Bee orchid numbers this year are much lower than last year, probably due to the very dry March in 2024 followed by a dry April. March and April are when plants make up the tuber for the next year and if it isn't large enough it wont flower. This year has been ec=ven dryer in March and April so expect a poor year in 2026 for Bee Orchids.
There are however bee orchids around on the Island and this week is perfect for sharing some lovely photos.
Photos 1 and 2 show a large plant at the Chesil Nature reserve growing on a sand bank.
Photos 3 and 4 are a colony we have not found previously on a old quarried ledge on the cliffs just down from our nursery. The very short turf indicated the dry thin soil a few cm thick ontop of the limestone.
It has also been great to see a new colony at the back of a new housing development where quarry waste has been spread without topsoil giving a perfect environment for local wildflowers including orchids.
Every summer is marked in our cloud forest greenhouse by the dramatic flowering of Dendrobium victoria regina.
This stunning orchid from the mountains of the Philippines has always been a favourite in our collection and, as I have mentioned before, we have two lovely clones. The first with very large purple flowers (photos 1 and 2) and a lighter blue smaller flowered but very vigorous clone (photo 3)
We have more seedling of the cross between the two in the lab and available soon.
Dendrobium victoria regina is a cool growing epiphyte, and in the wild grows on moss covered trees in consistent moisture all year round.
In cultivation we grow plants hanging in our cloud forest greenhouse (winter minimum 12C) and watered daily, or twice daily in warm weather.
The BBC spent plently of time filming these gorgeous flowers last week at the nursery and we are hoping that they will still be at their best for the Gardeners World Live Show at the NEC in the second week of June.
In contrast to Yesterday's diminutive bulbophyllum today's species has dramatic 14cm flowers in bright red.
We originally kept this species under the name Cirrhopetalum collettii as the Bulbophyllums with their flowers produced in a ring were previously known as Cirrhopetalums. To add to the confusion Bulbophyllum collettii is a totally different species so it is great to have its identity sorted - for all our names we follow Kew's Plants of the World Online which is a great place to search for plant names as well as giving access to lots of herbarium sheet images to check plants against.
Bulbophyllum wendlandianum is native to Laos, Myanmar and Thailand but is not a species we have seen in travels to South East Asia. It is reported from hot lowland forests right up to 2000m altitude and we have found plants in cultivation to be tolerant of a wide range of conditions. Our plants grow high in our Cloud forest greenhouse and the high light conditions here induce plants to flower very freely (as you can see from the photographs). Flowers only last about a week but for that week plants look amazing. Plants are compact making this a great orchid to grow.
As regulars will know we love miniature orchids and one we haven't featured is this delightful mini-miniature bulbophyllum. (The pot in the photo is 6cm diameter)
Bulbophyllum shweliense is native to South East Asia and Southern China and although not recorded in Laos is a species we probably found there in forests around Paksong (plants were not in flower so definitive identifation wasn't possible).
The species has a lovely habit of crawling around on its host branches with its little bulbs separated by a thin rhizome. The flowers come from the rhyzome and are only a few milimetres across but are really cute.
We grow the species mounted and in little pots and have recently split our stock plant so we will have plants available soon.
Bulbophyllum shweliense is reported from hot lowland forests right up to 2500m altitude and so should grow warm or cool. We grow our plants in our indoor growing cabinets (min 17C) where they flourish.
BBC filming for Gardeners World went very well (more details here) and we will be included in the program going out on Friday June 13th.
Gardeners world will feature some of our amazing Masdevallia species including Masdevallia venustum which is another of the very bright hummingbird pollinated species in Masdevallia subsection coccinea.
Masdevallia venusta is a compact plant that produces really large flowers on relaxed or pendulous flower stems. The evolutionary advantage of these stems is that flowers in nature are presented away from the plant in fresh air giving easy access to the pollinating bird.
The dramatic flowers are orange with scarlet stripes a real beauty. The species was originally found in Northern Peru in wet forests at around 2500m altitude but it has not been found again since its original collection. This means that all plants in cultivation have come from the original collection in the early 1900's. The fact that plants do still exist suggest that the species is quite straight forward in cultivation and also encourages us to pollinate our plants to help make more plants available into the future.
If anyone bumps into the species in the forests of Northern Peru do let us know.
We are delighted that our greenhouses are full of flowers this week as we have BBC Gardeners World cameras arriving on Friday. The most flowery species is our wonderful old plant of Dendrobium densiflorum.
