , opening in the eve when it ’s extremely fragrant , and the flush also lift up at that time as if to give out more aroma . I would often reckon that they were wilting during the Clarence Shepard Day Jr. , and the lack of daytime fragrance often caught me off guard when I asked guest to smell out it at noon .
This is hybrid betweenNicotiana alataandNicotiana forgetiana . ‘Night Flight ’ was offered by Select Seeds , and it seems only by them , so perchance it ’s proprietary to them ?
I ’m a gull for brown prime , so I had to try a selection called N. ‘ Hot Chocolate ’ as well as N. ‘ Bronze Queen ’ . Both , selections that let in my famed , ego - seed green - flowered N. langsdorfii in their gene .
Nicotiana ‘Selected Night Flight’ were huge plants with flowers that became highly fragrant at dusk.
Another N. langsdorfii crosss called N. ‘ Starlight professional dancer ’ ( N. langsdorfii x N. alata ’ ) a white efflorescence motley with loads of bloom made my January inclination . N. alata itself , is often call ‘ jasmine tobacco ’ , so yeah – perfume was promised . N. alata itself is a prospicient - sentence favorite around here . ‘ Starlight Dancer ’ is a comparatively late unveiling , a hybrid from the Netherlands . It can grow up to 4 feet magniloquent so yes , height appeal to me .
I did supply at the last mo , two pop shorter - flowering metal money , strictly for beauty . The clear regal strain ‘ Perfume Deep Purple ’ , which is an AAS winner . ( N. x sanderae ) , and N. ‘ Lime Green ’ with exchangeable heritage . After all , I am not a prude . One must have simple , awesome stunner . These bloomed later as I sowed them in April and May , but they lasted until … hoarfrost .
I started these under light in the house . wayward to what many wintertime - sow folks believe , Nicotiana do not require any stratification or cold temperatures to sprout . They may re - sow or ego - sow , hold up a coarse wintertime , but they for certain do not want nor need feezing temperature . Seed will not germinate until the grunge temperatures reach 72 ° F or higher .
Nicotiana ‘Hot Chocolate’ delivered on the deep-brown color promise despite reviews I had read on-line. This was my absolute favorite nicotiana, perhaps of all time.
By December and later , January sow seedling issue within a week . I covered seed with a wakeful coating of fine vermiculite as soil can dry out in wintertime quicker , though seed sown outdoors will pullulate best if sprinkled on the surface . source are midget .
I knew that most species of Nicotiana look standardised when not in bloom . Any differences are pernicious and do n’t appear until the flora begin to constitute unfolding stems or bud . This means that you must label cum flats as it ’s easy to get confused . I discovered that I had to mark individual heap , as I grew the multifariousness and even then , I have to say that things got mixed up so I created a parking lot of confused , unmarked pots . If you ’re originate a few under Inner Light , this wo n’t be a problem if you keep individual pots set inside of another flat .
It is also worth note that nicotiana plants , peculiarly seedling but also young plant life have surprisingly brittle and clingy foliage that are gummy to the touch . The marijuana cigarette to one another and will rive or fracture easily if you do n’t take great attention when fork them . Another reason to sow seed thinly , and to repot when the seedling are still tiny . And think me , they are diminutive . I over - pot them , meaning that I leave alone out a 1/2 column inch wide seedling and set it with the tip of a works recording label into a 3 or 4 inch pot .
Nicotiana ‘Hot Chocolate’
Nicotianas are athirst works . too . I used both a balanced Osmocote , and a liquid fish emulsion weekly . As I often do , not only do I see at sometime books , I compare those with contemporary science and research . One of the best places to depend for information are on professional grower or culture sheet ( just Google Nicotiana Culture Sheet ) . I used those from Florinova , but most provide good basic entropy in regards to temperatures and fertilizer . Be prepared for these pdf ’s to evoke ridiculously high concentrations of fertilizer , which of line , I do n’t follow , but it ’s helpful to know if a species is sensible to magnesium or an teemingness of nitrogen . All too often I see unfounded recommendations on sites such as “ just use seaweed ” or “ Epsom salts will do the trick ” . fortunately , Nicotiana are n’t that fussy , and either a balanced feed ( Miracle Gro ) or even a Pisces photographic emulsion will work delicately . Pro ’s utilise a 20 - 10 - 20 .
