I won’t go on with all the others here. You can read the book if you’d like more information.
Armed with all this information, I went back to the Hydrangeas for American Gardens book to see what he said about all
these varieties. Hydrangeas for American Gardens is a newer book just published in 2004. In the section on “Hydrangea
macrophylla”, I read where extensive breeding of some cultivars listed as very hardy in the other book was developing
good mildew resistance and other desirable traits. Bailey Nurseries, Inc., St. Paul, Minnesota, discovered a plant with
special remontant (reblooming in the same season) and began developing it further. A plant patent was obtained for this
plant, ‘Endless summer’ (‘Bailmer’) to protect the rights to it. Many were released in 2003, more in 2004. Now I see it
listed in Fritz Creek’s Catalog and Margaret at Alaska Mill and Feed says they will have it this spring for sale. So now we
are all in on the latest information. Isn’t that fun? Of course, this isn’t the end of the story because now ‘Endless
Summer’ is being propagated and crossed, with the “rest of the story” to come in the following years.
This is what is written about ‘Endless Summer’: Mophead flower type, pink to blue color, medium green foliage, 3’ to 4’
tall, Blooms in June. ’Endless Summer’ is remontant, which means it could get an early frost that kills the buds (or a moose
could nibble them) and then still bloom about 10-12 weeks later from new shoots. For continuous color, one could remove
half the flowers, allowing the remainder to dry on the plant while the new shoots are producing flower buds for the later
show, in October, if weather allows. Fritz Creek catalog calls it a zone 4, and 5’ tall. Moist, well-drained soil, mostly sun
is recommended. It is for sale for $28 in a 1.5 gallon pot.
Others for sale in the Fritz Creek Catalog are:
aborescens - rated ****, large cluster of flat, white flowers and large green leaves.
‘Limelight’ paniculata – Cone-shaped flower, bright green in spring and pink, burgundy and green in fall , 7’ tall, Zone 2, 2
gal pot - $22.
‘Little Lamb’ paniculata - unique, compact form, small, full panicles of tight white florets. 7’tall, Zone 2 gal. Pot for
‘Peegee’ paniculata grandiflora – rated ***, 6’ tall, Zone 3-4, 1 gal. Pot $10.00
upright habit, white flowers turning reddish pink in summer,
7’tall, Zone 2, 2 gal. Pot $22.00
Alaska Mill and Feed will have ‘Endless Summer’, ‘Diamond
Pink’ and ‘Peegee’ for sale. I don’t know the size and price
at this time. This is not a book report or a plug for these
nurseries. I hope the information is of interest to you.
There certainly was more information in the books
mentioned than I could digest. Now, at least, I know
enough to be able to purchase hydrangea with confidence.
Notice, I didn’t say I will purchase one. I’m still thinking
about it. If you have any feedback or further information,
I would appreciate feedback.
This year I have two endless summer's out I think they were $18 from bells as mentioned in another post I also grow Kiwi outside hydrangea grown in a large container can also be brought in cut back and made into a house plant for the winter.
