Growing Bananas in the UK is it just a pipe dream? Or is it reality?
(We are often asked if you can grow edible bananas from seed - sorry this is not possible, only ornamental Bananas have fruit full of seeds and edible banana fruit is seedless)
Musa Sikkimensis in their Second Year from Seed How many of us have dreamed to grow a banana plant at home after visiting an exotic location on holiday? With their giant tropical leaves and superb architectural structure they perfectly represent our vision of a tropical paradise. The good news is that you can grow them at home, either outside as hardy perennials, as summer bedding raised from seed or suckers, as indoor house plants or as superb ornamental conservatory plants. You can now even grow your own edible fruit with the right dwarf variety! Outdoor Root Hardy Banana - Musa Basjoo |
Musa Basjoo For the entrepreneurial enthusiast, more extreme protection methods using straw bale structures or chimney liner concrete tubes filled with straw is worth a try. These structures are placed around the main stem up to about 6' protecting it from frost during winter. The subsequent re-growth out of the top of the trunk next spring can then reach maturity after two to three years, flowering when 8' to 10' high. The fruit is unlikely to ripen though and even if it does, it is not edible and full of seeds. Basjoo is only available in plant form from nurseries or by mail-order and I have never seen viable seed offered for sale. In late spring new shoots emerge from the ground and will grow on to make a clump of plants attaining about 5' by the end of the summer. Be aware though that treated this way it will not flower or fruit in the UK. |
Outdoor Root Hardy Bananas - Alternatives
A more attractive option has been the arrival of two other (maybe three) root hardy alternatives over the last few years. The first, from the foot hills of the Sikkim region of the Himalayas, is Musa Sikkimensis, presumably found by Hooker during his Sikkim explorations after who it is sometimes named. It is readily grown from seed unlike Basjoo, and is a more robust larger plant capable of reaching 10ft in its second year if over wintered in a frost free greenhouse or conservatory. We have had some success with Musa itinerans Yunnan, Sikkimensis Daj Giant, Helens Hybrid, and Musa thomsonii but these have only come through with mild winters. |
Musa Yunnan In my own trials Musa Yunnan grows well in our cool summer climate but winter hardiness has still to be proved. I have not seen many plants for sale but seed is available from a couple of sources. The last purportedly root hardy banana is not strictly a banana at all but a closely related species called Musella Lasiocarpa. You can see from the picture that it carries a large yellow flower head on top of 3ft stems in its second to third year from seed or micro propagation. A very ornamental plant with Banana like leaves but prone to red spider infection if kept indoors in a dry atmosphere. |
Musella Lassiocarpa What about Banana's just raised for Summer Bedding? Ensete maurelii My favourite Banana though for shear visual impact is Musa Ensete Maurelii, this grows just like the ordinary Ensete but with amazing huge blood flushed leaves and trunk. I was amazed seeing these plants in Florida though where they hardly show any colouring with predominantly green leaves. In the UK when planted outside, the combination of high summer light levels and our cool conditions maximises the red hues. The one in the picture taken last year was two years old reaching 8ft in this it's second year! During a summer heat wave (I think we had one last year?) I noticed that the colour faded slightly as the green took over but the red quickly came back again as the summer temperature returned to normal. 2 Year old Musa Ensette Ventricosum from seed shown opposite 2 year old Ensette Maurelii from one of our sale plants shown below |
The Ornamental Ensete Species Another excellent alternative is to consider the Musa Ensete species sometimes listed as just Ensete within the Musacea family and not as a true Musa. These are plants widely grown in Africa as an important food crop (in particular Abyssinia from where it gets its name as the Abyssinian Banana). However it is not grown for the fruit as you might expect, but for the starchy pseudo stem and corm like root. They take about 5 to 7 years to reach maturity in their native habitat, reaching giant proportions 30ft tall with trunks up to 2ft across and massive 15ft leaves up to 3ft wide. For the UK garden it is easily raised from the large marble sized seeds making attractive bedding plants with their large green leaves and red tinged midrib. It does not produce much of a trunk in height even if kept for about three years over wintered in a greenhouse. The one in the picture was three years old about 12ft tall and too large to bring in under cover for a fourth season. A stunning plant if grown well but very easy to raise, tough, forgiving and responding admirably to a rich compost and buckets of water. |
Rajapuri Chimera |
Variegated Banana Plants
I ought to mention one other ornamental Banana, really sort after but nigh on impossible to obtain, which is the Hawaiian Ae-Ae a green and white variegated leaf form that has eluded micro propagation specialist to mass produce for at least 10 years. I am told that this Banana is also susceptible to reverting back to all green or pure white as the soil ph varies but we have never seen that happen. We do have small quantities available grown on from suckers but these can be expensive. This fabulous banana is picky about the right conditions but not as difficult as Google searches suggest. The compost needs to have 30% vermiculite mixed in and we add long term fertiliser as well as trace elements to the mix. Heat is the problem and if you do not have 15C to 18C as a minimum winter night time temperature it will easily rot at the roots especially with too much water. Alternatively smaller plants can be kept in slightly cooler temperatures placed on a heat mat set to 28C to 30C. You could also try a short heating cable wrapped around the pot but air temperatures should not drop below 10c to 12c on the coldest nights.