Temperatures should be tender during germination ( 75 ° is ideal ) and 70 while growing one when immature , so I kept seed tray under light until mid - Mar . After that , 65 ° F is ideal and while nighttime temps dropped to 50 in the greenhouse by then , once transplant , all seedling were kept in the greenhouse . liter
Plants were all grown on in increasingly larger pots as soon as rootage started to emerge from the bottom . As spring advance , and the nursery became warmer and the days longer , plant bulge out to grow larger and faster . I wholly understand that not everyone has the sumptuousness to grow annuals in this means , but it does teach us that with care , some of even the most common annuals can excel if produce carefully at home , even if you start them under visible radiation in your service department or cellar and just seed them later .
Nicotiana ‘Starlight Dancer’, a hybrid between N. langsdorfii and the Jasmine tobacco. Fragrant and floriferous, this made my list for growing again with its abundant blooms. It would be a great moon garden plant.
Pot size of it was key to succeeder . I get a line that seedling must be transplanted untested , before they become too large ( before three brace of parting ) . If you want incredibly tall and stunning Nicotiana , invalidate permit roots touch the edge of their pot . I know this sounds crazy , but if you ’ve detect self - seeded plants in the garden , you could clearly see the difference . Once nicotiana become pot - restrain there is no recovery . Plants will be spindly and they ’ll that flower too too soon , on hopelessly short stalks . Unfortunately , that ’s what we typically find sell at retail , and no cutting back , pinching or spreading the roots will aid those recover to equalize the performance of those grow without root book binding . I kind - of knew that , but never really trust it .
I upgraded some to 8″ nursery stack , and other were keep in 6″ square plastic pots . A few of the ‘ Night Flight ’ variety though begin to meet the hope of 6 ft plants , so I propel them up to 12″ clay pots , one per pot – clear overkill , but they respond so well , that I started to move more plants into bigger pots .
I started to bunk out of room , but the results of moving plant up into larger sens did confirm what I had expect , and what the old books all apprize – that Nicotiana will sulkiness if kept pot recoil ( again , think about those nursery 6 inner circle where the ascendent ball is entirely white with beginning ) . Nicotiana are also sensitive to plant increment regulators , but I also know that commercial raiser could not possibly address with 4 foot marvellous seedling . We ’ve all seed nicotiana in - bloom at the garden center in 6 gang , often that ’s all we can find , but while they execute just fine , I recognize that ego seed ones were always good . I was nt all that surprised .
Seedlings were all sown in flats or 4″ pots, using sterile Pro Mix and a light 1/7 inch coating of fine vermiculite.
I did pinch a few back , which surprised me that it was advice in these old books , and while the last effect was nt as elegant as the first , marvelous exclusive base , the plant life that I did pinch did produce side shoot and many more blooms . I might purloin if I planned to set out plant life into a aggregated planting in a border , but I lean to like the lifelike look of unpinched .
intelligibly I grow too many , but the results were interesting . Most noticible were blooming size and overall plant life drug abuse in relation to pot size of it . All mintage and miscellanea bloomed weeks earlier on importantly short stems if they were continue in 2″ pots . The plant life that were in the largest kitty continued to form rosettes of gigantic folio for many weeks before they start out direct up their first main florescence theme . These stem turn did contact up to 6 metrical unit tall as promised , looking more like those self - seeded plant that would pop up up in my garden .
In the garden , these more ripe plant bloom extravagantly in June and former July , but they did peter out by the oddment of July . A few that were cut back did rebloom , but the effect was nt even close to that first bang of blooming . My later sown plants ( the purpleness and lime green ) bloomed well all summertime . In the end , I again point out that my self - seeded var. were still the most agressive and strong growers , but they did nt emerge until mid to late June , which tells me that I could sow alfresco as deep as the summertime solstice in June . All the plants that were start up in the glasshouse produced tremendous but former shows , but they all required staking and failed to go on after mid - summer .
