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.
Rhododendron’s sister, azaleas are also toxic to bees.
Alternative: Foxgloves 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
Though ornamental and sweet smelling, the trumpet flower’s nectar can cause brood death in bees and is best avoided.
Alternative: Try honeysuckle instead for deliciously scented results.
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 are equally as bright and arguably more attractive in small or large gardens.
5. Yellow Jessamine
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 in tubs and along fences for a pretty, easy-to-grow substitute.
6. Mountain Laurel
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 are both beautiful and wonderfully sweet smelling. Easy to grow and are loved by bees and butterflies.
7. Stargazer lily
Stunning but deadly, stargazer lilies’ pollen is poisonous to bees.
Alternative: Hollyhocks are impressive and just as beautiful as the stargazer but bee-friendly.
Exotic and interesting, heliconia, or lobster-claws as its sometimes called, is very toxic to bees.
Alternative: Although not quite as exotic, hyacinths are fragrant, gorgeous and easy to grow.
9. Bog rosemary
Not to be confused with the herb, bog rosemary is acutely poisonous and the honey made from this plant can cause paralysis to humans.
Alternative: Why not try planting a classic rosemary bush – aromatic, resilient and favoured by bees.
Now most commonly recognised as decorative Christmas flowers, amaryllis are gorgeous in bloom but their pollen produces toxic honey.
Alternative: Dahlias are a highlight of late summer gardens. Beautiful and simple to grow, dahlias often flower until the first frosts of the year.
