Garden Highlights

As the seasons change different plants take precedence within the Garden creating a presence or a feature all of their own, either because of their great beauty or abundance, or simply because of the interest they generate amongst our visitors and gardeners alike!

However, the Garden provides many layers of interest with some of our rarest, most impressive and unique plants taking a little more effort to find. Read our monthly ‘Garden Highlights’ newsletter written by volunteer Colin Pope for a guided tour of our lesser-spotted friends of the plant world.


Amongst the 6,000 species of plants grown here at VBG, some are particularly worthy of attention due to their rarity, prolificacy, diversity or variety. We call them our ‘Rock Star’ plants.


Flowering: May – June

The firework display of giant Echiums is one of the best known and loved features of Ventnor Botanic Garden. All varieties come from the laurel forests on the Canary Isles and Madeira. The one most often seen in gardens is Echium pininana, originally from La Palma. Other species are also grown here and cross with one another freely producing a whole range of perplexing hybrids. One species which is very distinctive is the true blue Echium gentianoides from La Palma, which has large sky-blue flowers and smooth, grey-green leaves.


Flowering: All year

Red Hot Pokers or Kniphofia are one of the star plants of the Garden with their luxuriant clumps of foliage and large showy red or yellow spikes of flowers. In the wild, most of them come from South Africa. In the Garden we have a nationally renowned collection of Kniphofia including some, such as the true Kniphofia bruceae, which are endangered in the wild. There is usually at least one clump of red hot pokers flowering somewhere in the Garden in any month of the year. The best place to see them is in the South African Terrace.


Flowering: May – July

Another plant to look out for around the Garden are the very spiky leaved Puyas. This is one of the larger flowering Puya from the high latitudes of northern South America. With flower spikes up to 3m high, each flower spike is constructed of smaller branches of flowers, the ends of which are bare to allow birds to perch on them so they can drink the nectar inside. Pollination is carried out by the birds. Ventnor Botanic Garden has the National Collection of half-hardy and hardy Puya, comprising over 20 species in 77 accessions. The VBG logo is a close up image of a single Puya flower.


Flowering: August

The plant of the moment in August is the African Corn Lily or Agapanthus. There is a range of spectacularly showy species, hybrids and cultivars flowering throughout the Garden in various shades of blue and white. Many of ours are the more tender evergreen forms which originate principally from areas with winter or year round rainfall, such as the East and West Cape. Agapanthus is a plant considered to have both magical and medicinal properties by some native Africans. Here in the Gardens the forms known as ‘Ventnor Hybrid’ and others grow freely from seed and are starting to become invasive.

Ventnor Botanic Garden has one of the best collections of rare half-hardy trees and shrubs in the UK that grow in the warm and virtually frost free climate of the Undercliff. Some of these are the largest recorded specimens of their type and earn themselves the title of ‘UK Champion Trees’. Enjoy our new Champion Tree trail by picking up a guide at our admission desk…perfect for exploring the garden all year round.


Magnolia campbellii were discovered in the Himalayas and brought back to the UK during the 19th century. They were destined to change the face of British gardens forever. The tree arrived along with an avalanche of new introductions brought to the British Isles in 1868 by Joseph Hooker junior who succeeded his father as Director of Kew Gardens. Having been named by Hooker in honour of Dr. Archibald Campbell, Political Resident at Darjeeling, India, plants were quickly dispatched to the burgeoning estates in the milder Gulf Stream washed climes of Cornwall, Ireland and Scotland. Magnolia campbellii is a slow growing tree often needing more than 30 years to flower, but when they did they became sensations in the horticultural world. Their blooms graced shows of the Royal Horticultural Society and they became forefathers and mothers of graceful and beautiful cultivars, themselves named in honour of the estate owners whose staff bred them.

As large estates diminished following the first World War new homes for tree Magnolias were in short supply in their preferred mild locations. Gardens generally have progressively shrunk, thus there have been diminishing prospects for new plantings for these fascinating giants. Today, the Victorian introductions are fair comparators to their kin in the wild; they have become very large trees. Think of the stature of the London Plane and you will have an idea of how large they can become. On visiting these behemoths one is confronted with a huge trunk, the flowers held in excess of thirty or forty feet above the ground.

The Maritime climate is very suited to the large Magnolia, in Britain they flower early in the year at a time when frost still reigns supreme, and will turn newly open blooms brown in bright morning sunlight. Therefore the prospects of a slightly east facing garden with salt laden winds – on a shallow alkaline soil to boot – are not good for these trees. Certainly Sir Harold Hillier, who himself had a M. campbellii from the Alba Group named after him, did not see Ventnor as a site for them. Fortunately his successor, Simon Goodenough, saw things differently. He planted a small group in a sheltered position which offered itself as available following the great autumn clear-out afforded by the Great Storm of 1987. These trees left juvenility early in their lives and began flowering in the late 1990s.

We have been recording the flowering times of these Magnolias diligently ever since and it has been possible to see patterns emerging in relation to the type of winter we experience. A “usual” winter at VBG, where we have a mild start to the winter with a short cold snap around Christmas sees the first white M. campbellii var alba open in the first fortnight in January, with the redder cultivars opening two or three weeks later. Recent colder winters have pushed the first opening back into February. Our coldest winter for 30 years saw them open in March in 2010. Prior to this year the most interesting so far has been a pre-Christmas flowering in 2011 which followed an autumn where the temperature never went below 5ºC, but these early blooms where destroyed when a low pressure sat over Spain and pulled arctic cold down over us in February. This caused the Magnolias to start all over, but not until the first week of March. In 2016, following an Autumn where no frosts were recorded even on the Mainland, the Magnolias began to open on Christmas Eve and continued unchecked into full bloom from then onwards into January. In 2017 the Magnolias have begun to bloom on 5th February, quite late despite the mild winter.

In 2013 snow was recorded for the second time in 30 years at VBG, on 18 January, and endured for one day.  Two air frosts were recorded for the month, neither persisted through the following day.

The 2013/14 winter proved to be the mildest, wettest and windiest winter in living memory. December 2015 has been the mildest since the mid 19th Century. the winter of 2016/17 has been mild too, though some ground frosts were recorded and snow laid (mometarily) in January in Ventnor. As of 6th January 2017 we’ve not had an air frost for over four years, the last recorded on 18th January 2013.

In 2014 our first M. campbellii var alba opened on 6th February.

In 2015 our first M. campbellii var alba opened on 9th January.

In 2016 our first M. campbelli var alba opened before the end of the year on 24th December.

In 2017 our first M. campbellii var alba opened on 5th February.