Under bright lights set to 16 hours and warmth (72° F) seedlings that were sown February 2nd grew quickly and were ready to transplant once they grew their second and third pair of leaves by March 3rd.
All of this tells me that we should n’t set out Nicotiana indoors at all unless we want early blooms . We should not use the winter sowing method as that is just speculative horticulture , but we could sow seeds in seed trays and pots in June , which is when they really want to germinate . These grow very quickly . I will do both , sow some under lights in January but primarily for early greenhouse color in April and May , and for some striking outdoor beds in June and former July . My 2nd crop will be sown alfresco in June , that will exchange those that are fading .
I will add that all of my methods this class were usable and produce far better results than any plants that I bought at garden center or nursery . The only exception are those that I corrupt from a few specialty agriculturist ( like Bunker Farm in Vermont or Walker Farm Stand also in Vermont ) who truly know what they are doing as they trade small seedlings in larger pots or 6 - face pack . mayhap you have a cultivator like that near you , or better yet , dictate some seed now and experiment yourself !
By May , I could tell that pot size and rankness strike public presentation . The seedling that were transplant into stock 2.5″ modules , pots or six packs were all start out to bloom even though they were less than a foot tall . The seedlings transplanted into 3″ pots were n’t much better , but had foliage that look salubrious . Plants in 6″ heap ( one per mickle ) looked far well , were at least 4 foot magniloquent and were not even beginning to form flower bud yet . plant in 12″ wad had leaf as heavy as cabbage , and were form central stalks as thick as 1″ in diameter . I ’ve never seen such a deviation with an yearly .
Young plants were provided the luxury of large, single pots to see if pot size would affect quality.

Various sizes of pots were used. These are deep 8 inch root trainer pots that are 4″ in diameter.
The plants set into 4″ deep pots quickly outgrew their pots, requiring an upgrade to 6″ or 12″ combo pots so that roots would experience no constriction, allowing plants to reach their optimum size. Plants also didn’t ‘bolt’ into bloom in larger pots, waiting more than a month longer before starting to send up florals stalks. Seedlings from the same seed tray that remained in 2″ pots were often already in bloom by then.
Nicotiana ‘Starlight Dancer’ set into 6″ pots grew even quicker, with larger foliage and maximum root growth in comparison to other seedlings from the same seed tray that were being grown on in 2.5″ cells, which were significantly smaller and weaker.
All of these seedlings were started at the same time (Feb.2) but by May 14 matured and started blooming at very different heights.
Newly set out giant plants along the greenhouse path.
Smaller plants, those grown on in 2.5 inch pots were smaller overall, reaching about 2.5 feet in the garden. The still bloomed well but were significantly less showy that the 6 foot giants that were grown in 12 and 14″ pots.
Plants from the very same seed pot that were bring grown in 2.5″ deep cells were substantially smaller and weaker. These are closer to the quality and size one might find at a garden center. Final size once planted out was half the height of those grown without any root constriction.
The same seedlings that were planted in 10″ and 12″ pots (recycled nursery pots) were the largest. Clearly when roots are allowed to grow without any interference the plants do indeed grow much larger. This was the method used by estate gardeners a century ago. Single clay pots, spaced out on greenhouse benches, the giant plants were gorgeous.
The largest plants were eventually moved outdoors and planted along the greenhouse path. Not the ideal site, I found that plants were still too brittle as they had grown underclass for too long, so bamboo stakes were required (plus terriers like to rub their backs along the boxwood hedge. These were still spectacular while in bloom, taller than I was.
The greenhouse walk had never looked so good, and just in time for our Garden Conservancy Open Day’s tour..
Nicotiana ‘Perfume Mix; from Harris seeds also performed well, and the color palette worked nicely in the perennial border I call the Painter’s Garden”
Beauty in the perennial border a full month earlier than a typical display which allowed for some interesting combinations.
