Ivydene Gardens Plants:
Bee Pollinated Plants for Hay Fever Sufferers List
for Plants above
72 inches (180 cms) in Height

See Wildflower Garden Use Page for other bee-pollinated or insect-pollinated list of plants.

If a plant is polinated by a bee, then it is not wind-pollinated. This means that the plants mentioned on this page and in the book "Garden Plants Valuable to Bees" (written by the International Bee Research Association) will be suitable for people who suffer from hay fever.

You can compare the flower colour of the bee-pollinated plants with all the other bee-pollinated plants (who have Plant Description Pages in this website) using the Bee-pollinated 12 colours of Bloom in each Month Gallery. There are also 218 additional bee-pollinated plants (who may not have any Plant Description Page in this website) in the 12 colours per month pages of the Bee-pollinated Index Gallery.

The importance of garden plants yielding nectar and pollen is that together they provide a continuous food supply - from willows and crocuses in early spring to ivy in late autumn. Colonies of bees need food through their active season , so that they can develop and rear new bees. This food supply used to be provided by pastures that came into flower before they were cut, by verges and hedgerows, and by abundant weeds. Nowadays the efficiency of agriculture has greatly reduced these resources for the bees.

The list for gardens exclude most crop plants, most fruits and all very invasive plants that are difficult to control.

It is designed for Britain, Ireland, Denmark, Belgium, France, Germany and the Netherlands.

"Ordinary garden soil" is pH 5-7 and contains some humus-forming material.

The report below details which plants in Greater San Francisco Bay Area Region of the USA were visited by each different bee family; and therefore will aid you in selection of plants that are bee-pollinated rather than wind-pollinated, besides the ones that I have listed in my table below:-

Landscape Noise Reduction

Road Noise, Airport Noise, Industrial Units and Railway Noise next to gardens is detrimental to humans living in those houses within those gardens. There are 4 methods commonly used for sound attenuation (the reduction of intensity of outdoor sounds before they reach the receiver) :-

• Sound Absorption. This method uses plants to entrap or absorb sound vibrations.
• Sound Deflection and Reflection. This method causes the noise to be bounced away from the recipient and sometimes back toward the source.
• Sound Refraction. This little known effect occurs when noise is dissipated, diffused or dispersed by striking a rough surface on any plain.
• White Noise. It is designed to create sound that is appealing to the human brain as a mask for undesirable noise. The most widely used method is a fountain that makes loud splashes.

Using these bee-pollinated plants between estates in the public ambling area and between the houses/gardens and the noise will reduce that relevant noise level using the Sound Absorption Method; and be suitable for everyone including Hay Fever sufferers:-

• 1. Install chain link fence on strong supports with 12 inch (30 cms) gap at bottom (to allow local wildlife - hedgehogs, foxes, badgers, frogs and newts access) and 48 inch (120 cms) chainlink between 12 and 60 inch (30 and 150 cms) from ground on estate boundary. Add 4th Line Wire on top links to prevent that chainlink from sagging. Plant ivy, Rosa with it's 'Single Flowers' cultivars (see below) and thornless blackberries so that they can then climb onto that chainlink fencing within the inside of that public ambling area.
• 2. Plant mixture of bulbs, evergreen perennials, herbaceous perennials, deciduous shrubs, evergreen shrubs, which grow between 18 and 96 inches (45 and 240 cms) high - add the eventual width of a pair and divide that by 2 as the planting distance between them. This combined with their different heights will produce a random effect in this minimum-width of 96 inches (240 cms) area and 72 inch width (180 cms) of area 4. It is also most likely that viewing from one side to the estate boundary, you are unlikely to see the bottom of the chainlink. Use 30% evergreen and the rest is herbaceous/deciduous to provide a change throughout the year for the estate inhabitants to enjoy on their rambles. The blackberries on the estate boundary and the fruit from each of the 3 cherries, 3 apple and 3 pear for each estate can either be enjoyed by the humans or the wildlife. Mulch the area with 4 inch thick (10 cms) of Bark before planting and thoroughly soak the ground after planting. Then, sow White Clover (see Green Manure) over the whole of both areas 2 and 4 to provide Nitrogen to the other plants and reduce evaporation of the irrigated water in between the 2 soakings each year.
  Thoroughly soak the ground in August to provide the shrubs and fruit trees with the water to be stored in their roots and then be used during the spring foliage production. Thoroughly soak the ground again in April to provide their water supply during the later spring and summer.
• 3. 48 inch wide (120 cms) path using Cedargravel. After the Cedargravel is installed, use different coloured pea-shingle to create games like snakes and ladders, hopscotch or noughts and crosses or a picture. This path allows the rain to drain through and be used by the plants on either side. If you wear women's high heels, you will have no problem walking on this path. You can also use it for remote-controlled model cars or landing remote-control model aircraft.
• 4. A repeat of of 2. without the blackberries or fruit trees - If the fruit is only on the other side of the path, then the fruit pickers will not be tempted to try the home owners side.
• 5. Install chain link fence on strong supports with 72 inch (180 cms) chainlink on top of ground level on private garden boundary. Add 4th Line Wire on top links to prevent that chainlink from sagging. Plant ivy so that it can then climb onto that chainlink fencing from inside the public ambling area.

