But I had never thought of planting hostas en masse, purely for their flowers. There are more than 58 varieties of hostas that have evolved from Hosta plantaginea. They all bloom in August and are prized for their lovely pure white flowers and strong, sweet fragrance. They need ample sun to bloom, and the flowers open in the late afternoon instead of early morning like most hostas.
Some of the most well-know culitvars of H. Since hostas are members of the Liliacea family, they produce funnel-shaped blooms on scapes that arise from the center of the plant. Like day lilies, individual flowers last for only one day. The plant may produce ten or more scapes with up to 50 flowers per stem, so the bloom time can last of weeks. By planting different cultivars, you can have hosta flowers in your shade garden from May until frost.
Most of us are unimpressed with the lanky scapes and violet blooms of common green hostas. But hosta flowers can range in color from deep purple to white infused with pink. Others feature unusual flower scape forms, almost resembling scepters, like those of the 'Blue Dolphin' hosta. One of the latest hybridizing trends has been to create branched flowers, as seen in this example created by Tony Avent of Plant Delights nursery. The biological control Nemaslug is also a good option, as are copper bands, which can be placed around pots.
You can also try setting beer traps or mulch the area with sharp gravel. It has small, delicately pointed leaves in a vibrant shade of lime green, and each leaf has an attractive darker green edge. The flowers are dark mauve. The broad, pointed leaves appear thick and cushioned, and are an intense, smoky blue, with striking white margins. Lilac flowers appear in summer.
This variety produces a dense cluster of small leaves, each with a contrasting lime green, irregular margin. The flowers are purple. The leaves are elongated and delicate, with thick white margins at the beginning of the season, then changing to a yellowish-green later in the summer. Also grows well in a sunny position. Ideal for creating a contrast among broad-leaved hostas, it bears lavender-coloured flowers. Each leaf is an attractive smoky-blue colour — almost round — while the flowers are lilac.
It produces a bright contrast in shady areas, as the deep-green leaves are variegated with a cream-coloured central flare. The lilac-mauve flowers appear in summer. It has very dramatic, large heart-shaped foliage in a fresh, spring-green colour, brightened with irregular white margins.
This is also a slug-resistant hosta variety. This medium-sized variety reaches a height and spread of around. It then bears white flowers from June to July. This huge hosta bears very large slightly cupped leaves in chartreuse to gold.
Lavender flowers appear in July. Browse the fantastic range of fully mature hardy perennials, shrubs, ferns, grasses and bulbs to create a spectacular garden to enjoy all year round.

None of my large blue or yellow leaved hostas are coming up yet as they shouldn't but did see today that Empress Wu, Sagae, Stained Glass and a few others are. I have about 85 varieties in pots here just south of San Francisco. All but about 4 or 5 are up and unfurling. Spring is here. Franknjim is correct about them coming up in about the same order each year. The first ones are always first, and the last ones are always last. The Tokudamas are the slowest here. I am a bit north and east of Franknjim and about half of my hosta are up but only Lancifolia unfurled yet.
I think soil moisture as well as sunlight affect when a given variety of hosta emerges from dormancy. I live in the 6a zone. I only have 17 different types of hosta, but the only ones showing so far are a couple of Sieboldiana Splendis with a couple of Sieboldiana Francee showing some root activity. I have Blue Angel and 14 others that have not shown any signs of life.
It is forecast to be 81 degrees here today, so maybe there will be some activity tomorrow morning. As Dorothy said to Toto we're not in Kansas anymore. I did look closer and one of my Blue Angels does have one eye poking through the ground.
The others aren't up yet, and I have not dug and will not dig to see if they are still alive. Thanks for all of the information. I will stop worrying now. Here in Southern Ontario my hostas always show up well after most of my other perennials, and after the spring bulbs are up and blooming.
My gardens are quite green now, daffodils blooming, tulips ready to open, but hostas just starting to peek. Hostas are late to emerge -- and so a challenge to remember where they are and not step on them while picking a bouquet! They will eventually appear! After yesterday hitting 84 degrees the forecast for SE Massachusetts is 29 degrees for Saturday and Sunday night. It looks as if the hostas were not fooled as they are not close to opening up and, in most cases, even making a showing here.
