Lime trees can provide honeydew, a sugary excretion produced by aphids, that, like nectar, is made into honey. Their nectar can be variable and is said to be better when the weather is hot and humid.
The nectar makes a green, minty honey. The pollen is difficult for bees to collect.
Includes Tilia cordata, T.x europea (Common lime), T.maximowicziana, T.petiolaris, T.platyphyllos, T.tomentosa.
Tilia x euclora , T. x orbicularis, T. petiolaris, T. tomentosa – no honeydew
Dead bees can sometimes be seen beneath lime trees. The victims are a species of bumble bee (Bombus lucorum) and the limes are non-native varieties ie Tilia petiolaris, T. orbicularis. Native limes (T. cordata and T. platyphyllos) are safe for all bees. Varies from year to year and Hooper suggests all limes may have some degree of toxicity. Can stupefy honey bees but can be toxic to bumble bees.