If the house owner has a noise problem from outside their property, then they can use the same solution as above using 1, 2, 3 and 4 only. Their sheds and storage facilities can be installed in area 4 with path 3. leading to them.

Single flowered cultivars (some are marked as 'Single Flowers') are more useful to bees than double flowered cultivars.
Bloom type depends on the number of petals for Roses:-

• Single blooms are fully opened and almost flat, consisting of 1-7 petals per bloom.
• Semi-double blooms consist of 8-15 petals in two rows.
• Double blooms consist of 16-25 overlapping petals in three or more rows.
• Full: 26-40 petals in three or more rows.
• Very full: 40+ petals in three or more rows.

The list is sorted in the following table under the height of plant range:-

Below 2 feet - 24 inches (60 cms) - in height
Between 2 and 6 feet - 24 and 72 inches (60 and 180 cms) - in height
Above 6 feet - 72 inches (180 cms) - in height

 

The final column shows the value of the plant to bees (honeybees and hive bees):

• N and P indicate that they collect Nectar and Pollen, respectively.
• Plants especially used by Bumble Bees are marked B.
• The absence of all 3 entries (N,P,B) for a few plants reflects insufficiency of observations as to what it is that bees collect from that plant.

1000mm = 100 cms = 1 metre = 40 inches

The bee can pollinate the flower, which can then produce a seed. Hymn 881 then instructs the seed:-

Push, little seed,
push, push, little seed,
till your head pops out of the ground.
This is the air,
and now you are there
you can have a look round.
You'll see God's sky,
you'll see God's sun,
you'll feel his raindrops one by one,
as you grow, grow, grow, grow,
grow to be wheat for bread.
So push, little seed,
push, push, little seed,
that the world may be fed.

For my recommendation on what to do with your prunings, kitchen scraps and grass mowings see Compost Bins in Companion Planting Page C, instead of composting them in a small 1 cubic yard domestic garden compost bin.

Top ten plants that are bad for bees from Countryfile Magazine

"Lavender, alliums, fuschias, sweet peas - keen gardeners know the very best flowers to entice bees to their gardens. But what about plants that are  bad for bees? Here is our expert guide to the top ten plants that you should avoid to keep bees happy and buzzing, plus the perfect alternatives.

1. Rhododendron
Spectacular and beautiful, not many people know the common rhododendron hides a poisonous secret – its nectar is toxic to bees. It’s common practice for beekeepers to keep their hives closed until the flowering season is over. The resulting honey from rhododendrons has also been known to contaminate honey, making it unsafe for humans to eat.
Alternative: Clematis have beautiful, wide flowers and are 100 per cent bee-friendly.

2. Azalea
Rhododendron’s sister, azaleas are also toxic to bees.
Alternative: Foxgloves (Digitalis) are a bee favourite and despite being poisonous if consumed by humans, they are both honey and bee safe.

3. Trumpet flower, or angel’s trumpet (Brugmansia suaveolens)
Though ornamental and sweet smelling, the trumpet flower’s nectar can cause brood death in bees and is best avoided.
Alternative: Try honeysuckle (Lonicera) instead for deliciously scented results.

4. Oleander (Nerium oleander)
Harmful to butterflies as well as bees, oleander has a severe effect on hives. Nectar taken to the hive concentrates as it dries out, which increases the amount of toxins and usually results in a mass hive wipeout. 
Alternative: Snapdragons (Antirrhinum majus) are equally as bright and arguably more attractive in small or large gardens.

5. Yellow Jessamine (Gelsemium sempervirens)
Pleasantly aromatic and attractive as they are, bees are often poisoned by the vines and flowers of the yellow jessamine and its toxins are said to be as severe as hemlock.
Alternative: Plant Black-eyed Susans (Rudbeckia hirta) in tubs and along fences for a pretty, easy-to-grow substitute.

6. Mountain Laurel (Kalmia latifolia)
Part of the blueberry family, the mountain laurel is an evergreen shrub with sweet, white or pink flowers when in bloom. Pretty they may be, but the honey produced by mountain laurel is toxic to humans and is often bitter tasting.
Alternative: Lilacs (Syringa) are both beautiful and wonderfully sweet smelling. Easy to grow and are loved by bees and butterflies. 

7. Stargazer lily (Lilium 'Stargazer')
Stunning but deadly to cats, stargazer lilies’ pollen is poisonous to bees.
Alternative: Hollyhocks (Alcea) are impressive and just as beautiful as the stargazer but bee-friendly.

8. Heliconia Exotic and interesting, heliconia, or lobster-claws as its sometimes called, is very toxic to bees. You should not prune your heliconias, as the 'stem' is actually made up of rolled leaf bases and the flowers emerge from the top of these 'pseudostems'. However, each stem will only flower once, so after flowering you can cut that stem out. This is recommended, to encourage more flowering, to increase airflow in between the stems of your plant, and also to generally tidy it up and improve the appearance.
Alternative: Although not quite as exotic, hyacinths are fragrant, gorgeous and easy to grow. Hyacinth bulbs are poisonous; they contain oxalic acid. Handling hyacinth bulbs can cause mild skin irritation. Protective gloves are recommended.