My hostas are on the North side of my house and receive mostly shade. The ground over there, although not frozen, is considerably cooler than the ground in other parts of my yard. This is the first spring that I have had them in the ground, so it will give me a good idea of when I can expect them to break dormancy in the following years. Of three hosta in the ground from last year, only H.
The H. I saw a lot of tunnels dug around it, beneath the winter leaf mulch, which might explain its absence. All of my containerized hosta are showing life, except for H. All the others I moved with it from zone 5b to 9a are doing fine, that I can tell. Somewhere along the line I lost H. I do not like to gamble on my plants, and it seems that putting them in the ground here is risking their well being more than keeping in containers.
Okay, 3 out of 4 of my blue angel hostas are now poking their eyes up through the soil. One hasn't emerged yet, so hopefully its just a late bloomer. I have more hostas coming around May 1st. If the fourth blue angel isn't up by that time, then I will dig down a little bit to see if it survived. If not I will replace it with an earth angel hosta I have coming in May. Thanks for al of the information. I appreciate it.
Life is good, saw eyes of Komodo Dragon above the mulch, and several eyes each of Jurassic Park and Satisfaction under the mulch! They are highly appreciated here. Bernd, would you please remember to post a picture of your Satisfaction when it gets up good?
Mine now has a light lavenderish blossom on a single scape, and it is, to me, a beauty, plant, flower, all. Moccasin, I will try to remember. I like when a plant added some eyes, went from 1 last year to 4 now. Satisfaction was created by Bridgewood Gardens, I bought a little plant in fall of from them in a sale, should look much better in 2 months when leafed out. Now, Jurassic Park should get really big some year, had 1 eye last year, now 4. This year it should be the year when hostas planted in and really take off in my garden, can't wait!
My fourth Blue Angel hosta started to emerge yesterday! I thought it would though. On Wednesday I could feel a bump in the soil like something was beginning to push its way up and then yesterday the hosta eye was peeking through the surface of the ground. Plantingman,check out my post about really ahead,and you'll see how hostas already look down here in NC! The one I think might be the OLD Brother Stefan has two eyes growing taller daily, and the new Brother Stefan, my backup, has three really pretty leaves opening as well.
Very judiciously, I moved the slow plants into more sun, and then moved the Patriot out of the sun Its been growing for about a month now, and I just learned it needs to be sheltered from the sun more. Every day, I go to my courtyard corner of the garden, and sit for about an hour watching hosta grow.
Today, I was also potting peace lilies, bird of paradise, strawberries, as well as my orders received. I think one of the hosta grew in the shipping container, Fried Bananas, because the tall leaf was scrunched down at the end. As a general rule Hosta emerge 30 to 45 days after the snow clears the ground above it If you've reached your mid-season for your gardening zone and you've not seen your hosta where it ought to be then there is a fair chance that the plant either:. Froze out.
This means you will find remains of rhizomes under the ground with no living tissue Experienced Crown Rot. This means you will find absolutely NO evidence of the plant below the ground as the plant rotted to nothing. But that does not mean that the topic is any less important. For those who are still exploring hosta today the topic can still be a good read. Good knowledge never fades it just still needs to be there for others to find.
Just thought I'd add to the knowledge base. I'm in Portland, OR zone 8 and after a wet winter my hostas started to emerge in the last weeks of March.
They were planted in mid-September of the previous fall. They sit on the north side of my house in shade, so the soil is cooler than the rest of my yard.
Soil temperature maps are showing that Portland soils are still in the mid degree range, but I haven't measured my soil directly. The previous poster has it closest. That's when the hosta will spike.. This year I will be adding about 20 of the mouse ear hosta; Two white feather, and a few Itsy Bitsy Spiders! I am in Eastern Ontario, my hostas are in a raised bed under trees with a lot of shade.