As you can see this orchid completely fill part of the roof of our Cloud Forest Greenhouse and looks remarkably similar to the plants we have seen in Sikkim (photo 3)
In Sikkim we have found the species growing at around 1000m where it lives as an epiphyte generally in tall semi-evergreen trees with little moss. The high end of its range overlaps the lower end of Dendrobium nobile’s range and we have seen both species flowering together in late spring just as they do in our greenhouse.
We grow out plants mounted on large sticks with heavy watering in the summer.
The natural habitat of the species is a little warmer than that of most of our orchids in our cloud forests greenhouse (min 12C), and a lot warmer than our Himalayan greenhouse (min 7C) (Our Cymbidiums and Coelogynes live at least 1000m higher up than Dendrobium densiflorum in the Sikkim forests) So to provide ideal conditions for Dendrobium densiflorum we hang our plant high in the roof of the greenhouse where it clearly enjoys the extra warmth and light.
In its habitat the summers are warm and wet and the winters cooler and dryer but not to dry as shown by the moss on its host tree.
Plants are very long lived and flower from older pseudobulbs so patience is required to grow a specimen – but it is well worth it as shown by the lovely specimen in the forests of Sikkim and in our greenhouse. Our plant came from a wonderful old orchid friend John House and it is nice to remember him each spring when it flowers.
The species, which has been a firm favourite since Victorian times, has thick waxy flowers that are long lasting if kept dry. If you are into scented plants, you just must grow this species. It is a real shame that we can’t provide scent with our photos here – you just have to come to the show this weekend.
Bifrenaria harrisoniae is native to the Mata Atlantica, Brazil, and in 2000 our expedition came across it growing on a bare granite mountain side West of Nova Friburgo.
As the photo (photo 3) shows, plants are growing in full sun with their roots holding firmly to the rock and very little around the plant to retain moisture. This rock was dry in the winter when we visited but would be running with water for much of the wet summer season. After seeing the plant in the wild we adjusted our growing of the species to give more light but keep cool temperatures (the altitude was around 1000m) and we grow plants in the brightests part of our Himalayas greenhouse (minimum 7C)
The habitat also sheds light on the why the species choses April both to flower and release seed. In April the climate here is still dry meaning that flowers will remain undamaged until pollinated and seed released now will be able to blow across the dry habitat. In a months time there will be heavy rains, providing water for the new growths, the maturing seed pods and the germinating seedlings.
Epidendrum parkinsonianum is a species we are particularly fond of, since finding it in the volcanic mountains of Costa Rica.
The large white flowers are pollinated by large Hawk Moths and the flowers are fragrant at night.
In Costa Rica we found the species in the forests clothing the Poas volcano, where it grows at around 1200m altitude, hanging on the trunks and main branches of trees near rivers. (see photo below) The forest here is cool and wet, and the plants growth habit means that it grown in quite deep shade.
This habitat surprised us as we had previously assumed from the thick terete leaves that it needs a dry bright environment. Growing the plant into cool shady conditions in our Cloud Forests greenhouse (minimum 12C) seems to suit it very well.
Today we have another orchid that has changed its name.
This lovely orchid came to our collection as Epigenium cybidioides but along with all epiginium species has moved to Dendrobium as a result of molecular studies.
Cymbidioides refers to the similarity between the flowers of this species and some Cymbidium species although to my eye the flowers look much more like Coelogynes.
Dendobium cymbidiodes is nartive to the islands of Indonesia; Java, Sumatra and the Sunda Islandswhere it is reportedly found in cool moss forests from 2200-2800m altiude. We replicat this habitat by growing plants in our 'Himalayas' greenhouse (min 7C) with lots of water in thje growing season. We have found that plants enjoy bright light especially in the winter which helps to encourage heavy flowering in April and May.
Gongoras are very rewarding orchids to grow with unusual attractive flowers and exotic scents. Today we have the first flowering of seedlings of Gongora grossa (first three photos) which has a really spicy scent that reminds me of 1970's aftershave and divides people into those who love it and those who really don't.
The plant that I pollinated to produce the seed was then called Gonogora nigropunctata (photo below) in reference to the dark spotting and it has taken six years for the first seedling to flower. As can be seen from the parent plant our little seedling will grow longer flower spikes as it matures.
Gongora nigropunctata is now considered synonymous with Gongors grossa and Gongora grossa is found in Venezuela, Colombia, Ecuador and Peru and so is quite a variable species.
The natural habitat is warm, wet, evergreen, lowland forest in shade. To replicate this environment we grow plants indoors in our IKEA cases with a minimum temperature of 17C a little away from the growlights. Although the flower spikes become dramatically pendulous they start by growing upwards and so plants can be grown in pots as well as baskets.
As you can see from our seedling, the species flowers when quite small but will make a lovely specimen over time - or if you have limited space plants can be split and kept small.
taking the opportuntiy to wish everyone Happy Easter we have three small growing masdevallias in flower that live next to each other, so a a special treat we are featuring all three.
