Leaves also have extra-floral nectaries but I have to yet find honey bees foraging on them. June 10th, I saw a tall catalpa tree has flowers already. This year we have harvested about 700 lbs of honey so far and they tasted like basswood (extracted July 7th-ish). June 16, basswood ( Tillia americana, Tilliaceae) is blooming! I noticed that different trees will bloom at very different times. Poison ivy was also blooming and I waited for 5-10 min each time I go there and saw honey bees, which is good news! I certainly do not want to come into contact with its pollen! It seems to provide both nectar and pollen. I think the flowers I saw were all females, the species is diecious (male and female flowers on different trees). June 18, Staghorn sumac ( Rhus typhina, Anacardiaceae) started blooming and many honey bees foraging on them.

This is the host plant for the iconic monarch bufferflies but honey bees will forage on them also. June 22, common milkweed (Asclepias syriaca, Asclepiadaceae) starts to bloom. July 3, I finally got some nice photos of honey bees foraging on the leaves of catalpa! There are 6 trees in the MSU Horticulture Demonstration Garden. Silver leafed bassword ( Tillia tomentosa, Tilliaceae) are blooming on the same day. There are 4-5 in front of Natural Science, but my photos were taken near Bogue and Shaw intersection. July 5, the golden rain tree ( Koelreuteria paniculata, Sapindaceae) is blooming at MSU campus. Being an excellent honey plant, both honey bees and bumble bees are feasting on the beautiful flowers.
#Bloom and bee Patch
There is a large patch near Cornell and Hatch in Okemos (it likes swamp or wetlands). July 9, buttonbush ( Cephalanthus occidentalis, Rubiaceae) just started blooming. A list of common honey plants in Michigan are here. This is this year’s (2016) flower report, updated at 1-2 week intervals. Flowers photographed in ultraviolet, visible light and simulated insect vision. (2015) Helianthus tuberosus L.(Asteraceae) Jerusalem Artichoke. Flowers photographed in ultraviolet and visible light. ex Sims (Plantaginaceae) Foxglove Beardtongue. (2014) Lonicera japonicaThunb (Caprifoliaceae) Japanese Honeysuckle. (2014) Hoya carnosa Thunb (Apocynaceae) Wax Plant. (2014) Disocactus ackermannii (Haw.) Barthlott (Cactaceae) Orchid Cactus. Flowers under ultraviolet light as a “formal publication” for references on : Misty flower (Eupatorium coelestinum), and a tagged bee foraging!.Kentucky yellow wood and Kentucky coffee tree.Spring flower 1: Winter-aconite, Eranthis.I will slowly populate this page with bee plants (nectar or pollen) as time goes by. Here are links to my posts about various flowers (approximately by their flowing time).