Musa AeAe We also have a really attractive chimera of Musa Rajapuri with variegated leaves that has an exciting potential but the plant is only availability through suckers which is very limited like Musa Ae-Ae and it will not come true from micro propagation. We only have limited numbers of these plants for sale unfortunately. |
Fruiting Banana plants If you insist on trying a fruiting banana, then Dwarf Orinoco or Rajapuri are the hardiest fruiting bananas that also make a attractive summer bedding alternative. The plants thrive in our cool summers and is easy to over winter in a cool greenhouse. Rajapuri is heavier leaved and more like Cavendishi in habit with a white bloom on the trunk and underneath the leaves. This has been used by Parks Departments as bedding for a number of years. Dwarf Orinoco is a bit more slender and both will fruit with the tops of the pseudostem reaching 6ft to 8ft, although it may take quite a few years to achieve the fruiting stage depending on the conditions.

Cavendishi Types
We have three alternative verities of the less hardy Cavendishii types all which make excellent house plants with true fruiting potential if you have the space. Anyone visiting Cyprus will have seen the fields of banana plants and these are all Dwarf Cavensdishi that bears a smaller sweet fruit on plants attaining 8ft. Should you have a high ceiling conservatory or similar suitable heated environment it is worth a try. Most small banana plants offered for sale in garden centres are forms of the Cavendishi showing the typical maroon blotch on young leaves. To fruit it needs a large muck bucket sized pot with lots of manure and water and about a three to four years wait depending on the growing temperature. It can be done, I did it years ago but mine was by then crushed against our conservatory roof! The problem with these is that you really need a minimum of 18C night and day during the winter to be successful. The best news is that new dwarf cultivars are arriving, for those of us with limited heated space. We have two types both are super dwarf forms derived from a Cavendishi parent and of similar habit. They make excellent house plants rarely exceeding 4 ft and fruiting at that size with medium to large edible bananas on small hands. The Super Dwarf looks just like a stunted Cavendishi with broad leaves exhibiting some maroon blotching on new leaves with a stout stem. The Hi Colour Mini we also supply is a variety bred for improved maroon colouring on the leaves making it an attractive foliage plant coupled with a dwarf fruiting habit.
Cavendishi Super Dwarf |
Ornamental Bananas Musa Velutina easily raised from seed bears flowers and "pink" bananas on two year old 4ft plants. The species have slender green leaves and are hardier than most people think with over wintering in a slightly heated greenhouse an easy option. It quickly produces a nice clump forming habit but is best used as a pot plant placed on a sunny patio in summer
Musa Velutina Other ornamental types to try, if you have enough heat, all with attractive flowers on dwarf plants are the Musa ornata hybrids and easily raised from seed. We sell both purple and gold forms that you can try. They need cavendishii type warm conditions and develop into slender plants with a grey/white bloom to the reverse of the leaves and stems.

Ornamental Bananas Another stunning patio banana not so easily over wintered is Musa Zebrina. Again easily grown from seed but this plant has beautiful maroon mottled leaves and is used extensively as a pool side plant in warmer climates. A lovely conservatory plant as well but in my experience best grown afresh from seed each year when from a January sowing it will reach 4ft by the end of the season. It can also be used for tropical bedding planted out in a warm sheltered garden
