Six on Saturday: Firsts

The first and last may potentially suggest that this is an episode of the Red Green Show.

1. Hedychium greenii, red butterfly ginger, which I accidentally took from Brent Green’s garden with a bunch of crowded out Heliconia psittacorum, is now about to bloom here. I was totally unaware that it was here until Brent mentioned that it was no longer there.

2. Hedychium gardnerianum, kahili ginger bloomed during the pandemic, while no one was here to see it. Then, gophers ate it. I canned the remnants, which are blooming now. This is the first of several florets to bloom on the first tall floral spike. It smells like 1986.

3. Agapanthus orientalis, lily of the Nile suddenly bloomed with this single white umbel within an exclusively blue colony. I removed the offending shoot as bloom began to fade, but found that it is not completely white. I canned it to observe how it blooms next year.

4. Begonia boliviensis ‘Santa Cruz’ begonia was not my idea. Another horticulturist here just procured it from a nursery in Santa Cruz, a few miles away. It is quite happy here in Santa Cruz County. It deserves a more appealing name, such as ‘Los Gatos’ or ‘San Jose’.

5. Canna ‘Cannova Mango’ canna was not my idea either. Brent sent it to me. I am not at all keen on modern cultivars, particularly this color. I nonetheless divided it too much to bloom well. This is its first opportunity to demonstrate how profuse its bloom should be.

6. Canna that was a gift from friends of a friend last winter is now blooming here. I have no idea what cultivar it is, and I do not care. Gifts are always better than nursery surplus from Brent’s projects. It is elegantly tall with simple red bloom and simple green foliage.

Pollinators Are As Busy As Bees

Flower breeding is not for pollinators.

Flowers bloom for pollination. It is that simple. Most rely on wind to disperse their pollen. They are more abundant than colorful or fragrant. More prominently colorful and fragrant flowers rely on pollinators. Their color and fragrance attract preferred pollinators, such as insects, birds or bats. Such flowers sustain their pollinators with nectar or surplus pollen.

More than pollinators appreciate their diligence. Almost everyone who enjoys gardening enjoys floral color and fragrance. Cultivation of naturally appealing bloom began several thousand years ago. Selection and breeding most likely began relatively soon afterward. Ultimately, during relatively modern history, hybridization began getting too complicated.

Pollinators were not a priority during such processes. Because most ornamental flowers produce no usable fruit, pollinators are unimportant. Because of extensive hybridization, many ornamental flowers are sterile anyway. Floral color, fragrance and various tangible attributes are more important. Modern bloom appeals more to people than to pollinators.

A few modern flowers now confound their original pollinators. Some types of insects can die of exhaustion while trying to ascertain them. These insects may recognize floral color or fragrance but not strange floral structure. A few modern flowers are too frilly for access. Some attract pollinators without providing enough nectar or extra pollen to sustain them.

Several exotic flowers with less or no breeding distract pollinators with their abundance. Lemon bottlebrush blooms very abundantly and is still common within some landscapes. Blue gum eucalyptus is naturalized in parts of California. Both attract monarch butterflies that native species rely on. Native ceanothus must instead rely more on other pollinators.

Furthermore, a few pollinators actually disrupt native ecosystems. Honey bees, although very important to local agriculture, are not native. They arrived in San Jose in 1853, from where they dispersed throughout the West. It is now impossible to assess their influence. Even seemingly beneficial influence is unnatural and therefore ecologically detrimental.

Six on Saturday: P III

P was about a white blooming perennial pea, Lathyrus latifolius, that I recently found to replace what I inadvertently lost earlier. P II was irrelevant to both that and this, but did happen to get a title that incorrectly designates it as a sequel to P, and prevents me from using that title for this Six on Saturday post with three variants of perennial pea and the more typical sort. Perhaps I should not have expended such effort for such a weed. What is worse is that I canned and am now growing copies of the three variants as well as the favored white blooming variant.

1. Canna are irrelevant to the primary topic, but are too cool to not mention. These were placed here temporarily in random pots until a new landscape gets installed next winter.

2. Canna musifolia dominates, which is why there is not much bloom. This one stands a bit more than eight feet high in its pot. It might be ‘Omega’ like the compact Oldsmobile.

3. Lathyrus latifolius, perennial pea is the primary topic because I found three variants. This one blooms with swirled pink flowers. It is about as rare as those that bloom white.

4. This looks white in this picture but is actually blushed very slightly with pink. I should have gotten a better picture. I dug and canned a copy because I had never seen it before.

5. This is the typical floral color of the species. To me, it looks purplish pink. I am not so proficient with color. Others say it is pinkish purple. It justifies my preference for white.

