Forsythia × intermedia ‘Lynwood’ (tentative)

Douglas and I have tentatively identified this as the cultivar ‘Lynwood’, though it could be another.

Thank you to fotrristi@Flickr for sharing today’s photograph via the Botany Photo of the Day Flickr Pool (original).

Thanks to their aggressive, sprawling nature, the forsythia you will most often encounter is this hybrid of Forsythia viridissima (an upright, green-stemmed species) and Forsythia suspensa (an arching, weeping species).

Each spring at my old, colonial home in New Hampshire, my father and I would go out almost every week to snip branches off our forsythia bushes to garnish our dining room table with. The fresh floral smell with the sprightly, yellow colour truly brought the long awaited spring season into the home.

These often spindly bushes are ridiculously easy to grow. Our neighbour pulled up one that became too big for his backyard. We dragged a chunk of it home, stuck it in a shallow hole and watered it. It had no problem adjusting to its new home.

A full sun location will get the best results, but forsythia are not picky. With too much shade they can become bare and woody. It is a good idea to cut them back each season to keep them dense, but please refrain from shaping them into balls or lollipops.

Forsythia bushes will grow to be a maximum of 6 feet and sprawl to be almost twice their height if not maintained. The flowers are four-lobed or 4-merous which is convenient for the memory. The four petals of the corolla are adnate at the base, fusing to form a tube. Often the buds can be sensitive to the harsh northern and prairie winters, although the branches will survive through temperatures exceeding -38 ºC. So if you live in an extreme environment, and your Forsythia doesn’t flower this year, just hang on and maybe next year it will snap out of it.

    Wow, gorgeous photo with those strong contrasting colors!

    Nice photo and description. We had an unusual week of -30F temps here in Ohio about a month and a half ago. Our Forsythia only bloomed at the base of the plant or if it was closer to the house (heat source). Maybe we’ll see nice blooms next year!

    I collect some plants but still love my Forsythia and can’t imagine a spring without those blooms at the end of winter.
    Just pruned ours last week after a glorious, huge display – they will indeed get huge if not maintained.

    We tried to grow Lynwood in the Adirondacks. It still needs protection. Pretty arid winters here.

    What a beautiful photo. It even shows the glossy texture of the corolla. But I seem to count 5 petals?

    Thank you for showcasing another wonderful and unique plant; there’s no place like Botany Photo of the Day. I love to see the many horticultural varieties of a particular species so much, and I always look to this site for new botanical experiences. I was so happy to see this one — never mind that I have seen it at this time of the year for many decades and still get a thrill. Bring on the tulips! (Gasp! Have they passed already? The deer got nearly all of mine.) Does Burpee have any new marigolds this year?

    There is a Forsythia X intermedia ‘Goldleaf’ that is absolutely outstanding. The color of the foliage is almost the same as the flowers. So the gold color continues through most of the summer. We have a specimen of this cultivar at our Demonstration Teaching Gardens and we are always having people ask where they can find one.

    On size, Forsythias can easily reach 3m tall, sometimes more.
    Does anyone know if this hybrid is sterile? I’ve never seen a Forsythia produce fruit, and wonder if this is genetic or due to the local climate here.

    Sometimes they will bloom sparsely late in the fall, for some reason, and then usually I don’t see flowers in the spring. : (

    Yep-5 petals on this one! Probably why the picture was taken! In Ohio-forsythia is one of the plants used in our phenology gardens-gardens scattered about Ohio used for predicting pest emergence! Link to bulletin: http://ohioline.osu.edu/sc195/016.html

    I recently moved from southern California and this is my first Spring in Maryland. These delightful bushes are everywhere-huge WOW! factor for me! and such a welcomed sight after winter.

    This great image shows a 5-petal flower. As I was growing up, most forsythias seemed to be 4-petaled, and I remember thinking it was remarkable when I found a branch with flowers of 5 petals. Does anyone know about forsythia petal number, and how it might relate to our molecular understanding for flower development?

    We are still waiting for the forsythia to blossom – cold and snow, and rain, and more cold, plus nasty winds, all have kept the blossoms away here in Mississauga. Lovely photo indeed.

    my mother would bring in branches
    to force into bloom for easter
    pussey willows and little dishes
    of pebbles and paper white bulbs
    i fully enjoy the flower riots of spring

    We have forsythia cuttings blooming in our living room every spring, but with only 4 pedals. No need to wait for the slow Ontario spring.
    The Cabbagetown Forsythia Festival, which happens on the first Sunday of May, has been celebrated for about 30 years. This has encouraged a lot of Forsythia planting and our neighbourhood will look wonderfully yellow soon. It is always interesting to see if the blooms will cooperate with the planned date of the festival. It is different every year.

    We used to have a house with a semi-hardy forsythia. Some years it would bloom only on the bottom several inches, where the branches had been consistently covered with snow.

    My son and I just found a forsythia flower with five petals on a branch we brought in to force. All the rest have four petals. It was almost as exciting as finding a four-leaf clover! Nature found its own way to interest my kids in gardening.