The Masdevallias, from left to right, are Masdevallia triangularis, Masdevallia decumana and Masdevallia nivea.
Masdevallia traingularis is a neat little plant with small plant (10cm leaves) with relatively large flowers 14cm from tip to tip) that are kind of triangular. Of course most masdevallias have flowers that are kind of triangular so I am not sure what encouraged English botanist John Lindley to single out this species in 1846!. The flowers have lovely red/orange spots and long, dark red tails. Masdevallia triangularis is a widespread South American species found from Venuzela to Peru and with such a wide distribution it is not surprising that the species is quite variable with colours from yellow through to dark orange.
Masdevallia decumana is Annies favourite orchid. It is a tiny 5cm plant with very large flowers. We find that the species prefers to be mounted, though can also be grown in a small pot. Masdevallia decumana is native to cloud forests in Ecuador and Peru from 1000-2500m.
Masdevallia nivea is intermediate in size between M. triangularis and M. decumanaand again makes a lovely neat little plant with giant flowers.
Masdevallia nivea is endemic to Colombia and found in cloud forests at around 2800m altitude.
We find that all of these Masdevallias enjoy our cloud forest greenhouse (Min 12C) where they are kept well watered all year (sprayed once or twice a day depending on the weather) and grown low down in the greenhouse in shade and cool.
The top of our greenhouse is Dendrobium aphyllum world this week. The wonderful pink and cream flowers look great against the blue of the sky and remind me of trips to Sikkim where the lowland forests are often full of this beautiful species. (photo 2 in morning sunshine in Sikkim)
Dendrobium aphyllum is a warm growing species and we have seen it in the Himalayas growing on trees from 200m to about 900m altitude. It also grows as a lithophyte on large boulders and cliffs. Here the forest is semi-deciduous (see photo 3) below so the plants get lots of light in the cooler winter months.
The species is very pendulous with long thin canes that grow with lush light green leaves during the very wet summer from May to September. Plants then drop all of the leaves and remain leafless until flowering. We grow the species in our cloudforest greenhouse growing high above our cool growing Masdevallias, keeping it really wet all summer and then bone dry from December to February when it loses its leaves. We hang it really high in the greenhouse where it is as warm and bright as possible.
The species flowers well as a small plant but over time can form a large clump as shown by this magnificent specimen. We have small plants flourishing that will be ready for sale in about a months time.
Today's orchid is delightfully sweet and very fragrant.
Coelogyne chinensis is native to Southern China and Vietnam and across South East Asia as far as Arunachal Pradesh, where it experience a wet summer monsoon and a cooler dryer winter when it flowers.
We have grown it both cool in our Cloud Forest Greenhouse (min 12C) and warm indoors. It grows well in both environments flowering in February when grown warm and in April when grown cool. We find that although the species grows and flowers in heavy shade it flowers much more profusely when grown in good light.
The species is semi deciduous and when grown cool and bright drops it leaves before flowering. Interestingly, in common with many deciduous species, Coelogyne chinensis has a spike on top of its pseudobulbs left when the leaves fall, presumably to deter herbivores.
The flower spikes emerge from the centre of emerging new growths and so we are now increasing watering for the growing season through to the end of September.
The second week in April is the always our time to make a pilgrimage to the Purbeck Coast in Dorset to find the Early spider Orchid
This wonderful species (that last week I likened to Gastrochilus retrocallus) is one of the UK's less common orchids but in its Dorset stronghold can easily bee found amongst the short turf near the coast path.
The plants are not large but when you get your eye in they are not hard to spot. For anyone wanting to find them for the first time the a walk along the coat path from Dancing Ledge (easily reached from the National Trust car park in Langton Matravers) towards Durlaston Head will guarantee lots of plants and they should be flowering for the next week or two.
This wonderful miniature orchid is a species we would never be without.
Gastrochilus retrocallus is endemic to Taiwan and is a vigorous little member of the Vanda family with relatively large flowers bourne on and off throughout the year in ones and twos on short pendulous spikes.
The natural habitat of the species is reported as open deciduous forest between 1000 and 2000m altitude which explains the extensive root system to cope with dry periods.
We grow the species mounted on cork bark in our Ikea growing cabinets (see photo below) with a minimum of 17C although it would grow cooler)
I am intrigues by the flower's resemblance to our native Early Spider Orchids which are now flowering on the Dorset coast (photo 4) and wonder if they have a similar pollination strategy.
The species has previously been called Haraella retrocala and Haraella odorata, the last of which references the lovely scent of the flowers.