6. Like the picture of the very slightly blushed white flowers, this is not a good picture of flowers that seem to be slightly richer purple than the typical purplish pink. I got a copy.

Hollyhock

Hollyhock was more popular within Victorian gardens.

Old fashioned hollyhock, Alcea rosea, can be a bit too imposing for small gardens, since their spire like flower stalks can get taller than eight feet. Modern varieties are more proportionate, standing about five or six feet tall. Some are only about two and a half feet tall. Many modern varieties also have fluffier semi-double or double flowers. Those with smaller flowers have denser flower set than old varieties (Flowers are closer together on the stem.).

The three to five inch wide flowers bloom through summer in shades of pink, red, purple, pale yellow, pale orange and white. Removal of spent flower stalks may promote shorter autumn blooms, but also prevents self sowing. Seed can be sown at the end of summer for blooms next year. The coarsely textured and variably lobed basal foliage does not get much wider than two feet. Snails and rust can be problematic.

What Is This IV?!

Rotheca myricoides / Clerodendrum myricoides ?

It is not a species of ivy. ‘IV’ is merely its Roman numeric designation as the fourth species that I am unable to identify since I started assigning numeric designations to them. So then, what is it? I suspect that it is likely Rotheca myricoides, which is alternatively known as Clerodendrum myricoides. ‘Ugandense’ is a cultivar name that, in typical modern tradition of botanic nomenclature that violates the simple standards of botanic nomenclature, now seems to be an acceptable species name in conjunction with either genus name. Its common names include butterfly flower, blue butterfly plant and blue butterfly bush, although the latter sounds more like a cultivar of Buddleia. I have not actually confirmed its identity, and I have no idea how it got into one of our landscapes. It grew under the carcass of a Brunfelsia pauciflora, yesterday, today and tomorrow, which did not survive my meager attempt to salvage it from compost. I can only assume that it arrived, most likely as an ungerminated seed, with the now deceased yesterday, today and tomorrow. It initially grew quickly with only two straight canes about four feet tall. I would have pulled it as a weed, but was intrigued by it. It did not grow much this year, but instead took time to branch, and is now taking time to bloom with these few intricate flowers on top. I am now pleased that I did not pull it as a weed. If it really is butterfly flower, it can get a bit taller than it already is. So, because it grew in front of an exemplary sasanqua camellia, I will likely relocate it to a more appropriate situation during its winter dormancy. I am fond enough of its sky blue flowers to propagate a few more copies of it.

The delicate pastel blue flowers are prettier up close.

Six on Saturday: Glad

Butterfly gladiolus will not bloom for a while. Abyssinian gladiolus may not bloom at all. Hybrid gladiolus, though, are already finishing. I got these few pictures while I can, and will likely get pictures of butterfly gladiolus as they bloom later. I am glad to do so. They are my favorite gladiolus. They are more like wildflowers than overly bred hybrids. Also, they are very reliably perennial. I hope that the Abyssinian gladiolus perform also. They are also supposedly reliably perennial, but are not in a very good situation here. I should relocate them, perhaps closer to where the butterfly gladiolus are so happy. The hybrids are earning my appreciation too. I was not aware that they had potential to be perennial.

1. Gladiolus papilio, butterfly gladiolus is my favorite, because it is from Tangly Cottage Gardening, is approved by Skooter, is reliably perennial, and it blooms like a wildflower.

2. Its foliage is rather grassy, which is more compatible with other wildflowers than wide leaves of more garish hybrid gladiolus. The corms multiply and migrate quite efficiently.

3. Gladiolus murielae, Abyssinian gladiolus is my second favorite, even while it is not so much to see. It is a gift from a neighbor. It should bloom for autumn, but I have doubts.

4. Hybrid gladiolus are the most colorful, but are not reliably perennial. However, these and two others have been blooming well here for several years, and actually multiplying.

5. This orange with yellow hybrid gladiolus was one of the first two to bloom again after a few years of producing only foliage. The yellow gladiolus joined them a few years later.

6. This purple hybrid gladiolus is the other of the first pair to resume bloom, although it does not multiply as much as the yellow gladiolus that resumed bloom a few years later.

Thrift

Thrift performs well in coastal climates.

When I see common thrift, Armeria maritima, in nurseries now, I wonder what such a diminutive perennial would be useful for. Their densely compact mounds of narrow evergreen leaves rarely get more than four inches deep, and take their time spreading to less than a foot wide. Then I remember how thrift visually softened the straight edges of my father’s brick patio and retaining walls, and fit so nicely into the tight spots. If allowed to do so, thrift creeps slowly over edges of pavement and stepping stones, but is not too eager to overwhelm them.