9. Bog rosemary (Andromeda polifolia -
All parts of the plant contain andromedotoxin and are considered poisonous)
Not to be confused with the herb, bog rosemary is acutely poisonous and the honey produced from the nectar of Andromeda polifolia contains high enough levels of grayanotoxin to cause full body paralysis and potentially fatal breathing difficulties due to diaphragm paralysis.
Alternative: Why not try planting a classic rosemary bush (Rosmarinus officinalis) – aromatic, resilient and favoured by bees.

10. Amaryllis (Hippeastrum)
Now most commonly recognised as decorative Christmas flowers, amaryllis are gorgeous in bloom but their pollen produces toxic honey. Bulbs, chewing or ingestion of the bulbs, leaves or flowers poisons goats and sheep with Lycorine (An emetic) and small amounts of alkaloids.
Alternative: Dahlias are a highlight of late summer gardens. Beautiful and simple to grow, dahlias often flower until the first frosts of the year."

The following details come from Cactus Art:-

"A flower is the the complex sexual reproductive structure of Angiosperms, typically consisting of an axis bearing perianth parts, androecium (male) and gynoecium (female).    

Bisexual flower show four distinctive parts arranged in rings inside each other which are technically modified leaves: Sepal, petal, stamen & pistil. This flower is referred to as complete (with all four parts) and perfect (with "male" stamens and "female" pistil). The ovary ripens into a fruit and the ovules inside develop into seeds.

Incomplete flowers are lacking one or more of the four main parts. Imperfect (unisexual) flowers contain a pistil or stamens, but not both. The colourful parts of a flower and its scent attract pollinators and guide them to the nectary, usually at the base of the flower tube.

Androecium (male Parts or stamens)
It is made up of the filament and anther, it is the pollen producing part of the plant.
Anther This is the part of the stamen that produces and contains pollen. 
Filament This is the fine hair-like stalk that the anther sits on top of.
Pollen This is the dust-like male reproductive cell of flowering plants.

Gynoecium (female Parts or carpels or pistil)
 It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.
Stigma
This is the part of the pistil  which receives the pollen grains and on which they germinate. 
Style
This is the long stalk that the stigma sits on top of ovary. 
Ovary
The part of the plant that contains the ovules. 
Ovule
The part of the ovary that becomes the seeds. 

Petal 
The colorful, often bright part of the flower (corolla). 
Sepal 
The parts that look like little green leaves that cover the outside of a flower bud (calix). 
(Undifferentiated "Perianth segment" that are not clearly differentiated into sepals and petals, take the names of tepals.)"

The following details come from Nectary Genomics:-

"NECTAR. Many flowering plants attract potential pollinators by offering a reward of floral nectar. The primary solutes found in most nectars are varying ratios of sucrose, glucose and fructose, which can range from as little a 8% (w/w) in some species to as high as 80% in others. This abundance of simple sugars has resulted in the general perception that nectar consists of little more than sugar-water; however, numerous studies indicate that it is actually a complex mixture of components. Additional compounds found in a variety of nectars include other sugars, all 20 standard amino acids, phenolics, alkaloids, flavonoids, terpenes, vitamins, organic acids, oils, free fatty acids, metal ions and proteins.

NECTARIES. An organ known as the floral nectary is responsible for producing the complex mixture of compounds found in nectar. Nectaries can occur in different areas of flowers, and often take on diverse forms in different species, even to the point of being used for taxonomic purposes. Nectaries undergo remarkable morphological and metabolic changes during the course of floral development. For example, it is known that pre-secretory nectaries in a number of species accumulate large amounts of starch, which is followed by a rapid degradation of amyloplast granules just prior to anthesis and nectar secretion. These sugars presumably serve as a source of nectar carbohydrate.

WHY STUDY NECTAR? Nearly one-third of all worldwide crops are dependent on animals to achieve efficient pollination. In addition, U.S. pollinator-dependent crops have been estimated to have an annual value of up to $15 billion. Many crop species are largely self-incompatible (not self-fertile) and rely almost entirely on animal pollinators to achieve full fecundity; poor pollinator visitation has been reported to reduce yields of certain species by up to 50%."

The following details about DOUBLE FLOWERS comes from Wikipedia:-

"Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. The double-flowered trait is often noted alongside the scientific name with the abbreviation fl. pl. (flore pleno, a Latin ablative form meaning "with full flower"). The first abnormality to be documented in flowers, double flowers are popular varieties of many commercial flower types, including roses, camellias and carnations. In some double-flowered varieties all of the reproductive organs are converted to petals — as a result, they are sexually sterile and must be propagated through cuttings. Many double-flowered plants have little wildlife value as access to the nectaries is typically blocked by the mutation.

There is further photographic, diagramatic and text about Double Flowers from an education department - dept.ca.uky.edu - in the University of Kentucky in America.

"Meet the plant hunter obsessed with double-flowering blooms" - an article from The Telegraph.