If it eventually gets overgrown, thrift is easily cut back to the edge of pavement at the end of winter, and will green over its raw edge by spring. The bits and pieces that are left over from cutting back the edges can be plugged back into other areas and will eventually develop roots if initially watered regularly. Once established, thrift stays healthier if allowed to dry somewhat between watering. Bald spots that may naturally come and go as mature plants die out in the center and then regenerate fill in faster if outer edges get cut back.

The dense round clusters of tiny flowers stand above the foliage on bare stems about four to eight inches high. The flowers are almost always bright pink, but are sometimes white or reddish pink. Bloom is most profuse in spring and may continue sporadically all year.

Clematis

Clematis like warm air but cool soil.

Like the big bark of a little terrier, the big and boldly colored flowers of large-flowered hybrid clematis seem to be more than their delicate vines should be able to produce. Almost all of the many modern varieties bloom with flowers that are at least three inches wide; and some have slightly ruffled double flowers. Their rich, deep, and sometimes two toned shades of red, blue, purple or pink, as well as white seem too opulent for their simple wiry stems that may climb to only six feet or so. The dark green compound leaves grab harmlessly onto light trellises, stakes or lattice.
Although the foliage and flowers want sunny exposure, clematis roots do not like warm soil, so appreciate generous mulching.  Some people like to give them a wide rock to disperse their roots under, or plant them next to large pots that sit directly on the soil. I planted mine on the north side of the northwestern corner of the house where the soil was always shaded, and allowed it to climb around the corner onto an iron banister on the west side.

Clematis want to be watered and fertilized regularly, and well drained organically rich soil. They should be pruned rather aggressively in winter while they seem to be dead, but are really just dormant.

Perennial Annuals

New Guinea impatiens (with ivy geranium) from last year.

Annuals complete their entire lifespans within a single year.

Perennials survive for more than a single year.

Biennials grow vegetatively during their first year, and then bloom, disperse seed and die during their second year, but that is another story.

Most species that are appreciated as annuals here actually have potential to be perennials, even if only short term perennials. They are only replaced annually because it is easier than maintaining them through their dormant season.

For example, busy Lizzy is a warm season annual that gets installed for spring and replaced with cool season annuals for autumn. However, if cut back and sheltered from frost, it can survive through winter to perform for the following spring and summer. Actually, it can survive perennially like this for quite a few years, and as it ultimately deteriorates, it can replace itself with its own cuttings or layered stems.

Brent did this with New Guinea impatiens from last year. He neglected to replace them for winter (which is quite brief there), and then noticed that they resumed growth as winter ended. Now, they are huge and even more spectacularly florific than they were last summer.

The picture above shows where I camp out in his backyard when I go to Southern California. Most of the white bloom to the right is actually ivy geranium that cascades below the New Guinea impatiens, but most of the white bloom to the left is New Guinea impatiens above ivy geranium. (White on white was not quite as monotonous when each of the two species maintained its distinct form last year.)

Small terrace at the western margin of the garden.

This other pair of potted dwarf Alberta spruce surrounded with the same New Guinea impatiens above, with a close up below, flanks the steps to a small terrace at far western margin of the garden.

These New Guinea impatiens are huge because they resumed growth from last year.

Six on Saturday: Mostly Flowers

Simply, these are six varieties of flowers. All but one bloomed last week. Half are hybrid cultivars of the same genus with two in the same picture. Six pictures of flowers with two varieties in one picture should include seven varieties of flowers. But of course, “mostly” indicates something that is not exclusive. Anyway, I should have gotten more pictures at work, since it was a rather fun week. Irrigation is getting more demanding, though, now that the weather is getting warmer. Because we need to delay renovation of a prominent landscape, we installed potted Canna onto the site. They are potted to facilitate removal when renovation resumes, but will be rad!

1. Lantana camara, which is known here simply as ‘lantana’, is too colorful to not share. Actually though, it is from three weeks ago, and west of Phoenix. Ours is more yellowish.

2. Rosa ‘Iceberg’ and ‘Burgundy Iceberg’ are grafted together on two old rose trees in the rose garden. I find multiple grafts to be annoying, but guests find them to be intriguing.

3. Rosa of an unidentified cultivar blooms better with better exposure, and also without the other cultivar that it was originally grafted with, but that was crowded out years ago.

4. Alstroemeria peruviana, Peruvian lily will not die. We removed large colonies at least twice from this location, but some always survive. They are yellow, orange, pink and red.

5. Lilium, which seems to be some sort of fancy Asiatic lily, was a gift from a neighbor. I did not expect them to perform so well, but after only four years, they should be divided.

6. Rhody is the only one of these six who is not a flower, although another type of flower is named after him. Morgan, his F250 who identifies as a Mercury, wants to get washed.
